GSM COVERAGE WITH CELL ENHANCING REPEATERS

ProductsAvitec develops and manufactures repeaters for mobile telephone and trunked radio networks. The product range covers applications for frequencies from 70 to 2200 MHz. Components for system solutions, like combiners, couplers, cables and antennas, are also available from Avitec.

Customers From the coldest parts of Canada to the hottest jung-les in VietNam Avitec’s repeaters are operating today. Avitec’s customers are found in all parts of the world where mobile phone operators and other radio based services exist. The proliferation of mobile telephones

over the last decade has increased the demand for special coverage solutions as subscribers all over the world expect coverage everywhere. In rural areas, on country roads, in motorway tunnels, railway tunnels and dozens of other places where BTS signals are too weak repeaters are often the most technically and economically viable solution.

Avitec’s high power frequency shifting repeater has performance levels on par with a BTS and can be used instead of a BTS in areas where capacity is not a vital issue. As mobile communication applications expand in the 21st Century, Avitec will continue developing

obstacles acting as barriers to communication.

ServicesAvitec’s business is based on the fact that radio signals do not penetrate solid objects and methods of relay-ing the signals through such obstacles are required. Avitec designs and manufactures repeaters and supp-lies complete system solutions for the strategic dist-ribution of radio signals. By combining repeaters with

biners, Avitec can help you extend your coverage to

and an impressive list of references makes Avitec the ideal partner to help you solve coverage problems. All the way, from system design, through site surveys, product development, to installation and site accep-tance tests, Avitec can provide the expertise, products and services you need.

Operation and maintenanceAll repeaters can be controlled and monitored via

the Avitec Repeater Maintenance Console or the Avitec Element Manager. Full alarm reporting, heart-beat meassages, all settings like frequency, gain and attenuation as well software upgrades can be handled remotely via the Avitec Elemnet Manager.

AVITEC AB, a strong partner in radio coverage solutionsAvitec specialises in providing radio communication solutions in areas that are geographically or physically problematic. As large numbers of people become increasingly dependant on mobile communications, coverage every-where is taken for granted. Many years of product development and several major turnkey projects have helped Avitec build up the expertise necessary for innovative and reliable coverage solutions.

GSM

Channel Selective 900, 1800, 1900The Channel Selective repeater provides a quick, cost effective means of extending coverage in new or existing wireless networks, providing an instant revenue generating opportunity. By working in conjunction with base

terrain, buildings tunnels.

Fiber Optic fed 900, 1800, 1900

where long distances would cause attenuation problems in coax cables. The repeater is connected to the base station via an optical Hub. The Hub con- verts the RF signal into an optical signal which is then transmitted to the

away from the base station.

Products and Applications

Frequency Translating 900, 1800, 1900The Frequency Translating repeater provides output power levels comparable to Base Stations in GSM networks. The frequency translation concept used in the repeater allows for high gain without the high antenna isolation requirements of conventional repeaters. The Frequency Translating repeater consists of 2 units, a Donor Unit
