Here I Write about WMAN Standardization Which is universally design and fixed for all Operator. Let’s Check in Detail.
WMAN Standardization is inherited from 802.16 standard family
- CPE: Customer Premises Equipment
- AAS: Adaptive Antenna System
- OFDM: Orthogonal Frequency Division Multiplex
- QAM: Quadrature Amplitude Modulation
- BPSK: Binary Phase Shift Keying
ETSI has defined two specifications, Hiper Access (High Performance Access), which operates above 11GHz and Hiper MAN (High Performance Metropolitan Area Network) below 11GHz, which will be harmonized with 802.16a OFDM.
IEEE 802.16 (“Air Interface for Fixed Broadband Wireless Access Systems”) was approved in December 2001. This standard is for wireless MANs operating at frequencies between 10 and 66 GHz.
IEEE 802.16a is an amendment approved in January 2003, which adds to the original standard Operation in licensed and unlicensed frequency bands from 2-11 GHz.
IEEE 802.16e is a future amendment, which would extend the standard to cover “combined fixed and mobile operation in licensed bands” (2-6 GHz). The development of this work was approved in December 2002.
