For many transit systems — from buses and light rail to paratransit and heavy rail — connectivity is taking center stage in those initiatives. Robust Wi-Fi has become a must-have for passengers who want to be productive during their commutes. Simultaneously, operators also want to tap that same connection for additional uses such as fare collection, security video, passenger counts, computer-aided dispatch/automated vehicle location, and vehicle diagnostics. Altogether, that requires increasing levels of network speed, reliability, scalability, and manageability. That’s where WAN bonding enters the picture.
With WAN bonding, we combine two or more separate WAN connections (ideally from a diverse set of carriers) into a single virtual/logical connection. This WAN bonding strategy provides a host of benefits:
WAN bonding involves three key functions:
WAN bonding requires the right equipment and software. First, you need an Internet device, such as Digi’s TX cellular routers, which are purpose-built for transportation use cases.
You will also need a way to integrate WAN Bonding technology. Digi has done this integration for you, with Digi WAN Bonding — a value-added service available as an add-on to your Digi Remote Manager® (Digi RM) premium subscription. Digi RM is a complete monitoring and management platform that enables network managers to fully monitor and orchestrate their distributed Digi devices.
Digi can also work with you to design your network topology and ensure WAN bonding can be effectively implemented. Whether you work with Digi Professional Services, or you use your own implementation team, the next step is to determine the number of WAN connections required, the location of the WAN bonding server, and the routing of traffic between the different connections. Next, configure and set up the WAN bonding software. This involves specifying different WAN connections, configuring routing and performance settings, and setting up failover protection.
WAN bonding enables transportation authorities to offer and use Internet speeds that greatly exceed any single connection for the myriad connected devices and data-intensive applications on today’s modern trains and buses.
Digi WAN Bonding provides resilient connectivity and maximum performance across multiple connections in an easy-to-implement solution. Developed by a Digi technology partner, Bondix Intelligence, the Digi WAN Bonding software ensures reliable voice, video, and data transmission connectivity for both mobile and stationary deployments. Digi WAN Bonding enables customers with Digi RM running DAL OS on their Digi devices to centrally set up, deploy and manage the bonding together of multiple WAN connections.
This WAN aggregation supports dramatically increased throughput speeds, WAN smoothing, packet redundancy and seamless failover for always-on Internet connectivity. The key features include:
With WAN bonding, your transit organization can combine multiple WAN connections into a single, virtual connection. Digi WAN Bonding harnesses these capabilities to improve network performance, reliability, and redundancy. With advances in technology and the increasing demand for reliable and secure network connections, the future of WAN bonding looks promising. Organizations that are looking to improve their network performance and reliability should consider implementing WAN bonding as part of their overall network strategy.
