For the development modem, I?ve chosen a simple SIMCOM SIM5360 3G modem. Just something to get us started with. The board we are making will also support a SIM7100 4G modem chip as well. Most recent SIMCOM modules are compatible.<br>
<br>
Specifications for the modem are here:<br>
<br>
<a href="http://simcomm2m.com/En/module/detail.aspx?id=82" rel="noreferrer" target="_blank">http://simcomm2m.com/En/module/detail.aspx?id=82</a> <<a href="http://simcomm2m.com/En/module/detail.aspx?id=82" rel="noreferrer" target="_blank">http://simcomm2m.com/En/module/detail.aspx?id=82</a>><br>
<br>
There are three models available:<br>
<br>
SIM5360A<br>
Dual-Band UMTS/HSPA+ 850/1900MHz<br>
<br>
SIM5360(J)E<br>
Dual-Band UMTS/HSPA+ 900/2100MHz<br>
<br>
SIM5360J(D)<br>
Dual-Band UMTS/HSPA+ 800(850)/2100MHz<br>
<br>
The 2G frequencies are all quad-band (GSM/GPRS/EDGE 850/900/1800/1900MHz). The only difference is the dual-band UMTS/HSPA+ frequencies 850/1900MHz, 900/2100MHz, or 800(850)/2100MHz.<br>
<br>
Hong Kong uses:<br>

<br>
Name Interface<br>
B1 (2100) <<a href="https://www.frequencycheck.com/bands/umts-hspa-band-1-2100" rel="noreferrer" target="_blank">https://www.frequencycheck.com/bands/umts-hspa-band-1-2100</a>> UMTS <<a href="https://www.frequencycheck.com/interfaces/umts-hspa" rel="noreferrer" target="_blank">https://www.frequencycheck.com/interfaces/umts-hspa</a>><br>
B8 (900 GSM) <<a href="https://www.frequencycheck.com/bands/umts-hspa-band-8-900-gsm" rel="noreferrer" target="_blank">https://www.frequencycheck.com/bands/umts-hspa-band-8-900-gsm</a>> UMTS <<a href="https://www.frequencycheck.com/interfaces/umts-hspa" rel="noreferrer" target="_blank">https://www.frequencycheck.com/interfaces/umts-hspa</a>><br>
So, the first development modem I am getting is SIM5360(J)E.<br>
<br>
For other developers, who will be wanting early OVMS v3 modules, where do you live, what cellular carrier do you use, and what frequencies do you use?<br>
<br>
Regards, Mark.<br>
