Fixed wireless access

Also known as: FWA, fixed wireless, wireless WAN

Fixed wireless access (FWA) uses a mobile network as a fixed location's primary internet connection, in place of a wired circuit.

How it works

A stationary router with a cellular radio and often an external antenna connects to a nearby cell site and serves the premises like a wired circuit would, providing routing, NAT, and local networking behind it.

Why it matters

FWA can be provisioned in days rather than the weeks or months a wired install takes, which makes it viable both as a primary connection where wireline options are poor and as a bridge while a wired circuit is being delivered.

Common use cases

Sites where wired broadband is unavailable or uneconomic
Temporary and rapidly deployed locations
Bridging connectivity while a wired circuit is provisioned

The practical appeal is lead time. A wireless circuit can be live in days, which is often the deciding factor rather than raw throughput.

Where the lead-time advantage does and does not hold

Fast provisioning is real, but it is a property of the circuit rather than the project. Two things still take time and are worth sequencing early.

The site survey. Signal has to be adequate where the equipment will actually be installed, and confirming that requires someone on site with a meter. Sites that look fine on a coverage map can be marginal indoors, and the fix — an external antenna, a different mounting location — has its own lead time.

Anything that touches an inside wire path. If the replacement has to reach endpoints distributed through a building, the constraint becomes the existing cabling rather than the circuit.

Where FWA is being used as a primary connection rather than a backup, evaluate it against the same criteria as any primary: what the throughput is at the busy hour rather than at installation, what the data allowance is, what happens when it is exceeded, and what the recourse is when the site’s performance degrades because the sector serving it got busier.

Common misconceptions

“Fixed wireless access and internet failover are the same thing.”

FWA is the primary connection; failover is a backup that activates when a primary fails. The same hardware can often do either, but they are different roles.

Frequently asked questions

Is FWA fast enough to be a primary connection?

For many business workloads yes, though throughput depends on radio conditions, spectrum, and cell loading at the location. Assess signal at the specific site rather than relying on coverage maps.
