When LTE backup makes sense
Retail branches, bank agents, and construction site offices often need continuity more than raw speed. A 20 to 50 Mbps LTE link is enough for card terminals, light browsing, and VPN to head office.
Use LTE as primary only when no fixed line exists yet. Many Kenyan construction projects in Kiambu, Machakos, and coastal counties run on 4G for three to six months before fiber is pulled.
Router features to specify
Automatic failover switches traffic when the WAN port on fiber CPE goes down. Dual SIM models let you load Safaricom and Airtel for coverage overlap in rural corridors.
External antenna ports improve signal in metal buildings and basements. Confirm band support for local carriers: B3, B7, and B20 are common on Safaricom 4G in Kenya.
- Dual WAN or LTE plus Ethernet WAN
- Load balancing optional, failover required for backup
- IPsec or WireGuard VPN to cloud ERP or HO
- Local Wi-Fi for staff phones and scanners
SIM and data planning
Business data bundles avoid consumer fair use surprises. Register the SIM to the company name for M-Pesa top ups and support. Set a monthly cap alert with the carrier.
Mount the router high, near a window, or use outdoor LTE antennas on masts for remote CCTV sites. Poor placement is the main reason backup links underperform in testing.
Frequently asked questions
How fast is LTE backup in Nairobi?
Typical usable throughput is 15 to 80 Mbps down depending on tower load and indoor signal. Test at the exact install point before you promise SLA to a client.
