- The Physics of RF The physics of RF propagation demonstrate that as the frequency of operation increases - the coverage radius reduces for a given output power Real issue is with reflections – higher frequencies have a harder time bouncing off of structures, getting around corners, and seeing through walls Where reflections are less of a concern – 3.5 and 2.5 actually will perform very similarly Mobility *will* perform over 3.5 Traditional cellular networks operate at frequency bands much lower than 2.5 GHz offering advantages in network dimensioning. However, the enhanced air interface and advanced, multi-antenna techniques offered with WiMAX allows the platform to overcome many of the disadvantages of the higher frequency of operation. As we move from Coverage to Capacity focused build out – 2.5 and 3.5 look the same WiMAX networks deployed at 3.5 GHz may require almost 30% more sites for a given coverage area than a 2.5 GHz installation. However, in deploying those additional sites, the 3.5 GHz network will also have 30% additional capacity inherently built into the system. As a result, the 3.5 GHz network will be able to absorb a greater rise in data consumption on the network over time and forgo additional capacity focused build out longer than a 2.5 GHz system. The increase in sites at 3.5 GHz results in approximately 13% increase in total cost of ownership for the system over 2.5 GHz. (Fixed costs common to both a 2.5 GHz and 3.5 GHz network including such operational line items as subscriber acquisition, systems integration and network management results in the 30% increase of sites to contribute only a 13% increase in cost of ownership) It is important to note that over time as capacity increases and the 2.5 GHz system requires investments in new build out earlier than the 3.5 GHz system Both the 2.5 GHz and 3.5 GHz system will demonstrate parity in cost of ownership. 3.5 is cheap! 3.5 GHz has been demonstrated globally to have significantly lower price tag than 2.5 GHz Advice to the audience – if you have the chance to buy 3.5, run away with as much as you can carry! Can take the savings from spectrum expense and apply toward capital spend in the network – and displace the cost of the additional sites (and still bearing the benefit of added capacity)
