Modem: Difference between revisions

Revision as of 19:14, 22 October 2016

The Modem will be an PLS8-E(EU Versions) ([1],Features for both Versions, Datasheet) or PLS8-US(US Versions). It provides GSM, LTE and GPS. SMS and Voice is supported and tested, however it will fallback to 2G for Voice on most Networks. There's an CPU-GPIO controlled FET switch to disconnect the whole Modem from Power so you don't have to rely on the Closed-Source Modem Firmware. Also there's an Current Sensor to detect if the Modem is doing unwanted Things. [2]

Antenna

The Antenova A10340 as seen here [3]is listed with "Antennas Calvus SMD GSM850/ 900/1800/1900/WCDMA"

Carrier Compatibility

Main article: Carrier Compatibility

US

Look for a GSM network, like Tmobile or AT&T. (Verizon and Sprint use CDMA networks, which are incompatible with the Pyra modem.)

US MVNOs

There are smaller companies which use the Tmobile and AT&T networks (i.e. Virtual operators), but you'll have to look through for the GSM carriers with a BYOD policy.

Some that may allow use of a Pyra (none yet confirmed) include:

Cricket Wireless
Ting
MetroPCS
Simple Mobile

Australia

Australia requires the European Pyra Modem. See this Whirlpool Forum post for more details.

Europe

Pretty much everybody???

-<strike> GSM/LTE is most prevalent, and would mean only one chip in all Pyras. For reference these are the networks and frequencies used in [https://en.wikipedia.org/wiki/List_of_mobile_network_operators_of_Europe Europe] and [https://en.wikipedia.org/wiki/List_of_United_States_wireless_communications_service_providers The US]
-Another variable is price. A 3g modem is cheaper than a 4g one. But they are pin-compatible, which means a decision can be made based on demand. It is also possible to upgrade to 4G by moving to those in production at a later stage. </strike>
