MPLS & Relevance in WiMax

WiMAX is not dependent on MPLS but the IP base infrastructure. ...but as this technology need to lead in the market & compete with its rival technologies. ...& offer Multiplay services...that hasnt been offer before...The Technology developers.. .combine all the best of the Technologies to built the Converged/Unified Network.

Aim of WiMAX is to offer,

• Broadband Wireless Access (Huge amount of bandwidth per user) .. so that every user can enjoy the Voice/Video/ Data Services over the same Last mile by spending minimum possible $$$.
• More Strong Coverage: To target Metropolitan areas, so that single BS can cover more n more business area.

For offering good services...with the above mentioned aim..it is necessary to have all three segments of networks with the huge capacity to handle VAS like Voice, Video, Data. These segments are,

Access: WiMAX RF interface offer good bandwidth using OFDMA & its varients.

Distribution/ Aggregation: WiMAX recommend Metro Ethernet for backhualing WimAX users traffic to ASN Gw....but u can also us Ethernet Microwave, E0SDH or Existing TDM/ATM network.

Core: Currently available Core network technologies are TDM, IP, FR/ATM, MPLS. MPLS is the most powerfull & most widely adopted technology in the World. Currently worldwide oeprators are already using MPLS in their existing 2G or 3G core...along with TDM by some operator..So WiMAX chooses best of the best methodologies to compete in the market.

Now the second question can be What is MPLS & What it can do for any network (including WiMAX)? Check the following detail list of MPLS related documents present at Xpedient Portal Files Section.
