LTE-Unlicensed Angst Roils Wi-Fi Markets

Via ABI Research Media Releases

Jul 9, 2015

London, United Kingdom - 09 Jul 2015

​Operating in the unlicensed 5 GHz band, LTE-U’s coexistence with Wi-Fi has become a primary concern for the Wi-Fi industry which anticipates disruption on both the technical and business levels. Unlike Wi-Fi, LTE-U, as a propriety solution does not sense the channel activity before transmitting. Instead, it applies a form of time sharing using periodic time slots. Such scheduled transmission of LTE-U not only adds interference and increases collisions for Wi-Fi’s opportunistic transmission, but also defies the concept of fair sharing as it seizes complete control over the channel and Wi-Fi’s transmission window.

LTE-U provides clear advantages for mobile operators. It uses the free unlicensed spectrum to expand network capacity and does so without having to integrate another network, like Wi-Fi, within the cellular core. However, the advantages for end-users are not so clear. “LTE-U advocates focus on promoting its spectrum utilization superiority over Wi-Fi; promising better data rates and QoS. But will this significantly affect the average mobile user preferences? Operators should make a compelling value proposition in order to compete with mostly free uncapped Wi-Fi service,” says Ahmed Ali, Research Analyst at ABI Research.

Enterprises and venues also play an important role in this debate as the main host for LTE-U and Wi-Fi. “LTE-U small cells in the enterprise still face the same challenges of site permission and the lack of neutral-host support. Concerns of possible interference with Wi-Fi make it even a harder sell. In addition to ensuring minimum impact on Wi-Fi operation, operators need to win enterprise community over with a true problem-solving solution,” adds Ali.

These findings are part of ABI Research’s Carrier Wi-Fimarket research, which includes Research Analyses, Market Data, Insights, and Competitive Assessments covering regional shipments and deployments in addition to standardization process, major vendor solutions and recent trends.
