17dbm CDMA Cell Phone Signal Repeater With 200m2 Coverage


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
