The key usage of Mobile Signal Booster

How to debug mobile phone signal booster, cell phone signal booster is installed so as to avoid moisture leads to indoor coverage area is reduced, there are connections with waterproof tape wrapped.

With the rapid development of mobile communication networks, network coverage is expanding, but because of various buildings, roads continues to develop, so that the indoor wireless communication, there are some weak links still can not meet the needs of customers, currently mainly blind, weak area . After less than the cell phone signal through the loss of receiver sensitivity, resulting in poor cell phone calls. After less than the cell phone signal through the loss of receiver sensitivity. And more for floor, wall instability reflected signal, namely the conflict zone, mainly high-rise building regional radio signals from a plurality of cells. Lead to frequent switching (ie ping-pong effect) seriously affect the phone's normal communications. As urban high-rise towers, a large number of base stations moved to the suburbs, the capacity can not meet the communication needs of busy area that is mainly large traffic areas. Users can not access the mobile network communication. Relying on a base station or direct discharge station to increase coverage is not enough to strengthen its engineering costs consumed more complex and enormous.

How to improve the coverage of this, for the above problem. Achieve seamless indoor network coverage, improve call quality, but also to maximize the reduction of costs, from the above point of view, mobile signal booster has played a key role.

The main reason for bad cell phone signals and its hazards and annoyance

The main reason for bad cell phone signals

1, the blind signal will cause the phone is "out of service", "temporarily unavailable" or conversations disconnect phenomenon, this blind spot, including network coverage area outside such as workshops, factories, suburban, and rural areas has not been a place to build a network communications facilities , and by the shield of the city block and cell phone signal coverage areas that are not, such as in the office, bar rooms, elevators, underground places, buildings and other places. This situation can be solved through artificial gain, such as the installation of mobile phone signal booster and so on.

2, which is due to interference phenomena caused by bad signal. As the mobile phone signal is received through the electromagnetic wave propagation to work, radio base stations and mobile phones by launching a link between voice calls so as to achieve the purpose. Therefore, electromagnetic interference will adversely affect phone. When some of the electromagnetic interference in the air exceeds a certain level, the phone signal to noise ratio is reduced to the standard value, the phone will no signal or dropped the case, to check around the signal source and a source of interference.

3, due to the handover failure caused dropped. Network operators are radio signals transmitted by the base station for the user service, the base station range is limited, so in a region, there may be a lot of base stations. All base stations together is a network system, each base station has its own scope, beyond this range, it is necessary to replace the mobile phone base stations, thereby maintaining the cell phone is always on the network. When a user during a call beyond a serving cell to another serving cell, the user's voice channel but also from the original serving cell switching over, but if the new service area very busy at this time, there is no extra channel is assigned to user, then the serving cell handover fails, the user's call will be interrupted. The base station may increase the appropriate alleviate this situation, but will also increase the costs. Users can install mobile phone signal booster.

Also, because of transient network problems, or a particularly busy network, can also cause bad cell phone signals. For example, in the downtown business district, may also appear telephone dial out, it does not come to fight the case.

Bad cell phone signals, the major hazards and trouble

Bad cell phone signals will cause the battery to generate heat, batteries and motherboard burden, accelerated aging mobile phones, mobile phones and shorten battery life.

1, the signal will cause bad phone frequently dropped calls, calls increased.

2, cell phone signal radiated power full format 0.2 milliwatts, left a cell phone signal radiated power will be increased 1000 times, that will give your body harm.

3, the signal will cause bad call intermittent affect your normal call.

4, the signal is not good cause battery heat, accelerated aging, standby and talk time is reduced.

5, the signal will cause the phone back and forth bad search network, likely to cause damage to the phone.

6, when the phone signal is weak, the phone transmitting signal exceeds several times the normal value. In this case, long calls, it is easy to cause harm to humans. On the contrary, a good cell phone signal transmitted signal will be low, it will reduce the possibility of injury to the human body.

7, if the elevator fails, people trapped inside. Bad cell phone signals may cause trapped people on the inside can not be timely contact with the outside world, to come to rescue.

What is Mobile Signal Booster?

Mobile Signal Booster (Mobile Phone Signal Booster)

1. Introduction for Mobile Signal Booster

Mobile Signal Booster is for small area indoor distributed antenna system (also called coverage), the signal of the base station through a wireless access directly into the indoor coverage area, the base station through a small antenna signal is sent out, while receiving signal through the distribution system up to the base station, can effectively eliminate indoor coverage blind spots, interference suppression for indoor mobile communications users with stable and reliable signal, so that users can enjoy high-quality indoor personal communications services. Mainly used in indoor signal booster point small area coverage, covering indoor mobile communications blackout, covering the effect reaches the edge of the field strength-75dBm or more.

2. Where is the Mobile Signal Booster used

A.  Small area signal blind or weak signal areas, such as underground or semi-underground place of business, small basement, underground parking, etc.

B.  Complaints from small hot signal areas, such as conference rooms, a small supermarket, small shopping malls, offices, small public areas, etc. 

C.  Traffic and social influence of large areas, such as bars, cafes, dance halls, cafes, fitness clubs, leisure and entertainment, etc.

D.  Elevator, lift wells in particular, not aspects of the elevator cables laid.

Is Mobile Signal Booster with radiation?

Is Mobile Signal Booster with radiation? Is it harmful to healthy?

Answer: There are radiation, if no radiation, how can cell phone signal come? But when it is air, the health effects can be ignored.

Why not call indoor?

A: Yes, because the signal is not good.

Why is it a bad signal?

A: Yes, because the radiation is not enough.

Mobile Phone Signal Booster are generally less than 2KG weight power 25dBm (320mW) or less. Phones are generally power 33dBm (2W) or less. Cell phone signal strength in the general environment of power 10dBm (10mW) or less, the worst signal environment power of 33dBm (2W), adaptive.

The above two concepts clearly, and then remember: phone close to the head only one antenna is used. Many cable antenna amplifier is normally connected, from the people’s head at least 2 meters away.

(The following data from Android phones)

1. When the phone signal is less than-90dBm, the call will be a problem.

2. After the signal is amplified, generally less than -50dBm signal strength.

3. When you call: poor signal environments, the installation does not install the amplifier with the enjoyment of the human body radiation are as follows:
After installation: -50dBm signal radiation signal space below Hershey phone 10dBm (10mW) less radiation.
Not installed: -90dBm less space when the phone signal is poor signal radiation 33dBm (2000mW) less radiation.

(so what kind of situation small radiation?)

So the mobile signal boosters installed after a bad environment, call greatly reduced radiation.

Why do I say? ? There Androidr phone, please pick up your Android phone (the system comes with a signal test software). Click: Settings → About phone → status messages, then you will see a screen similar to the following. (By some manufacturers to turn over, and may show a different way)

Figure: -77dBm is that you are now the received signal strength.

Radiation is everywhere in the universe, the human tolerance to radiation than ordinary cell phone signal amplifier that is much greater (space after installing the strongest mobile signal booster generally not more than-50dBm).

Is a Mobile Signal Booster helpful?

Answer: Yes useful, but it need to meet some conditions.

Mobile Signal Booster useful conditions:

1, Place the position of the outdoor antenna must have a perfectly normal phone signal. Cell phone signal booster is relaying equipment, is the outdoor good signal through cable access, and then amplified and then forwarded to the indoor signal coverage is achieved. If placed outside antenna position signal is not ideal, forwarded to the indoor signal is not ideal.

2, The frequency to choose right. General Mobile Unicom is the same kind of frequency GSM900, telecom 2G and 3G frequency is CDMA800, China Unicom's WCDMA 3G signal is frequency, usually no 3G mobile amplifier, and now basically abandoned 3G mobile main push 4G.

3, The power to be able to meet environmental. Mobile phone signal booster power from 5mW to 200mW or so, the home environment is generally a good solution. If the power is used to host small or large with several floors of the area, there will be no effect. Too small to host, multi-cable antenna connection, the signal on the wire in exhaustion.

4, The installation method to be right. Installing the wrong way, it may cause the host to operate normally, but let the signal even worse. Installation Notes: a, install an outdoor antenna, outdoor antenna location must be able to receive a good signal, best call quality indoor and outdoor antenna can only reach the same position. b, internal antenna retransmitted signal received by the antenna can not let the outside, inside the antenna and the host should be more than one meter distance. c, the installation process, the wire material as possible, the loss of a large multi-wire. d, the distance between internal and external antennas, multi-wall separated by at least more than 5 meters apart, intermediate stop at least 10 meters less. e, the city installed outdoors as much as possible not to use Yagi antenna, the city has a strong outdoor signals, use flat or ceiling replaced because good directivity index flat ceiling is not particularly strong, Yagi also eyesores. As long as the host 100% lights on OK. Countryside or the base station are far away from the installation site, select the Yagi antenna. f, close to the amplifier from the base station, the base station antenna, the antenna can not be on the radio, outdoor best to use small antennas mounted on the ceiling or to see the location of the base station.

5, There may be installed after the call is not a normal situation, these situations are very small. Between buildings reflected signal, surrounded by too many base stations, indoor installation with frequency wireless devices may interfere with each other after.

The way to choose a Right Mobile Signal Booster

Cell phone signal is poor indeed very annoying, regardless of the couple in love relationships, or white-collar workers will be very easy to contact the business, in many cases only need a cell phone signal amplifier can be improved, then the cell phone signal booster how to choose it? Mobile Signal Booster of the basic components generally include the following: Mobile Signal Booster host, an outdoor antenna, indoor antenna, connectors and feeder.

1, the host selection generally depending on signal conditions to choose. If the signal is not good in the bottom part of the home, then according to the reasons leading to a bad signal, you should choose the most general can, for example, cell phone signal booster model coverage 100sqm 250sqm is used for the majority of poor inner city condition. If it is larger home, you can choose a mobile signal boosster 500sqm. If the business use, you need to have a high gain and output power, need to use 1000sqm coverage mobile phone signal booster; plant and villas as outdoor signal stronger indoor signal was blocked, so I chose a higher maximum output power 2000sqm mobile signal booster edition, For remote areas, suburbs, the application side TX output power is higher, and gain greater version, so as to effectively increase the maximum transmission area. For more extreme cases need to improve the signal, select high output power and gain the professional version.

2, an outdoor antenna Outdoor Yagi Antenna can be used, sucker antenna, patch antenna according to the specific situation  different antennas. Since Yagi antenna is a directional antenna, the installation is very difficult, generally of poor quality due to its noise factor inhibiting the host is poor, so only through sacrifice installation difficulty to make up, so if the host better quality, vast majority of cases should be used sucker antenna patch antenna goods, because you can easily install the first patch day on the window, in many cases do not need to pass through the wall, so the main recommended patch antenna. Only when the gain is not enough, for example, the outdoor signal is poor at home, in the suburbs or in remote rural areas, it is recommended Yagi antennas, Yagi antennas should note that when installed, can point the direction to try to move the transmitting station  to get the best reception results.

3, the indoor antenna indoor antenna is generally recommended to use a rod antenna, ceiling antenna manufacturers that use was mainly due to poor self-noise suppression, increase the gain to prevent self-excited adopted after the installation is very troublesome, and needs to be fixed on the ceiling. Host relatively good quality manufacturers usually choose a rod antenna, in some cases using high-gain antenna suction cup.

4, the wire feeder signal amplifier is generally coaxial cable, impedance of 75 ohms and 50 ohms both theoretically 50 ohm cable impedance matching, the better. Another better shielding effect, the host will be enlarged when the lower noise figure. Mobile signal booster accessories, the selection Signaltone dedicated feeders, four shielded coaxial cable, the market is more common is the use of cheaper double shielded coaxial cable. Generally longer wire line, to adopt better cable to reduce signal attenuation

What is a Mobile Signal Booster for?

Mobile phones as well as several other wireless devices have develop into new epidemics mobile signal booster from the century. Men and women don't need to lose their likelihood to be reached anyplace and anytime. They usually do not need to lose a possibility to communicate with their family and friends on the phone, even when there's a danger of dying from some sort of cancer, like brain cancer for example. And occasionally persons basically do not understand how to protect themselves from that danger employing cell phone signal boosters.

When we are speaking on the phone, the radiation coming from the device is really absorbed by the brain. This tends to make the permeability of your blood brain barrier larger. Apart from, the synthesis of stress proteins also soars. There was many different studies performed that proved that there is certainly unquestionably a very clear hyperlink in between the usage of mobile phones along with the increase of persons affected by brain tumors. Even though no exact conclusions can be drawn, the truth that cell phones enhance the threat of possessing cancer is quite apparent.

The much more we talk on the mobile phone, the higher would be the danger. Specially on the phone is consistently searching for network coverage and can not come across it. That is certainly what cellular phone boosters are for. These smaller but quite highly effective devices do not only resolve poor reception challenge for you, but also lower the risk of getting cancer, that is definitely extremely critical.

Mobile phone signal booster consists of an amplifier and an antenna. The amplifier boosts the signal and in such a way, that really compact and ineffective amplifier that is definitely constructed within the mobile telephone can cease searching for superior reception and thus, stop sending a lot of hazardous electromagnetic waves. Mobile telephone boosters are extremely useful and handy. Besides, making use of them it is possible to neglect about at least some well being challenges.
