Ten years in the past, the reply to the query of whether or not it is best to get fastened broadband or accept cell was easy: Yes, it is best to, so long as it’s technically potential and never outrageously costly. Mobile broadband was an emergency resolution for summer season cottages and homes in rural areas the place the fiber community didn’t attain, and a backup system for individuals who wanted fixed connectivity even when the common connection was down.
Today, each 4G and 5G networks have been rolled out and canopy giant elements of the nation. Operators promoting cell broadband promise speeds of as much as 1Gbit/s — greater than many fastened connections. Does this imply that you could simply as simply select cell broadband and ignore fiber?
We all know that cell networks have completely different protection in other places, and that speeds can fluctuate broadly. Sometimes you possibly can barely obtain emails in your cell phone, different occasions you possibly can stream movies and play quick on-line video games like Fortnite. How are you able to resolve for your self if cell broadband can meet your wants?
To reply this query, I’ve enlisted the assistance of researchers Anna Brunström, professor at Karlstad University, and Mikael Gidlund, professor at Mid Sweden University.
How it really works
Apart from the truth that each fastened fiber broadband and cell broadband can obtain bandwidths of a whole lot of megabits per second — and thus qualify as broadband — they’re two essentially completely different applied sciences.
The variations are essentially about the best way the applied sciences are constructed: Fiber carries mild via a bodily cable, whereas 5G makes use of radio and has to compete for area within the air. “A practical but often underestimated difference is that fiber is delivered directly into the house, while mobile broadband first has to get through the outer walls before the router even makes contact,” says Mikael Gidlund.

Anna Brunström says that fiber usually offers extra secure speeds and extra even latency (delay), as every buyer has their very own bodily connection. With cell broadband, all customers share the entire capability of the cell community. Therefore, cell broadband is extra affected by location, time, and cargo.
Another distinction is that cell broadband usually makes use of one thing referred to as Carrier-Grade NAT, a function that permits many subscribers to share a number of public IPv4 addresses. Instead of your router getting a novel public deal with, it’s usually given a non-public deal with, whereas fiber packages usually present public addressing straight. This is essential if you wish to arrange a server at dwelling, for instance. Mobile broadband, however, is extra versatile and transportable. It’s simple to get began and you’ll usually take the subscription with you to completely different areas.
Mikael Gidlund summarizes the variations between fastened and cell broadband as follows:
| Parameter | Fixed fiber connection | Mobile broadband (4G/5G) |
| Stability | Very excessive and predictable. Capacity is in observe devoted. | Variable as capability is shared by all customers in the identical cell. Walls, load and distance have an effect on. |
| Downloading | Stable excessive speeds even in heavy native use. | Can be very excessive in good protection, however drops when many individuals use the cell on the similar time. |
| Charging | Often symmetric or near symmetric — essential for work, AI technology, cloud providers, backup. | Significantly decrease than the obtain and closely affected by load. |
| Latency | Consistently low and easy. For video games and real-time providers. | Higher and extra variable. Affected by sign power, load and distance. |
| Flexibility | Fixed resolution tied to the deal with. | Very versatile — may be taken, moved, and utilized in a number of areas. |
Could cell broadband be higher?
At addresses the place fiber just isn’t already deployed, the simplicity of cell broadband could trump the technical benefits of fastened connection. The price can be considerably decrease in conditions the place you would need to bear the price of digging and laying the fiber cable to the home your self.
Mobile broadband can also be simple to take with you or activate at a brand new deal with, which makes it handy and may be cost-effective if you wish to use one subscription in a number of areas, equivalent to your private home and your trip dwelling or camper van. For many customers, cell broadband is absolutely able to assembly their wants, though speeds and latency can fluctuate greater than fiber. In locations the place fiber just isn’t accessible, cell broadband can even present a considerably higher person expertise than fastened broadband based mostly on older applied sciences equivalent to ADSL,” says Anna Brunström.

Mikael Gidlund additionally factors to flexibility as a significant benefit of cell broadband, saying that customers who primarily obtain (for instance, browsing and streaming movies) is not going to discover the cell community’s extra restricted add velocity as a lot as those that, for instance, play video games or are on video calls.
How are you able to resolve what’s proper to your scenario?
With fiber, it’s actually solely the worth and the web operator’s customer support that have an effect on how properly the connection works. When you select a subscription, you possibly can mainly rely on getting the promised velocity, and it’ll usually not fluctuate considerably.
With cell broadband, it’s a lot trickier and the scenario may be fully completely different even for 2 neighbors.
Always begin by occupied with your family wants. How dependent are you on a secure connection always? What sort of providers do you employ and what number of simultaneous customers are you able to count on? Is it principally downloads or do you additionally must add giant quantities of information? If you want a public IP deal with, verify that it’s potential to get one for the subscription you’re contemplating,” says Anna Brunström.
Mikael Gidlund says that the efficiency you’re going to get with cell broadband will depend on elements such because the surroundings, load, the operator’s community you select, and the kind of building the home is constructed with. He recommends that anybody pondering of selecting cell broadband ought to take a look at 4 issues:
1. How properly the community works the place you reside
It isn’t potential to check a subscription prematurely, however you possibly can nonetheless get a comparatively dependable thought of how the connection will behave. The most sensible approach is to make use of a cell phone from the identical operator you intend to make use of and perform assessments the place the router will likely be positioned. It is essential to measure at completely different occasions of the day, particularly within the night when the load is generally highest,” says Mikael Gidlund.
Speed assessments equivalent to Fast.com work properly for this function, whereas protection maps ought to solely be seen as a tough information and are sometimes over-optimistic.
2. How the home is constructed
Mikael Gidlund says the fabric of the outer partitions has a huge impact on the velocity of the cell community inside the home. Many new homes have home windows with vitality glass lined by a metallic movie, which significantly attenuates the sign power.
This is a technical drawback that doesn’t rely on the operator, however on the legal guidelines of physics: The larger the frequency, the tougher it’s for the sign to penetrate supplies. The quickest 5G networks use these larger frequencies.
One strategy to get spherical the home design is to get an exterior antenna. In addition to being positioned outside the place the sign is stronger, it may be directional and have sign boosters. In some circumstances, this can be the one strategy to get a passable cell broadband velocity.
3. Choice of operator
The rollout of 4G and 5G is way from evenly distributed. Larger cities usually have good 5G protection. But in smaller communities and sparsely populated areas, 4G nonetheless offers probably the most sensible protection, and 5G is probably not accessible in any respect or could solely attain sure elements of the locality. Differences between operators are important. It just isn’t unusual for one operator to carry out excellently in a specific location, whereas one other performs considerably worse regardless of comparable protection maps. Therefore, the selection of operator ought to be thought-about no less than as essential as the selection between fiber and cell broadband,” says Mikael Gidlund.
4. How many individuals share the capability?
All customers linked to a given cell (i.e. a cell mast) should share its complete capability. The extra customers and the extra they attempt to do, the much less capability there’s for every person. This is especially noticeable within the evenings when many individuals are streaming movies, if there’s an occasion happening within the space in order that extra individuals than typical are current, in locations the place unusually many individuals are utilizing cell broadband as a substitute of fastened, and in giant residence blocks.
In different phrases, if you happen to’re alone in a rustic home that occurs to be near a cell tower, have few neighbors, and primarily use the web in the course of the day, you’re more likely to get a a lot better expertise than if you happen to primarily wish to watch Netflix within the evenings and stay in a big residence block.
Are ‘unlimited’ cell broadband plans actually limitless?
Anna Brunström says that the majority limitless plans will likely be perceived as limitless in regular use. But there are limits you possibly can hit. For instance, cell broadband doesn’t usually embody roaming the nation.
There are additionally usually clauses within the contract that restrict irregular use. If you “hit the cap” in your subscription, you usually get a decreased velocity till the interval is reset or the chance to high up. Always learn the small print.
Mikael Gidlund says that operators usually have guidelines for so-called “fair use.” Those who use loads of information in a short while could have their velocity decreased, both briefly throughout peak durations or till the top of the cost interval.
A 3rd choice
Anna Brunström factors out that fiber and cell networks will not be the one applied sciences accessible to get an web connection. Another choice that has turn into viable in recent times is satellite tv for pc web.
The commonest client options, equivalent to Starlink, depend on satellites orbiting near the Earth with typical speeds round 50-200Mbit/s and latency round 20-50ms, which is adequate for streaming, video conferencing, and on a regular basis shopping. On the optimistic facet, cell broadband and satellite tv for pc are additionally complementary, as satellite tv for pc can work much less properly in densely populated areas the place there’s normally good cell protection. Areas with poorer cell protection usually work properly with satellite tv for pc.
