1.7 Applications

The wireless LAN products are easy to install and highly efficient. The following list describes some of the many applications made possible through the power and

10

flexibility of wireless LANs:

a) Difficult-to-wire environments

There are many situations where wires cannot be laid easily. Historic buildings, older buildings, open areas and across busy streets make the installation of LANs either impossible or very expensive.

b) Temporary workgroups

Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery, temporary offices and construction sites where one wants a temporary WLAN established and removed.

c) The ability to access real-time information

Doctors/nurses, point-of-sale employees, and warehouse workers can access real-time information while dealing with patients, serving customers and processing information

.

d) Frequently changed environments

Show rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange the workplace.

e) Small Office and Home Office (SOHO) networks

SOHO users need a cost-effective, easy and quick installation of a small network.

f) Wireless extensions to Ethernet networks

Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs.

g) Wired LAN backup

Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks.

h) Training/Educational facilities

Training sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges, and learning.

11

1.8 Network Configuration

To better understand how the wireless LAN products work together to create a wireless network, it might be helpful to depict a few of the possible wireless LAN PC card network configurations. The wireless LAN products can be configured as: a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs. b) Infrastructure for enterprise LANs. c) Wi-Fi Mesh Networks

a) Ad-hoc (peer-to-peer) Mode

This is the simplest network configuration with several computers equipped with the

PC Cards that form a wireless network whenever they are within range of one another.

In ad-hoc mode, each client is peer-to-peer, would only have access to the resources of the other client and does not require an access point. This is the easiest and least expensive way for the SOHO to set up a wireless network. The image below depicts a network in ad-hoc mode.

b) Infrastructure Mode

The infrastructure mode requires the use of an access point (AP). In this mode, all wireless communication between two computers has to be via the AP. It doesn’t matter if the AP is stand-alone or wired to an Ethernet network. If used in stand-alone, the AP can extend the range of independent wireless LANs by acting as a repeater, which effectively doubles the distance between wireless stations. The image below depicts a network in infrastructure mode.

12

c) Wi-Fi Mesh Networks

A Wireless Mesh Network constructed from WiFi Technology alleviates a number of roaming challenges from laptops, IP phones, PDAs, and IP base devices:

No geographical limitations – User can take a handheld or laptop computer anywhere without losing the connection in their home

No physical connection required – Mobile IP connects automatically and obtains local

IP router information

Supports security – Authentication is performed to ensure that rights are being protected

Access Anytime, Anywhere – Network access is assured at all times and from all locations. No missed E-mails and increase productivity due to constant connectivity.

Emergencies – Rapidly deployable and robust communications between each member when emergencies are involved in difficult operations inside buildings, towers, or surrounded in forest fires

Military Usage – Soldiers in a battlefield are exchanging information about their position and giving and receiving orders, or the instructions

The connection is established for the duration of one session by discovering others device within range. WLAN 2 defined as AP mode. AP mode will bring the wireless device to Access Point mode. Under this mode, it can connect multiple wireless communication devices together to form a wireless network can relay data between wireless and wired devices.

26

 Band: Select a wireless band from the drop-down list: 802.11a, 802.11b, or

802.11g.

 ESSID: The SSID is a unique named shared amongst all the points of the wireless network. The SSID must be identical on all points of the wireless network and cannot exceed 32 characters

 Frequency: Select a frequency/channel from the drop-down list. The channels available are based on the country’s regulation. A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network.

 Beacon Period: Beacons are packets sent by a wireless Access Point to synchronize wireless devices. Specify a Beacon Period value between 20 and

1000. The default value is set to 100 milliseconds.

 RTS Threshold: Packets over the specified size will use the RTS/CTS mechanism to maintain performance in noisy networks and preventing hidden nodes from degrading the performance. Specify a value between 1 and 65535.

The default value is 2346.

 Fragment Threshold: Packets over the specified size will be fragmented in order to improve performance on noisy networks. Specify a value between 256 and 65535. The default value is 2346.

 DTIM Interval: A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the wireless

Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1.

 Data rate: Select a data rate from the drop-down list or select auto.

 Diversity: A method for improving the reliability of a message signal by utilizing two or more communication channels with different characteristics,

27

in order to combat fading and interference. Click on “Diversity” drop down button to select “Card Default”, “Enable” or “Disable”.

 Base Datarate max Tx power: Default output power of the device.

 Current Datarate max Tx power: You may control the output power of the device by selecting a value from the drop-down list.

 Security: You may select WEP or WPA security. WEP is an acronym for

Wired Equivalent Privacy, and is a security protocol that provides the same level of security for wireless networks as for a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption.

Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information

Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network.

 Encryption Key: Specify the WEP encryption key.

 WPA Security: You may select WEP or WPA security. WPA (Wi-Fi Protected

Access) was designed to improve upon the security features of WEP (Wired

Equivalent Privacy). The technology is designed to work with existing Wi-Fi products that have been enabled with WEP. WPA provides improved data encryption through the Temporal Integrity Protocol (TKIP), which scrambles the keys using a hashing algorithm and by adding an integrity checking feature which makes sure that keys haven’t been tampered with.

 WPA Type: The encryption algorithm used to secure the data communication.

28

TKIP (Temporal Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES (Advanced Encryption Standard) is a very secure block based encryption. Note that, if the bridge uses the AES option, the bridge can associate with the access point only if the access point is also set to use only AES. The device negotiates the cipher type with the access point, and uses AES when available.

 802.1x: This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have established the necessary credentials before attempting to authenticate to the Server through this Gateway.

Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate users.

 Encryption Key: Specify the WPA encryption key.

 Click on the Save Changes button to store and changes and then reboot the device in order for the changes to take effect.
