Satellite internet vs 4G fixed wireless: what the sky does that the mast can't

Both services promise internet without a cable, and they deliver it with opposite weaknesses: satellite fights physics (the speed of light is a service-level agreement you cannot negotiate) while fixed wireless fights geography (a mast, a line of sight, and every other household sharing it). Your house decides which weakness is survivable.

What the sky costs you

• Latency, honestly: geostationary satellite internet adds a delay measured in hundreds of milliseconds - usable for browsing, painful for anything real-time, and the "low latency" generation of constellations in low orbit cuts that to tens of milliseconds by being closer, not by magic. Video calls work; a competitive game never will, on either version.
• Weather: heavy rain attenuates the Ku-band signals these services ride, and the outage is not the dish failing - it is the rain being a wall. Fixed wireless suffers its own weather story - mast congestion during storms when everyone is indoors at once.
• Anything that counts your bits: satellite plans historically meter, cap or slow; constellations have moved toward flat allowances, but the fine print and the local reseller's pricing are the truth here, not this page - check the current terms before the hardware is on the roof.

What the mast costs you

Fixed wireless - a 4G/5G router with an external antenna port, or the carrier's home-broadband box - is only as good as the cell it can hear: the same tower your phone fights at 9pm, with your house's trees, buildings and distance in the way. The advantages are real: no dish to align on a roof, equipment from the carrier, and if you already have decent phone signal indoors the router inherits it. The dependency is also real: when the mast congests or its power fails, your neighbours' traffic is your traffic, and the mast's backup generator has its own fuel story.

The decision, as a table

• Rural compound, clear sky, no mast worth talking about: satellite - it is the only one of the two that works by definition.
• Suburb, good phone signal, light users: fixed wireless wins on price-per-usable-megabyte and you lose nothing you were using.
• Anything with video calls all day, banking, VPN work: the latency argument matters - low-orbit or fibre-to-the-street over both, geostationary only if nothing else reaches.
• The household that shares one connection with phones tethering and homework: whichever service has the plan whose allowance you cannot accidentally hit by Tuesday - the cap is the real boss of the Nigerian home network.

One line neither seller says

Both services are measured on the evening, on your own roof - the trial period and the router's admin page are your lab, and the desk's only firm recommendation is that you keep the service long enough to use it on a Friday night, because everything else is a Tuesday.
