I just posted a separate thread that has two articles on 5G cell phones via a new CBRS service. One article discusses the various cell phone chip makers and some of the bands and different modems. CBRS uses only 137 MHz in the 3.5 to 3.7 GHz band. But I think that 5G is a lot bigger than that.

[image] SteveR: CBRS Per Wikipedia that is band n48 and per the OP band n48 is supported by this modem but LOL YMMV. [image] SteveR: But I think that 5G is a lot bigger than that. Refer e.g. 5G NR frequency bands - Wikipedia

Y’all planning to bridge a private CBRS network to your SIM network? I’d be happy for single-duplex person to person or group conversations – even if it was only good for 5 miles or so. Of course, I’d be happier with hardware PTT button to support it. Aren’t there user accessible/programmable I/O…

[image] Photon: Aren’t there user accessible/programmable I/O pins on the L5? Yes e.g. using the breakout board you can probably add a button.

The 3450 MHz to 3700 Mhz band was taken away from Amateur radio operators in 2020. With CBRS, you can build and use your own hardware if you get it certified by the FCC first. But to be certified, the radio has to allow itself to be managed by a central piece of hardware that enforces an FCC accepte…

I did a search for a list of cell phones that are capable of CBRS operation. A small number of both Apple and Android cell phone models were on the list (probably early adopter models). Coincidentally (or maybe not coincidentally) they seemed to be the same models that are capable of cell phone dire…

Put a LoRa radio in instead of the modme and load up Meshcore or Meshtastic. Peer to peer messaging. Someone needs to port Meshcore or Meshtastic to the L5.

[image] SteveR: Before Purism invests much in to 5G phone development, someone at Purism needs to fully understand everything there is to know about that plan so that whatever they build is a fully featured 5G phone Bear in mind though that the current approach involves a removeable and repla…

[image] irvinewade: It is also acknowledged that choice of modem card is limited by the existence of open source drivers and adequate support and documentation from the card’s manufacturer. Other filtering factors: size and formfactor, slot keying, usb requirement and that voice is possible. …

Just curious: I’m reading and following this thread but, because I’m not expert/engineer/technician (I kindly remind you that I’m working in tourism, so a totally different field!!) I asked to AI if 5g is better than 4g about privacy and security! In my opinion it doesn’t make sense to use Librem 5 …
