EE Combines More 4G and 5G Spectrum for Even Higher Data Rates

You may be aware that the most common flavour of 5G in use today is known as 5G Non-Standalone (NSA). This allows the operator to combine 4G and 5G spectrum to achieve higher data rates. EE is one such operator in the UK. 

In a recent announcement, EE said that it has become the first European network to successfully aggregate a 5G signal using seven different spectrum carriers, including its existing 3.4GHz and new 3.6GHz 5G channels. The press release said:

This breakthrough will deliver new benefits for EE customers, with 5G data speeds topping 2.2Gbps in lab testing and expected real-world speeds of over 1.7Gbps on the network. The innovation means a major boost in 5G network capacity, using a total of 170 MHz of Bandwidth, and could deliver the fastest available 5G in some areas of the UK.

Working in collaboration with Qualcomm Technologies at BT’s Borehamwood lab, the EE network can now deliver a 5G signal using seven radio carriers, including some spectrum EE acquired in Ofcom’s spectrum auction last year. Using five 4G (LTE) carriers and two 5G (New Radio), it is the first time any European network has achieved this feat. A mobile test device featuring the Snapdragon® 8 Gen 1 Mobile Platform with Snapdragon X65 5G Modem-RF System was used to achieve the milestone.

While the press release doesn't detail the exact spectrum quantity in each spectrum, it specifies:

5 x LTE carriers = 1.8GHz (2 carriers), 2.1GHz (1 carrier) and 2.6GHz (2 carriers)

2 x NR carriers = 3.4GHz and 3.6GHz

Based on the spectrum holding, it can be assumed that 2x20 MHz was used in 1.8 and 2.6 GHz and 10 MHz in 2.1 GHz band was used. All these 5 carriers were carrier aggregated in LTE. 40 MHz of 3.4 GHz and 3.6 GHz was carrier aggregated in 5G. These were both used with dual connectivity to achieve the data rates specified above.

BT / EE has many firsts in the UK to their name so it's no surprise that their users will be able to enjoy top speeds going further. One final note is to point out that for the consumer segment, BT will use the EE brand as can be seen in the Tweet below.

Rakuten details its Open RAN and Innovation Journey


In a recent Qualcomm event, the CEO of Rakuten, Mickey (Hiroshi) Mikitani and Tareq Amin, CTO of Rakuten Mobile did a joint presentation laying down the innovation that has helped create the most advanced open mobile network.


Recently, Singapore newcomer TPG Telecom selected Rakuten Mobile as its partner to run OpenRAN trials on a new network in the city state, advancing toward a 4G service launch this year.

Anyway, here is the clip from the video of Qualcomm's live stream that they did instead of MWC 2020 (that was cancelled due to coronavirus fears) that details Rakuten Mobile's innovations.




There was quite a bit of discussion around this as you can see from the tweet above. As it says, the whole network is 4T4R and the advanced radio feature support include NB-IoT on every Node B.


There is of course question around the cost of the server and that it would require to be dedicated for a site.

Light Reading has a good summary of the presentation if you rather prefer to read than watch. It's available here.
