There are certain advantages in having a cellular phone as a landline replacement, such as having to pay for only one service. But because not all cell carriers are reliable enough to provide drop-free calls indoors, a home cellular-range extender is needed, like the Sprint Airave. The Airave looks like a glossy white router. It connects to an existing home router via Ethernet cable. To prevent users from bypassing roaming charges, the reviewer noted that the device must first authenticate its location using an internal GPS. However, the first time the GPS tries to home in on the device took more than an hour. Once working, the Airave works just as advertised. Signal strength jumped from one bar to six and the reception never wavered. The reviewer noted that the range didn’t come close to the 5,000 feet rating, though. On top of the charge for the Sprint Airave, Sprint also charges $4.99 a month just to use it - something which the reviewer found to be unjust. On the other hand, if you can afford all the fees that come with it, the Sprint Airave is a sure-fire way to boost your cellular range in your home.
