Gear Diary: Cell Ranger – the answer to iPhone 3G signal woes?
Unfortunately, cell phone coverage is far from perfect. The quality of cellular service varies depending on the distance from the tower and the number of obstacles blocking line of sight. Many people experience frustrating dropped calls at home, in the office, or while traveling due to poor signal strength.
Adoption of new 3G data services promising broadband data access makes these problems even more acute. Download speeds depend very strongly on the signal strength, and newly built 3G networks contain many coverage holes. Without adequate signal, users are finding that 3G connections drop to a fraction of their advertised speeds, and packet loss problems often make data cards completely unusable.
Our solution: Cell Ranger
Our first two products have spent two years in development, and we’re very happy to finally make them available to the public. PORT and STIX are the first two products in the Cell Ranger line of boosters. Both products contain our revolutionary Cell Ranger microprocessor, which actively scans the frequency bands being used and selects the signals that need to be amplified.
During our testing and development of our products, we found that about 85-90% of reception problems are caused by weakness in the downlink signal (the signals being sent from the tower to the cell phone). The receivers used in cell phones are considerably less sensitive than those used in cell towers, so they need stronger signal in order to maintain a reliable signal. Cell Ranger PORT and STIX address this problem by amplifying the necessary cellular frequency bands to provide clearer signal for the cell phone to decode.
Cell Ranger PORT and STIX each provide 2-3 bars of extra signal within a 6 foot coverage area, and are compatible with both cell phones and 3G data cards. PORT uses a USB port for power, making it perfect for portable use at home or in the office. STIX plugs into a 12V car cigarette lighter, making it ideal for road warriors who need perfect coverage on the road.
