IEEE 802.16e/Mobile WiMAX. Moise Effo. IEEE 802.16 Overview. IEEE 802.16e Protocol Stack. Network architecture. PHYSICAL Layer Description.
Quality of service (QoS) is provided via service flows. This is a unidirectional flow of packets that is provided with a particular set of QoS parameters
The inclusion of MIMO antenna techniques along with flexible sub-channelization schemes, Advanced Coding and Modulation all enable the802.16e technology to support a high data rate:
•peak DL data rates up to 63 Mbps per sector and
•peak UL data rates up to 28 Mbps per sector
in a 10 MHz channel.
Mobile Wimax can be considered as a real competitor for 3G for example in IP-traffic(VoIP/ IPTV).
Mobile Wimax supports seamless handoff which provides switching between base stations in vehicular speeds.
Mobile Wimax uses Scalable OFDMA multiplexing which maximizes the spectral efficiency.
