License-exempt spectrum bands make it possible for operators who do not have access to licensed spectrum to deploy wireless broadband networks. Traditionally vendors have developed specific solutions for license-exempt operators, often based on proprietary technology that limits the flexibility and upgradability of their networks.
With IEEE 802.16e WiMAX, license-exempt operators have access to the most advanced wireless broadband technology on the market today and can take advantage of the same performance, ecosystem, and volume of scale that incumbent, nationwide wireless operators with licensed-spectrum can. While often positioned as a mobile broadband technology that operates in licensed bands, 802.16e WiMAX can also support fixed and nomadic services, and vertical applications in a range of frequencies up to 6 GHz, including license-exempt bands such as the 5.x GHz band and, in the US, the lightly licensed 3.65 GHz band.
As 802.16e WiMAX products for license-exempt bands are introduced in the market, operators need to know what the value proposition of using 802.16e WiMAX compared to alternative solutions is. How do they stand to gain from a technology that was developed to support mobility? Do they need the extra features that 802.16e WiMAX offers?
Why choose 802.16e WiMAX-based equipment?
The appeal of 802.16e WiMAX-based equipment to wireless operators either serving residential and business subscribers or hosting vertical applications is driven by the ability of the technology to meet operators’ requirements, both from a business model perspective and from a performance one. The strongest pull towards 802.16e WiMAX is that it is a technology with a well established evolution roadmap, with strong industry backing and a rapidly expanding ecosystem. The 802.16e WiMAX has a path toward the next WiMAX version, 802.16m, which 802.16d TDD WiMAX lacks. Operators with 802.16e WiMAX-based networks will be able to upgrade their infrastructure to 802.16m WiMAX when the equipment becomes available. Operators with 802.16d TDD WiMAX do not have this opportunity, unless they are ready to build an overlay network or entirely replace the old equipment with the new 802.16e one.
With the introduction of 802.16e WiMAX-based equipment for use in license-exempt bands, 802.16d TDD WiMAX is rapidly becoming a legacy technology, as it already is in licensed bands. Wireless operators that do not have a clear migration path to 802.16e WiMAX are concerned that their vendors might cease their development of new 802.16d TDD WiMAX-based products in favor of the newer standard. The availability, selection, and cost … Read the rest
