Scalability is a critical challenge to fixed-wireless deployments, both technically and financially.While a fiber network can physically connect every household in a service area (and deliver predictable performance), it is significantly more complex for a fixed-wireless network to deliver a line of sight to every household in a service area. Fixed-wireless network coverage is adversely affected by line-of-sight obstructions (including buildings and seasonal foliage) and weather.Also, fixed-wireless networks have inherent capacity limitations that sharply limit the number of users on a network using a given amount of spectrum. Fixed-wireless technologies will continue to improve but will not match the performance of fiber-optic networks-primarily because the existing and potential bandwidth of fiber is thousands of times higher than wireless.Suggest how and in what circumstances states should consider using public funds on fixed wireless technologies as a long-term solution to address residential broadband needs.Īt a high level, the report concludes the following:.Demonstrate whether fixed wireless can be a viable approach to delivering broadband to currently unserved residents in various deployment scenarios, such as in urban and rural communities, and.Provide an accessible guide to current and anticipated future fixed wireless technologies,.The resulting report, Fixed Wireless Technologies and Their Suitability for Broadband Delivery, addresses a range of critical technology and cost considerations related to fixed-wireless networks-and, as a point of comparison, to fiber-to-the-premises networks. The report seeks to do the following: To aid state and local policymakers, CTC Technology & Energy conducted an engineering analysis of fixed-wireless technologies and their suitability for delivering broadband service in various environments. Federal policymakers have addressed this subject to some degree: For example, the Broadband Equity, Access, and Deployment (BEAD) Program’s notice of funding opportunity (NOFO) preferences fiber over fixed wireless. As state and local governments and their partners plan to invest billions of dollars in federal funding to build broadband infrastructure, choosing the best technology will have significant long-term implications.
