Unless WiMax deployment rates speed up, LTE will become the dominant 4G data network by 2015, predicts ABI Research principal analyst Phillip Solis. Farpoint Group's Mathias concurs. "LTE will have the footprint, services, and carrier and vendor support to make almost everyone happy, especially when coupled with Wi-Fi, which it will often be," he said. "WiMax isn't going away, but its opportunities for growth will be severely limited, and I don't think that there's much that can be done about that either from a business or a technology perspective."
Stanforth sees a role for WiMax as a public service, recalling the failure of many municipal Wi-Fi efforts, such as those in San Francisco, Chicago, St. Louis and Springfield, Ill., and speculating that WiMax might be better suited to the task. "Muni Wi-Fi flopped primarily because of both the lousy coverage of Wi-Fi and the cost to even get that -- it took 60-plus Wi-Fi [access points] per square mile to implement using a typical mesh architecture, whereas a single WiMax AP will probably cover well over a square mile. The economics of 'Muni WiMax' might make sense," he said.
Lori Sylvia, executive vice president of marketing at Red Bend Software Inc., which makes WiMax device-management software, thinks WiMax service delivery and infrastructure costs will need to decrease in order for WiMax to compete with DSL and cable. When all providers, no matter what technology they use, can provide multiple Mbit/sec. speeds, "then the buying criteria becomes like any other Internet service: coverage and cost," Sylvia said via e-mail.
Brough Turner, an independent wireless analyst and blogger, isn't optimistic. In an e-mail, Turner wrote, "The problem is WiMax products can never achieve the volumes associated with the GSM family of technologies (GSM, UMTS, HSPA, LTE). As a result, WiMax will always cost more to deploy, and WiMax handsets will be more expensive than comparable GSM family handsets. It doesn't matter if WiMax is 'better' than LTE or not, or that WiMax is ahead today. The installed base of GSM family technologies generates very high volumes for GSM family products. As those products migrate to LTE, LTE product volumes will drive costs well below WiMax costs."
It's not necessarily an either/or proposition, however. "In my opinion, LTE and WiMax will co-exist, as they are actually targeting different markets," said Schoolar of Current Analysis. "LTE for the most part is an extension of the current mobile ecosystem. It will primarily be used to do what we are doing today with 3G, but better. WiMax's primary market, however, will be more about fixed and portable services. As much as I hate to say it, WiMax really will be Wi-Fi on steroids. While WiMax's head start over LTE has diminished, I don't think it matters as much as people think, as the two technologies are running a separate race."
