GSA reports on status of LTE in unlicensed and shared spectrum

Thursday, January 17th, 2019

LTE in unlicensed and shared spectrum remains at an “early stage” worldwide with interest “high,” according to a report published by the Global Mobile Suppliers Association (GSA). Technologies discussed in the report include LAA, eLAA (LAA with uplink support), LTE-U, LWA (LTE Wireless-LAN Aggregation), LWIP (LTE WAN Integration with IPSec tunnel), and US-oriented CBRS. These are described in the report.

Wi-Fi Alliance reports some consensus from its Wi-Fi/LTE-U Coexistence Test Workshop

Sunday, November 22nd, 2015

In a November 20 FCC filing, the Wi-Fi Alliance reported on recent meetings with FCC staff on the subject of Wi-Fi/LTE-U coexistence. The Alliance says consensus was reached on the following points at its November 4 Coexistence Test Workshop:

  • The LTE-U specification can be further refined to provide greater clarity, and recent updates to the specification are a good step forward
  • A broader set of test scenarios than currently exists is likely necessary to test LTE-U’s fairness to Wi-Fi
  • Stakeholders are committed to collaborating within Wi-Fi Alliance to develop an industry agreed test regimen for LTE-U devices

A follow-up workshop is scheduled for the week of February 8.

In LTE-U, different companies can come away with different views of the same event. We’ll see if these consensus points hold.

IEEE 802 and 3GPP step up collaboration on LAA

Monday, March 23rd, 2015

IEEE 802 and 3GPP are working together more on coexistence of Licensed Authorized Access (LAA) and Wi-Fi. Since November, each group has made a presentation to the other. There’s been an exchange of liaison statements, the latest on March 18 when IEEE 802 sent 3GPP two statements containing several requests and recommendations.
