Recommendation for GPRS/3G modules

Novice

I am in the process of designing a custom hardware that will include a GPRS/3G module for M2M communication. My key requirements are as follows:

 

1 - Low power consumption (with a good selection of sleep modes, if possible)

2 - Small size (about 50 mm x 35 mm or less).

3 - Cost in the range of $15-$20 in volumes of 1000.

4 - Module should have a connector option rather than soldering.

5 - Should not need an external antenna.

6 - Ideally, a development kit should be available.

 

If anyone can provide assistance and advice on the above, it will be gratefully received.

 

Regards...

    I have been looking into the available modules and Cinterion and Telit modules seem to fit the bill in case any other readers are have a similar problem to mine. I have also looked into Huawei modules but I was not impressed with the service offered by the distributor in my location unfortunately. I therefore gave it up altogether. If one cannot trust the reliability of a distributor's service at the information gathering stage, I don't think it's worth risking a project with that distributor and vendor at all.

     

    Telit modules are slightly cheaper than Cinterion modules. However, I found out that for mass deployments, Cinterion modules seem to be superior. Out of 100,000 units deployed on a few projects, none of the modules have been returned to the vendor so far.

     

    Both vendors provide a good support during the design phase of your M2M project as well, which is really useful if you are planning to develop your own hardware like myself.

     

    In terms of size, Telit is slightly better than Cinterion but this difference is negligible from what I have discovered.

     

    I will add further information as ı go along for the benefit of other readers.

    Hi,

     

    I know your post is a bit old and maybe you have already decided on the module that you are going to use in your M2M design. Just wondering which 3G module you found that met your price requirements of 15 to 20$.
