Measuring MAHO

up a call (Test Set must be in Connect

mode).

2 Select Meas from the Data / Meas

field.

3 Select the field that has appeared be

low Data / Meas.

4 Select MAHO from the list of choices.

channel are reported, as well as the

RSSI of the designated neighbor chan

nels.

MAHO (Mobile Assisted HandOff) is actu-

ally a measurement, not a handoff. The re-

ported results are used by a base station to

select the channel for the handoff.

The mobile performs the measurements, and

them reports the results back to the base sta-

tion. The mobile measures the RSSI of

neighboring channels, as instructed by the

base station. It also measures and reports

the RSSI and BER of the current channel.
