HK Broadband Map

HK Broadband Map provides a comprehensive view of broadband internet coverage across all buildings in Hong Kong. Compare ISP availability, speeds, and technologies at the building level.

Data Sources

Building Database: HK Government Address Lookup Service (ALS) — provides canonical building addresses with coordinates
Building Names: Rating and Valuation Department (RVD) — comprehensive bilingual building names
Fibre Coverage: OFCA Building Fibre Register — buildings with optical fibre access
ISP Plans: Individual ISP coverage checkers — HKBN, PCCW/Netvigator, HGC, SmarTone, CMHK, i-Cable

How Address Matching Works

Each ISP uses different address formats. We normalize addresses using a multi-pass algorithm:

Exact match on normalized building name
Fuzzy matching using Levenshtein distance (threshold: 85%)
Street + number matching within the same district
Verification via the HK Government ALS API

Low-confidence matches are flagged with a warning indicator. We continuously improve matching accuracy as we collect more data.

ISPs Covered

HKBN (香港寬頻) — Residential fibre broadband
PCCW/Netvigator (網上行) — HKT's residential broadband
HGC (和記環球電訊) — Fibre and DSL services
SmarTone (數碼通) — Fibre broadband in designated buildings
CMHK (中國移動香港) — Home broadband services
i-Cable (有線寬頻) — HFC network broadband

Limitations

Coverage data is scraped from ISP websites and may not reflect real-time availability
Some newly constructed buildings may not appear in the database
Pricing information may be outdated — always verify with the ISP
Address matching is not 100% accurate for all buildings

Open Source
