Wireless Local Area Networks

Wireless local area networks (WLANs) allow the device to communicate wirelessly inside a building.

Before using the device on a WLAN, the facility must be set up with the required hardware to run the

WLAN (sometimes known as infrastructure). The infrastructure and the device must both be properly configured to enable this communication.

Refer to the documentation provided with the infrastructure (access points (APs), access ports, switches,

Radius servers, etc.) for instructions on how to set up the infrastructure.

Once the infrastructure is set up to enforce the chosen WLAN security scheme, use the Wireless & networks settings configure the device to match the security scheme.

The device supports the following WLAN security options:

• Open

• Wireless Equivalent Privacy (WEP)

• Wi-Fi Protected Access (WPA)/WPA2 Personal (PSK)

• WPA/WPA2/WPA3 Enterprise (EAP)

• Lightweight Extensible Authentication Protocol (LEAP) - Only available with mDNA Enterprise

Bundle upgrade.

• Protected Extensible Authentication Protocol (PEAP) - with MSCHAPV2 and GTC authentication.

• Transport Layer Security (TLS)

• Tunneled Transport Layer Security (TTLS) - with Password Authentication Protocol (PAP),

MSCHAP and MSCHAPv2 authentication

• Password (PWD)

The Status bar displays icons that indicate Wi-Fi network availability and Wi-Fi status.

NOTE: To extend the life of the battery, turn off Wi-Fi when not in use.

Configuring for a Proxy Server

A proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server and requests some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client.

It is important for enterprise customers to be able to set up secure computing environments within their companies, making proxy configuration essential. Proxy configuration acts as a security barrier ensuring that the proxy server monitors all traffic between the Internet and the intranet. This is normally an integral part of security enforcement in corporate firewalls within intranets.

Bluetooth

Bluetooth devices can communicate without wires, using frequency-hopping spread spectrum (FHSS) radio frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band (802.15.1). Bluetooth wireless technology is specifically designed for short-range (10 m (32.8 ft)) communication and low power consumption.

Devices with Bluetooth capabilities can exchange information (for example, files, appointments, and tasks) with other Bluetooth enabled devices such as printers, access points, and other mobile devices.

The device supports Bluetooth Low Energy. Bluetooth Low Energy is targeted at applications in the healthcare, fitness, security, and home entertainment industries. It provides reduced power consumption and cost while maintaining standard Bluetooth range.

Adaptive Frequency Hopping

Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work. There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and discoveries during critical 802.11b communications. AFH for Bluetooth consists of four main sections:

• Channel Classification - A method of detecting an interference on a channel-by-channel basis, or pre-defined channel mask.

• Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.

• Hop Sequence Modification - Avoids interference by selectively reducing the number of hopping channels.

• Channel Maintenance - A method for periodically re-evaluating the channels.

When AFH is enabled, the Bluetooth radio “hops around” (instead of through) the 802.11b high-rate channels. AFH coexistence allows enterprise devices to operate in any infrastructure.

The Bluetooth radio in this device operates as a Class 2 device power class. The maximum output power is 2.5 mW and the expected range is 10 m (32.8 ft). A definition of ranges based on power class is difficult to obtain due to power and device differences, and whether in open space or closed office space.

NOTE: It is not recommended to perform Bluetooth wireless technology inquiry when high rate 802.11b operation is required.

Security

The current Bluetooth specification defines security at the link level. Application-level security is not specified. This allows application developers to define security mechanisms tailored to their specific need.

Link-level security occurs between devices, not users, while application-level security can be implemented on a per-user basis. The Bluetooth specification defines security algorithms and procedures required to authenticate devices, and if needed, encrypt the data flowing on the link between the devices. Device authentication is a mandatory feature of Bluetooth while link encryption is optional.

Pairing of Bluetooth devices is accomplished by creating an initialization key used to authenticate the devices and create a link key for them. Entering a common personal identification number (PIN) in the devices being paired generates the initialization key. The PIN is never sent over the air. By default, the

Bluetooth stack responds with no key when a key is requested (it is up to user to respond to the key request event). Authentication of Bluetooth devices is based-upon a challenge-response transaction.

Bluetooth allows for a PIN or passkey used to create other 128-bit keys used for security and encryption.

The encryption key is derived from the link key used to authenticate the pairing devices. Also worthy of note is the limited range and fast frequency hopping of the Bluetooth radios that makes long-distance eavesdropping difficult.

Recommendations are:

• Perform pairing in a secure environment

• Keep PIN codes private and do not store the PIN codes in the device

• Implement application-level security.

Bluetooth Profiles

Table 13 Bluetooth Profiles

Profile

Service Discovery Protocol

(SDP)

Serial Port Profile (SPP)

Object Push Profile (OPP)

Description

Handles the search for known and specific services as well as general services.

Allows use of RFCOMM protocol to emulate serial cable connection between two Bluetooth peer devices. For example, connecting the device to a printer.

Allows the device to push and pull objects to and from a push server.

Human Interface Device Profile

(HID)

Out of Band (OOB)

Allows Bluetooth keyboards, pointing devices, gaming devices and remote monitoring devices to connect to the device.

Allows exchange of information used in the pairing process. Pairing is completed using the Bluetooth radio, but requires information from the OOB mechanism. Using OOB with NFC enables pairing when devices simply get close, rather than requiring a lengthy discovery process.

Generic Attribute Profile (GATT) Provides profile discovery and description services for Bluetooth

Low Energy protocol. It defines how attributes are grouped together into sets to form services.

Generic Access Profile (GAP)

OBject EXchange (OBEX)

Use for device discovery and authentication.

Facilitates the exchange of binary objects between devices.

Bluetooth Power States

The Bluetooth radio is off by default.

• Suspend - When the device goes into suspend mode, the Bluetooth radio stays on.

• Airplane Mode - When the device is placed in Airplane Mode, the Bluetooth radio turns off. When

Airplane mode is disabled, the Bluetooth radio returns to the prior state. When in Airplane Mode, the

Bluetooth radio can be turned back on if desired.

Bluetooth Radio Power

Turn off the Bluetooth radio to save power or if entering an area with radio restrictions (for example, an airplane). When the radio is off, other Bluetooth devices cannot see or connect to the device. Turn on the

Bluetooth radio to exchange information with other Bluetooth devices (within range). Communicate only with Bluetooth radios in close proximity.

NOTE: To achieve the best battery life, turn off radios when not in use.
