Most 5G is on towers you already know
There is no single 5G tower design. In the United States, most 5G runs on low-band and mid-band spectrum, and carriers add it to their existing sites rather than building new ones. So a 5G tower usually looks like a monopole, lattice tower or rooftop site that has been there for years, with one or more new antenna panels added near the top.
The new panels are the clue. Classic LTE panels are tall, narrow rectangles, often around 6 to 8 feet long and less than a foot wide. Mid-band 5G panels, used for C-band, 2.5 GHz and 3.45 GHz, are usually squarer and deeper. They contain a grid of small antenna elements, called massive MIMO, that steer beams toward individual phones. They often have the radio built into the back, so there is less separate equipment hanging behind them.
Millimetre-wave 5G: the small cell
Millimetre-wave 5G (24 GHz and up) carries very high speeds but travels only a block or two and is stopped by walls, trees and even rain. It needs many small transmitters close to users. These small cells are what most people picture as a "5G tower", and they rarely look like towers at all.
A typical millimetre-wave small cell is a box or cylinder, roughly the size of a backpack or smaller, mounted near the top of a streetlight, utility pole or purpose-built slim pole. There is usually an equipment cabinet lower on the same pole, and sometimes a small power meter. In dense downtowns, stadiums and airports you may see them every block or so.
How to tell the pieces apart
| What you see | Likely use |
|---|---|
| Long, thin vertical panels in groups of three, one per direction | 4G LTE, often also low-band 5G |
| Squarer, thicker panels beside the thin ones | Mid-band 5G (massive MIMO) |
| Small boxes stacked behind panels | Remote radio units feeding the panels |
| Box or cylinder on a streetlight or utility pole | Small cell, possibly millimetre-wave 5G |
| Round dish | Microwave backhaul link to another site, not a phone signal |
| Long vertical whip or thin pole antenna | Two-way radio, public safety or paging |
Disguised towers
Where zoning boards ask for it, towers are disguised. The best known is the monopine, a monopole dressed with artificial branches. There are also monopalms, flagpoles with antennas hidden inside, fake chimneys and church steeples, and rooftop screens painted to match a building. These can carry 5G the same way an open tower does; the antennas are simply hidden. In FCC records a monopine is often registered as a tree or a monopole.
Finding the 5G sites near you
Because the FCC licenses 5G spectrum by area, there is no public list of which sites carry it. The practical approach is to find the registered cell sites near you on our 5G towers page, then check your carrier's coverage map for 5G at your address. Walk or drive by the nearest site and look for the newer square panels. Small cells will not be in the list, because they are too short to need FCC registration.
Your phone also helps: the 5G, 5G UW, 5G UC or 5G+ icon tells you when you are on 5G and, for some carriers, on which kind. Carriers use those extra letters to mark their mid-band or millimetre-wave service.
Common misconceptions
- A tower with no visible change can still carry low-band 5G. It uses the same frequencies and often the same antennas as LTE.
- Not every box on a pole is 5G. Many are older 4G small cells, cable-TV amplifiers or utility smart-meter collectors.
- 5G antennas are not required to look different, and camouflage rules apply to them the same as to earlier antennas.
