Overview

When WMM is used, all voice traffic originating from the wireless handset is
assigned the WMM Voice Access Category, making it the highest priority
application. If the wireless network supports WMM, the handsets enable
WMM support automatically; otherwise, SpectraLink Voice Prioritization
(SVP) is used.

Wired Equivalent Privacy

The handsets support Wired Equivalent Privacy (WEP) as defined by the
802.11a, b, and g specification. Nortel offers the product with both 40-bit
and 128-bit encryption. WEP increases the security of the wireless LAN to a
level similar to a wired Ethernet LAN.

Wi-Fi Protected Access

The handsets support Wi-Fi Protected Access (WPA) using preshared key
(PSK), as defined by the 802.11i specification. WPA increases the security
of the wireless LAN, using key encryption, key rotation, authentication and
message integrity checking.

Wi-Fi Protected Access2

The handsets support Wi-Fi Protected Access2 (WPA2) using preshared
key (PSK) and Advanced Encryption Standard (AES), as defined by the
802.11i specification. WPA2 increases the security of the wireless LAN,
using key encryption, key rotation, data encryption, authentication, and
message integrity checking.

Virtual Private Network

The WLAN Handset 2212 supports Virtual Private Network (VPN) security.
VPN security provides a secure tunnel for the transfer of unencrypted
information. A two-phase approach is used to negotiate the tunnel, with
Phase 1 protecting Phase 2. Phase 1 uses preshared keys, Diffie-Hellman
group, hashing, and encryption. Phase 2 uses hashing and encryption.
Both phases have limited, configurable lifetimes.

Push-to-talk feature

With the Push-to-talk (PTT) feature, the WLAN Handset 2211 and the
WLAN Handset 6140 can operate in a PTT group-broadcast mode like a
two-way radio, in addition to the standard telephone operation.

For more information, see WLAN Handsets Fundamentals (NN43001-505).

Text-messaging feature

All WLAN handsets support text messaging applications through the WLAN
Application Gateway 2246. The application server communicates to the
WLAN Application Gateway 2246 through a proprietary Open Application
