Four barriers to network slicing

Considerations include operational readiness, business case development and go-to-market strategy A logical, virtual, end-to-end network slice that automatically comes into being to serve the exacting requirements of a particular horizontal or vertical use case—that’s a big part of the vision of 5G and the monetization...

MU-MIMO: A boost for 5G capacity and a ‘critical role’ in FWA

Testing on Verizon's network sought to illustrate real-world performance of MU-MIMO A new report from Signals Research Group tested the ability of Multi-User Multiple-Input Multiple-Output (MU-MIMO) to increase 5G site capacity and says that the technology will be a important component of 5G network support...

Test and Measurement: Getting a boost from HPUE

With the move into higher frequency bands (and TDD), there are coverage range and penetration losses. In standards work, 3GPP has created an option to compensate for this: High-Powered User Equipment, or HPUE. Originally aimed at supporting the communications range boost needed by first...

Test and Measurement: ‘Opportunities for improvement’ in Rakuten Mobile’s 5G Open RAN, SRG finds

Key takeaways from SRG’s testing of Dish’s network in Vegas

"Operators who have been rolling out 5G NR networks for some time have the coverage advantage," SRG says For some time, Dish Network has been promising a beta launch of its much-anticipated 5G network in Las Vegas, amid delays. That beta test phase with friendly...

Taking a look at Terragraph: SRG says it doesn’t disappoint

Over the past several years, Facebook's connectivity group has been focusing on research and development in communications network infrastructure, with an eye to how innovative approaches can reshape network economics and ultimately, benefit the company by connecting new users to the internet. One...

SRG talks ‘apples-to-apples’ network comparisons and interactivity testing

How do you approach network benchmark testing so that it represents the user experience in a way that's as reflective of real-world conditions as possible? And how do you best test the back-and-forth data transfers that determine the mobile gaming experience but aren't necessarily...

Fastest isn’t necessarily best: SRG puts three 5G networks to an apples-to-apples test

Speed, speed and more speed: So much of the consumer expectations, and industry testing and bragging, are focused on the new heights of speed that 5G can achieve. The question of which operator has the fastest 5G network is one which has recently been...

Qualcomm Webinar Series Part 2: mmWave: New use cases and insights from real-world deployments

During this presentation, you will hear about new use cases and features involving 5G mmWave, based on field testing that Signals Research Group has done in commercial networks in the United States. Topics explored include mmWave in the enterprise, 4K multi-screen content, fixed wireless access,...

SRG on T-Mo’s SA 5G: ‘Meaningful improvement’, but not necessarily for urban users

Upgrading to T-Mo's 5G SA: Big bucks for T-Mobile US made a splash with the announcement earlier this month that it had turned up Standalone 5G in an area encompassing 1.3 million square miles of its network. Signals Research Group wasted no time in getting...

SRG: 5G coverage maps are ‘optimistic’

Testing of 5G at sub-6 GHz frequencies concludes that mid-band LTE is "the weakest link" Even with low-band 5G New Radio deployments that would presumably provide more, and more robust, coverage than millimeter-waved-based 5G, carriers' 5G coverage maps are still "optimistic," according to new drive...

SRG puts 5G’s energy efficiency to the test

Is 5G a "battery vampire," as some have claimed, or is it actually more power efficient than LTE? It's a bit of a mixed bag, according to Signals Research Group. The testing company recently took to the streets of Minneapolis, Minnesota with a 5G-equipped Samsung...

eMBMS testing: Big quality gains, even with few devices

The use of LTE-Broadcast results in higher video quality as well as a more consistent viewer experience, according to recent testing by Signals Research Group -- even when relatively few devices are involved. SRG reported that its testing showed "dramatic difference" in video quality between...

Massive MIMO provides ‘real and meaningful’ benefits, SRG concludes

Massive multiple-input multiple-output provides "real and meaningful" benefits, according to a benchmarking report by Signals Research Group -- and Sprint is looking to leverage those benefits in both its preparation for the upcoming Super Bowl and for its eventual deployment of 5G. In testing on...
