3G technology - will it be more effective?

The 3G technology is creating revolution in almost every state of the US.  There are many features like speed, reliability and fast upload speeds. Two of the companies Verizon’s service and AT&T's from US have showed these results. You may also feel the speed and reliability of the wireless network that connects to your phone because it connects your phone to all fun, applications and services. But the real fact is that today's 3G wireless networks are collectively a work in progress and they are not perfect. This is because the independent research in this network is very hard to understand. In real the wireless signal is extremely variable by its nature. This is because of the obstruction by fixed objects like (buildings, trees etc…) as well as network load, weather, and tower locations affect the quality of the signal in this modern world. So these factors can cause a variation in signal service from a single signal service in day to day life.
