3GPP Ratifies Initial Specification for 5G
The 3GPP today ratified the first 5G specification, officially termed Non-Standalone 5G New Radio, or NSA 5G NR. The ratification took place at the 3GPP's RAN#78 meeting in Lisbon, Portugal, and capped off months of conferences to push the spec through before year's end. Balazs Bertenyi, RAN Chair, called it, "An impressive achievement in a remarkably short time, with credit due particularly to the Working Groups." Qualcomm led much of the effort, though network operators and other technology companies from around the world all played a role. The NSA 5G NR spec is the underlying framework that will be put to use by commercial 5G products, or things such as cell towers and base stations. The specification includes support for low-band spectrum (600 MHz), mid-band spectrum (3.5 GHz), and high-band spectrum (50 GHz). The 3GPP is still working on the Standalone (SA) 5G NR spec, which won't be completed until mid 2018. The NSA 5G NR and the SA 5G NR standards will together include the technology used by commercial entities, the air interface, and end users. The 3GPP said the actual, technical specifications for today's ratified NSA 5G NR will be published in the days ahead.

Qualcomm's new X55 standalone modem chip supports 5G in all major frequency bands as well as FDD and TDD modes. Support for FDD makes it the first chip to support T-Mobile's planned 5G network in the 600 MHz band.

Intel today introduced the XMM 8160, a 5G modem that will bring high-speed connectivity to mobile phones, computers, and other broadband devices in 2020. The modem supports the 5G NR spec, including both standalone (SA) and non-standalone (NSA) modes for fixed and mobile service.

The 3GPP today ratified another piece of the 5G specification, termed the Standalone 5G New Radio, or SA 5G NR. This spec is for 5G networks that are developed on their own, apart from legacy or pre-existing networks.

Sprint today voiced its support of the recently ratified NSA 5G NR specification and revealed its own plans for deploying 5G. The specification for NSA 5G NR includes support for up to 100 MHz on a single carrier (in the 2.5 GHz band) versus today's limit of 20 MHz per carrier.
