Expanding Farm Network's wireless capabilities across new areas
Expanding Farm Network's wireless capabilities across new areas
I understand some of this from my workplace, but it's outside my department. I'm not an expert, so I'll share a few points to think about or questions to consider. First, do you truly require full property coverage with WiFi, or just the buildings? Your property is roughly 400 ft by 400 ft, which equals about 160,000 square feet or 15,000 square meters—an extensive space to manage client-side WiFi. The structures themselves make up around 25% of that area, making it a more feasible scope. For comparison, the TP-Link EAP225-Outdoor has a maximum range of about 300 m² or 3,200 ft². Using standard napkin calculations, you'd need around 50 units to cover the entire site. For this setup to function well, most would likely need wired connections to a central switch. Other AP options will face similar constraints. Typical outdoor APs usually advertise ranges from 1,500 m² to 5,000 m², so the key factor is the upper limit.
This setup offers a superior PTP WiFi solution that aligns with your expectations. Key points to keep in mind: elevation plays a significant role; assess building heights and potential anchor locations. Determine if the property has a flat surface or incline. If you can place one or two centrally positioned omnidirectional nodes, it will greatly ease the process. Otherwise, a 90-degree base station might suffice if elevations match. The more affordable 5 GHz and 2.4 GHz PTP systems lag behind the newer 60 GHz option not only in speed but also in frequency usage, making proper frequency management crucial. Carefully evaluate the advantages and disadvantages. As you mentioned, these configurations can be affected by power concerns. For instance, the Tarana 60 GHz antennas are known for lengthy startup times (3 to 20 minutes). Implementing UPS backups will mitigate this issue. Don’t overlook interference from trees or other obstacles, which can disrupt performance. Any mounting point must ensure stability; these systems demand exact alignment and are sensitive to wind movement. If the wind ceases, antennas should not revert to their initial positions and will need recalibration. That’s why fixed structures like buildings are generally better than towers for anchor points.
My final point of consideration would be related to Ethernet. Don’t overestimate the cost of installing Ethernet. Especially in a cost to benefit analysis. Direct burial cable costs $0.15 - $0.50 per ft depending on the standard used. With a maximum range of 328 ft / 100 m you could reach nearly all of your buildings or all if midway switches are used (this is better practice anyways). It will also require less long term maintenance. As far as burial costs go the biggest cost there is actually labor / time. I would guess that being on a farm either you or someone else there already has the tools and knowledge to run / bury cables. Additionally, you can reduce the amount of burial necessary by running above ground conduits along the buildings. If time is the concern just be aware that getting a multi-node PTP system properly aimed and calibrated it no easy feat either.
I wonder if mentioning constant Wi-Fi across the whole property was unnecessary. More focus should be on efficient internet distribution for other areas and managing camera recordings. Since cameras are likely to be added over time, a central DVR location will be needed until new buildings replace older structures like sheds and barns. The property layout is flat, offering mounting points of at least 16 feet. Starting from the roof, an existing TV antenna mount could provide around 32 feet of height. All installations would remain on solid building surfaces. I experimented with a sector antenna in the Ubiquiti design center; a 60-degree setup seems suitable for the coverage area they provided. Based on the GHz options I’ve seen, 5GHz appears adequate here, though I’m unsure. Ultimately, I feel flexible—any solution can be tested later with the right software. Digging cables or using heavy tools isn’t cost-effective for me. When the ISP installed fiber, I had to use a tractor and a specialized digging machine through a tough packed driveway, uncovering hidden concrete beneath gravel. In the end, wireless seems like a more appealing and potentially cheaper choice. Also, since I don’t work on the farm full-time, my primary focus is off-site employment.
Consider having transmitters installed on each structure. WiFi devices won’t be able to send signals back. Connecting all buildings might not be financially sensible. I suggest a hybrid solution. It seems some structures are near, so linking them with a P2P bridge could be more efficient. Remember, you’ll probably need Ethernet for devices like cameras unless you’re planning wireless ones. Then you’ll have to manage power arrangements carefully. IP Ethernet cameras get powered through the same cable that carries data.
The main problem with 5 GHz antennas is overlapping frequencies with the 5 GHz client WiFi network. When many active 5 GHz connections are present, you usually need to limit your client APs to just the 2.4 GHz and 6 GHz bands for optimal performance. The 60 GHz band doesn’t face this conflict but comes with a higher cost, making it a trade-off between expense and benefit. It might be feasible to use one main base station combined with several directional antennas. Assuming PTP rather than simple mesh networking, a simple configuration would resemble this rough sketch.
Another important point is identifying your ISP type. If yours is a "Fixed Wireless" service, you'll need to work with them to avoid conflicts and might even be able to arrange the installation themselves. Occasionally, you can also become a tower owner, sharing the infrastructure with other nearby providers for lower costs.
I thought I’d need stations at each structure facing the main antenna or the access point—that’s acceptable. The existing outdoor WiFi setup would be upgraded with this new system. A hybrid method was also on my mind: a wireless bridge (PTMP), wired interiors, and wireless outside. This would work well for cameras in buildings over 200 feet long, especially where animals are present. I’d have power inside the buildings and could later install wireless cameras and devices there, one project at a time. The regular ISP likely wouldn’t support this, as they already use their own fiber line with locked router settings. Their network is housed in a steel building with double-lined panels, which should reduce interference from the new PTP network. Essentially, it would be a point-to-point solution delivering and splitting traffic. In simple terms, I’d operate my own WISP—my personal wireless internet service provider. The large companies cover vast rural areas, but I’m just focusing on my own needs. Since I don’t have neighbors close enough for interference concerns, I’m safe from their networks spilling over. If I had unlimited resources, I might even run Ethernet or fiber everywhere in conduits, but budget and time limits mean I’m trying to find practical options now. I feel confident it’s possible, but figuring out the cost-effective path is the challenge.
Fixed Wireless resembles your intended plan but operates as a service serving many customers. It's widely used in rural regions of the Midwestern and Southern United States. If you benefit from fiber to the home, you likely won't face interference issues.
