Different Cell Structures

RBS with one omni-directional antenna

covering 360o

RBS with three antennas each covering one sector,

(120o) – longer range

120o

Depending on RBS-type we can have up to 6 sectors in a cell

Remote Electrical Tilt - RET

RET system is designed to meet the high requirements for reliability, flexibility and efficiency in remote control of tower-mounted telecommunication equipment.

Optimize network in real time, saving time and costly site visits.

Respond quickly to changing traffic needs. Experience higher tilt possibility compared to

mechanical tilt. Reduces human error with accurate mechanical

control. No specialized manpower or equipment needed. Ideal for isolated or difficult-to-access sites.

External Hybrid Combiner Unit (ECHU)

ECHU is designed for high power combining and distribution.

When the need for traffic capacity grows, the EHCU allows a doubling of the number of carriers without adding antennas or antenna feeders. Hardware as well as installation and site fee costs can therefore be kept at a minimum.

The EHCU can also be used for in-building distributed antenna systems.


External Hybrid Combiner Unit (ECHU)


Tower-Mounted Amplifier (TMA)

The Tower-Mounted Amplifier (TMA) filters and amplifies Radio Frequency (RF) signals received by the antenna before being sent to the RBS.

Transmission (TX) signals from the RBS are filtered but not amplified before being sent to the antenna.


Repeater Solution

With the ever increasing focus of cost vs returns in wireless networks, repeaters (cell extenders) offer a cost effective solution to operators to provide coverage at a fraction of standard BTS site costs. Repeaters are ideal in scenarios where coverage is the prime objective.

These repeaters are ideally suited for use as a Gap-Filler to optimise network coverage.

Smart Radio Concept – SRC 4 Way Receiver Diversity

The SRC solution is to cover large rural areas with low capacity coverage therefore cutting costs of building new sites to complete the RF plan.
