Comparing connection types
Fiber, cable, fixed wireless, DSL and 5G side by side on speed, reliability, cost and install time.
Which type of business internet connection is best?
Fiber is the best connection where it reaches: the highest speeds, symmetrical upload and the lowest latency. Cable is the usual second choice and costs less. Fixed wireless and 5G work where no wire is available. DSL is being retired. Availability at the address decides more than preference does.
The full comparison
| Type | Typical speed | Upload | Latency | Install time |
|---|---|---|---|---|
| Fiber | 300 Mbps – 10 Gbps | Often symmetrical | 1 – 10 ms | Days where the building is already lit; commonly 60 – 90 days or more where it is not |
| Cable | 300 Mbps – 2 Gbps | 10 – 50 Mbps, higher on upgraded networks | 10 – 30 ms | Usually within a week or two |
| Fixed wireless | 100 – 500 Mbps | 20 – 100 Mbps | 10 – 40 ms | 1 – 3 weeks |
| 5G / cellular | 50 – 400 Mbps | 10 – 100 Mbps | 20 – 60 ms | Days |
| DSL | 10 – 100 Mbps | 1 – 10 Mbps | 20 – 60 ms | Days, where still sold |
| Satellite, low-earth orbit | 50 – 300 Mbps | 5 – 25 Mbps | 25 – 60 ms | Days |
| Satellite, geostationary | 25 – 100 Mbps | 3 – 10 Mbps | 500 ms and up | Days |
Strengths and trade-offs
| Type | Best for | Trade-off |
|---|---|---|
| Fiber | Anything serious — phones, backups, hosted services, heavy video | Not available everywhere; install can require construction |
| Cable | General office work at the lowest cost per megabit | Shared capacity and weak upload |
| Fixed wireless | Backup, or primary where no wire reaches | Needs line of sight; some bands are weather sensitive |
| 5G / cellular | Failover, pop-up sites, retail, temporary offices | Data caps and variable indoor signal |
| DSL | Very small sites with nothing else available | Slow, asymmetric, and being withdrawn as providers retire copper |
| Satellite | Remote locations with no terrestrial option | Low-earth-orbit services now carry voice and remote desktop acceptably; older geostationary services do not |
Suitability by workload
| If your office mainly does this | Reasonable choice |
|---|---|
| Email, web apps, occasional video calls | Cable or fiber broadband |
| Phones over the internet, all day | Fiber, or anything with low jitter and steady upload |
| Large uploads, backups, media files | Symmetrical fiber |
| Hosting something reachable from outside | Dedicated internet with static addressing |
| Keeping a site online through a primary failure | A second connection on a different medium |
How to narrow it down
Find out what actually reaches the address
Coverage varies street by street.
Set your upload floor
Count simultaneous calls and any backup that runs in office hours, then add headroom.
Decide if you need a commitment
If downtime costs real money, look for a committed rate and an uptime figure rather than a bigger headline speed.
Compare the total, not the monthly
Setup fee, term length, equipment charges and the post-promotional rate all belong in the comparison.
Speeds, pricing and availability differ by provider and by address, and the figures in this article are general market ranges rather than an offer. For the decision itself, see which connection type; for the vocabulary, see internet terms explained.
