Comparison of TDD LTE And IEEE 802.11af Deployment in TVWS Band

Abstract

Comparison of TVWS solutions based on TDD LTE and IEEE 802.11af has been presented. It can be concluded that both technologies provide option for deployment in UHF TV band but selection should be made on multiple criteria such as type of end users, required technical parameters and overall price of the deployment. It is shown that proposed solutions could serve for alternative wireless broadband access in developed countries as well for underserved and low income population. It can be concluded that IEEE 802.11af will be superseded by IEEE 1900 standard based solutions in order to improve its' communication and coexistence performances while TDD LTE could be a better solution regarding throughput and costs of deployment if sufficient spectrum is available.

Review of V2X–IoT Standards and Frameworks for ITS Applications

“…IEEE 802.11af (White-Fi) and IEEE 802.11ah (HaLow) standards are also designed for various IoT solutions. The first of these standards works in the VHF and UHF bands from 54 MHz to 790 MHz (470-790 MHz in Europe and 54-698 MHz in United States), data transfer is available from 1.8 Mb/s to 35.6 Mb/s, and the designed coverage is up to 1 km [116]. Meanwhile, IEEE 802.11ah operates in the 863-868 MHz (Europe) and 902-928 MHz (North America) bands, with a coverage of up to one kilometer, and data rates ranging from 150 kb/s to 347 Mb/s [117].…”
