Dear Friends!
Greetings to all. I Hope anyone of you have faced my problem and got solution too.
I am using sim900A for my security based project. I have designed my PCB as per in Datasheet. Current rating is almost more than enough(Using 3A current-lm2576 regulator) and also i am using 1db rubber type duct antenna. Signal strength is very poor.
How can i improve signal quality. Even china mobiles(worth for 1000rs) delivering good performance in signal strength. but i cant achieve for my module...Give your suggestion guys... Thanks in advance
