Ericsson (NASDAQ: ERIC) introduces a new radio product, AIR 3246, for Massive Multiple

Input Multiple Output (Massive MIMO), which is a complement to Ericsson’s global 5G radio

offering. AIR 3246 supports both 4G/LTE and 5G NR (New Radio) technologies and is

Ericsson’s first 5G NR radio for frequency division duplex (FDD). This launch will enable

operators – especially in metropolitan areas – to bring 5G to subscribers using today’s midband spectrum and boost capacity in their LTE networks.


Ericsson’s 5G Platform includes three previously launched time division duplex (TDD) radios

capable of supporting 5G and Massive MIMO, as well as core, transport, digital support and

security elements. The company has the most complete 5G portfolio in the industry, serving

the needs of the first movers in 5G.


Fredrik Jejdling, Head of Business Area Networks at Ericsson, says: “We now expand the 5G

platform that we introduced last February. The new radio will enable operators to enhance

4G capacity for their subscribers today and be ready for 5G tomorrow, using the same

hardware. We also complement the products with a set of network services, simplifying the

journey to 5G for our customers.”


Bridging from 4G to 5G


People are watching, sharing and streaming video and music more than ever. As such, the

demands on a sufficient speed are ever increasing. Ericsson analyzed 4G network

performance statistics from metropolitan areas around the world, and found that the

probability of a smart device suffering from insufficient speed can be as high as 20 percent

during peak hours. Massive MIMO is a key technology to bridge from 4G to 5G, adding

intelligent capacity and boosting user experience.


Stefan Pongratz, Senior Director at the Dell’Oro Group, says: “Just as carrier aggregation

has been key to adding needed capacity to mobile broadband networks, Massive MIMO has

the potential to be the primary capacity enabler in the next upgrade phase, providing a

smooth transition towards 5G. With an expected 2021 installed base of 10M LTE macro radios in high traffic and metro areas, service providers are expected to capitalize on the

improved spectral efficiency made possible with Massive MIMO.”


FDD Massive MIMO is part of a trial with T-Mobile US, on three sites in Baltimore, Maryland.

This will be the first time that standardized Massive MIMO will be used to carry commercial

LTE traffic using mid-band FDD spectrum.


Neville Ray, Chief Technology Officer for T-Mobile, says: “T-Mobile’s racing forward at

breakneck pace with Ericsson’s next-gen tech that advances LTE today and paves the way

for 5G tomorrow. While the carriers scramble to prop up networks caving under the weight of

unlimited, the Un-carrier’s rolling out advanced technologies to massively increase network

capacity and data throughput for customers. Translation – we’re making America’s best

unlimited network even better!”


Massive MIMO on FDD can increase network capacity up to three times and bring up to five

times better user throughput, boosting performance for the end users. Today’s global base is

primarily on FDD technology and devices, which separates uplink and downlink streams on

different radio frequencies.


Commercially available in the second quarter 2018, AIR 3246 will be part of Ericsson Radio



5G Services – preparation to launch


Complementing the 5G core transformation services introduced earlier this year, Ericsson is

now launching a set of services helping operators on the road to 5G in three steps: Prepare,

Mobilize and Launch. The services entail: Prepare for the first crucial steps based on

learnings from Ericsson’s trials around the world; mobilize by setting up the technical and

operational resources necessary for a successful 5G launch; and launch 5G services through

complete and rapid network rollout and ensure smooth operations of the services. These

new 5G services use Ericsson’s Engineered Intelligence approach, which builds on the best

of human and machine capabilities and are supported by automation, machine learning and

artificial intelligence tools.


Ericsson’s 5G platform comprises the 5G core, radio and transport portfolios, together with

OSS, BSS, network services and security.
