Three reasons the last mile stays dark.
No power
Grid electricity doesn't exist where connectivity is needed most. Signal Mesh runs on 20W solar with 48-hour LiFePO4 battery backup — fully off-grid, always on.
No infrastructure
Tower-based cellular costs $15,000–$80,000 per site. Signal Mesh deploys on any pole, rooftop, or tree in 20 minutes for $219 total — no contractor, no permit, no tower.
No affordable content
Mobile data costs 5–8% of daily rural income per GB in Liberia. Signal Mesh's onboard CDN delivers Wikipedia, health videos, education, news, and community media at zero data cost — always.
Not just connectivity —
a complete community media platform.
Every Signal Mesh node ships with 256GB of locally-served content across 8 categories. Loads in under 100ms. Works without internet.

From pole to network in 20 minutes.
Deploy
Mount the Signal Mesh on any pole, rooftop, or tree using the stainless steel clamp bracket. Aim the solar panel south. Done in 20 minutes, no tools required.
Connect
The node auto-configures its mesh network and connects to 4G LTE backhaul or Starlink. Up to 200 devices connect simultaneously within a 300–500m radius.
Earn
Local operators charge $1–3/month per subscriber. A 5-node village network serving 300 subscribers generates $600–$900/month — self-sustaining within 12 months.
Two counties. Five nodes. 2026.
The Signal Mesh pilot targets Bong and Nimba counties — densely populated rural districts with little to no fixed broadband and unreliable mobile coverage.
Pilot target: 5 nodes · 2 counties · 400–600 people connected · 12-month deployment
