Access & Last-Mile Networks

Backbones are the easy part. The hard engineering lives between your PoP and the subscriber: splitter budgets, sector loading, interference floors, CPE quality, and the pole-by-pole decisions nobody documents.

Most access networks in our markets were not designed — they accreted. A tower here, a splice closure there, whatever radio was in stock that month. It works at 300 subscribers. At 3,000 it produces nightly congestion, unexplainable outages, and support queues that eat margin.

Our practice covers both physical media honestly: fibre where density and payback justify the civils, fixed wireless where they don’t — and engineered handover between the two, because in African deployment practice the answer is almost always a hybrid.

Interference is the silent killer of wireless ISPs. It rarely takes a network down outright; it degrades modulation, inflates retransmissions, and shows up in your business as churn nobody can explain. Fixing it takes spectrum analysis, a frequency plan, and the discipline to enforce it — not bigger antennas.

We have done this work where it is hardest. For DSI (DATCO Service Internet) in Eastern DRC, we upgraded the RF and core network from Ubiquiti to carrier-grade Cambium Networks and Cisco equipment across licensed and unlicensed bands — ending the chronic interference-driven outages that had defined the network — and delivered the IP and RF plan for residential expansion, including VLAN segmentation and spectrum optimisation.

At SkyTrend Networks, a CAK-licensed NFP ISP in Kenya, we re-designed the fibre-optic and wireless network infrastructure and systems architecture for nationwide expansion. Our frequency-planning practice is grounded in formal Cambium training (2016) and twenty-plus years of operating networks where spectrum is contested and power is unreliable.

A frequency plan that lives in one engineer’s head is not a plan. We leave you with documented channel assignments, reuse maps, and change control.
