For example, the link budget for a pair of Wi.232 modules in wideband mode at the maximum
data rate and using 2dBi dipole antennas would be:
+13dBm + 2dB – (-102dBm) + 2dB = 119dB
A link budget of 119dB should easily yield a range of ¼ mile or more outdoors. If the environment
is open and the antennas are 8 to 10 feet off of the ground, the range could be a mile. Indoors,
this link budget should yield a range of several hundred feet.
This is a well-balanced link budget. More than 10dB of the budget is achieved through transmit
power, which will allow good performance indoors in the presence of multi-path while keeping the
overall operating current low, making the module suitable for primary battery powered
applications such as RFID and automated meter reading.
