LTE Networks

How do I obtain and interpret SINR values for LTE networks?
You can use the AT*CELLINFO? command to obtain an SINR (Signal to
Interference plus Noise Ratio) value. (See
The values vary depending on the network characteristics and the AirLink
gateway, but in general, a positive value provides usable throughput. The
following table provides guidelines for interpreting SINR values.
SINR Value
<
0 Poor
0 to 5 Fair
6 to 10 Good
> 10 Excellent
If the SINR value indicates poor throughput:
• Move the antenna away from noisy equipment.
• Move closer to the nearest cell tower line of sight, or further away from the
interfering cell tower.

SIM Card is Blocked

My SIM card has a PIN number. I've entered the wrong PIN several
times and now the SIM card is blocked.
AirLink products do not support Personal Unlocking Key (PUK) entry. However, if
you need to unblock the SIM card:
1. Contact your Mobile Network Operator to obtain the PUK.
2. Remove the SIM card from the AirLink gateway and insert it in a cell phone
that accommodates a MiniSIM (2FF) card.
3. Enter the PUK to unblock the SIM card and then return the SIM card to the
AirLink gateway.
