3GPP
3GPP (Third Generation Partnership Project) : A collaboration agreement that was established in December 1998 by standards bodies in Europe, Japan, China, North America and South Korea. The scope of 3GPP was to create a globally applicable 3G mobile-phone system that would fit into the International Telecommunications Union’s International Mobile Telecommunications-2000, or IMT-2000, project. 3GPP specifications are based on evolved GSM specifications, now generally known as the UMTS (Universal Mobile Telecommunications Service) system.
- 802.16d : Strictly speaking, 802.16d has never existed as a standard. The standard is correctly called 802.16-2004. However, since this standard is frequently called 802.16d, that usage also takes place in this article to assist readability.
- 802.16e : Just as 802.16d has never existed, a standard called 802.16e hasn’t either. It’s an amendment to 802.16-2004, so is not a standard in its own right. It’s properly referred to as 802.16e-2005.
- 802.11 : IEEE standards for wireless LANs with specs for 1-2, 11 and 24 Mbps with access points typically covering 50-100 meters each.
