For example, it supports NMEA-compliant GPS over Wi-Fi, enabling compatible Wi-Fi devices to use its GPS signal for positioning services. The MiFi 4620L offers a lot of other features for a tiny device. To avoid this, you can use the Web interface to limit the maximum connected number of devices to any number less than 10. Obviously the more devices connected to the router, the slower the performance gets, especially when all of those devices are involved in network activities. Speaking of the local network, the router supports Wireless-N, offering a top speed of up to 150Mbps, which is fast enough for light data sharing between connected devices. The router supports up to 10 Wi-Fi clients when it's connected to a 4G network when connected to a 3G network, only 5 clients can access the Internet at the same time, with the rest being part of the Wi-Fi local network only. All you have to do is turn it on and hook Wi-Fi devices to the network with the provided information and you are set. This same information is also printed on the back of one of the battery bay covers and is what you need to use the device. When the cover is removed, you'll find the default Wi-Fi network's name and its password. The router comes with a choice of two bottom covers to accommodate the different thickness of the two batteries. To access the router's battery bay, you lift up the bottom cover. In this case the router can work as a modem and a router at the same time. You can use its Web interface to change the settings so that it also works as a tethered USB modem. When connected to a computer, by default, the router only charges its battery by drawing juice from the USB port. On the other side are an external antenna port and a standard Micro-USB port for charging via a power adapter (included) and connecting the router to a computer via a USB cable (not included). I found that there's no way to change this with the MiFi 4620L, so make sure you don't leave it somewhere out of reach, such as in the trunk of the car. Other routers, such as the Clear Spot 4G Apollo, will wake up by themselves when there's a connection request. Unfortunately, pressing the power button is the only way to wake it up. By default, the router automatically goes in to sleep mode when idle for 30 minutes. To turn it off, you'll need to press and hold it for a few seconds. On one side, the router has a power button that you press once to turn it on or wake it up. This is a huge improvement over the Samsung, which doesn't even have a battery gauge. There are also navigation buttons with which to access even more information via the tiny screen. On top the router has a small OLED screen that shows a lot of information, such as a battery gauge, the number of connected Wi-Fi clients, cellular signal strength, and so on. Note that this extra battery might not be available for purchase at all Verizon stores. But even then, it's still quite compact, fitting right into any pocket. The new router comes with an extra 3,000mAh (double-capacity) battery as an option, which will increase its thickness and weight slightly when used. Measuring 3.76 inches by 2.36 inches by 0.53 inch, and weighing just 3.2 ounces, the MiFi 4620L is about the same size as the SCH-LC11. Those who want to pay less for an unlimited data plan with the tradeoff of not having 3G network access should also check out the Clear Spot Voyager. That said, if you're a business user who needs a mobile router to supply a fast Internet connection while being on the go for an extended amount of time, the MiFi 4620L for now is one of the best choices.
