Verifying Signal Strength

The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal strength, do the following:

1.Using the HyperTerminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CSQ. A value for the received signal strength will be returned.

2.Verify the result with the following chart:

Signal Strength Verification

Value of signal strength	Signal strength
(AT+CSQ response) (RSSI)
10 - 31	Sufficient
0 - 9	Weak or Insufficient
99	Insufficient

Verifying Network Registration

In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network. To do so, you will use the common communications program Hyperterminal.

1.Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CREG?. A value for the modem’s network registration status will be returned.

2.Verify the result with the following chart:

Network Registration Verification

Value	Network Registration Status
0, 1	Yes
0, 5	Yes
	(registered roaming)

Note: If the modem is not registered, perform the procedure for verifying signal strength to determine the strength of the received signal.
