There are literally hundreds of fixed WiMAX deployments going on in the world... a large amount of them are using Airspan's equipment (Airspan is ranked #1 in certified fixed WiMAX equipment deployed). Buzz Broadband is the ONLY ISP in the world that is having difficulties with WiMAX or Airspan's equipment. Doesn't this sound strange to anyone? Did anyone call Airspan to get their side or are they believing everything one small ISP says that will soon be replaced by OPEL and the national WiMAX network?

Public Statements Concerning WiMAX and Airspan by the CEO of Australian WISP, Buzz Broadband
This week, at a WiMAX conference in Thailand, the CEO Buzz Broadband of Australia railed at the audience that WiMAX was a “disaster”. CEO Garth Freeman made several disparaging remarks about the range of WiMAX systems and their ability to carry VoIP traffic.
Buzz Broadband deployed Airspan MicroMAXd, ProST, and EasyST equipment to around 200 users, the same equipment that is installed in many of the 100 or so other Airspan WiMAX deployments. In addition to broadband services, Buzz Broadband intended also to offer VoIP services to its subscribers. Mr. Freeman’s recent statements highlighted two complaints: the range of the solution, and the quality of service (QoS) capabilities for voice traffic.
With regard to range, although Airspan offers both micro-cell and macro-cell base station solutions, Buzz Broadband opted to go with the less-expensive micro-cell base stations in order to reduce cost. This was a well understood tradeoff of cost vs. range. In support of larger cell radii, particularly in support of indoor desktop CPE devices, Airspan offers the HiperMAX base station, which offers the best link budget in the industry for an 802.16d-2004 solution.
Regarding QoS for VoIP, MicroMAX certainly offers appropriate QoS for wire-line quality voice support, but, as an access technology, can only do so for the portion of the link between the user device and the base station. In the case of Buzz Broadband, we know that there were significant under-provisioning issues in the core network which connected the Airspan equipment to the Internet. Very early in the relationship, Airspan technical services determined that Buzz’ backhaul network was considerably under-dimensioned (again to save cost) and lacked sufficient QoS, and that these factors were the direct cause of VoIP quality issues in the network. Airspan even went so far as to offer to fund a third-party analysis to help Buzz understand these issues. Both Airspan’s help and third party assistance were refused by Mr. Freeman.
At Airspan, we pride ourselves on our customer service and excellent products. In the case of Mr. Freeman’s company Buzz Broadband, we exhausted all avenues to help this customer re-engineer their core network and resolve these service issues. In the end, with Mr. Freeman rejecting help from the outside, the technical and financial resources of Buzz Broadband were not sufficient to deploy a functioning network to the satisfaction of its customers. We regret the distress caused by Buzz’ poor network architecture decisions to the customers in need of Broadband Internet access and VoIP services.
It is unfortunate that Mr. Freeman felt the need to broadcast his difficulties in such a public fashion. WiMAX has proven to be enormously successful from a technical standpoint, and Buzz’ allegations, even when so easily dismissed, are a distraction to the WiMAX industry and ultimately a disservice to the millions of satisfied broadband wireless access consumers worldwide.
If you should have any questions regarding this or any other concern, please don’t hesitate to contact me at Airspan on 561 893-8643 or dbyrne@airspan.com.
Best Regards,
Declan Byrne Chief Marketing Officer Airspan Networks, Inc.

Buzz Broadband was operating a fixed WiMAX service that used 3.5 GHz spectrum. It requires line-of-sight; Sprint is working with mobile WiMAX in 2.5Ghz spectrum which does not require LOS and has better building penetration.

I didn't mean to imply that WiMax is objectively having problems -- but this kind of about-face from a provider is certainly newsworthy... I for one am very much looking forward to Xohm in the U.S!
