Sector Makes Progress on Unlicensed LTE Coexistence 888011000110888 The Office associated with Engineering and Technology and the Wireless Telecommunications Bureau have been closely monitoring industry efforts to ensure that new versions of LTE technology can co-exist with Wi-Fi and other unlicensed gadgets operating at 5 GHz. The Commission’s rules for unlicensed devices are designed to prevent dangerous interference to authorized radio solutions through limits on transmitter energy and spurious emissions. Industry has evolved standards such as Wi-Fi, Bluetooth, plus Zigbee within the framework of these guidelines, generally with the intention of ensuring cooperative sharing of the spectrum by unlicensed devices while recognizing that such devices are not protected from disturbance. This past March the particular 3GPP, which is an international standards body, developed a LAA (Licensed Aided Access) standard that is designed to allow unlicensed devices using a version of LTE to operate under the provisions for unlicensed at 5 GHz. LAA contains features such as listen-before-talk to ensure fair sharing with other unlicensed devices. We are aware that equipment manufacturers have got since developed devices based on this standard and we will proceed to grant devices certification for LAA devices that will meet the Commission’s rules. LTE-U (LTE for unlicensed) is a specification that was developed and backed by a group of companies within the LTE-U Forum. The various stakeholders agreed to engage in a process established by the Wi-Fi Connections to evaluate the coexistence of LTE-U with Wi-Fi. This process culminated in a co-existence evaluation test plan that was released on September 21, 2016. The next step will be for industry to make use of the test plan to evaluate the co-existence associated with any LTE-U devices. Throughout this process we have strongly motivated industry to address and resolve expressing concerns while preserving the theory of permission-less access for unlicensed devices throughout the spectrum. Such gain access to has generated countless innovative products for consumers. We recognize that development of the co-existence test plan is a difficult process involving various compromises by all of the stakeholders. We are pleased with the progress that has been made. OET and WTB can continue to closely monitor the roll-out of unlicensed LTE technology to ensure there is no detrimental impact on consumers.
