THE 3G NETWORK

Mobile Telecommunications Systems, or UMTS. This definition of 3G has been rolled out over networks existing GSM (Global System for Mobile) networks.

In addition, 3G type services are offered today on CDMA (Code Division Multiple Access) networks, as well. This means is that, through technology advancements, wireless data can now be offered on multiple types of cellular networks. Most end users have no idea whether their service is a GSM based service, a CDMA based service or an older generation service. Today’s users just know that they want 3G, and many are willing to switch carriers in order to obtain internet and application capabilities on their phones.

HOW IS A 3G NETWORK DIFFERNT?

The overall premise that allows 3G networks to offer more services than traditional wireless networks is the fact that 3G technology uses the existing radio spectrum on which it operates more efficiently, so that each service uses fewer of the available radio waves. When each service needs fewer waves, more services can be offered simultaneously. It is this efficient use of the frequencies that has allowed what was once a simple voice only wireless network to evolve into being able to offer internet and other data services. 3G networks also offer greater security than legacy wireless systems because users authenticate to the network upon registration.

For wireless data capabilities (internet and email), 3G networks use High Speed Packet Access (HSPA). HSPA increases performance on the network by using improved modulation schemes and by refining the protocols by which handsets and base stations communicate. Under HSPA, 3G networks can offer data delivery speeds that are comparable to high speed internet access on your home computer.
