SRG's testing said that erratic voice, downlink speeds have improved
What difference has a year made in Dish Wireless' network performance in its inaugural market? Better voice quality and faster downlink speeds, according to recent testing and analysis from Signals Research Group.
SRG first tested...
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...
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...
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...
Rakuten Mobile's Open RAN 5G network leaves something to be desired in terms of both spectral efficiency and performance, according to new testing from Signals Research Group.
SRG conducted the tests over three days in late April, looking at both Rakuten's 5G and LTE networks....
"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...
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...
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...
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...
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,...
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...
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...
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...
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 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...
Analyst firm Frost & Sullivan has identified half a dozen drivers for the electronic test and measurement market over the next five years in a new report. Those drivers are: autonomous driving; 5G; the internet of things; data centers; power applications; and new, high-speed...
Verizon's official launch of its 5G fixed wireless access service is only two days old, but Mike Thelander and Emil Olbrich of Signals Research Group are already on the ground in Houston, Texas, field-testing the live network's capabilities.
Houston is one of four initial launch...
Ultra reliability and low latency of 5G a major enabler of factory automation, robotics and other industrial use cases
With the right technological stack in place, manufacturers could eventually operate what's called a "lights-out" facility wherein factory automation solutions--think smart, connected robots--could supplant the need...
Millimeter wave signals were more found to be more robust than expected and provided high speeds -- although not gigabit speeds -- at distances of several thousand feet from a node, Signals Research Group found in recent testing of Verizon's 28 GHz fixed wireless...
Understanding the end user quality of experience created by gigabit LTE
