Where the network must grow — and where it must survive.
Every polling district in all 16 states & federal territories, scored on two lenses: EXTEND — people living in 4G holes, weighted by forward flood & landslide hazard — and HARDEN — served districts whose towers face the highest climate stress. One method, national scale, fully reproducible.

967 of 1,743 gap districts and 1.53M of 2.15M underserved people are in Sabah & Sarawak — measured by area, weighted by real census population.
Incident history is blind exactly where it matters
Recorded incidents give Sarawak's gap districts almost no risk (3 of 547). Forward terrain + monsoon-rainfall hazard lifts that to 327 — without the forward layers, the highest-need half of the country reads as risk-free.
In Pahang, EXTEND and HARDEN are the same investment
34 gap districts are also incident-flood districts — coverage builds and flood hardening converge on the Kuantan belt, the same districts NADMA's Dec-2025 restore-first list ranks #1. See the war room →
