The Netgear 4G LTE modems cover three different models which may be useful to mobile internet users who are looking for an Ethernet LAN port - but not Wi-Fi connectivity.

There are three versions of the Netgear LTE Modem, with only minor differences between them:

4G LTE Modem (Model LB1120) - The basic model. List price $119.99.
4G LTE Modem with POE (Model LB1121) - The only difference with this model is that it can be powered over POE (power over Ethernet) as well as via the power jack. If you have a device that has a spare POE port (like a WiFiRagner GoAC), this can let you avoid needing a power supply. List price $139.99.
4G LTE Modem with Dual Ethernet Ports (Model LB2120) - This model lacks the ability to be powered over POE, but adds an ethernet WAN port. This second ethernet port is designed to let the LTE Modem sit inline between a traditional DSL or Cable Modem and a home or office router. If the wired internet goes down, the wireless modem can then take over. This is handy for providing backup service to a home or office, but not useful for most mobile installations. List price $159.99.

Other than by comparing the back panel, all three models look identical.

The LTE modem chipset is the same for each variant.

Netgear 4G LTE modems are not sold directly by AT&T, so the come unlocked.

These devices can also be used on T-Mobile's network thanks to Band 12 support - but the devices do not support T-Mobile's newer Band 71. There is limited Verizon support - users would be better off with a dedicated Verizon device.

Compared to other AT&T devices on the market, these LTE modems have inferior specifications.
