GSM/3G Repeaters

Mobile phone conversations in buildings are often difficult to carry on, if not impossible. This is due to the signal attenuation through walls, window panes, ceilings (underground). The problems occur in stores, tunnels, underground car parks, petrol stations, airport halls, hotels. A similar situation can be found in buildings located on the border range of base stations (recreational areas, mountains etc).

Taking into account the type of equipment for the assessment of conformity with the essential requirements (compliance with Article 3.2 of the Directive 1999/5/EC) on the effective use of radio spectrum, the following test program has been established...

The EU has increased the requirements for GSM repeaters. They relate to both the width of the transmitted bandwidth (EGSM) and out-of-band emission. The newly introduced SIGNAL repeaters (model numbers: 305, 505 and 1205) meet the requirements. Each of these models has also been equipped with adjustable input attenuator and AGC function.
