Parameter  WiMAX  LMDS  Range  50 Kms  5 Kms  Frequency  2-11 GHz  3 GHz  License  Combination of licensed and unlicensed spectrum  Licensed spectrum  Standard  802.16/16d/16e  Standards activities are currently underway at the ATM Forum, the Digital Audio Video Council (DAVIC), the European Telecommunications Standards Institute (ETSI), and the International Telecommunications Union (ITU).  Line of Sight  Required in case of 802.16 but not required in case of 802.16d  Required but can be done away with by using Orthogonal Frequency Division Multiplexing (OFDM)  Data Rates  Upto 75 Mbps  Upto 1.5 Gbps  Mobility  Using 802.16e, but this standard is likely to come only by 2008  No mobility offered suitable only for fixed wireless broadband
 
High data rates, high mobility along with wide area coverage  are the hallmarks of future Mobile Broadband services

Licensed Bands Required for assuring QoS and service reliability  Generally preferred in heavily populated areas Network scalability under control of operator Operator predetermine impact of license fees on business case Fewer operators means less crowding Unlicensed Unlicensed spectrum in rural areas means lower cost for the end customer Fast roll outs – no need to wait for the licensing process Counters the lengthy licensing process

Cellular operators adding  subscribers more than 7-8 million per month  Nov 07 -  8.3 million subscribers Dec 07 -  8.2 million Subscribers  ,[object Object],[object Object],[object Object],[object Object],[object Object]
[object Object],[object Object],[object Object],[object Object],Optimistic Side Wireless Cellular operators showing positive  signs , with 40 million subscribers hooked  to GPRS/EDGE Service …..which can be future potential customers for WiMax services .
It has severely impacted the EBITDA margins of the company , operators are looking for more spectral efficient networks and providing a provision for enhanced services and better QOS.  Increasing Traffic and Declining ARPU – Major concern for existing operators

Simplified DSL Architecture  The role of the Application Service Provider, the Network Service Provider and the Access Service Provider in the DSL reference architecture are similar to the role of the ASP, NSP and NAP in the WiMAX reference architecture.
The migration of DSL access networks towards Ethernet based aggregation introduces a V reference point in the architecture which allows the combination of a mobile WiMAX network with a DSL access network based on Ethernet bridging.
