Massive MU-MIMO in FDD: ‘Simply outstanding’ in the uplink
Signals Research Group recently conducted what is almost certainly the first independent testing of 5G massive and Multi-User MIMO in FDD spectrum, in a live network.
What’s so great about 5G SA? Hint: It’s not network slicing
SRG President Mike Thelander says spectral efficiency – not network slicing – may be the real payoff from moving to 5G SA
Test shows uplink boost on Verizon’s 5G SA but most telcos still hold back
A test on Verizon’s 5G network with Ericsson radios shows 2.2-times better upstream spectral efficiency on 5G standalone compared to non-standalone.
AT&T’s open RAN in Dallas looks like the real deal, says SRG
“If it looks like Open RAN, smells like Open RAN, and tastes like Open RAN, then it must be Open RAN,” SRG President Mike Thelander says.
Testing Ericsson v. 1Finity in AT&T’s open RAN
Ericsson and 1Finity small cell radios in AT&T’s network went head-to-head in a benchmark performance test from Signals Research Group, preceding further rollouts later this year.
Worries about 5G uplink capacity for AI are overblown – analyst
Network test results from Signals Research Group show AI and AR apps have minimal impact on uplink capacity but a surprising spike in signaling traffic.
T-Mobile: Uplink is the next big thing
Thelander said he doesn’t read too much into Nokia’s involvement here. “It doesn’t surprise me that they made this announcement with Nokia versus Ericsson.
Verizon launches network slice for public safety
In recent tests, wireless network research company Signals Research Group (SRG) found that T-Mobile’s first responder efforts are paying off.
Is bigger really better in massive MIMO radios? SRG tests KT’s 5G SA
“We easily identified an obvious gain in downlink performance with the 64T64R radios,” SRG reported, going on to say that “there was a clear double-digit percentage gain with the use of more antenna elements.”
T-Mobile’s satellite messaging put to the test: Here are the results
Wireless network research company Signals Research Group (SRG) published some of the results from its recent tests of T-Mobile’s new satellite messaging service, running through SpaceX’s Starlink satellites.
