LigoWave Wireless Solutions for Fish Farms

How Fish Farms Benefit from Wireless Networks?

Wireless networks allow farms to centralize farming operations, this way ensuring faster, safer, easier, and more efficient work:

• gain direct access to data from various sensors installed in the fish cages;
• observe underwater activity in the fish cages using IP cameras;
• oversee above-water operations and keep the premises safe. Security camera footage can be sent to a local surveillance room or relayed to a security agency that guards the farms;
• control the feeding systems and other farm equipment from a remote computer.

Also, fish farms are often located in remote areas that do not have fixed broadband. A wireless network would help facilitate the introduction of internet access to the territory, in turn allowing fish farms to benefit from an onsite administrative office that is connected to the rest of the world.

Finally, wireless networks provide the framework necessary for communication. Fish farms can take advantage of localized voice services that would allow the central office, farming sites, and feeding barge to communicate with each other.

How Do Wireless Networks Work in Fish Farms?

A typical fish farm includes a land-based central operations office and one or more offshore farming sites reachable by an ocean boat. The topology may vary depending on the specific fish farm requirements, but the most likely architecture in this case would be the following:

The central operations office houses the main IT-infrastructure that is used for fish farm systems control and video surveillance stream playback. Other equipment such as a network video recorder and voice service devices would also be included here.

In most cases, fish farms are built in areas that do not have fixed broadband. Hence, it is necessary to build a wireless trunk link with the nearest internet network—this is where the wireless outdoor bridge comes into play.

The base station is deployed facing the farming sites on a pole near the central operations office. It communicates wirelessly with the client devices found on each of the farming sites.

The onsite wireless client devices are connected to local switches using cables. These switches route the various traffic to and from the devices around the farm:

• one-way data streams coming in from the under/above-water sensors and surveillance cameras, which are connected using underwater and outdoor Ethernet cables;
• two-way communication with the onsite systems and voice services equipment using regular Ethernet cables.

Fish farm infrastructure may vary depending on the needs and requirements:

Feeding barges may be equipped with wireless client devices, this way extending internet access and voice services to the ocean boats, as well as enabling wireless communication with the sensory systems on the fish cages. Depending on the distance between the sites and the central base station, additional wireless devices may need to be installed on the farming sites to ensure the feeding barges are always within the coverage area.

Fish farms have the option of running optical fiber along with the underwater electrical cables that power the farming sites. However, this is the more expensive solution, the cost of which generally does not justify the benefit. Wireless solutions, on the other hand, are proven to provide not only cost-efficiency, but also flexibility and the necessary performance in enabling communication.

Depending on the layout and distribution of the sites, multiple central base stations may be required to cover the entire fish farm area.

How Can LigoWave Help with Your Wireless Fish Farm Network?

Ocean-based fish farms are subject to a number of risk factors, including strong tides, high winds, direct sunlight, as well as highly humid & salty environments. LigoWave offers wireless network solutions made to withstand the intense conditions found in fish farms, without compromise to performance and practicality:

IP-Rated Casing.

All LigoWave outdoor wireless devices are housed
in IP65/66 plastic or IP67 metal enclosures. The level
of ingress protection ensures ample waterproofing
against rainstorms, high tides, and other weather
conditions. The housing itself is made of non-
corrosive materials, allowing for extensive use in
humid environments. Also, the IP-rated casing
does not turn yellow over time due to prolonged
exposure to direct sunlight.

Small Form Factor.

Much of LigoWave’s next-gen hardware is designed
to have a reduced physical footprint, making the
wireless devices compact and light. This means that
the devices are easier to deploy in places where
space is limited and are significantly less affected
by strong winds, reducing the chances of it being
broken off its mounting.

Surge Protection.

LigoDLB is one of very few outdoor wireless
networking device series of its kind that is equipped
with integrated surge protection. LigoWave offers
a 2kV line to-line and 4kV line-to-ground safeguard
against current spikes and surges caused by extreme
environmental factors, while most other vendors
provide limited surge protection, if any at all.

Over-Water Performance.

Both the 5GHz and the 6GHz range of LigoWave
wireless products have been proven to provide a
high level of performance in over-water scenarios.
LigoWave’s iPoll and W-Jet proprietary protocols
reduce latency, stabilize jitter, and automatically
control transmission power, this way ensuring
optimum performance in various conditions,
including above-water links.

Case Studies of Over-WaterScenarios Using LigoWave:

304km RapidFire 5 Wireless Link Test in Italy

The longest unamplified Wi-Fi link was set up using LigoWave’s RapidFire 5GHz bridges. It extended a total of 304km, ~214km of which was over the Tyrrhenian Sea. The RapidFire-based link performance peaked at 100Mbps and 173,693PPS with zero packet loss. Tests were done by the CISAR Italian Center for Radio Activities together with Telcomms Srl, LigoWave’s partner in Italy.

3.1km LigoDLB 6ac Link in Russia

A 3.11km link was set up using the DLB 6ac wireless access point plus a 28dBi Cyberbajt DishEter external dish antennas. About 1 kilometer extended over water. The water did not interfere with the link’s performance and stability, even with a lower transmit power. It reached 460Mbps with approx. 90,000 packets per second.

Reliable Performance.

The 802.11ac-based hardware ensures high-packet throughput with up to 256-QAM. Performance is boosted with the iPoll and W-Jet proprietary protocols, which optimize client device activity and prioritize missioncritical data—info and processes that drive fish farm operations. This improves data transfer efficiency and effectively saves processing power, allowing for a higher CPE count—upwards of 70 client devices per base station spread across numerous fish farming sites.

Security.

On top of credential-based logins and AES-128 data encryption, LigoWave provides management frame protection. It defends the network against rogue packets that could disrupt the farm’s network, this way stopping farming operations and surveillance streams. Also, data is transferred using iPoll (DLB series) and W-Jet (PTP/PTMP series) protocols, meaning that the proprietary signaling mechanisms add an extra layer of security against unauthorized access.

Simplified Deployment.

• Since cost is a significant factor in wireless networking, LigoWave offers a set of tools and features to minimize time and money spent on network setup and maintenance:
• Setup Wizard, which guides users through initial LigoPTP device configuration.
• LigoWave OS, a built-in intuitive GUI that allows users to directly set up and manage individual devices.
• Infinity Controller, wireless cloud-based network management for manual and automated setup, control, maintenance, and monitoring of wireless LigoWave networks.
• Simple Mode, a GUI mode that shows all of the essential device settings in one window.
• Built-In Tools—Spectrum Analyzer, Site Survey, Link Test, Antenna Alignment, and Ping&Trace—included in LigoWave outdoor devices and accessed through their GUI.
• Innovative Mounts that provide alignment flexibility and require minimal effort with installing the devices on poles or walls.
