The WH-9200AP is equipped with 2 high-powered Atheros radios. The radio 1 runs in the

11a 5GHz mode only while the radio 2 runs at the 11a/b/g dual band mode. AirLive adds high power amplifier to run the AP at 23dBm in 11a mode (200mW), that’s 4 times the output power of normal 11a radio (50mW). In addition, 2 programmable LAN ports are available for multi-mode AP/Gateway configuration.

Multiple Operation Modes

The WH-9200AP can operate in multiple wireless modes for different application environments such as Dual AP, Dual WDS, Duplex link aggregation, Separate Bridge, AP +

Client, AP + WDS, WDS + Gateway, AP + Gateway, and AP + WISP. These modes can be changed and configured easily by the Web user interface.

802.3af PoE Port

WH-9200AP is equipped with an 802.3af Power over Ethernet port. It thus can be powered by a PoE PSE and operate at up to 100 meter away.

VLAN & QoS

WH-9200AP provides Multi-SSID to create different wireless networks using one AP. The

TAG VLAN feature allows service provider to control service content of each SSID network all the way back to core router. The QoS feature allows prioritizing the different package according the 802.11e WMM protocol and triple play (Voice, Video and Data). Bandwidth control feature allow WH-9200AP to limit the bandwidth on distinct IP/MAC or on the total device.

3.6 Wireless Security

The wireless security is to configure a secure connection between two wireless devices.

WH-9200AP provides WEP, 802.1x,

WPA, WPA-PSK, WPA2,

WPA2-PSK, WPA-AUTO and

WPA-PSK-AUTO security policy.

WEP

WEP allows you to use data encryption to secure your data from being eavesdropped by malicious people. It allows 3 types of key: 64 (WEP64), 128 (WEP128), and 152 (WEP152) bits. You can configure up to 4 keys using either ASCII or Hexadecimal format.

Key Settings: The length of a

WEP64 key must be equal to 5 bytes, a WEP128 key is 13 bytes, and a WEP152 key is 16 bytes.

Key Index: You have to specify which of the four keys will be active.

Once you enable the WEP function, please make sure that both the WH-9200AP and the wireless client stations use the same key.

Some wireless client cards only allow Hexadecimal digits for WEP keys.

Please note that when configuring WEP keys, a WEP128 ASCII key looks like “This is a key”(13 characters), while a WEP128 Hex key looks like “546869732069732061206b6579”(26 HEX)

(hexadecimal notation are 0-9 and A-F).



802.1X

802.1x allows users to leverage a RADIUS server to do association authentications. You can also enable dynamic WEP key (128 bit) to have data encryption. Here you do not have to enter the WEP key manually because it will be generated automatically and dynamically.

Rekey interval is time period that the system will change the key periodically. The shorter the interval is, the better the security is.

Server IP and Shared Secret:

If you have connect AP to a

RADIUS server behind, key in the Server IP and share secret, it will redirect incoming connection request first to this

RADIUS for Authentication. In general you don’t have to change Port Number, which is 1812 by default and used by most

RADIUS server.

After you have finished the configuration wizard, you have to configure the RADIUS

Settings in Advanced Settings in order to make the 802.1x function work.

Share secret is the key for AP to communicate with RADIUS server, check with your

Authentication provider for more details.



WPA

Wi-Fi Protected Access (WPA) requires a RADIUS server available in order to do authentication (same as 802.1x), thus there is no shared key required.

Encryption Type: There are two encryption types TKIP and CCMP (AES). While CCMP provides better security than TKIP, some wireless client stations may not be equipped with the hardware to support it. You can select Both to allow TKIP clients and CCMP clients to connect to the Access Point at the same time.

Group Rekey Interval: A group key is used for multicast/broadcast data, and the re-key interval is time period that the system will change the group key periodically. The shorter the interval is, the better the security is. The default is 300 sec.

WPA-PSK

Wi-Fi Protected Access (WPA) with Pre-Shared Key (PSK) provides better security than

WEP keys. It does not require a RADIUS server in order to provide association authentication, but you do have to enter a shared key for the authentication purpose. The encryption key is generated automatically and dynamically.



Pre-shared Key: This is an ASCII string with 8 to 63 characters. Please make sure that both the WH-9200AP and the wireless client stations use the same key.



WPA2

WPA2 stands for Wi-Fi Protected Access 2. It provides stronger data protection and network access control then WPA. Only authorized users can access the wireless networks.





WPA2-PSK

Enter the Pre-shared Key to initiate WPA2 security. All devices try to access the network should have the matching encryption key.






WPA-AUTO





WPA-PSK-AUTO

WPA-PSK-AUTO tries to authenticate wireless clients using WPA-PSK or WPA2-PSK.






3.7 Advanced Wireless Settings

When click on Advanced Setup button under client mode, a pop-up window appears and show parameter as follow:



Beacon Interval: The

WH-9200AP broadcasts beacon frames regularly to announce its existence. The beacon Interval specifies how often beacon frames are transmitted in time unit of milliseconds.

RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmission. Any unicast (data or control) frames larger than specified RTS threshold must be transmitted following the RTS/CTS handshake exchange mechanism.

The RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It is recommended that this value does not deviate from the default too much.

Fragmentation: When the size of a unicast frame exceeds the fragmentation threshold, it will be fragmented before the transmission. It should have a value of 256-2346 bytes, with a default of 2346. If you experience a high packet error rate, you should slightly decrease the

Fragmentation Threshold.

DTIM Interval: The WH-9200AP buffers packets for stations that operate in the power-saving mode. The Delivery Traffic Indication Message (DTIM) informs such power-conserving stations that there are packets waiting to be received by them. The DTIM interval specifies how often the beacon frame should contain DTIMs.

User Limitation: The range of user limitation is from 1 to 100.

Age Out Timer: Set the age out time. The default is 300 sec.



Transmit Power: Transmit power output depends upon the size and RF characteristics because that will determine the number of APs, channels, and need for antennas.

Rate Control: Limit the wireless data rate to the selected number.

Enable STP: Spanning Tree Protocol prevents the condition known as a bridge loop.

Ack TimeOut: The "ACK time-out" determines how long the program waits after receiving a packet from a file stream to determine that stream to be a complete file.

The following windows pops up when click on “ACK Calculator” button:

Fill the distance from your location to the remote access point

In the field of “Distance”, input the distance in “meters”.

After input the distance value, move the cursor to any place on the pop-up window out of three fields. The calculated value will display.


The ACK value then shows up after calculating


Enter the calculated value of “AckTimeOut” into the appropriate “Ack TimeOut” field (11a or 11g) in the “Advanced Wireless Settings” window.

Change the value from 25 to 107, where 107 is calculated value of distanced 12500m.

3.8 Access Control

The WH-9200AP allows you to define a list of MAC addresses that are allowed or denied to access the wireless network. Click on the setup button of “Access Control” of selected wireless interface.

Disable MAC address control list: When selected, no MAC address filtering will be performed.



Enable GRANT address control list: When selected, data traffic from only the specified devices in the table will be allowed in the network.

Enable DENY address control list: When selected, data traffic from the devices specified in the table will be denied/discarded by the network.

To add a MAC address into the table, enter a Mnemonic Name and the MAC Address, and then click ADD. The table lists all configured MAC Filter entries.

To delete entries, check the corresponding Select boxes and then press DELETE

SELECTED.



3.9 Bandwidth Control

Bandwidth Control is a great tool to control the bandwidth of the WISP subscribers.

Therefore, the WISP operators can offer different class of connection speeds for different subscription fees - just like the ADSL service! The AirLive advance firmware can control the bandwidth by Interface or IP/MAC.

There are 2 types of Traffic Control it offers: Total bandwidth control and Per-use bandwidth control.



3.9.1 Total Bandwidth Control

The total bandwidth controls the data rate at either Wired or Wireless interface.

The following example limit the download bandwidth to 1024kbps and uplink to 512kbps

Example1: 3 wireless clients share downlink and uplink bandwidth.

To change the password, press the Password Settings button to enter the Password Settings screen; then enter the Current Password followed by the New Password twice. The entered characters will appear as asterisks.



4.2 System Management Settings

The WH-9200AP allow you to change the parameter of manage the system.

HTTP Port No.: This is to change the management web port of WH-9200AP. By default, the port number is 80 and we type http://192.168.1.1 in the browser to access the management web page. If we change the port to another, say, 90, then we need to type http://192.168.1.1:90 instead. This prevents unwelcome access to the management interface.

Time-out: The default is 10 minutes. If you idle on the web management interface more than 10 minutes, the system log you out and you need to login again.

UPnP: The Universal Plug and Play (UPnP) feature allows a Windows XP/ME PC to discover this WH-9200AP and automatically show an icon on the screen. Then a user can double-click the icon to access this device directly (without having to find out its IP address).



Syslog: If the Syslog is Enabled, WH-9200AP create a log in the system log table when encounters an error or warning condition. This apply to IETF (Internet Engineering Task

Force - the Internet standards body)-conformant standard for logging system events

(RFC-3164)

Syslog server IP address: The Syslog can also send to the identified IP address.

The system log shows in WH-9200AP:

Community String For Write: For read-write operation, you need to configure a write

“community string”.

Assign a specific name and IP address for your SNMP trap manager:



A trap manager is a remote SNMP management station where special SNMP trap messages are generated (by the router) and sent to in the network.

You can define trap managers in the system.

You can add a trap manager by entering a name, an IP address, followed by pressing the

ADD button.

You can delete a trap manager by selecting the corresponding entry and press the

DELETE SELECTED button.

To enable a trap manager, check the Enable box in the corresponding entry; to disable it, un-check the Enable box.

Some extra feature of WH-9200AP does not show in the wizard because some higher knowledge of parameters of them is required. They are classified in the tab of “Advances

Setting”, such as the Multi SSID for VLAN setting and 802.11e QoS configuration.

4.4 Firmware Upgrade

You can upgrade the firmware of your WH-9200AP (the software that controls your

WH-9200AP’s operation). Normally, this is done when a new version of firmware offers new features that you want, or solves problems that you have encountered with the current version. System upgrade can be performed through the System Upgrade window as follows:



To update the WH-9200AP firmware, first download the firmware from the distributor’s web site to your local disk, and then from the above screen enter the path and filename of the firmware file (or click Browse to locate the firmware file). Next, Click the Upgrade button to start.

The new firmware will be loaded to your WH-9200AP. After a message appears telling you that the operation is completed, you need to reset the system to have the new firmware take effect.

Do not power off the device while upgrading the firmware.

It is recommended that you do not upgrade your WH-9200AP unless the new firmware has new features you need or if it has a fix to a problem that you’ve encountered.

4.5 Configuration Save and Restore

In this interface, you can backup your system configuration to PC and restore your saved configuration file to the WH-9200AP.

To save the configuration to your PC, click the “SAVE TO FILE” button and the system will

6. Wireless Network Glossary

6 6.

Wireless Network

Glossary

The wireless network glossary contains explanation or information about common terms used in wireless networking products. Some of information in this glossary might be outdated, please use with caution.

802.11a

An IEEE specification for wireless networking that operates in the 5 GHz frequency range

(5.15 GHz to 5.850 GHz) with a maximum of 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz band. In addition, the 802.11a have 12 non-overlapping channels, comparing to 802.11b/g's 3 non-overlapping channels. This means the possibility to build larger non-interfering networks. However, the 802.11a deliver shorter distance at the same output power when comparing to 802.11g.

802.3ad

802.3ad is an IEEE standard for bonding or aggregating multiple Ethernet ports into one virtual port (also known as trunking) to increase the bandwidth.

802.3af

This is the PoE (Power over Ethernet) standard by IEEE committee. 803.af uses 48V

POE standard that can deliver up to 100 meter distance over Ethernet cable.

802.11b

International standard for wireless networking that operates in the 2.4 GHz frequency band

(2.4 GHz to 2.4835 GHz) and provides a throughput up to 11 Mbps.

802.1d STP

Spanning Tree Protocol. It is an algorithm to prevent network from forming. The STP protocol allows net work to provide a redundant link in the event of a link failure. It is advise to turn on this option for multi-link bridge network.



802.11d

Also known as “Global Roaming”. 802.11d is a standard for use in countries where systems using other standards in the 802.11 family are not allowed to operate.

802.11e

The IEEE QoS standard for prioritizing traffic of the VoIP and multimedia applications.

The WMM is based on a subset of the 802.11e.

802.11g

A standard provides a throughput up to 54 Mbps using OFDM technology. It also operates in the 2.4 GHz frequency band as 802.11b. 802.11g devices are backward compatible with 802.11b devices.

802.11h

This IEEE standard define the TPC (transmission power control) and DFS(dynamic frequency selection) required to operate WiFi devices in 5GHz for EU.

802.11i

The IEEE standard for wireless security. 802.11i standard includes TKIP, CCMP, and

AES encryption to improve wireless security. It is also know as WPA2.

802.1Q Tag VLAN

In 802.1Q VLAN, the VLAN information is written into the Ethernet packet itself. Each packet carries a VLAN ID(called Tag) as it traveled across the network. Therefore, the

VLAN configuration can be configured across multiple switches. In 802.1Q spec, possible

4096 VLAN ID can be created. Although for some devices, they can only view in frames of 256 ID at a time.

802.1x

802.1x is a security standard for wired and wireless LANs. In the 802.1x parlance, there are usually supplicants (client), authenticator (switch or AP), and authentication server (radius server) in the network. When a supplicants request a service, the authenticator will pass the request and wait for the authentication server to grant access and register accounting.

The 802.1x is the most widely used method of authentication by WISP.



Adhoc

A Peer-to-Peer wireless network. An Adhoc wireless network do not use wireless AP or router as the central hub of the network. Instead, wireless client are connected directly to each other. The disadvantage of Adhoc network is the lack of wired interface to Internet connections. It is not recommended for network more than 2 nodes.

Access Point (AP)

The central hub of a wireless LAN network. Access Points have one or more Ethernet ports that can connect devices (such as Internet connection) for sharing. Multi-function

Access Point can also function as an Ethernet client, wireless bridge, or repeat signals from other AP. Access Points typically have more wireless functions comparing to wireless routers.

ACK Timeout

Acknowledgement Timeout Windows. When a packet is sent out from one wireless station to the other, it will waits for an Acknowledgement frame from the remote station. The station will only wait for a certain amount of time, this time is called the ACK timeout. If the

ACK is NOT received within that timeout period then the packet will be re-transmitted resulting in reduced throughput. If the ACK setting is too high then throughput will be lost due to waiting for the Ack Window to timeout on lost packets. If the ACK setting is too low then the ACK window will have expired and the returning packet will be dropped, greatly lowering throughput. By having the ability to adjust the ACK setting we can effectively optimize the throughput over long distance links. This is especially true for 802.11a and

802.11g networks. Setting the correct ACK timeout value needs to consider 3 factors: distance, AP response time, and interference. The WH-9200AP provides ACK adjustment capability in form of either distance or direct input. When you enter the distance parameter, the WH-9200AP will automatically calculate the correct ACK timeout value.

Bandwidth Management

Bandwidth Management controls the transmission speed of a port, user, IP address, and application. Router can use bandwidth control to limit the Internet connection speed of individual IP or Application. It can also guarantee the speed of certain special application or privileged IP address - a crucial feature of QoS (Quality of Service) function. The

WH-9200AP’s features both “Per-user Bandwidth Control” and “Total Bandwidth Control”.

“Per-user Bandwidth Control” allow administrator to define the maximum bandwidth of each user by IP, IP Group, or MAC address. Total Bandwidth defines the maximum bandwidth of wireless or Ethernet interface.



Bootloader

Bootloader is the under layering program that will start at the power-up before the device loads firmware. It is similar to BIOS on a personal computer. When a firmware crashed, you might be able to recover your device from bootloader.

Bridge

A product that connects 2 different networks that uses the same protocol. Wireless bridges are commonly used to link network across remote buildings. For wireless application, there are 2 types of Bridges. WDS Bridge can be used in Point-to-Point or

Point-to-Multipoint topology. Bridge Infrastructure works with AP mode to form a star topology.

Cable and Connector Loss: During wireless design and deployment, it is important to factor in the cable and connector loss. Cable and connector loss will reduce the output power and receiver sensitivity of the radio at connector end. The longer the cable length is, the more the cable loss. Cable loss should be subtracted from the total output power during distance calculation. For example, if the cable and connector loss is 3dBm and the output power is 20dBm; the output power at the cable end is only 17dBm.

Client

Client means a network device or utility that receives service from host or server. A client device means end user device such as wireless cards or wireless CPE.

CPE Devices

CPE stands for Customer Premises Equipment. A CPE is a device installed on the end user's side to receive network services. For example, on an ADSL network, the ADSL modem/router on the subscriber's home is the CPE device. Wireless CPE means a complete Wireless (usually an AP with built-in Antenna) that receive wireless broadband access from the WISP. The opposite of CPE is CO.

CTS

Clear To Send. A signal sent by a device to indicate that it is ready to receive data.

DDNS

Dynamic Domain Name System. An algorithm that allows the use of dynamic IP address


6. Wireless Network Glossary for hosting Internet Server. A DDNS service provides each user account with a domain name. A router with DDNS capability has a built-in DDNS client that updates the IP address information to DDNS service provider whenever there is a change. Therefore, users can build website or other Internet servers even if they don't have fixed IP connection.

DHCP

Dynamic Hosting Configuration Protocol. A protocol that enables a server to dynamically assign IP addresses. When DHCP is used, whenever a computer logs onto the network, it automatically gets an IP address assigned to it by DHCP server. A DHCP server can either be a designated PC on the network or another network device, such as a router.

DMZ

Demilitarized Zone. When a router opens a DMZ port to an internal network device, it opens all the TCP/UDP service ports to this particular device. The feature is used commonly for setting up H.323 VoIP or Multi-Media servers.

DNS

A program that translates URLs to IP addresses by accessing a database maintained on a collection of Internet servers.

Domain Name

The unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. In www.airlive.com, the "airlive.com" is the doman name.

DoS Attack

Denial of Service. A type of network attack that floods the network with useless traffic.

Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols.

Encryption

Encoding data to prevent it from being read by unauthorized people. The common wireless encryption schemes are WEP, WPA, and WPA2.



ESSID (SSID)

The identification name of an 802.11 wireless network. Since wireless network has no physical boundary liked wired Ethernet network, wireless LAN needs an identifier to distinguish one network from the other. Wireless clients must know the SSID in order to associate with a WLAN network. Hide SSID feature disable SSID broadcast, so users must know the correct SSID in order to join a wireless network.

Firewall

A system that secures a network and prevents access by unauthorized users. Firewalls can be software, router, or gateway. Firewalls can prevent unrestricted access into a network, as well as restricting data from flowing out of a network.

Firmware

The program that runs inside embedded device such as router or AP. Many network devices are firmware upgradeable through web interface or utility program.

FTP

File Transfer Protocol. A standard protocol for sending files between computers over a

TCP/IP network and the Internet.

Fragment Threshold

Frame Size larger than this will be divided into smaller fragment. If there are interferences in your area, lower this value can improve the performance. If there are not, keep this parameter at higher value. The default size is 2346. You can try 1500, 1000, or 500 when there are interference around your network.

Full Duplex

The ability of a networking device to receive and transmit data simultaneously. In wireless environment, this is usually done with 2 or more radios doing load balancing.

Gateway

In the global Internet network, the gateways are core routers that connect networks in different IP subnet together. In a LAN environment with an IP sharing router, the gateway is the router. In an office environment, gateway typically is a multi-function device that integrates NAT, firewall, bandwidth management, and other security functions.



Hotspot

A place where you can access Wi-Fi service. The term hotspot has two meanings in wireless deployment. One is the wireless infrastructure deployment, the other is the

Internet access billing system. In a hotspot system, a service provider typically need an authentication and account system for billing purposes, and a wireless AP network to provide access for customers.

IGMP Snooping

Internet Group Management Protocol (IGMP) is a Layer 3 protocol to report IP multicast memberships to neighboring multicast switches and routers. IGMP snooping is a feature that allows an Ethernet switch to "listen in" on the IGMP conversation between hosts and routers. A switch support IGMP snooping has the possibility to avoid multicast traffic being treated as broadcast traffic; therefore, reducing the overall traffic on the network.

Infrastructure Mode

A wireless network that is built around one or more access points to provide wireless clients access to wired LAN / Internet service. The opposite of Infrastructure mode is Adhoc mode.

IP address

IP (Internet Protocol) is a layer-3 network protocol that is the basis of all Internet communication. An IP address is 32-bit number that identifies each sender or receiver of information that is sent across the Internet. An IP address has two parts: an identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. The new IPv6 specification supports 128-bit

IP address format.

IPsec

IP Security. A set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private

Networks (VPNs). IPsec supports two encryption modes: Transport and Tunnel.

Transport mode encrypts only the data of each packet, but leaves the header untouched.

The more secure Tunnel mode encrypts both the header and the payload. On the receiving side, an IPSec-compliant device decrypts each packet.

LACP (802.3ad) Trunking



The 802.3ad Link Aggregation standard defines how to combine the several Ethernet ports into one high-bandwidth port to increase the transmission speed. It is also known as port trunking. Both device must set the trunking feature to work.

MAC

Media Access Control. MAC address provides layer-2 identification for Networking Devices.

Each Ethernet device has its own unique address. The first 6 digits are unique for each manufacturer. When a network device have MAC access control feature, only the devices with the approved MAC address can connect with the network.

Mbps

Megabits Per Second. One million bits per second; a unit of measurement for data transmission

MESH

Mesh is an outdoor wireless technology that uses Spanning Tree Protocol (STP) and

Wireless Distribution system to achieve self-forming, self-healing, and self-configuring outdoor network. MESH network are able to take the shortest path to a destination that does not have to be in the line of site.

MIMO

NAT

Network Address Translation. A network algorithm used by Routers to enables several

PCs to share single IP address provided by the ISP. The IP that a router gets from the

ISP side is called Real IP, the IP assigned to PC under the NAT environment is called

Private IP.

Node

A network connection end point, typically a computer.



Packet

A unit of data sent over a network.

Passphrase

Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for the company products.

POE

Power over Ethernet. A standard to deliver both power and data through one single

Ethernet cable (UTP/STP). It allows network device to be installed far away from power ource. A POE system typically compose of 2 main component: DC Injector (Base Unit) and Splitter(Terminal Unit). The DC injector combines the power and data, and the splitter separates the data and power back. A PoE Access Point or CPE has the splitter built-in to the device. The IEEE 802.3af is a POE spec that uses 48 volt to deliver power up to 100 meter distance.

Port

This word has 2 different meaning for networking. z The hardware connection point on a computer or networking device used for plugging in a cable or an adapter. z The virtual connection point through which a computer uses a specific application on a server.

PPPoE

Point-to- Point Protocol over Ethernet. PPPoE relies on two widely accepted standards:

PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the

Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem.

PPTP

Point-to-Point Tunneling Protocol: A VPN protocol developed by PPTP Forum. With

PPTP, users can dial in to their corporate network via the Internet. If users require data encryption when using the Windows PPTP client, the remote VPN server must support

MPPE (Microsoft Point-To-Point Encryption Protocol) encryption. PPTP is also used by some ISP for user authentication, particularly when pairing with legacy Alcatel / Thomson

ADSL modem.



Preamble Type

Preamble are sent with each wireless packet transmit for transmission status. Use the long preamble type for better compatibility. Use the short preamble type for better performance

Rate Control

Ethernet switches' function to control the upstream and downstream speed of an individual port. Rate Control management uses "Flow Control" to limit the speed of a port.

Therefore, the Ethernet adapter must also have the flow control enabled. One way to force the adapter's flow control on is to set a port to half-duplex mode.

RADIUS

Remote Authentication Dial-In User Service. An authentication and accounting system used by many Internet Service Providers (ISPs). When you dial in to the ISP, you must enter your username and password. This information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access to the ISP system.

Radius typically uses port 1812 and port 1813 for authentication and accounting port.

Though not an official standard, the RADIUS specification is maintained by a working group of the IETF.

Receiver Sensitivity

Receiver sensitivity means how sensitive is the radio for receiving signal. In general; the slower the transmission speed, the more sensitive the radio is. The unit for Receiver

Sensitivity is in dB; the lower the absolute value is, the higher the signal strength. For example, -50dB is higher than -80dB.

RJ-45

Standard connectors for Twisted Pair copper cable used in Ethernet networks. Although they look similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to eight wires, whereas telephone connectors have only four.

Router

An IP sharing router is a device that allows multiple PCs to share one single broadband connection using NAT technology. A wireless router is a device that combines the


6. Wireless Network Glossary functions of wireless Access Point and the IP sharing router.

RSSI

Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the remote wireless device. In general, remote APs with stronger signal will display higher RSSI values. For RSSI value, the smaller the absolute value is, the stronger the signal. For example, “-50db” has stronger signal than “-80dB”. For outdoor connection, signal stronger than -60dB is considered as a good connection.

RTS

Request To Send. A packet sent when a computer has data to transmit. The computer will wait for a CTS (Clear To Send) message before sending data.

RTS Threshold

RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a frame if the packet frame is larger than this value. Lower this value can improve the performance if there are many clients in your network. You can try 1500, 1000 or 500 when there are many clients in your AP’s network.

SNMP

Simple Network Management Protocol. A set of protocols for managing complex networks. The SNMP network contains 3 key elements: managed devices, agents, and network-management systems (NMSs). Managed devices are network devices that content SNMP agents. SNMP agents are programs that reside SNMP capable device's firmware to provide SNMP configuration service. The NMS typically is a PC based software such as HP Openview that can view and manage SNMP network device remotely.

SSH

Developed by SSH Communications Security Ltd., Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist.

SSL

Secure Sockets Layer. It is a popular encryption scheme used by many online retail and banking sites to protect the financial integrity of transactions. When an SSL session


6. Wireless Network Glossary begins, the server sends its public key to the browser. The browser then sends a randomly generated secret key back to the server in order to have a secret key exchange for that session. SSL VPN is also known as Web VPN. The HTTPS and SSH management interface use SSL for data encryption.

Subnet Mask

An address code mask that determines the size of the network. An IP subnet are determined by performing a BIT-wise AND operation between the IP address and the subnet mask. By changing the subnet mask, you can change the scope and size of a network.

Subnetwork or Subnet

Found in larger networks, these smaller networks are used to simplify addressing between numerous computers. Subnets connect to the central network through a router, hub or gateway. Each individual wireless LAN will probably use the same subnet for all the local computers it talks to.

Super A

Super A is an Atheros proprietary turbo mode to increase speed over standard 802.11a mode. It adds Bursting and Compression to increase the speed. If you live in countries that prohibit the channel binding technology (i.e. Europe), you should choose “Super-A without Turbo) if you need more speed than 11a mode

TCP

While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the packets that a message is divided into for efficient routing through the Internet.

Turbo A

Turbo A is an Atheros proprietary turbo mode to increase speed over standard 802.11a mode. It uses channel binding technology to increase speed. There are 2 types of Turbo

A modes: Dynamic Turbo and Static Turbo. In Dynamic Turbo, the channel binding will be used only if necessary. In Static Turbo, the channel binding is always on. This protocol may be combined with Super-A model to increase the performance even more. The used of channel binding might be prohibited in EU countries.
