IEEE 802.20 - Overview

Overview

The baseline specifications proposed for this specification aimed considerably higher than those available on mobile architectures of the early 2000s. It was hoped to create a standard that would allow low-cost, always-on, and truly mobile broadband wireless networks, sometimes nicknamed as MobileFi.

IEEE 802.20 was specified according to a layered architecture, which is consistent with other IEEE 802 computer network specifications. The scope of the working group consisted of the physical layer (PHY), medium access control (MAC), and logical link control (LLC) layers. The air interface operated in bands below 3.5 GHz and with a peak data rate of over 80 Mbit/s.

The goals of 802.20 and 802.16e, the so-called "mobile WiMAX", were similar. A draft 802.20 specification was balloted and approved on January 18, 2006.

The IEEE approved 802.20-2008, Physical and Media Access Specification on June 12, 2008. This was made freely available from the IEEE 802 website.
