Virtual Fencing Specifications

This specification is for a wireless network system to support virtual fencing trials in specific areas in Arizona, USA. The wireless network shall support the Vence Cattle Rider collar and Vence Herd Manager web application. The wireless network is envisioned to be comprised of several remote base stations supporting appropriate wireless technologies to enable communications with the Vence Cattle Rider collar and backhaul communications to cloudbased web services.

Network Topology and Coverage The wireless network provider shall supply predicted coverage maps to groundlevel end-points for each specified service each. The wireless network shall be implemented with “private network” infrastructure. Shared network services are not suitable for these efforts.

Network Infrastructure Mechanical and Physical

Network infrastructure equipment (e.g., base stations) shall be entirely standalone in nature requiring no physical connection to power or wired backhaul connectivity. Typically, this will be implemented via solar power/battery system and cellular wireless backhaul. Network infrastructure equipment shall be capable of operating with a minimum of 5 days of reduced sunlight. Network infrastructure shall have minimal impact and land disturbance at installation sights. Network infrastructure shall be installed with a surface mount approach utilizing earth anchors to affix to location. Network infrastructure shall be designed and installed to be tolerant to adverse weather conditions including winds of up to 100 MPH. Network infrastructure shall provide for protection against use of perches for raptors. Network infrastructure shall support minimum on-site user support. Site visits shall be less than once per year.

Network Infrastructure Wireless Parameters The network infrastructure shall utilize industry standard LoRaWAN protocol operating in 900 MHz ISM band. Network infrastructure shall support integration with LoRaWAN network servers utilizing ChipStack Network Server Stack. Network infrastructure shall support 16 channels selectable of full 64 available channels. Network infrastructure shall support transmit power control. Network infrastructure shall support configuration of channel set and transmit power within capabilities of LoRaWAN Regional Parameter V1.0.2 or 3. Network infrastructure shall support back haul connectivity to AWS servers via fixed IP addresses. Network infrastructure shall support Semtech packet forwarding mode. Network infrastructure shall be full certified to operate with US regulatory domains including FCC.

Network Infrastructure Access and Security Network back haul connectivity shall support firewall capabilities to specifics ports and IP addresses. Network back haul shall support HTTPS protocol with third party supplied SSL certificates. Network infrastructure back haul modem and LoRa Gateway shall be accessible via SSH with configurable username and password protection.

Network Infrastructure Monitoring Network infrastructure shall support remote monitoring of power subsystem and backhaul health. Network infrastructure shall support status messaging via SNMP of at least the following parameters: gateway health, gateway location, and TX power. Network infrastructure shall support monitoring of power subsystem via Modbus over IP protocol.

Network Tower Delivery and Setup A total of nine towers are needed. The company that gets the award will be required to come to the Nogales Ranger Station and construct 2 of the nine towers so that district personnel can use them as an example to construct the other 7 towers. All tools required for the construction of the 2 towers will be provided by the company. The government will not supply tools. All towers will be delivered to the Nogales Ranger Station 303 Old Tucson Rd, Nogales Az 85621.

Quality Assurance of Tower Construction Personnel must be certified to install all components and equipment.

Storage and Handling Towers, accessories, and other manufactured items delivered to the project shall be handled, transported and constructed to prevent damage of the towers. Materials stored at the project site shall be protected from weather.
