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.
