To Beamform or Not to Beamform: Can Beamforming Help WiMAX Operators to Lower Deployment and Operating Costs?
Feb 01, 2010
As WiMAX operators deploy new networks or expand existing ones, they face multiple choices in the selection of base station equipment. How can WiMAX operators choose the hardware solution that is most cost effective and has the faster return on investment (ROI)? We addressed this question by analyzing the capex and opex requirements for a five-year period, using radio access network (RAN) equipment with multiple input, multiple output (MIMO), beamforming (BF), and a combination of MIMO and BF.
Mobile broadband: When is it profitable?
Jan 28, 2010
See our article on Fierce Wireless on how revenues-per-MB compare to cost-per-MB for LTE, HSPA and WiMAX. With the explosive growth in data traffic, can mobile operators preserve their profit margins for data services?
Extending the benefits of WiMAX to unlicensed bands
Nov 17, 2009
WiMAX is only available for licensed bands (2.3 GHz, 2.5 GHz, 3.5 GHz and others in the future) for which a certification program has been defined by the WiMAX Forum. What if an operator wants to use the same core technology (the IEEE 802.16 standard is defined for any spectrum band up to 6 GHz) in an unlicensed band such as the 5 GHz band or the US 3.65 GHz ones? Of course the equipment will not be certified, but it can still provide the functionality and performance of WiMAX technology.
