WLAN IP Telephony Configuration

Overview

A Wireless LAN (WLAN) refers to a computer Local Area Network that has

wireless components. It is also referred to as WiFi (Wireless Fidelity) and is a

standard that allows computer devices to connect to a network literally without

wires. WLAN IP Telephony is the ability to send voice packets across the

existing Wireless LAN Computer network, so it is sharing the same bandwidth

and connections as the Data Traffic. WLAN IP Telephony is a wireless

mobility solution which uses the 802.11b wireless platform.

The Wireless Local Area Network Handsets 2210, 2211 2212 operate over an

802.11b wireless Ethernet LAN providing users a wireless Voice over IP

(VoIP) solution.

To be able to connect to the Business Communications Manager (BCM), the

WLAN IP Telephony Handsets must be supplied with the IP Address of the

WLAN IP Telephony Manager 2245 and, optionally, a Trivial File Transfer

Protocol (TFTP) Server. The WLAN Handsets accept IP Address

configuration parameters either from manual configuration or from a Dynamic

Host Configuration Protocol (DHCP) Server. DHCP automatic discovery mode

provides the WLAN IP Telephony Manager 2245 and TFTP Server IP

addresses to the WLAN Handsets. The BCM can be the DHCP Server, or a

separate DHCP Server can be provided in the network.

The 802.11b protocol provides no mechanism for differentiating audio packets

from data packets. The WLAN IP Telephony Manager 2245 provides a Quality

of Service (QOS) mechanism that is implemented in the WLAN Handsets and

the Access Points (APs) to enhance voice quality over the wireless network.

The WLAN IP Telephony Manager 2245 gives preference to voice packets

over data packets on the wireless medium, increasing the probability that all

voice packets are transmitted efficiently and with minimum or no delay.

The WLAN IP Telephony Handsets 2210/2211/2212 use the TFTP Server to

update the wireless telephone firmware over the 802.11b WLAN.
