changing signal strength programmatically in android

I want to change the network signal strength programmatic-ally in android..Even though signal is full i want to make it 50% or even 0%. Friends is it possible..?If possible please开发者_如何学运维 me how to do it..Thanks in advance..

To answer your question, no it is not possible, the Android SDK only provides a method to get the GSM Signal Strength not set it. For more information on the android.telephony.SignalStrength object, check out this link

it is possible to change any information related to gsm like signalstrength or MCC or MNC provided your devcie is ROOTED. Only then you can use setprop to do so .Note you cannot set using java reflection method as it reads and caches it from the native methods. You have to used NDK on rooted phone .
