ZDNET’s key takeaways
- My 5G street journey exams included rigorous testing on three Google Pixel telephones.
- Sign reliability usually proved good to respectable throughout three main interstate carriers.
- Community structure, together with non-standalone 5G, emerged as a think about deployment.
5G made plenty of guarantees when it debuted. The primary was the flexibility to deal with extreme capability. I examined that promise exterior a baseball playoff sport this previous October, and I discovered it to be partially true. The opposite promise was higher protection coast to coast. Now, it was time to move out and provides {that a} attempt. How 5G might enhance protection exterior of metropolis facilities.
Additionally: We ran battery exams on 17 telephones – this mannequin lasted the longest
To do that, I took those self same Google Pixel 10 Execs on a street journey throughout essentially the most boring freeway in America (and, fortunately, a special freeway residence) via the majority of central Indiana and Illinois. I additionally handed via components of Kentucky and Tennessee. Since I stay in Chicago, I’ve discovered 5G protection to be fairly nice, however what about once I go away the massive metropolis?
That is what I needed to search out out. Whilst you had been most likely purchasing for a few of the finest Black Friday offers you may discover, we had been driving for 13 hours from Chicago to Nashville.
How I examined
This time round, I needed to check not solely community velocity however total protection. So, I took those self same three Google Pixel 10 Execs — one every with an AT&T, Verizon, and T-Cell eSIM card and I hooked up them to a 2×4 pine board. I plugged them into an Anker Solix C1000 Gen 2 transportable energy station.
Then I loaded up nPerf, which is an app that measures connectivity. There may be truly a ton of performance constructed into this app, however for my functions, I needed an app that may measure sign power and connectivity as I drove via the heartland of the Midwest. nPerf measures the situation, service, sign power, and a ton of different helpful data for community professionals round 1,500 instances per minute.

The corporate graciously supplied me with a spreadsheet of all these stats. By the point I received again residence, I had over 120,000 knowledge factors to look at. For sure, it was fairly complete.
Additionally, each hour or so, we’d pull over on the nearest exit to run velocity exams. For this, I used an iPhone 17 loaded with three eSIMs, one every from the identical three carriers. On the cease, I mounted the iPhone on a tripod, guaranteeing the identical positioning for every service. I cycled via all three carriers, operating velocity exams for every and recording the outcomes. All in all, I had quite a lot of knowledge to work with. A few of the outcomes had been shocking, some weren’t.
The outcomes
As you possibly can see, speeds had been usually wonderful for essentially the most half. Out of 18 places, every service reached the only digits solely twice. They largely hung round within the double and triple-digit areas, which is to be anticipated nowadays. However there’s one extra issue to think about.

As we drove, after we hit the one-hour mark, we regarded for a spot to drag off, akin to a relaxation cease or a gasoline station. That is advantageous, but it surely’s additionally the place lots of people cease for varied causes. If I had been constructing community protection, I might concentrate on areas like that to construct up first. It is the place the folks will likely be. That is why I needed to check the sign all the best way down and all the best way again, and that is the place nPerf steps in.
Let’s not neglect that carriers have been constructing 5G networks for over six years now. What does community protection appear like in between these hotspots?
Standalone 5G vs. Non-standalone
One of many issues that shocked me was that of the three carriers, solely T-Cell managed any connectivity with a non-standalone (NSA) configuration. Non-standalone 5G deployments depend on current 4G structure to assist with a few of the primary nuts and bolts of creating and sustaining a 5G connection. A standalone 5G connection, alternatively, makes use of 5G infrastructure from the bottom up.
Additionally: I lastly discovered a MagSafe automobile charger that handles bumpy roads (and it is on sale)
NSA networks are sooner and cheaper to arrange as a result of they make the most of current infrastructure; nonetheless, SA 5G is taken into account the long-term answer. The important thing distinction is available in latency. Since NSA networks make the most of 4G to ascertain and preserve connections, latency will be affected. The time this makes the most important distinction is in gaming or in distant management purposes.
In these instances, latency must be as little as doable. In common day-to-day sorts of actions, you will not actually discover a lot of a distinction. Nonetheless, that metric can provide you an concept of what part of the 5G rollout the assorted carriers are in. So listed here are the outcomes:
This chart breaks down the 120,000 knowledge factors into three key areas: sort of community connection (5G/LTE/and so forth), primary degree of connection (what number of bars your telephone displayed), and community connection power (in dBm — greater is healthier).
Total, T-Cell seems to have essentially the most in depth 5G protection, each in Non-Standalone and Standalone modes, with a protection charge of 96.2 %. That is outstanding, contemplating our automobile coated over 1,000 miles on this journey. All three carriers had respectable or good sign power for over 80% of the journey, which can also be actually good. AT&T’s and Verizon’s 5G protection each clocked in at over 35%, which is nice, however not significantly spectacular.

All three carriers had respectable or higher sign power for over 90% of the journey. That is additionally superb contemplating what I used to be anticipating. Essentially the most eye-popping metrics coming from this journey embrace Verizon’s velocity in Louisville, Ky, at slightly below 4GBps down.
As a aspect be aware, it looks like Verizon at all times has no less than one eye-popping outcome like that, so good for them. One other significantly fascinating stat is T-Cell’s 5G deployment. With numbers like that, it is easy to consider that T-Cell might need what it calls the “best nationwide 5G network”.
My verdict
All the identical, it is important to do not forget that I performed these exams whereas driving on Interstates, that are sometimes congestion-heavy zones. It is value repeating, if I had been going to construct a community, I might most likely begin with Interstates. Should you street journey alongside nation roads (which will be the topic of an article sooner or later), then the story could be very completely different.
Nevertheless, I got down to take a look at 5G networks on a street journey, which usually includes touring alongside interstates and stopping at gasoline stations alongside the best way. Total, it is reassuring to see that every one three networks are constructing appropriately, and no matter the place you end up caught on the aspect of the street, there is a good likelihood you will have a powerful sufficient sign to name for assist.
