Poor reception at home? Consider these three options:

• WiFi/Cellular combination – you need 1) a WiFi-enabled handset ( Nokia’s 6086, Samsung’s t409, and RIM’s 8320), 2) WiFi router, 3) subscription with T-Mobile HotSpot@Home and 4) a broadband connection. Calls to and from your WiFi-enabled handset will be handled by the WiFi router which, in turn is, connected to internet through your broadband connection. When you’re at home, it’s VoIP. But when you go outside of your house, your calls will be handled through the familiar cellular network of T-Mobile.
• Femtocells (or in-home mini cell tower) – example is Sprint’s Airave which works with all Sprint phones and transmit calls through the same broadband connection. Calls originating inside the Airave coverage area will be transferred to Sprint’s cellular network once you leave the coverage area. However, calls made outside of Airave coverage cannot be transferred to the Airave device even though you may be within the coverage area. Text messaging and voicemail works fine, and Airave supports up to three simultaneous calls.
• Signal Booster – a cellular signal booster such as those from Wi-Ex and Wilson Electronics might be a better alternative. For $400 you can buy a dual-band amplifier and antenna system that works with both CDMA providers (such as Sprint and Verizon) and GSM carriers (AT&T and T-Mobile). Cell boosters require an antenna in a spot (often outdoors) that has good reception–the amplifier can boost indoor signal strength only to the level the outdoor antenna receives. But they work with any normal handset, and can even boost 3G data access.
