Sprint unveils HPUE to optimise 2.5GHz spectrum

14 Dec 2016

US mobile giant Sprint has launched its High Performance User Equipment (HPUE) solution, which it describes as ‘a breakthrough innovation designed to optimise 2.5GHz network coverage’. The new technology, which was unveiled at an event in New York City, is said to be capable of extending coverage by up to 30% to nearly match its mid-band 1900MHz spectrum performance, including indoors where an estimated 60% to 70% of all wireless traffic is generated. Testing was carried out in conjunction with China Mobile. Going forward, Sprint’s network is ready for the initial rollout of HPUE, including in its 250 ‘LTE Plus’ [tri-band carrier aggregation] markets and Samsung is expected to support HPUE in devices slated for commercial launch in 2017.

Gunther Ottendorfer, COO of Technology at Sprint, commented: ‘Sprint is a pioneer in high-band spectrum and our network performance is now at best-ever levels as we continue to deploy our 2.5GHz toolbox. TDD-LTE and 2.5GHz will be critical to our 5G future, and HPUE is one of our many innovations … You ain’t seen nothing yet!’

Certified by standard development organisation the 3rd Generation Partnership Project (3GPP) on 6 December 2016, HPUE is a new power class – Power Class 2 – for end-user devices such as smartphones, and is designed to improve the performance of TDD-LTE Band 41 networks worldwide. Aside from the aforementioned China Mobile, other key participants in the development of HPUE have been named as SoftBank, Qualcomm, Samsung, ZTE, Broadcom, MediaTek, Skyworks Solutions, Alcatel, Motorola, LG and Qorvo.
