What is a BWA?
IEEE 802.16 an overview
IEEE 802.16 MAN Standard
will be able to connect 802.11 hotspots to the internet.
provides up to 31 miles of service area range.
has developed a point-to-multipoint broadband wireless access standard for systems in the frequency ranges 10-66 GHz and sub 11 GHz.
the standard covers both MAC and the PHY layers.
- two MAC system profile
- two primary PHY system profile
- defining MAC and PHY system profile for
IEEE 802.16e and HiperMAN standards.
-MAC and PHY enhancements
-Power consumption reduction
-Control by L2.5 Routing
MAC and PHY enhancements
- The proposal addresses the need for fast
correction , frequency and timing.
-The proposed PHY layer is based on
- The configuration offers simplicity for
both fixed and mobile implementations
Power Consumption Reduction
-Battery power for the Mobile Terminal
-Introduce two modes for the SS: Awake-mode and Sleep-Mode
routing as the BS
there are some important differences !!!
