The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Ultra-reliable wireless is essential for critical applications
Automation is growing across industries. Autonomous vehicles, robots, and teleremote applications are becoming more prevalent as industrial organizations digitize their operations. Reliable wireless technologies are not only an enabler but critical to the success of these deployments. Mobile assets cannot tolerate dropped connections or network latency; lost packets can jeopardize safety, create line stoppages, and compromise productivity, with severe operational and financial consequences.
Reliable wireless also brings greater flexibility to the environment, while also potentially reducing costs and installation times to connect fixed assets. Fiber isn’t available everywhere and can be prohibitively expensive to deploy and maintain. By using wireless technology:
● Factories can easily reconfigure product lines and adapt quickly to changing market demands.
● Ports, mines, and rail can extend their connectivity to wherever they need it to increase automation and provide critical services.
Cisco®’s Ultra-Reliable Wireless Backhaul (URWB) technology addresses these complex fixed and mobile use cases, delivering advantages across the network:
● Provides multigigabit high-throughput performance, connects moving assets, and links locations that need temporary connectivity.
● Delivers ultra-low latency, zero loss, and seamless handoffs.
● Extends 802.11 technology and uses unlicensed spectrum, reducing costs and complexity and making it easy to deploy pretty much anywhere.
● Since URWB is based on the 802.11 standard, IT and OT teams find it easy to understand and deploy.
URWB supports different architectures:
● Mobility: Connectivity between radios deployed on vehicles and fixed structures or just between vehicles is generally used to connect Automated Guided Vehicles (AGVs), autonomous mobile robots (AMRs), trains, and other moving assets.
● Fixed infrastructure: Connectivity between radios attached to fixed structures ‒ poles, towers, buildings, etc. ‒ is generally used to support wireless backhaul, physical surveillance, and more. The layout and data communication can be implemented through Point-To-Point (PTP), Point-To-Multipoint (PTMP), and mesh topologies.
Reliability is mandatory for industrial wireless automation. Applications such as AGVs and AMRs, cranes, and teleremote applications need real-time response. Any delay or loss in connectivity causes productivity to slow or stop, and safety can be jeopardized.
Reliability for wireless connectivity for critical moving assets is achieved by a solution that delivers:
● Low packet loss and error rate
● Low, predictable latency
● Seamless handoffs between access points
● RF spectrum interference mitigation in “noisy” and dynamic environments
URWB delivers reliable wireless as it fulfills these requirements. This is possible thanks to a specialized implementation of Multiprotocol Label Switching (MPLS)-over-wireless link protocol, created to overcome the limits of standard wireless protocols when transmitting any IP-compatible traffic with very low latency in a mobility context. A “make-before-break” procedure enables moving vehicles to reliably move the connection to the next access point along their path without any interruption in connectivity.
URWB networks can be designed for Layer 2 use cases (such as when connecting AGVs or AMRs in a factory floor) as well as Layer 3 use cases (such as for train-to-trackside communications in subways or railways), allowing the network to scale in size without compromising reliability and availability.
With Multipath Operations (MPO) technology, URWB can deliver uninterrupted connectivity to fast-moving devices by sending high-priority packets via redundant paths. It can duplicate protected traffic up to eight times and avoid common paths.
This functionality, combined with cutting edge hardware capability, can further reduce latency and improve reliability, addressing both interference and hardware failures.
Industries are embracing URWB to increase productivity and safety
Cisco URWB has been helping organizations from different industries to achieve their business goals with dependable wireless connectivity for their most critical applications.
Utilities and renewables
For ScottishPower Renewables, URWB provided critical long-range wireless connectivity for sea vessels during construction and the operational phases of offshore wind farms.
Ports and terminal operations
Several ports and terminal operators have successfully been using URWB to connect cranes, teleremote machinery, and autonomous or automated vehicles such as AGVs. A few examples include La Spezia Container Terminal, Malta Freeport Terminals Limited, and ThPA S.A. Port of Thessaloniki.
Manufacturing
URWB has been enabling manufacturers to connect not only their moving vehicles and mobile tooling, but also their product lines as wireless provides more flexibility and lower costs with no need for cabling. General Motors has been using URWB to capture data from vehicle sensors during performance testing in real time and adjusting the vehicle on the track, streamlining the process and saving time, thus accelerating time to market for commercially ready vehicles. Other manufacturers have successfully been using URWB to quickly deploy their growing numbers of AGVs. URWB provides the reliable, uninterrupted reliability that these applications need.
Rail
Because URWB delivers seamless handoffs even at high speeds, rail organizations have been using URWB to connect applications such as Communications-Based Train Control (CBTC), sensors, video data offload, onboard Wi-Fi, and real-time security video monitoring. And they are successfully maximizing passenger satisfaction, supporting safety and control applications, and maintaining situational awareness.
Mining
Mine automation boosts productivity, helps ensure consistent operations, and promotes worker safety. Mines have been using URWB to enable vehicle-to-ground communication for vehicle automation and real-time video monitoring with low latency and seamless handoff for even the most critical applications.
Smart cities, education, digital divide
Since URWB is cheaper and faster to deploy than fiber, it is an ideal technology to deliver consistent broadband connectivity in cities, schools, and universities. Canutillo Independent School District deployed the URWB technology to connect Wi-Fi hot spots in remote locations with poor internet coverage so thousands of students could learn from home during the COVID-19 pandemic. The City of Fort Worth used URWB to provide free Wi-Fi access for 40,000 residents in 10,000 lower-income households to help them access city services, telehealth, job market information, and educational opportunities.
Parks and entertainment
URWB has been used to successfully connect dark rides in entertainment parks. Rides need ultra-reliable wireless to provide safety and a good experience for passengers. Ride vehicles move, sometimes in high-speed, in closed areas with walls and obstacles. Any interruption in connectivity can jeopardize the guest’s experience, as sound and visual effects synchronization can be affected.
URWB was introduced in the market in 2012 by Fluidmesh Networks, which was acquired by Cisco in 2020. Since its inception, the technology has continued to evolve. Today, we have a totally refreshed new Cisco product line, all based on 802.11ax, with new innovations that further improve its reliability and security.
Our URWB hardware can also run Wi-Fi 6/6E access point mode. This dual-mode capability enables you to decide which technology to use depending on the project requirements. The operational mode can be swapped in the field to adapt the product to the specific use case, facilitating the transition between the two technologies, and optimizing the investment.
