Overview
Nortel Wlan Handsets 2210, 2211 and 2212 are mobile phones for workplaces with Nortel Communication Servers. Wlan Handsets reside on the wireless lan with other wireless devices using direct sequence spread spectrum (Dsss) radio technology. They operate over an 80211b wireless ethernet providing users a wireless voice over IP (VoIP) telephony extension, sending and receiving packets at up to 11 Mbps Quality of service on the wireless for IP Telephony is provided through the Wlan Telephony Manager 2245The Wlan application Gateway 2246 is an open application interface (oaI), which enables third-party software applications to communicate with the nortel Wlan Handsets
By seamlessly integrating with the infrastructure IP telephony system, wireless telephone users are provided with high-quality mobile voice communications throughout the workplaceThe wireless telephone gives users the freedom to roam throughout the workplace while providing all the features and functionality of an IP desk phoneThe Wlan IP Telephony Handset is one of the components of the nortel Wlan IP Telephony solution

Features and Benefits
Nortel WLAN Handset 2210
Alightweight, durable handset, specifically designed for mobile workplace use within a facility using supported nortel IP telephony call servers and 80211b access points (aPs) in a wireless lan This compact handset offers features and accessories that address the needs of a variety of businesses at an attractive price.The Wlan Handset can receive calls directly, receive transferred calls, transfer calls to other extensions and make outside and long distance calls (subject to the restrictions applied in the facility)The Wlan Handset is solely for use on-premise; they are not cellular or satellite phones.

Nortel WLAN IP Telephony Manager 2245
A network appliance that works with the aP to provide quality of service (Qos) on the wireless lan UnIstim is a proprietary protocol developed by for communication between a IP phone and a call serverall UnIstim packets to and from the Wlan Handsets 2210, 2211 and 2212 pass through the IP Telephony Manager 2245 and are encapsulated for prioritization as they are routed to and from the supported nortel IP telephony solution
The Wlan IP Telephony Manager 2245 is required for Qos because the current Ieee 802.11b standard provides no mechanism for differentiating audio packets from data packets.The new standard being developed (80211e) will provide all the functionality of the nortel IP Telephony Manager 2245, thus ensuring high-quality voice in a mixed client environment.once 80211e is ratified, nortel will adopt the new specification.
Nortel Application Gateway 2246
an oaI that enables third-party software applications to communicate with nortel Wlan Handsets 2210 and 2211, is a messaging protocol interface that is open to any developer.Many applications are currently integrated with and others are continuously being developed to meet specific vertical market needs. Nortel offers a developer’s package that provides the software necessary to easily integrate and test applications.
