Ranges are affected by receiver sensitivity; transmit power, free-space path loss,
antenna gain, and link margin. Actual range will vary from those stated. Non-line-
of-site applications will result in typical values less than shown above.
The Data Rate is the supported connection rate for the wireless link, the actual
data throughput for the link will be less than the stated data rates.
