The Challenge
The force operated a legacy TETRA P25 network that could not support the bandwidth requirements of modern policing: body-worn camera streaming (each BWC generates 4-8 Mbps), HD video from 1,100 patrol vehicles, and real-time AI suspect matching from 260+ CCTV cameras. TETRA's 28Kbps data rate was structurally incapable of carrying video. Radio blackouts in underground carparks, metro stations, and steel-frame buildings left officers in high-risk situations without communication. Data sovereignty required all traffic to remain on sovereign national infrastructure — public 5G was not viable.

Solutions Deployed
Sovereign 5G SA core hosted on government-controlled infrastructure — all MCPTT voice, video, and data traffic stays within national jurisdiction with no international peering for sensitive communications
MCPTT (3GPP TS 22.280) push-to-talk on QCI 65 — floor arbitration under 150ms, talkgroup management for 17,000 users across the force's operational hierarchy, pre-emptive floor control for incident commanders
Body camera 5G modems streaming 4K H.265 to command center on eMBB slice — 8Mbps sustained per officer, compressed to 2Mbps with H.265. Footage tagged with GPS, officer ID, and timestamp for chain-of-custody compliance
Neutral host DAS across 18 major malls, 6 metro stations, and 3 airport terminals — ensures indoor coverage for officers entering high-risk enclosed environments
