1.Introduction
With the rapid development of the mobile communication network, the network coverage is expanding
constantly, but due to all kinds of construction and road traffic are continuously developing, the indoor
wireless communication become weak and can't satisfy the demand of users,now there are following
problems:1. blind spot: signal is lower than the receiving sensitivity after it was loss, which cause bad
communication.
2. weak spot:The bad cellphone communication is mainly because the signal lower than the receiving
sensitivity after it was loss.
3. Conflicting spot: the wireless signal of high building comes from several districts and mostly is the
unstable reflected signal from ground and walls, led to the signal frequent changeing(i.e table tenis effect)
and affect the normal mobile phone communicate.
4. busy spot:it is main large social impact area, the base station can not meet the demand of the
communication and the user can not access mobile network for normal communication.
2.Futures:
1.Amplify indoor signal of blind area( conference room, hotel, the groud of large building ect)
2. Expand base station signal coverage.
3. Improve the sending and receiving signal coverage.
4. Reduce the radiation of cell phone to human body.
5. Extend the use time and battery of cell phone
