Germany’s Gigabit Strategy: Balancing FTTH Fiber Rollout with Fixed Wireless

Policy goals are not site availability

Germany’s 2022 Gigabit Strategy sets a direction toward nationwide fibre and the latest mobile technologies by 2030, as summarised by the European Commission. A national objective is not a binding activation date for a factory, farm or household. For an individual address, separate a planned route, a passed building, an installed drop and an active service. These milestones require different civil works and commercial commitments.

FTTH brings fibre to the premises; FTTB may leave a different in-building distribution medium. A Mittelstand procurement should specify the actual demarcation, internal riser work, symmetric bandwidth requirement, handover interface and restoration terms rather than buying the word gigabit.

Where fixed wireless fits

Fixed wireless can bridge a construction delay if there is usable radio coverage and sector capacity. Indoor signal bars are insufficient evidence. Survey outdoor placement, line of sight where relevant, busy-hour throughput and seasonal vegetation. The radio access network still needs backhaul and power; adding a wireless backup does not guarantee independence from the same fibre route that serves the primary connection.

A household prioritising streaming may tolerate evening variation. A manufacturer sending machine images to an external quality-control service should measure sustained upload performance and interruption duration. The same advertised download tier can support these workloads very differently.

Stage the rollout

Install a router that can accept both the temporary WAN and the future optical handoff. Keep LAN addressing and local services stable during the change. Document cancellation periods, installation charges and equipment ownership. Put long-lived production dependencies behind an application or VPN design that tolerates WAN address changes.

Verify the final service

After fibre activation, test wired throughput in both directions, the actual VPN overhead and backup behaviour. Retain wireless only if its independent failure path and recurring cost justify it. Archive commissioning records and update the asset register; a temporary connection that quietly becomes permanent is a common source of unclear support ownership.

From concept to acceptance

Worked design exercise

A workshop expects fibre in nine months and currently sends 40 GB of production data each workday. At a sustained 10 Mbps upload, an ideal transfer takes about 8.9 hours; at 50 Mbps it takes about 1.8 hours. A fixed-wireless plan with an attractive download rate can therefore remain unsuitable if its upload or busy-hour behaviour is weak.

Set a written interim-service review date, measure successful daily transfer completion and retain the fibre installation milestones. When the fibre service activates, compare the same workload through the same firewall so that the before-and-after result is meaningful.
