[Ovmsdev] OVMS v3 Pre-Launch Announcement

[Mark Webb-Johnson]

I got a number of eMails regarding 4G support, and sent this as a reply:




Not wanting to fall into the same trap as OVMS v2, where the entire board is designed around the modem module, we designed the OVMS v3 system to have optional pluggable modem boards. We want to be able to exchange modem board, for newer technology, without having to change the entire system. We also designed the modem circuit board itself to support different modem modules, and our current modem board design supports both SIM5360 (3G) and SIM7100 (4G) modules, on the same board layout.

However, today, the SIM5360 modules are almost six times the price of our old SIM900 ones, and the SIM7100 is almost twice that again. So, we can support 4G modems - just too expensive at the moment to be worthwhile. I am also concerned because 4G LTE NB-IoT is coming soon, and that seems a much better match for what we require (SIM7000 module).

Overall, we decided to stay with 3G for the moment, and see what happens with NB-IoT later this year. We will then either release SIM7000 or SIM7100 modem option.

Hope that helps, and makes sense.

Regards, Mark.

> The antenna and vehicle connectors for OVMS v3 are the same as for OVMS v2, and existing cables/antennas can generally be re-used for OVMS v3. Note, however, that the frequency ranges supported by individual 3G networks may be different than 2G, so may benefit from an antenna specifically designed for the 3G frequency ranges used.
