What Do 5G Symbols Mean on My Phone

In the past, we’ve discussed the technical factors surrounding 5G, such as frequency bands and the airwaves at which 5G operates (low, mid, and high). But what about the different terminology used by cellular providers and those 5G icons on your phone that indicate your cell phone’s signal strength? If you’ve wondered what those 5G, 5G Ultra Wideband, 5G Ultra Capacity, 5G Plus, and 5G C-Band symbols mean on your phone, you’re not alone. This is often a lot of confusion surrounding these 5G symbols. 5Gstore is here to explain exactly what they mean. Read on — this article will discuss the meaning behind 5G, 5GUW/UWB, 5GUC, and 5G C-Band symbols.

What is 5G?

When you hear 5G, you may think of the hype that surrounded its rollout in 2018, 2019, and 2020. Today, about 90% of America’s population has 5G available. Even if you’re in the 10% of the country that doesn’t yet offer 5G in your location, your smartphone is likely 5G-compatible and you have experienced 5G speeds in some capacity at a certain point.

The 5G signal strength is what providers like to call “5G Nationwide.” 5G is currently the most widely available service in America. Theoretically, 5G has the potential for 10 Gbps speeds; in reality 5G alone is similar to 4G LTE speeds. 5G service may provide you with enough speed to watch a high definition or 4K video; however, it may not be fast enough to handle multiple streams at the same time. 

What is 5G Ultra Wideband?

This is where 5G Ultra Wideband comes in. As Verizon’s highest-performing 5G, 5G Ultra Wideband (5G UW) can be up to 10x faster than 4G LTE. This makes it capable of handling multiple audio or video streams simultaneously. T-Mobile® and AT&T have similar 5G networks. T-Mobile calls this signal “Ultra Capacity,” or “5G UC.” AT&T calls it “5G Plus.”

What is C-Band?

You may also encounter “C-Band,” which is part of Verizon’s Ultra Wideband network. C-Band simply operates in a different section of 5G and is one of the newest types of 5G. It can be extremely fast and can support large amounts of data. C-Band is currently not widely available due to its limited range. 

5G Symbols

So what does that 5G symbol on your phone mean? 5G devices will display specific 5G icons connected to 5G Nationwide. These devices include those connected to Verizon, AT&T, and T-Mobile networks:

  • T-Mobile: T-Mobile’s Ultra Capacity network may display a “5G UC” symbol. A 5G icon without the “UC” indicates that you’re connected to a slower 5G network. This is what T-Mobile refers to as “Extended Range.” 
  • Verizon: Verizon will show 5G UW (or 5G UWB) when connected to 5G Ultra Wideband. C-Band does not have its own indicator, so it falls under 5G UW for Verizon (or 5G+ for AT&T). 
  • AT&T: AT&T icons may display “5GE,” which is actually 4G LTE. AT&T simply got creative with their advertising in 2020 and came out with “5G Evolution.” 5G Evolution is supposed to be faster than traditional LTE, but its speeds are not quite as fast as you might expect from 5G. Unfortunately, it still appears on some phones. 

What to Look For on Your Phone

Note that not all phones are alike. For that reason, how they display their network details might differ slightly. Take a look below at some common examples. 

5G: This is simply 5G service. This 5G icon applies to all providers.

5GE: 5G Evolution is 4G LTE on the AT&T network.

5G+: 5G Plus is AT&T’s faster 5G service, and includes C-Band.

5G UW/ UWB: 5G Ultra Wideband is Verizon’s fastest 5G service.

5G UC: 5G Ultra Capacity is T-Mobile’s fastest 5G service available.

Testing Verizon C-Band in New York City

Verizon’s new 5G network is live and PCMag just tested it out in New York City. In summary, C-Band made their connections about 50% faster, once they were able to find the signal. They also noted less congestion on the network, which is likely due to it still being so new. 

Starting this past Wednesday, Verizon launched its new form of 5G in 46 cities. AT&T did also, but only in eight cities. 

While PCMag reports the Verizon service being noticeably improved, it didn’t measure up to T-Mobile’s citywide “5G Ultra Capacity”— at least, not yet. T-Mobile currently has the most coverage in New York City and the best performance also in comparison to its competitors. 

Looking at reports from other cities, it seems that may not be the same as in New York City. Per PCMag’s report, “Redditors are busy posting spectacular C-Band speeds, including 859Mbps down in Los Angeles, 586Mbps outside Pittsburgh, and 413Mbps in Indianapolis.”

In order to test the C-Band, the PCMag team used the new Ookla WIND software. This is a carrier-grade package that runs on altered Samsung Galaxy S21+ phones. WIND’s Pro version, which the company supplied for testing, shows all the details of frequency band use you could ever need. It also lets testers build complex setups with voice, data, text, and video tests.

Verizon’s C-Band was a little hard to find during the New York tests. They ended up being able to use C-Band only on sites in two cities – Forest Hills and Kew Gardens. In other locations like East Harlem, their phone had refused to connect to C-Band, despite Ookla having identified the location as having C-Band available. It’s possible that some connections are being blocked by the carrier, or perhaps something to do with technical interference.

PCMag also addressed the “exclusion zones” that carriers agreed to with the FAA. Some of the exclusion zones are around JFK and LaGuardia airports. These are some of the busiest airports among a part of the city that is populated by about 2.3 million people. This is the same case for areas like Chicago, Dallas, and San Diego. Folks here unfortunately don’t have the benefits of the new 5G because of interference risks with aircraft altimeters

Per Verizon, the exclusion zones are a rectangle 2 miles long extending from the end of each airport runway. In one case during the tests, they were unable to find C-Band in an arc spanning from 4 miles southeast to 3 miles southwest of the end of the LaGuardia runway. That area covers many of Queens’ densest neighborhoods. Unexpectedly, though, they found more millimeter-wave in the exclusion zone than they expected to. 

“While the super-fast, short-range technology didn’t blanket the area, it kept popping up here and there throughout Long Island City, Astoria, Sunnyside, and Elmhurst, giving a huge boost when I could find it,” the article reads. 

They continued, “I can’t tell if Verizon’s avoidance of neighborhoods closer to LaGuardia is about the exclusion zone, or just the vagaries of early network buildouts. But we can confirm that while there’s no C-Band coverage within 2 miles of the airport, there is definitely coverage between 3-4 miles away.”

So just how fast is 5G? 

PCMag’s tests shows the in most cases, the C-Band service was double the speeds of LTE. This is because 5G was made more efficient and spread across multiple airwaves, making it able to provide more speed with less congestion on the networks. 

The article explained this more technically. “C-Band roughly doubles the airwaves Verizon had available for use in our tests. In most of our tests, Verizon used 40-50MHz of 4G LTE spectrum. When its “nationwide” 5G was active, it added 10MHz of low-band 5G to that. C-Band trades out that 10Hz of low-band 5G for 60MHz of mid-band, resulting in 100-110MHz being used.”

In comparison to tests run with T-Mobile, Verizon was just a little less. T-Mobile generally used 40MHz of 4G LTE along with 80MHz of mid-band 5G, for a total of 120MHz.

Tests were split between the carriers’ 4G and 5G components. PCMag found that in T-Mobile’s tests, 75% of the speed came from 5G, while in Verizon’s tests, 45-55% came from 5G. They also noticed that for some unknown reason, “each megahertz of Verizon’s was slower than a megahertz of T-Mobile’s—something the bigger carrier is surely working on optimizing.”

They also discovered something rather odd. “A bunch of our C-Band results in Kew Gardens all congregated around 140Mbps down in a way that makes me think it was a configuration issue or cap, not the capability of the network.”

What about the reach of the C-Band service?

The tests performed by the PCMag team have already shown T-Mobile is faster than Verizon on their mid-band spectrums – T-Mobile at its 2.5GHz frequency and Verizon at the higher C-Band spectrum.   The real question now is, which carrier delivers more range? PCMag says, “But the fact is, urban networks in places like New York, Chicago, and Dallas are dense enough that the difference may not matter.”

The case in Queens, for example, Verizon’s network is so dense that sites don’t have to broadcast very high to be received. It’s the same for T-Mobile here, whose extremely dense network in Queens has sites that are often a quarter-mile from each other or less.

From their findings, PCMag believes the jury is still out in the battle of mid-band distance. Though it is clear that C-Band has enough reach so that carriers won’t need to put a site every few blocks. 

Do I need C-Band now?While C-Band is available now, it can only get better as Verizon continues to roll out service. “In many other cities, it appears to already be better; my experience in Queens looks like the low end of the C-Band experience,” said the author of the article. They added, “The C-Band boost will come primarily to places within half a mile to a mile of a Verizon cell site, so look up your location on cellmapper.net if you’re curious. It’ll also require a recent phone.”
