Understanding LTE Modem Specifications And Selecting Cellular Devices (MiFi, Jetpacks, Routers, Phones)

Using a cellular device is the most common ways to get online for RVers and Cruisers.

There are many types of devices that can be utilized - mobile hotspots (aka Jetpacks or MiFis), smartphones or cellular embedded routers.

For more on the basics of mobile hotspots, routers, and smartphones:

Understanding the features of a specific device is almost as important as selecting the right form factor for your needs. These features can range from modem specifications, local networking capability, or options for enhancing the signal to your device.

All of these factors can combine together to determine how well a device will work for you and the actual performance you are able to get out of it.

As each of the cellular carriers continues to advance their networks, your cellular data performance will be directly impacted by how modern your device is. For those who consider mobile internet critical to their lifestyle, we generally recommend evaluating the cellular modems at least every year or two to keep current.

Cellular Features & Standards

The Netgear Nighthawk is AT&T's latest flagship LTE mobile hotspot.

An integrated cellular modem is the core of every cellular device  - it's what gets you connected to your carrier's network. Modem technology is constantly advancing.

You'll want to check the following technical details:


Most mobile hotspots are designed specifically for a primary carrier. They tend to be offered directly by the carrier for purchase and branded as such (example: The Novatel 7730L is branded and designed for Verizon, the Netgear Nighthawk for AT&T).

T-Mobile and AT&T devices tend to have a lot of cross over support for each other's networks, but you'll have to shop for carrier unlocked devices to successfully SIM swap - or convince your carrier to unlock the device. Other carrier specific devices don't tend to have enough cross over support to be worth the while.

Additionally, there are many non-carrier devices on the market that can successfully work on multiple carriers - these tend to be classified as cellular embedded routers which are different animals from mobile hotspots.

Smartphones tend to have more cross-carrier compatibility, but you still need to check their specific specs - as some are released specifically for a carrier.

Cellular Frequency Bands

What bands for LTE, 4G, 3G and 2G are supported? Check to make sure that any cellular modem you purchase supports all the current LTE bands in use by your carrier, and that it can also fall back to 3G networks when needed.
