The Frequency Translating Concept provides:

• High output powers (20W), which is comparable to

Macro Base Stations

• Reduced site deployment costs through low isolation

requirements

• Quick & easy site acquisition since there is no need for

line-of-sight between base station and repeater

Due to the increased isolation requirement in EDGE environments,

the Frequency Translating technology plays an even larger role as a

cost-effective alternative to base stations as well as to conventional

repeaters.

Avitec’s repeaters are monitored by an advanced and user-friendly

supervision system that leads to less outage time and thereby to a

greater revenue.

The CSFT1822 consists of 2 units, a Donor Unit at the BTS site and a Remote Unit at the repeater site. The repeater can be congured to handle up to 2 GSM/EDGE carri-ers.

Quick deployment and cost-effec-tive coverage in rural areas, using the CSFT1822.
