Info:

Compass 885/88x have a microSDHC reader capable of reading microSD cards with a capacity of up to 32 GB.
However, given the current microSDHC cards available in the market, we have successfully tested 4 GB microSDHC – Class 4 cards from manufactures such as SanDisk, PQI and Apacer.

Verifying the signal strength
To display the signal strength (RSSI), hold the Option key down and click the WWAN icon. The signal strength is shown in the first line.

RSSI Guidelines
-50 to -80 dBm: Very good
-80 to -90 dBm: Good
-90 to -100 dBm: Low

You may require an external antenna if the signal is low.

Feature Modem

The TRU-Flow solution solves the data throughput problem during simultaneous UL and DL transfers regardless of application,
and minimizes Round-Trip-Time (RTT). It continually monitors IP traffic, RTT, and data throughputs, implementing a patent-pending algorithm to ensure the fastest possible throughput. The TRU-Flow solution is independent of the technology used for the WWAN connection (CDMA, UMTS, etc.), and can be added to most WWAN network devices.

When a user attempts simultaneously UL and DL data transfers, overall data throughput can be significantly reduced. The TRU-Flow solution is designed to solve this problem.

The following figures show that the DL speed more than doubled during simultaneous DL and UL transfers when using the TRU-Flow solution.
