Broadband in Public Housing: How Is It Different?

Around one-third of Hong Kong's population lives in public housing estates managed by the Hong Kong Housing Authority (HA). However, choosing broadband in public housing comes with unique challenges that differ significantly from private residential developments. From infrastructure planning and ISP approval processes to technology deployment methods, everything is managed differently under the HA's centralised oversight. This guide covers everything public housing residents need to know — from infrastructure and coverage to pricing and practical tips.

Public Housing Infrastructure: FTTB Is the Norm

Understanding the fibre technology deployed in your building is the first step to making an informed broadband choice.

FTTH vs FTTB: Why Is FTTB So Common in Public Housing?

There are two primary fibre deployment methods in Hong Kong:

• FTTH (Fibre to the Home): Fibre optic cables run directly into your flat, delivering the most stable speeds and easily supporting 1000M or even 2.5G connections
• FTTB (Fibre to the Building): Fibre runs only to the building's telecom room, with the final connection to your unit using copper wiring (telephone lines or coaxial cable)

FTTB is the dominant technology in public housing for several key reasons:

• The sheer number of public housing blocks makes full FTTH deployment prohibitively expensive
• Older estates have limited internal conduit space, making it difficult to run new fibre cables
• The Housing Authority must approve all cabling works, adding time to the process
• ISPs see lower return on investment in public housing, reducing their incentive to upgrade

The practical impact for residents: maximum speeds are typically capped at 100M to 500M, and fewer public housing units can access 1000M or higher plans. However, some newly built or recently renovated estates now offer FTTH coverage.

Which ISPs Cover Your Estate?

Public housing generally has fewer ISP options than private developments, but the major providers still maintain reasonable coverage. Here is an overview:

Important: Coverage can vary between different blocks within the same estate. Always check on a per-block basis.

How to Check Coverage at Your Estate

1. Use FibreHK to enter your estate and block address for a one-stop check across all providers
2. Call individual ISP hotlines directly (HKT: 183 3833, HKBN: 128, HGC: 1220)
3. Ask your estate office for a list of ISPs that have entered the estate

Port Exhaustion Is Worse in Public Housing

Port exhaustion — known locally as "爆Port" — is one of the most common broadband issues for public housing residents. The high resident density combined with limited equipment capacity means port shortages are significantly more prevalent than in private developments.

Why Are Public Housing Estates More Prone to Port Exhaustion?

• Extremely high unit density: A single public housing block can contain hundreds of units, while a typical switch only has 24-48 ports
• Fewer ISP options: Estates served by only 2-3 providers run out of ports faster
• Ghost port problem: Residents who transfer out without cancelling their service leave ports occupied but unused
• Slow expansion approvals: Capacity upgrades require Housing Authority approval, which takes longer than in private estates

What to Do If Ports Are Exhausted

1. Register with multiple ISPs simultaneously: Provider A being full does not mean Provider B is too — casting a wider net increases your chances
2. Consider 5G Home Broadband: Not affected by port limitations, plug-and-play setup, typically HK$98-198/month
3. Report through your estate office: Gather neighbour support and request that the provider install additional equipment
4. Monitor expansion announcements: ISPs periodically assess and expand capacity — stay informed through estate notices

The Housing Authority's Role in Broadband

The HA plays a central role in broadband provision across public housing estates:

ISP Entry Process

For a broadband provider to offer service in a public housing estate, they must go through the HA's approval process:

1. The ISP applies to the HA for permission to enter the estate
2. The HA evaluates technical feasibility and telecom room space
3. An entry agreement is signed covering fees, equipment placement, and other terms
4. The ISP installs equipment and runs cabling
5. Service becomes available to residents

This process can take 3-6 months or longer, which partly explains why some estates have limited ISP options.

What the Housing Authority Controls

• Telecom room allocation: Determines how much space each provider can use
• Cabling standards: Sets rules for cable routing and installation standards
• Fee oversight: Ensures providers charge residents reasonable rates
• Dispute resolution: Handles complaints between providers and residents

Public Housing Broadband Pricing: Generally Cheaper

The good news is that broadband in public housing is typically more affordable than in private developments. The main reason is volume — with a large potential customer base, ISPs can offer lower per-unit pricing. Here are reference prices for 2026:

Prices shown are reference monthly fees for 24-month contracts. Actual pricing varies by estate and provider.

Public Housing Exclusive Offers

Several ISPs run special plans specifically for public housing residents:

• HKBN Public Housing Plans: Extra monthly discounts for designated estates, with 100M starting from just HK$78/month
• CMHK Estate Offers: Half-price for the first 6 months at selected estates
• HKT Public Housing Bundles: Combined fixed-line and broadband packages from HK$88/month
• HGC "Estate Net" Plans: Entry-level broadband designed for public housing, starting at HK$88/month

Choosing the Right Speed for Your Public Housing Flat

Public housing flats are generally compact (typically 200-500 sq ft), and FTTB technology imposes certain speed limitations. Use this guide to choose the right plan:

For most public housing families, 200M-500M offers the best value for money and comfortably handles everyday needs. A 100M plan is perfectly adequate for 1-2 person households or light users.

Estate-Specific Tips: Read Before You Sign Up

1. Arrange Broadband Before Moving In

If you have just been allocated a public housing unit, start checking broadband options 2-4 weeks before your move-in date. Larger new estates often have ISP representatives on-site during the move-in period, giving you the chance to compare offers face to face.

2. Watch for Upgrades During Estate Renovations

The Housing Authority periodically carries out major repairs and renovations on older estates. During these works, telecommunications infrastructure may also be upgraded. Keep an eye on estate notices to find out whether new ISPs are entering the estate or speed upgrades are becoming available.

3. Use Your Estate Office as a Resource

Estate management offices can provide information on which ISPs serve the estate, technical specifications, and complaint channels for broadband issues. When in doubt, start by asking the office.

4. Pay Attention to Contract Terms

• Public housing residents may need to transfer to a different estate due to policy reasons. Before signing, confirm whether the contract allows penalty-free cancellation in the event of a transfer
• Some ISPs offer shorter contract terms for public housing (12 months vs the standard 24 months), providing greater flexibility
• Most providers waive or reduce installation fees for public housing units

5. WiFi Router Placement Tips

While public housing flats are compact, the concrete wall construction can significantly weaken WiFi signals. Recommendations:

• Place your router in a central location within the flat
• Avoid positioning it next to your TV or microwave oven
• A mesh router system is usually unnecessary for public housing units — a single good-quality WiFi 6 router is sufficient
• If the ISP provides a free router, try it first before deciding whether to buy your own

Reference: Broadband at Major Public Housing Estates

Below is a snapshot of broadband coverage at selected large public housing estates (for reference only — always verify with an actual coverage check):

Coverage and speeds may vary by block and over time. Always verify with a current coverage check.

Summary: Three Steps to Choosing Public Housing Broadband

1. Check coverage first: Use FibreHK to check which ISPs serve your specific estate and block, and what speeds are available
2. Compare pricing: Public housing typically enjoys discounted rates — do not settle for the first quote; compare multiple providers
3. Match your needs: Choose a speed tier based on your household size and usage habits. 200M-500M suits the majority of public housing families

While broadband in public housing has certain limitations, doing your research ensures you can still find a plan that offers excellent value for money.
