Hi Sam we have some operators in Italy using WiMAX in licensed and unlicensed. In licensed it works well, in unlicensed it woks "not so well"
I have heard some marketing guy saying things like "it works till 20 miles and it gives you a lot of bandwidth" which is technically wrong but it's a good commercial "white lie"..... the reality is "it works till 20 miles OR it gives you a lot of bandwidth" meaning that yes you can do 20miles but at lower efficiencies (=bandwidth) or you can have high bandwidth if you have near customers with a good signal. WiMAX does not do miracles Lately I have heard that some WISP/operators are "abandoning" WiMAX and moving to LTE or dual stack WiMAX/LTE because frequencies are usually "technology independent" and LTE seems more supported by some vendors and the new marketing magic word. The problem is that devices are really expensive so you must have some really good reason to convince the customer to buy that thing or you must be sure that the customer will never abandon you. So the WiMAX is not working in the WISP unlicensed business because if you have clean channels you can give the same service with unlicensed 5Ghz and at lower prices. Indeed for the unlicensed market there are two options: 1) the channels are empty/clean and you can do whatever you want even with a 5Ghz device 2) the channels are dirty/noisy and WiMAX does not work well there Regards > Today we had a company come to us pushing wimax.
