How can one 3G network be faster than another? Is it because of the difference in overhead bit usage for network management?
Can anyone answer this???
It's all determined by the number of users, the amount of data transferred among towers, and strength of the network.
For example, AT&T's network was extremely fast before the iPhone (hence the "fastest 3g network" claim). Once the iPhone was released, and users were draining network resources at a much higher rate than ever before, AT&T's data speeds became sluggishly slow. While it is still a 3g network, the amount of users cramming the network with all the data being transferred slows that speed down.
Verizon's network is able to handle the increased data transmissions because it covers a lot more area. The more towers, the less strain on the network from all the data being transmitted (hence the "most reliable 3g network" claim). Verizon's network is built to handle a lot of data...which is why the massive amount of users buying the Droid have not affected speed one bit.
Sprint on the other hand is in an interesting spot. Their 3g network is probably the fastest. The reason for it is due to the mass exodus of subscribers over the past few years. Because of all the room created by people leaving for other companies, Sprint's network is able to handle a great amount of data without problems (hence the "most dependable 3g network" claim).
This is also why there is a push for the LTE and WiMax networks. Carriers are in a tough spot...as they increase their subscriber base (which is the goal of every carrier) they put a higher strain on their 3g network and muck it up more. Eventually they'll be able to loosen things up with 4g, and be able to add more subscribers without fear of slowing their network down to a crawl.
