How to Get WiFi to a Granny Flat, Shearers' Quarters, or Second Dwelling on Your Property
A second dwelling on a rural property — whether it is a granny flat, shearers' quarters, a manager's cottage, or a converted outbuilding — creates a connectivity problem that most internet providers are not set up to solve.
The house has Starlink, NBN Fixed Wireless, or a 4G router. The second dwelling is 80 metres away, or 200 metres, or further — close enough that running a separate internet connection feels unnecessary, but far enough that the WiFi from the main house does not reach it reliably. The usual solutions are either expensive, complicated, or both.
This article covers why standard approaches fall short, and how TX-E Connect solves the problem without cable trenching, a second subscription, or a technician.
Why This Problem Is Harder Than It Looks
The obvious solution — just extend the WiFi from the main house — runs into a fundamental limitation of standard WiFi. A typical home router running 2.4 GHz WiFi has a reliable outdoor range of perhaps 50–100 metres under good conditions. Once you add building walls at either end, trees, sheds, or any significant distance, that range drops quickly. By the time you are trying to cover a granny flat 150 metres from the house, standard WiFi is simply not up to the task.
The common workarounds each have real problems:
A separate internet connection for the second dwelling is the most reliable option — but it means paying for two plans, two sets of hardware, and potentially two Starlink subscriptions. On a property where one internet connection is already more than adequate for the combined usage, this is a significant ongoing cost for a problem that is fundamentally about distance, not capacity.
WiFi extenders and repeaters operate on the same 2.4 GHz or 5 GHz frequencies as the main router. If those frequencies cannot travel the distance between the house and the second dwelling reliably — and across 100–200 metres of open ground with walls at each end, they typically cannot — an extender using the same bands faces the same limitation. Extenders also introduce latency and halve available bandwidth on the link between the router and the extended point.
Running ethernet cable is the most technically reliable option, but on a rural property it means trenching — digging a trench for conduit between the two buildings, running the cable, and backfilling. Across 100 metres or more of established lawn, garden, or hard ground, this is a significant cost and disruption. And once done, the cable is permanent — repositioning or extending coverage in the future means digging again.
Powerline adapters carry network traffic through your electrical wiring, which sounds ideal. In practice, performance degrades significantly if the two buildings are on separate electrical circuits — which is almost always the case on a rural property where the main house and a secondary dwelling each have their own meter board. Real-world speeds are usually a fraction of the headline figures on the packaging, and reliability can be inconsistent.
Why TX-E Connect Works Where Other Solutions Don't
TX-E Connect uses Wi-Fi HaLow (802.11ah), which operates at 900 MHz — a much lower frequency than standard 2.4 GHz or 5 GHz WiFi. Lower frequencies travel significantly further and penetrate obstacles more effectively. This is why AM radio reaches inside concrete buildings while 5 GHz WiFi does not; HaLow sits between the two on the spectrum and inherits much of that range advantage.
In practical terms, a TX-E Connect - Outdoor unit has a line-of-sight range of up to 1.5 km. On a property where the granny flat is 80 metres away, or even 300 metres away, that is well within a comfortable operating margin. The HaLow signal travels the distance between buildings without cable, without relying on the same frequencies that fail at range, and without requiring any infrastructure beyond a power outlet at each end.
The system works as follows:
At the main house: TX-E Connect - Outdoor is mounted at height — on a roof, a wall, or a pole — and connects wirelessly to your existing home internet (Starlink, NBN Fixed Wireless, a 4G router, or any other standard source). It rebroadcasts that connection as a long-range HaLow signal.
At the second dwelling: A second TX-E Connect unit — Indoor or Outdoor, depending on the situation — receives the HaLow signal and rebroadcasts it as standard 2.4 GHz WiFi. Any device in the second dwelling connects to this as it would any normal WiFi network. No special configuration, no specialist hardware.
Because the HaLow signal from the main unit covers the whole property, adding coverage to a second location does not require any changes to the first unit. If you later want to add coverage to a third location — a machinery shed, a workshop — you simply add another TX-E Connect unit there.
Choosing the Right TX-E Connect Unit for a Second Dwelling
For the main house unit, TX-E Connect - Outdoor is the right choice. Mounted at height and in an open position, it will broadcast the HaLow signal reliably across the distance to the second dwelling and beyond.
For the second dwelling, the choice between TX-E Connect - Indoor and TX-E Connect - Outdoor depends on the building and the distance:
TX-E Connect - Indoor is a good choice where the distance is moderate (under 200–300 metres in open conditions) and the unit can be placed near a window facing the main house. It is wall-mounted, powered by a standard outlet, and straightforward to set up.
TX-E Connect - Outdoor is the better choice for longer distances, when the second dwelling is a metal-clad shed or building with foil insulation, or when the unit needs to be mounted externally for best signal. Its improved outdoor HaLow antenna and weatherproof housing make it well-suited to exposed locations.
For metal-clad sheds and buildings with foil insulation — common on rural properties — placing a TX-E Connect - Indoor near a window, or mounting a TX-E Connect - Outdoor on the exterior wall, is the most reliable approach. See our article on getting signal inside a metal shed for more detail on this.
What TX-E Connect Delivers at the Second Dwelling
Once set up, the occupants of the second dwelling have a standard 2.4 GHz WiFi network to connect to — exactly as they would at the main house. Phones, tablets, laptops, and smart devices connect normally. Streaming, browsing, video calls, and messaging all work as expected.
One thing worth being clear about: TX-E Connect is not a speed product. The HaLow link between the two units delivers around 5–6 Mbps. For most second dwelling use — a resident browsing, streaming Netflix, making video calls, working from a laptop — this is more than adequate. It is not designed for high-throughput tasks like large file transfers or simultaneously streaming 4K content to multiple devices. If that is a requirement, a wired ethernet connection or a separate internet subscription is the right approach.
For the typical occupant of a granny flat, shearers' quarters, or managers' cottage, 5–6 Mbps of reliable connectivity is a meaningful practical improvement over no signal at all — and it arrives without a monthly subscription cost beyond the existing home internet plan.
Phone Calls and WiFi Calling
An important benefit of extending the home internet network to a second dwelling is that it restores full phone functionality for anyone living or working there who is in a mobile black spot.
If the second dwelling is in a location with no mobile coverage, a phone connected to the TX-E network can still make and receive calls using WiFi calling — a standard feature on modern smartphones that routes calls through a WiFi connection when mobile signal is absent. This works on the normal phone number, with no special apps or configuration needed, and includes calls to 000 emergency services.
For a granny flat housing an older family member, or shearers' quarters housing workers who need to stay reachable, this is a practical safety benefit beyond the convenience of internet access. See our article on emergency communication and property safety for more detail on WiFi calling and AML location sharing with emergency services.
Practical Setup Considerations
Line of sight helps, but is not always required. HaLow's 900 MHz frequency penetrates vegetation and some building materials better than standard WiFi. A clear line of sight between the two units is ideal, but moderate tree cover or an indirect path between buildings will not necessarily prevent the system from working. If in doubt, get in touch with the TX-E team to discuss your specific layout.
Height improves range. Mounting the TX-E Connect - Outdoor unit at the main house as high as practical — on a roof peak, above a verandah, or on a pole — maximises the coverage area and reduces the chance of obstacles interfering with the signal.
Power at the second dwelling. Both TX-E Connect units require a standard power outlet. At the second dwelling, this is almost always available — a granny flat, shearers' quarters, or managers' cottage will have power. If you need coverage at a remote location without mains power, TX-E Connect - Outdoor supports DC power input compatible with solar setups.
The network at the second dwelling is separate from the main house. Each TX-E Connect unit creates its own local 2.4 GHz WiFi network at its location. Devices at the second dwelling connect to the local network there; devices at the main house connect to the router's network there. The two networks share the same internet connection but are independent from each other — there is no shared local network between the two buildings. For most households this makes no practical difference. If you have specific requirements around shared local network access between the two dwellings, get in touch to discuss options.
Summary
Standard WiFi cannot reliably cover the distances between a main house and a second dwelling on a rural property. Extenders use the same frequencies that fail at range; cable trenching is disruptive and expensive; powerline adapters are unreliable across separate electrical circuits; a second internet subscription is a recurring cost for a problem that is fundamentally about distance.
TX-E Connect uses Wi-Fi HaLow (900 MHz), which travels significantly further than standard WiFi and penetrates obstacles more effectively — without cable runs or a second internet subscription.
TX-E Connect - Outdoor at the main house receives your existing internet connection and broadcasts a long-range HaLow signal. A second TX-E Connect unit at the second dwelling receives that signal and rebroadcasts standard 2.4 GHz WiFi for all devices there to connect to normally.
The HaLow link delivers around 5–6 Mbps — enough for streaming, browsing, video calls, and general internet use by the occupants of the second dwelling.
WiFi calling on connected phones works normally across the TX-E network, including calls to 000, which matters for second dwellings in mobile black spots.
Adding coverage to further locations — a machinery shed, a workshop — requires only an additional TX-E Connect unit at each location, with no changes to the main house unit.
