Nortel Networks NN43001-504 manual Wired Equivalent Privacy, Wi-Fi Protected Access

28Overview

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
