5G Coverage Meets the Laws of Physics

5G Wireless has been identified as the catalyst for everything from driverless cars to finding life on Mars.  What 5G needs to accomplish these miracles is lots of bandwidth.  The easiest way to get more bandwidth is to move up in frequency.  Unfortunately, the higher the frequency, the shorter the range, and the less the coverage. It's the law of physics, a law we can't break.  Coverage for the "low" cellular frequencies (600MHz, 700MHz, 800MHz) is measured in miles.  Coverage for the "high" cellular frequencies (24GHz, 28GHz, 32GHz) is measured in feet.

A well-located cell site could cover a radius of 5 to 30 miles with the lower and maybe mid-band (1 to 5GHz) frequencies.  But a site at, say, 28 GHz (2,800 MHz), would not cover even one mile from the cell site.  The tradeoff is that more bandwidth is available on the higher channels.


How do we overcome this frequency disadvantage?  The answer is getting more signal at the user's location, and that is most easily provided by an outdoor antenna, which limits us to getting the most from 5G at a fixed location.  There's nothing wrong with getting faster Internet access wirelessly at home, but of course, most of us would rather have it in our pocket wherever we travel.

T-Mobile plans to provide 5G Wireless on their new, low-band assignments at 600 Mhz.  Yes, there are bandwidth limitations there, so T-Mobile plans to let your wireless device access other, higher wireless channels where there is more bandwidth, if you're within the more restricted coverage area of those channels.  You see, you can't break the "law".

The other method of getting more 5G signal to more users is more cell sites...spaced about a mile or two apart.  Just look at all the fun in that!

Can We Trust Those Coverage Maps?

Last spring the Rural Wireless Association (RWA) cried fowl when the FCC released their unserved 4G LTE coverage map.  The RWA claimed Verizon Wireless and T-Mobile overstated their coverage in rural areas effectively preventing rural wireless carriers from securing federal funding to expand wireless coverage in rural areas from the Mobility Fund.  Recently, the FCC agreed to review the process to make sure.

PTCI Cellular, a small rural carrier complained that driving over their service territory of the panhandle of Oklahoma shows 85% of the area with no 4G-LTE coverage from any carrier, yet the FCC map showed the entire area covered.  Eyebrows were raised in several other locations, such as the state of Kansas, who noted that their state appears to have 100% 4G-LTE coverage on the map.  Kansas regulators are often fielding complaints about areas with no coverage, let alone at 4G-LTE quality.


We don't get complaints about coverage that shows on a map that doesn't appear in the real world, but we do get complaints about areas with coverage shown but unable to make reliable calls and access usable data.  The carriers involved claim that, if anything, their maps are conservative.  We also note that just because an area shows little 4G coverage, a carrier can offer 4G download rates with various combinations of RF technology.

We're hoping this results in better maps, but more likely, we may see maps that either show less coverage or less detail, just so the FCC, the RWA and other rural associations stop complaining.  Thank goodness they are.  We agree rural areas need better coverage and the rural carriers have the most incentive to provide it.  May the best map win.

Open Mobile Looks Closed

We could have predicted the demise of Open Mobile in Puerto Rico when they agreed to "share" their network with Sprint.  Today, Open Mobile doesn't actually say they have given up the business, but their stores are now all branded as Boost Mobile.  Since last year's hurricanes, wireless customers in Puerto Rico have suffered from spotty service and the carriers suffered from a reduction to their income stream.  Sprint can survive this but Open Mobile can't.


This may have been a decision made before the storms but the result is that the network will work better under a major player.  As usual, we hate to see another carrier bite the dust, but if you live on the island, you should be glad the way things turned out..at least for your wireless service.

When 5G Isn't Quite 5G

Verizon Wireless was the first to start with what they call "5G", but it's really only a step closer.  Verizon's 5G, called "Home", is actually a slowed-down version of their ultimate high-speed Internet service.  In order to win the 5G footrace, Verizon is offering fixed wireless equipment that does not use the universally-accepted technology (3GPP), and they do not yet offer the near 5G speed standards, near 20Gbs.  Verizon does plan to pick up the speed and eventually offer the latest technology, but will need to replace customer equipment when it becomes available.

Similarly, AT&T doesn't yet offer a true 5G experience, instead, they call their high-er speed data, "5G Evolution."  That means that they're getting faster in some areas on their way to eventually offering real 5G performance.  AT&T also claims they will have 5G mobile coverage, soon.  So, there are some name games going on here.  We're trying to figure out how to respond, both on our 5G Coverage Map page, and on our new 5G web site, Mountain5G.com.

Sprint will eventually offer a faster data experience but they have numerous headwinds getting to that point.  T-Mobile, who has been able to expand new coverage across the country at a surprising rate, claims they will offer a hefty 5G product that will be available in several large markets soon, also available for mobile use.

Don't overlook the other 2 hurdles that must be crossed: 5G-capable devices, and that so much new wireless infrastructure is required,  with so many obstacles to building it.  We don't doubt that each of the major carriers will get there and the race to 5G does include many methods of getting us increased broadband downloads.  Enjoy the trip to fast...slowly.

What Does 5G Mean for You?

Here it comes! 5G wireless holds the promise of big and fast data, but what does it mean to the average Joe wireless user?  There are so many potential uses of this newest hot technology we'll need to prioritize.  To us, the most immediate promise is the availability of a real competitor to the established cable and DSL Internet providers.  Most cellular carriers will initially be offering 5G as a Fixed Wireless product, meant to be used in the home or office.  Get your box and you're online at super speeds.

The advocates of 5G claim it will revolutionize everything from cars to toothbrushes.  In order for that to happen, the carriers will need to add 5G to each and every cell site in the nation, and a bunch of new sites as well.  So, for the dream of the Internet of Things to be realized, there will be quite a bit of work to be done.  The short term dream is for us to enjoy the capabilities of that device we carry in our pocket to work faster and better, but that's pretty narrow thinking.  5G can be much more than that.


Verizon Wireless is already accepting signups for 5G if you live in Los Angeles, Sacramento, Houston and Indianapolis.  I'm now looking at the deposit I made for fiber to come to my neighborhood as maybe a bit premature.  The race is on and right now it looks like wireless will win.  We have established 2 web sites that help you navigate Interstate Highway 5G.  One is the 5G Wireless Coverage page on our Cellular Maps site, and a whole new web site that will help you decide when and how to sign up for 5G Wireless, Mountain 5G.

Net Neutrality or Kiss Your House Goodbye?

Verizon Wireless gets a thumbs down during the northern California wildfires. They denied a request to un-throttle firefighters' phones.  These firefighters had subscribed to an "Unlimited" plan. 

Verizon's Response: "Regardless of the plan emergency responders choose, we have a practice to remove data speed restrictions when contacted in emergency situations. We have done that many times, including for emergency personnel responding to these tragic fires. In this situation, we should have lifted the speed restriction when our customer reached out to us. This was a customer support mistake."

"Verizon Wireless' throttling of a fire department that uses its data services has been submitted as evidence in a lawsuit that seeks to reinstate federal net neutrality rules."

Breakaway Wireless Breaks Away in Utah

Breakaway Wireless, the aptly-named cellular service of the Manti Communications Company in Utah, has indeed broken away.  This ultra-small carrier leaves a small hole in the middle of the state and their few customers have few choices...all bad.


As wireless advocates, we hope they will continue to use their network for other uses such as wireless Internet service (they haven't told us what they're doing with the network).  Before their breakaway, Breakaway shared the facilities of the Rural Independent Network Alliance (RINA) which now puts that cooperative association in jeopardy as they approach the critical number of subscribers to keep their other associated networks operating.  This may also affect a small number of Sprint roamers...but it's a very small number.

NMobile in New Mexico Calls it Quits

NMobile, the renamed cellular arm of the LEACO Rural Telephone Cooperative of Hobbs, New Mexico has thrown the big switch.  Their cellular service has been discontinued and their customers were left to fend for themselves as of June 30, 2018.  Sadly, the old LEACO network was one of the best around but serving a very small population that probably preferred to go with the 'big boys.'


LEACO advertises that their Internet service offers "LTE Wireless Internet", which we guess is the new use of their old cellular network, but we can't find anyone there who can either confirm or deny it.
