Wireless backhaul radios provide the high-speed communications links that connect remote network locations to a central network without requiring fiber or copper infrastructure between sites. These point-to-point (PtP) and point-to-multipoint (PtMP) radios are commonly deployed on towers, rooftops, utility poles, water tanks, and other elevated structures to transport Ethernet traffic for surveillance systems, Wi-Fi access points, public safety communications, utility networks, and enterprise connectivity.

Because these radios are frequently installed in locations where commercial AC power is unavailable or costly to install, Power over Ethernet (PoE) has become the preferred method for delivering both electrical power and Ethernet data over a single Category cable. PoE simplifies installation, reduces infrastructure costs, and eliminates the need for separate electrical wiring.

Modern wireless backhaul radios often require IEEE 802.3at (PoE+) or IEEE 802.3bt (4-Pair PoE) to provide sufficient power for high-performance radios capable of multi-gigabit throughput over long wireless distances. However, standard Ethernet is limited to 100 meters (328 feet), which can restrict equipment placement when radios must be mounted high on towers or located far from network equipment.

PoE Injectors solve the first challenge by adding standards-compliant PoE power onto an Ethernet cable from a non-PoE switch or router, allowing a single cable to carry both data and power to the radio.

When cable runs exceed the 100-meter Ethernet limit, PoE Extenders regenerate both the Ethernet signal and PoE power, allowing additional cable segments to be added while maintaining reliable network performance. Multiple extenders can be deployed in series, depending on the power requirements of the connected radio and the available PoE power budget, enabling installations well beyond the traditional Ethernet distance limitation.

Together, Omnitron PoE Injectors and PoE Extenders create a flexible and cost-effective infrastructure that enables network designers to place wireless backhaul radios in their optimal RF locations rather than where electrical power is available. This approach improves wireless coverage, increases deployment flexibility, reduces installation costs, and accelerates network expansion for service providers, municipalities, utilities, transportation agencies, and enterprise campus networks.

Overview

A regional wireless network provider was expanding its high-capacity wireless backhaul infrastructure to connect surveillance systems, municipal facilities, and remote communications sites. The deployment required powering high-performance wireless radios installed on towers, rooftops, utility poles, and other elevated structures where local AC power was unavailable or difficult to install.

The customer required a reliable solution capable of delivering both power and data over extended Ethernet distances while supporting the power requirements of modern wireless backhaul radios. Omnitron's Power over Ethernet (PoE) Injectors and PoE Extenders provided a simple, cost-effective solution that eliminated the need for local power while extending Ethernet connectivity to remote radio installations.

The Challenge

Deploying wireless backhaul radios in remote outdoor environments presented several networking and power delivery challenges:

• Many radio locations lacked nearby AC power, making electrical installation expensive and time-consuming.
• Standard Ethernet cabling is limited to 100 meters (328 feet), restricting radio placement.
• High-performance wireless backhaul radios often require higher PoE power levels than traditional IP devices.
• Outdoor equipment must operate reliably across wide temperature ranges and harsh environmental conditions.
• Network downtime directly impacts connected surveillance cameras, public safety systems, and wireless network availability.
• Customers required a simple deployment that minimized maintenance and truck rolls.

The Solution

The customer deployed Omnitron PoE Injectors at the network equipment location to provide IEEE-compliant PoE power and data onto Ethernet cabling leading to the wireless radio.

Where cable distances exceeded the standard Ethernet limitation, Omnitron PoE Extenders were installed between the injector and the wireless radio. The extenders regenerated both Ethernet data and PoE power, allowing the network to reach remote installations beyond the traditional 100-meter limitation.

The solution provided:

• High-power IEEE 802.3af/at/bt PoE support for wireless backhaul radios
• Extended Ethernet distances using one or multiple PoE extenders
• Simultaneous transmission of data and power over a single Ethernet cable
• Plug-and-play installation requiring minimal configuration
• Industrial-grade reliability for outdoor and remote deployments
• Reduced installation complexity by eliminating local AC power requirements

This architecture enabled reliable deployment of point-to-point and point-to-multipoint wireless backhaul radios serving remote network locations.

The Benefits

Omnitron PoE solutions were selected because they offered several advantages over conventional installation methods.

Reliable PoE Power Delivery

Omnitron injectors provide standards-based PoE capable of supporting today's high-performance wireless radios while maintaining reliable network operation.

Extended Reach

PoE Extenders overcome the traditional Ethernet distance limitation, allowing radios to be installed where they provide the best RF performance rather than where power is available.

Lower Installation Costs

By transmitting both power and data over a single cable, the solution eliminates the expense of installing AC electrical service at remote mounting locations.

Industrial Reliability

Omnitron products are engineered for continuous operation in demanding outdoor environments, making them well suited for wireless infrastructure applications.

Simple Deployment

The plug-and-play architecture reduces installation time and minimizes maintenance requirements throughout the network lifecycle.
