The house where we have mounted this MA-1000GW repeater has a total area of 180 m², consists of one floor and has brick walls without metal constructions. The other three indicators show the incoming signal level. All that leads to system restart or turn-off. If the system works correctly, ALM indicator is off it turns on only when the incoming signal is too strong, if jammers create interference or in case of short circuit on the line. The front panel of the cell phone repeater has got five indicators: PVR indicator for power supply (turns on green when the repeater works), ALM indicator for alarm. Coaxial antenna cables features N-type connectors the outdoor antenna cable gets connected to BTS port of the repeater, and the indoor antenna cable to MS port. The MA-1000GW gets plugged into 220Wt socket with the help of the 5B/3A power supply included in the set. Having mounted and adjusted both antennas, it is time to turn on the cell phone booster and test the connection quality. In our case we managed to get -60dB which is quite good taking into consideration large distance to the base station. Having achieved the best result possible, you should fix the antenna by tightening the mounting brackets. Thanks to soundtrack and signal level indicator you can easily direct the antenna towards the base station. This is a free program that permits to detect signal level that the antenna receives. We have used GSM Antenna Tool ( Myamplifiers comment - this program is available on Russian language only) which is compatible with all routers, including 3G ones, and runs on Windows via real or virtual COM port. You can do it by using a special application such as GSM Antenna Tool or MDMA. Most of the time is required to place and direct the outdoor antenna correctly. If a building has several floors, it is recommended to place the antenna on the top floor. The indoor antenna is omnidirectional and should be mounted in the center of the zone that you need to cover. You can easily change the direction of the antenna thanks to mounting brackets adjustable around the axis and vertically. The external antenna should be directed towards the nearest BS because only following this condition you will get a maximum possible signal. External antenna diagram should not interfere with the indoor antenna’s so as to prevent the system from overlapping and interference. The outdoor antenna is of directional type, so during its installation it is essential to consider how high it is mounted and where it is directed. We managed to mount the whole system within 30 minutes, taking into account even installation of a pole for an outdoor antenna on the roof. Well, as for the installation, the process takes really little time because the repeater set is ready for instant mounting as it includes every accessory that you need. But note that this parameter refers to open areas, while inside the building the coverage area will decrease significantly due to multiple obstacles. The indoor antenna gain equals 5dBi.Īccording to the technical characteristics, MA-1000GW is a dualband cell phone booster that ensures stable mobile connection on the territory up to 1 square km. The outdoor antenna works at 800-2400MHz and has 10dBi gain index. The device is shipped with the complete booster system including indoor and outdoor antennas with cables and connectors, a power supply and mounting brackets.ĭown-link freq: 935-960MHz & 2110-2170 MHzĪs you can see in the specifications the mobile booster functions in the entire GSM frequency band and in WCDMA 3G band as well. Let’s take a thorough look at the booster MA-1000GW. If you climb onto the roof, the cell phone screen shows 1 bar. The signal reception inside the building is null and the patio is also beyond the signal coverage. We have mounted the MA-1000GW in a house that is 11 km away from the BS. Actually that is a pure theory, while in practice when you move about 8-10 km away from the base station, your phone calls start to break off. We have been lucky to get a cell phone booster Nikrans MA-1000GW for testing, and here we share our impression and experience.Īs everybody knows the range of a cell phone base station (BS) is 30-35 km in direct visibility conditions, while in a densely built-up area this parameter reduced to 4-6 km. The good news is that weak network signal can be improved with the help of a special device – cell phone booster. Today we are going to talk about cell phone connection problem that usually appears when distance between the base station of a mobile operator and your location is large.
