All you need is one place in your home or office that gets one usable bar of T-Mobile 3G, 4G, or LTE coverage. Just a little bit of 3G, 4G, or LTE signal strength and our revolutionary new Cel-Fi will bring you blazing fast downloads, smooth video, surfing, and improved voice coverage. T-Mobile: 4G LTE, 4G HSPA+, and 3G dual band (AWS, 1.9GHz: 3GPP band 2 & band 4). Simply plug Cel-Fi's Mobile Phone Signal Repeater in. Cel-Fi is absolutely void of any antennas, cables, switches or configuration needs, making it totally plug and play. Since both units communicate wirelessly, you can put them in the best location in your house or office, and Cel-Fi configures itself automatically.Your communication and data are secure. Because Cel-Fi repeats T-Mobile wireless signal, it maintains all of the security protocols of the T-Mobile Wireless network. Your call or data session is never transmitted over the internet.Systems sold in the US will not have the external antenna adaptor. This is a CONSUMER device.
