3 View of the packaging Signal GSM-1205 A6785 repeater allows to amplify GSM signals inside buildings. The device is ideal for locations where the range of a cellular network allows for use of mobile phones out of buildings, but is insufficient for indoor operation. Such locations include some remote places (long distances to base stations), but more often rooms in old buildings with thick walls or in basements and cellars (e.g. pubs, coffee shops). A strong barrier can also be modern windows with panes covered with metallic layers. The SIGNAL GSM-1205 repeater is among the first devices that amplify the whole GSM+EGSM frequency range and comply with ETSI standard that is the basis for CE declaration. Distinguishing features: Support for GSM networks (GSM+EGSM) MHz; Compliance with ETSI required for this kind of devices; AGC (ALC) - automatic gain/level control; MGC - manual gain control (attenuator); Gain suitable for the coverage area; Indoor coverage area up to 1200 m 2 ; Easy installation (Plug and Play); The packaging does not contain an outdoor antenna (it should be selected depending on signal level - usually A741030, sometimes A7018 or A7028); 24-month warranty. Contents of the set: Main unit, Special bracket for mounting the device, User manual (in English), Power supply. This product can solve the problem of low signal in hotels, boardinghouses, and various buildings, allowing to use cellular phones for calls and Internet access. 3

4 Important features: Extended operating band. The GSM repeater amplifies signals of the "old" GSM band and new EGSM band that has been introduced to increase the number of operators. The total frequency range of the device covers MHz and MHz bands. ALC function. Automatic level control automatically adjusts gain of the device within range of 20 db. It will not allow to overdrive the internal amplifier in the case of input signal fluctuations. Adjustable input attenuation The built-in attenuator allows to adjust the optimum level of the input signal (attenuation 0-31 db, step 1 db). The National Institute of Telecommunications in Warsaw, Poland, confirmed the compliance of the device with ETSI standard. CE Declaration of Conformity for GSM-505 A6785 Additional information on the new repeaters is available here. Installation of the Signal GSM-1205 A6785 repeater: find a place outside building with a good GSM signal, mount the outdoor antenna (usually A741030) so that it is directed towards GSM base station, choose a location for installing the repeater somewhere inside the building to place the indoor antenna in the central part of the building/hall/room to be covered, check if the distance to the place outside is not longer than 10 m (longer distances are not recommended due to power loss), install the Signal GSM-1205 repeater in the suitable place in the hall/room (away from heaters etc., ensuring natural ventilation), be sure that the antennas are connected to the dedicated, marked sockets, connect the AC power plug to a wall outlet (230 VAC). Signal GSM-1205 A6785 repeater connects with both antennas via coaxial cables. It usually provides enough flexibility to place the device near an AC power socket. Below there is an example of using the repeater for better cellular coverage in a home 4

To evaluate the price of such a repeater, we need the necessary technical specifications: frequency range: 400 MHz to 2700 MHz. A single repeater can amplify multiple channels, also with spacing. gain:10 db to 85 db output power: dbm 5
