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 |
