This article tries to describe some comparative points of LTE and WiMax to show their advantages and disadvantages.
1. Time advantage
WiMax is in the market while Long Term Evolution is still in the labs…So, in this point, WiMax has a clear time advantage over LTE: WiMax is present nowadays in numerous countries around the world.
There are already a lot of deployments, and WiMax is growing step by step in different markets, not only in urban zones,but also in rural and/or emerging markets. On the other hand, LTE is still in the labs, and forecasts say that until 2011-2012 (end of 2010 maybe) it will not be in the real market.
Availability of WiMax, HSPA and LTE
This fact can be an advantage for WiMax, because when LTE has arrived to the telecom market, WiMax will have already a solid market using it’s hardware. However, other technologies, like HSPA+, could decrease that advantage. HSPA+ could compete with WiMax meanwhile LTE arrives.
Spectrum efficiency of HSPA, WiMax and LTE in BPS/Hz
As it can be seen in the figure above, HSPA R7 can compete with WiMax R3 TDD in terms of BPS/Hz either in the download link or upload link.
