HELIOS's Repeater is to provide radio coverage in a flexible and efficient way. Among the things with reference to the design it can be difficult to spread coverage all the way into side isles, narrow hallways, and several statuses, combined with different building materials. Moreover, if there are many people constantly moving, for instance in shopping malls, and the demand for coverage varies from one spot to another as well as during the day and during the week, satisfying the growing demand for capacity becomes a challenge. The same status can be occurred in some villa group, Subway, Speedway, etc. So the repeater can gives you the optimal solution.

Application: In-building, Subway stations, Basement, Tunnels, Shopping malls, Speedway, Underground parking etc.

HELIOS's Wireless repeater system consists of two repeaters: Donor and Remote. Donor which is located within BTS cell site converts RF signal from the BTS and transmits it to Remote. This system is idealistic for the areas which don't allow fiber optic or coaxial cable such as island or near highway. It costs a little higher than other systems but it is worth it because it has wide range of installation location.

Features:

1. Improved system noise figure and sensitivity, provides wider coverage
2. High out band rejection, excellent intermodulation and spurious emissions
3. High gain linear power amplifier technique, with reliable performance
4. Easy to expand and maintain
5. Lightning proof and high-voltage-proof
6. Compact design, water-resistant, weather-proof and antisepticise
7. Applicable to large coverage area such as highway, town and tunnel etc.
