Okay, let’s talk about the existing 3G networks first.

3G comprises several cellular access technologies. The three most common ones as of 2005 are:

• CDMA2000 – based on 2G Code Division Multiple Access
• WCDMA (UMTS) – Wideband Code Division Multiple Access
• TD-SCDMA – Time-division Synchronous Code-division Multiple Access

3G networks have potential transfer speeds of up to 3 Mbps (which is around 15 seconds to download a 3-minute MP3 song). For comparison, the fastest 2G phones can achieve up to 144Kbps (round 8 minutes to download a 3-minute song). 3G’s high data rates are ideal for downloading information from the Internet and sending and receiving large, multimedia files. 3G phones are like mini-laptops and can accommodate broadband applications like video conferencing, receiving streaming video from the Web, sending and receiving faxes and instantly downloading e-mail messages with attachments.

4G is not a technology. It is actually a set of parameters which focus on the use of IP and overall throughput that, once achieved, will enable that platform to be classified as 4G. The open-ended nature of the development cycle sets up a great battle between wireless technologies such as WiMax and post-3G cellular. The interesting thing is that each of these has easily understood advantages and disadvantages: Wireless tends to be cheaper and offer more bandwidth but has a smaller footprint, while cellular is pricier but covers more area.
