Mail_huawei_supplier.txt
Hi,
We are going to require large quantity of 3G modem and we
are looking for establishing a trust relationship with a single supplier.
Our hard requirements are:
-Modems must implement standard Huawei AT command interface.
-It must be possible to place voice calls and send SMSs.
-Modems should be unlocked.
Other criteria of choice:
- The modem does not corrupt special character (like 'é' ) when reading writing
contact to SIM memory (via AT command AT+CPBR/AT+CPBW ) .
- The modem does not suffer from so called "doubletalk" problem.
situation when two people talk at the same time, causing overlapping audio signals.
- The modem receives well the GSM signal.
- It is possible to add an external antenna.
Which model (e173u, e303, e367, e173, e372, e369 or e2010) would you be able to
supply in large quantity ( ~1000 pieces for the upcoming year, probably more down the road )?
Could you provide us with samples of the models you think could best match our requirements so we can perform some testing with our solution.
Kind regards
