EnglishThe system has both low power consumption and low maintenance costs. The standard building blocks make it easy to replace defective parts and are therefore very maintenance-friendly.
Small areas such as offices or rooms can be covered without overwhelming other areas. This is not the case with a passive DAS, where high power is required to compensate for the loss on the cable.
The system is completely transparent and operator independant, with no limitation in the number of communication channels. This is not the case with nanBTS, picocells or femtocells (Mobile Coverage Extender), where the number of available communication channels and bandwidth is always limited.
All 5 frequency bands, +700; +800; +900; +1800; +2100; +2600 MHz for 2G, 3G, 4G and 5G services are available.
This is not the case if nanoBTS, picocells or femtocells are used. These are limited to one or two frequency bands and technologies. Any new mobile phone technology then requires additional infrastructure and costs.
5- and 6-band systems are particularly suitable because the 700 and 800 MHz bands perform well over longer distances, while the 2600 MHz band is very useful near large cities, where the other frequency bands are often overloaded.
All built-in amplifiers are 100% linear and suitable for all future technologies, such as 5G.
The complete system of a master amplifier followed by a line extender provides a total signal amplification of 80dB with a bidirectional AGC automatic gain control of 40dB. This means that depending on the distance or changes made to the operator’s antennae, the system will automatically adjust for optimal user comfort. Each frequency band of the system is automatically adjusted independently of the other frequency bands.
We can manually adjust each frequency band to compensate for higher cable losses on higher frequency bands.
Multiple RF signals together tend to cause intermodulation distortion in both active and passive components when higher power levels, such as in passive DAS systems, for example, are used. Such distortion can temporarily block all communications in an entire frequency band. This is not the case with the GSM-CONNECT low power system.
A low-power DAS system is ideal for large buildings where signal levels fluctuate based on the diffusion or distance of users. With passive or more powerful active DAS systems, occasional PIM distortion is hard to avoid and even harder to trace.
DAS amplifiers located close to indoor or outdoor antennas and used for uplink and downlink signals, as in our system, provide much better signal quality. This is not the case with passive DAS systems where the uplink signals are severely degraded by long cables and passive splitters.
Due to the low power DAS system, each mobile phone in the area only needs a small transmitting power to connect to the mobile phone network. As a result, the user will experience less radiation and the battery of the mobile phone will last longer.
We install flexible, easy-to-install coaxial cabling, which allows us to easily reach any place in the building. Passive DAS systems require very stiff and thick cabling to keep signal loss low.
The system is completely modular, allowing us to split the existing cabling to create a new extension or a new set of extensions. We can expand an installed system to a maximum of 256 indoor antennas. Passive DAS systems cannot be modified with new extensions. Depending on the required coverage, they are limited to a maximum of 20 indoor antennas.
In our solution, each indoor antenna is directly connected to a series of filters that block unwanted signals. We do this to avoid possible interference from other radio equipment in use. That is not the case in a passive DAS system where every walkie talkie or other radio transmitter in the building can occasionally cause very difficult to detect PIM distortion.
