Verizon Wireless 4G LTE Mobile Hotspot MiFi 4510L

Novatel's V4G LTE Mobile Hotspot MiFi 4510L for Verizon Wireless ($269.99) is a lightning-fast way to get up to multiple Wi-Fi devices online, even when there's no wireless network in sight. With the 4510L, I was able to achieve double the download speeds and ten times the upload speeds, on average, than I get with my home Internet connection—which never struck me as particularly slow in the first place. While the 4510L isn't significantly speedier than Verizon's Samsung 4G LTE Mobile Hotspot SCH-LC11 ($269.99, 3.5 stars), it has a much better battery and signal strength indicator, and connects more reliably, making it our latest Editors' Choice hotspot.

Physical Design and Data Plans
Measuring 2.4 by 3.7 by .5 inches (HWD) and weighing 3 ounces, the 4510L is little bulkier than the LC11, but not distractingly so. And unlike the LC11, the 4510L has an excellent e-ink external status display that clearly shows signal strength and battery life, as well as how many devices are connected to the hotspot using dots to represent each one. An easy-to-understand, multicolor LED status light is located on one side of the device to indicate connection status. There's a port for an external antenna on the other side of the hotspot, but there's no MicroSD card slot, so you can't use a memory card as a shared drive between connected devices.

You can connect the hotpot to a laptop via the included microUSB cable, but this will only charge the device; the hotspot won't transmit while it's connected via USB. Conveniently, you can connect the LC11 via USB and it will still transmit Wi-Fi data at the same time, so this is something to consider if you plan to charge your device via USB while using it. The 4510L can also be charged using the included microUSB wall charger, however, and it can transmit wireless data this way.

Though Verizon's 4G LTE network is currently the fastest around, the carrier doesn't offer an unlimited or large-capacity data plan. You can get 5GB per month for $50 or 10GB per month for $80, plus $10 per additional GB. This means you likely won't be able to use 4G to replace your current home Internet connection. If you download lots of movies or television, for instance, chances are you'll reach your monthly data cap sooner rather than later. To compare, Sprint's 4G WiMAX network has shown considerably slower speeds in our tests, but least there's no cap on the amount of data you can use per month.
