Mitel 1000 Owner's Manual page 132

The number of valid wireless network frequencies varies from
country to country and you need to identify which country you are
operating the Mitel 1000 in to ensure that your network will transmit
on the correct frequency. The setting for the USA is the default
setting so you do not need to change it.
2. From the Country drop-down list, select the appropriate
country. Click on the Confirm Changes> button to apply
configuration changes and move on to the next page in the
wizard sequence, which allows you to Select your Wireless
Network Type.
Select your Wireless Network Type
The following page allows you to select the Institute of Electrical and
Electronics Engineers (IEEE) specification supported by your
network:
Each specification transmits at a certain speed (measured in Mbits
per second) over a specific frequency. The frequency indicates the
range at which wireless traffic can be transmitted or received
between the Mitel 1000 and the wireless PC(s).
Supported specifications are:
802.11B only – provides slower rates at a longer range than
802.11G (11 Mbps in the 2.4 GHz band)
802.11G only – provides faster rates at a shorter range than
802.11B (20+ Mbps in the 2.4 GHz band)
802.11B/G – supports both of the above specifications, but 802.11G
rates will be slower than they are in a G-only network
To select a network type, click on a single radio button.
Click on the Confirm Changes> button to apply the configuration
changes.
