Shyam Telecom - Repeater, Coverage, In-Building and DAS Solutions for GSM/CDMA/IDEN/PCS/DCS (All Frequency Bands)

Shyam Telecom is one of the major players in the Indian telecom industry and has a significant and established presence in telecom products, software development, manufacturing and provisioning of telecom services. With a solid track record of successful development and deployment of advanced radio communication technologies, Shyam is enabling operators worldwide to make the transition to the phenomenon of "seamless coverage".

Shyam Telecom has designed and launched cost-efficient radio solutions for extending seamless coverage for both GSM and CDMA for mobile communications networks. Shyam Telecom provides a complete range of repeater solutions - RF as well as optical systems. These can be classified into the following categories:

• Indoor repeaters (band selective and channel selective)
• Outdoor repeaters (band selective and channel selective) and frequency translating
• Dual band repeaters for (900MHz and 1,800MHz) or (800MHz and 1,900MHz)
• Fibre-optic repeaters
• Tower-Mounted Pre-Amplifiers (TMPA)
• Turnkey indoor solutions, including accessories (inbuilding solution)
• Turnkey solutions including installation and commissioning of IBS and DAS
• Distributed Antenna Systems (DAS)

INDOOR AND OUTDOOR REPEATERS

Our range of repeaters provides full coverage for indoor and outdoor applications in the GREY AREA in which mobile users are facing the problems of call dropping and are not getting coverage.

Our repeaters are highly suitable for deployment in dense urban environments, tunnels and canyons for indoor applications where physical structures cause low field strengths, as well as in outdoor applications such as highways and rural areas. They can also be used as an efficient and low-cost alternative to base stations in areas where coverage is more critical than additional capacity.

Shyam can provide you with complete turnkey solutions for both indoor and outdoor applications. With a proven record of establishing GSM network for 1.3 million subs, Shyam has come a long way in providing complete turnkey solutions from planning the network till O & M.

INBUILDING REPEATER WITH INTERIOR AND EXTERIOR ANTENNAS

Shyam's inbuilding repeater solution improves weak cellular phone signals inside the house, office, hotel and restaurant, underground parking etc., enabling customers to use cell phones even when calls are made deep inside buildings.

Shyam provides a complete inbuilding solution with all accessories (coupler, connectors, cables, etc.) combined with interior ceiling mounted antennas and an exterior mounted Yagi or Panel antenna. The system's amplifier boosts the signal level for distribution within interior areas, reducing the problem of dropped calls and signal fades. Shyam's building repeater packages can also be used in mobile applications, improving the voice quality and range in areas of poor cellular coverage.

OPTICAL RF REPEATER SOLUTION

Optical RF repeater systems are an excellent choice for providing RF coverage with high and low power solutions for indoor as well as outdoor locations where distance or the structure itself interferes with base station coverage.

High-power solution:

• Power output up to 10W
• Covers a distance of up to a 20km range

Low-power solution:

• Dual band solution of 13dBm power output
• Up to 60 remote locations can be covered

FREQUENCY TRANSLATING REPEATERS

Shyam's frequency translating repeaters do not need isolation between donor and server antennas, as the frequencies between remote and master are different from the serving frequencies. So the operator can cover large distances using these repeaters.

These systems are used for outdoor applications such as tunnels, highways and less busy traffic areas.
