    1515M2M cellular modems operate as a point-to-point serial device. Typically they are used as IP network interfaces by initiating a connection to a cellular carrier using standard AT modem commands then running {{{pppd}}} which performs CHAP authentication and implements the PPP protocol. The {{{pppd}}} daemon uses the {{{chat}}} application for AT command scripts and creates a network interface once authentication succeeds. Some devices expose more than one serial interface for things like AT commands, proprietary API's, NMEA data from optional GPS etc can be used while the network is connected.

     38It is difficult to suggest modems because of pin signal and voltage conflicts caused by modem manufacturers listed [#conflicts here]

     40However, the following modems can be recommended:
     41 * [#ublox U-Blox Toby L2] - 4G LTE CAT4 (GW17046)
     42 * [http://www.gateworks.com/product/item/gw16126-mini-pcie-modem-bluetooth-radio Gateworks GW16126/GW16132] - LTE CAT M1

     44== 5G Modems
     45
     465G is a new and improved standard that increases the bandwidth for modems.
     47
     48There are 2 frequency ranges:
     49 1. FR1 Frequency Range 1, Utilizes a lot of what 4G was using.
     50 2. FR2 Frequency Range 2, Shorter Range but Higher Bandwidth. Millimeter waves (mmWave).
     51
     52Read more about the frequency ranges [https://en.wikipedia.org/wiki/5G_NR_frequency_bands here]
     53
     54Many 5G cards are in the M.2 form factor and a size of 3052 (30mm wide by 52mm long).
     55
     56Some of the common 5G modems that could be used on Gateworks Industrial SBCs:
     57 * Telit FN980/FN980m (3052)
     58 * Quectel RM500Q (3052)
     59 * Sierra Wireless EM9190 (3052)
     60
     61 * Note, many of these modems are very expensive ($250-500) and they are not readily available.
     62 * Note, many of these modems are M.2, which requires an adapter if inserting in a Mini-PCIe slot. Gateworks makes a M.2 adapter for 3042 size M.2 cards. [https://www.gateworks.com/products/mini-pcie-expansion-cards/gw1614x-mini-pcie-to-m2-adapter-card/ Link Here]

    5287The Cellular Carrier dictates if your plan provides 'mobile termination' (the ability to accept connections from the Internet) and the IP address provisioning (IP class, static vs dynamic, IP range). For GSM Carriers this is based on the APN. Check with the specific carrier for different options and costs.
