FAQs
- What’s the function of splitters or couplers?
- when the building structure is too complicated or there is big loss due to thick walls, etc., splitters or couplers shall be used so that more antennas can be installed in more areas to distribute the signals to each corner of the coverage area.
- What antenna options do I have?
- Tech-in Communication is capable of supplying various of antennas which are available both indoor and outdoor environments at present. Normally clients are able to select for appropriate antennas via the recommendations by our team.
- Which kind of repeaters will be suitable for me?
- This depends on coverage size as well as specific frequencies need to be boosted. Tech-in Communication is going to tailored specified items based upon clients’ inquiries accordingly.
- Will repeater increase RF radiation?
- No, it will decrease instead.
As it can be searched easily through internet, the tower would “order” the mobile phone to increase its output power, in order to ensure successful connection when the mobile signal bar is few,there will be stronger mobile output power level when the mobile signal bar is less and the strongest one can reach 2W (GSM); moreover, the mobile phone is usually as near as less than 5cm to human body when people are in phone calls. Not only it influences the human bodies badly, but also run out of the battery power much more quickly; usually the mobile phone gets hot in such status.
The maximum power level of 10dBm~24dBm is 0.25W, and it decreases to be maximum 0.025W when reaching server antenna. And since the server antenna is installed over the ceiling or onto the wall,there is usually more than 3 meter away from the human body, 3meter away means at least 40dB propagation loss, or 10000 times less, 0.0000025W, and therefore it is too weak to influence human bodies though it is still a very good signal for mobile phones.
And when a booster is installed, it improves the mobile signals in the coverage, and the successful phone call can be connected easily with a much less power level of the mobile phone, thus it will reduce the RF radiation of the mobile phone tremendously.
- Why repeater?
- a. Blind or weak signal areas are formed if the buildings are too far away from CELL TOWER, or the buildings themselves shield or absorb signals.
b. There are too many complicated signals in the higher part of the buildings, therefore ping-pong switching effect has been formed and the signals fluctuate a lot, there are annoying noises during phone calls and call drops accordingly.
c. Elevators and basements are well-known for blind areas.
d. Downtown areas of the cities, which congested with many high-rise buildings, are usually the weak or blind areas.
e. The remote villages, mountains, hills, valleys, etc. are mostly populated areas with quite few mobile users, so the main target is to send coverage to these areas, and it will not be worthy installing a CELL TOWER tower, therefore a booster is a quite good option.
