Qualcomm Technologies has introduced its first 5G
NR-spectrum sharing prototype system and trial platform. This new prototype is
based on the company’s sub-6-GHz and mm-wave, 5G, NR, E2E prototypes, which
include both base station and UE. It supports wide radio-frequency (RF)
bandwidths over 100 MHz, capable of delivering multi-gigabit-per-second data
It also supports a new integrated subframe design for significantly
lower OTA latency than what is possible in today’s fourth-generation (4G) LTE
network. The test bed is expanded to support listen-before-talk (LBT)
technology, wide-band waveforms with low latency, and enhancements in the radio
and network protocols.
Qualcomm announced its Snapdragon X50 5G modem,
making it the first company to announce a commercial 5G modem chipset
solution. The Snapdragon X50 5G modem will initially support operation in
mm-wave spectrum in the 28-GHz band. It will employ MIMO antenna technology with
adaptive beamforming and beam tracking techniques, which facilitates robust and
sustained mobile broadband communications in nonline-of-sight environments.
800-MHz bandwidth support, the Snapdragon X50 5G modem is designed to support peak
download speeds of up to 5 Gb/s. It is designed to be used for multimode 4G and
5G mobile broadband. The platform will include the modem, the SDR051 mm-wave
transceivers, and the supporting PMX50 power management chip. The first commercial
products that will integrate it are expected to be available during the first
half of 2018.
NEC Corporation announced that it has developed a prototype
of a massive-element (approximately 500 elements) Active Antenna System (AAS)
for base stations that supports the 28-GHz band. NEC’s simulation trials of the
newly developed AAS, which adopts beamforming, achieved up to 1 km in
long-distance communications in 16 respective directions on 28-GHz high-RF
bands, at a communications speed of 30 Gb/s or faster per cell and spectral
efficiency 20 times greater than LTE on a per-communication area basis.
The latest edition of the Ericsson Mobility Report forecasts
that there will be 550 million 5G subscriptions in 2022. North America will
lead the way in uptake of 5G subscriptions, with a quarter of all 5G mobile
subscriptions in 2022. Asia Pacific will be the second fastest growing region for
5G subscriptions, with 10% of all subscriptions being 5G in 2022. The report
also forecasts that, in 2022, there will be 8.9 billion mobile subscriptions,
of which 90% will be for mobile broadband.
Ericsson announced that it is commercializing what it
asserts is the world’s first 5G NR for massive MIMO, with the first deployments
coming in 2017. Together with the Ericsson 5G Plug-Ins and its Radio System
Baseband 5216, Ericsson claims to be the first to deliver all components of a
5G access network.
AIR6468 combines advanced antennas with a large number of
steerable ports to enable 5G technologies of beamforming, massive MIMO, and—building
on that—MU-MIMO. These capabilities improve user experience while enhancing the
capacity and coverage of the network and reducing interference.
