In Building Solutions(IBS)
In-Building Solutions (IBS) provide mobile coverage inside an area, where the coverage, quality or capacity would otherwise not have been satisfactory.
In-Building Solutions (IBS) provide mobile coverage inside an area, where the coverage, quality or capacity would otherwise not have been satisfactory. IBS Passives are used by many operators and have been installed in multi-tenant high rise buildings, offices, complexes, airports, exhibition centres, subway stations, conference centres, hotels and shopping malls. IBS caters for cellular standards such as GSM900, CDMA, DCS1800/PCS1900, UMTS, HSDPA, LTE and non-cellular standards such as Wireless Lan and Bluetooth.
IBS enables Mobile network operators to offer improved services and therefore increase usage revenue and optimise the building value.
SRFS Teleinfra provides high-quality passive devices which deliver high-performance while maximising the network efficiency in the IBS network. Manufactured to the highest standards, the devices ensure proper active components functionality. They are available in a wide frequency range and options
DISTRIBUTED ANTENNA SYSTEM (DAS)
A Distributed Antenna System (DAS) is a system to deal with isolated spots of poor coverage inside a large building or area by installing a network of relatively small antennas throughout the building to serve as repeaters.
The antennas are physically connected to a central controller which is connected to the wireless carrier network’s base station. As Distributed Antenna Systems (DAS) operate on RF spectrum licensed to wireless carriers, an enterprise cannot undertake a DAS deployment on its own without involving at least one carrier.
Distributed Antenna Systems (DAS) can be active, passive or hybrid.

Passive DAS
In Passive DAS, the signal source (which is BTS outsite or Antenna on the roof) connects to a cellular amplifier or repeater, which then connects to the distributed antenna around the building or facility using coaxial cable and splitters. There is no amplification between the repeater and the distributed antennas, hence the name passive distributed antenna system. There are limitations to the reach of passive DAS solutions as they use coax cables to distribute signal, signal loss is higher than with active DAS. The further away the antennas are from the amplifier, the higher the signal loss. But they are considerably cheaper than active DAS. Because they typically rebroadcast the macro network’s signal, there is less need for carrier approval and coordination.
Active DAS
Active DAS employ amplifiers at the distributed antenna locations, and signals may be transported from the repeater to the distributed antenna locations via fiber, or CAT-5/6 cabling. The amplifiers amplify the signal from the repeater and provide a stronger signal to wireless units. They also amplify signals from the wireless units to provide a stronger outgoing signal. Active DASs may cover very large areas but at the expense of higher cost and greater complexity.
Hybrid DAS
A hybrid DAS combines characteristics of passive and active systems. Hybrid DAS uses some fiber cables for distribution of signal, but relies on passive coaxial cable for much of the signal distribution. The RRUs are separate from the antennas, allowing the system to use both fiber optic cable and coaxial cable to distribute signal throughout a building. Hybrid systems can be a good solution for medium-sized spaces, or unusual signal problems. Multiple passive systems can be linked by fiber cable to a remote amplifier unit.
