ZDNET's cardinal takeaways
- My 5G roadworthy travel tests included rigorous investigating connected 3 Google Pixel phones.
- Signal reliability mostly proved bully to decent crossed 3 large interstate carriers.
- Network architecture, including non-standalone 5G, emerged arsenic a origin successful deployment.
5G made a fig of promises erstwhile it debuted. The archetypal was the quality to grip excessive capacity. I tested that committedness outside a shot playoff crippled this past October, and I recovered it to beryllium partially true. The different committedness was amended sum seashore to coast. Now, it was clip to caput retired and springiness that a try. How 5G could amended sum extracurricular of metropolis centers.

To bash this, I took those aforesaid Google Pixel 10 Pros connected a roadworthy travel crossed the astir boring road successful America (and, thankfully, a antithetic road home) done the bulk of cardinal Indiana and Illinois. I besides passed done parts of Kentucky and Tennessee. Since I unrecorded successful Chicago, I person recovered 5G sum to beryllium beauteous great, but what astir erstwhile I permission the large city?
That's what I wanted to find out. While you were astir apt buying for immoderate of the champion Black Friday deals you could find, we were driving for 13 hours from Chicago to Nashville.
How I tested
This clip around, I wanted to trial not lone web speed, but wide coverage. So, I took those aforesaid 3 Google Pixel 10 Pros — 1 each with an AT&T, Verizon, and T-Mobile eSIM paper and I attached them to a 2x4 conifer board. I plugged them into an Anker Solix C1000 Gen 2 portable powerfulness station.
Then I loaded up nPerf, which is an app that measures connectivity. There is really a ton of functionality built into this app, but for my purposes, I wanted to get an app that would measurement the connectivity and spot of a awesome arsenic I drove done the heartland of the Midwest. nPerf measures the location, carrier, awesome strength, and a ton of different utile accusation for web professionals astir 1,500 times per minute.

The institution graciously provided maine with a spreadsheet of each those stats. By the clip I got backmost home, I had implicit 120,000 information points to examine. Needless to say, it was beauteous comprehensive.
Also, each hr oregon so, we would propulsion implicit astatine the nearest exit to tally velocity tests. For this, I utilized an iPhone 17 loaded with 3 eSIMs, 1 each from the aforesaid 3 carriers. At the stop, I mounted the iPhone connected a tripod, ensuring the aforesaid positioning for each carrier. I cycled done each 3 carriers, moving velocity tests for each and signaling the results. All successful all, I had a batch of information to enactment with. Some of the results were surprising, immoderate were not.
The results
As you tin see, speeds were mostly fantabulous for the astir part. Out of 18 locations, each bearer reached the azygous digits lone twice. They mostly hung astir successful the treble and triple-digit areas, which is to beryllium expected successful this time and age. But there's 1 further origin to consider.

As we drove, erstwhile we deed the one-hour mark, we looked for a spot to propulsion off, specified arsenic a remainder halt oregon a state station. That's fine, but it's besides wherever a batch of radical halt for assorted reasons. If I were gathering web coverage, I would absorption connected areas similar that to physique up first. It's wherever the radical volition be. That's wherefore I wanted to trial the awesome each the mode down and each the mode back, and that's wherever nPerf steps in.
Let's not hide that carriers person been gathering 5G networks for implicit six years now. What does web sum look similar successful betwixt those hotspots?
Standalone 5G vs. Non-standalone
One of the things that amazed maine was that of the 3 carriers, lone T-Mobile managed immoderate connectivity with a non-standalone (NSA) configuration. Non-standalone 5G deployments trust connected existing 4G architecture to assistance with immoderate of the basal nuts and bolts of establishing and maintaining a 5G connection. A standalone 5G connection, connected the different hand, utilizes 5G infrastructure from the crushed up.

NSA networks are faster and cheaper to acceptable up due to the fact that they utilize existing infrastructure; however, SA 5G is considered the semipermanent solution. The cardinal quality comes successful latency. Since NSA networks utilize 4G to found and support connections, latency tin beryllium affected. The clip this makes the biggest quality is successful gaming oregon successful distant power applications.
In those cases, latency needs to beryllium arsenic debased arsenic possible. In regular day-to-day kinds of activities, you won't truly announcement overmuch of a difference. Still, that metric tin springiness you an thought of what signifier of the 5G rollout the assorted carriers are in. So present are the results:
This illustration breaks down the 120,000 information points into 3 cardinal areas: benignant of web transportation (5G/LTE/etc), basal level of transportation (how galore bars your telephone displayed), and web transportation spot (in dBm -- higher is better).
Overall, T-Mobile appears to person the astir extended 5G coverage, some successful Non-Standalone and Standalone modes, with a sum complaint of 96.2 percent. That's remarkable, considering our car covered implicit 1,000 miles connected this trip. All 3 carriers had decent oregon bully awesome spot for implicit 80% of the trip, which is besides truly good. AT&T's and Verizon's 5G sum some clocked successful astatine implicit 35%, which is good, but not peculiarly impressive.
All 3 carriers had decent oregon amended awesome spot for implicit 90% of the trip. That's besides precise bully considering what I was expecting. The astir eye-popping metrics coming from this travel see Verizon's velocity successful Louisville, Ky, astatine conscionable nether 4GBps down.
As a broadside note, it seems similar Verizon ever has astatine slightest 1 eye-popping effect similar that, truthful bully for them. Another peculiarly absorbing stat is T-Mobile's 5G deployment. With numbers similar that, it's casual to judge that T-Mobile mightiness person what it calls the "best nationwide 5G network".
My verdict
All the same, it's indispensable to retrieve that I conducted these tests portion driving connected Interstates, which are typically congestion-heavy zones. It's worthy repeating, if I were going to physique a network, I would astir apt commencement with Interstates. If you roadworthy travel on state roads (which whitethorn beryllium the taxable of an nonfiction successful the future), past the communicative mightiness beryllium precise different.
However, I acceptable retired to trial 5G networks connected a roadworthy trip, which typically involves traveling on interstates and stopping astatine state stations on the way. Overall, it's reassuring to spot that each 3 networks are gathering appropriately, and careless of wherever you find yourself stuck connected the broadside of the road, there's a bully accidental you'll person a beardown capable awesome to telephone for help.
