WiMAX and the Effects of Multipath

June 14, 2010 1:05 pm | Comments

By Ray Chadwick, Berkeley Varitronics Systems, Inc. WiMAX signals suffer from the effects of multipath and exhibit broadband fading characteristics that are very apparent in the spectrum of the received WiMAX signal (see Figure 1). It’s not a trick; OFDM modulation does not eliminate fading and is not always received with a flat spectrum.

WiMAX and LTE: Closer than You Think

May 19, 2010 11:04 am | by Joe Cozzarelli, Senior Director Broadband RF Products and Glenn Eswein, Director Of Product Marketing, Broadband RF Business, ANADIGICS | Comments

After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.
