The Cisco FM4500 Mobi is a is a high-performance mobility-communications radio transceiver, designed to deliver fast, stable connectivity from any slow- or fast-moving vehicle to a wayside network, particularly within mission-critical market sectors and in extreme environments.
The FM4500 Mobi has received numerous railway and transport certifications, making it a popular choice for deployment on many transportation systems in the USA and worldwide, as well as in ports, intermodal yards and mining environments. Its low-latency, high-bandwidth characteristics make it the class leader in a diverse portfolio of applications, including but not limited to computer-based train control (CBTC), real-time situation monitoring, and on-board client services for rail (such as Wi-Fi and VoIP).
The FM4500 Mobi is equipped with M12 connectors, making it the ideal choice for onboard communications in very high-vibration environments (such as mine trucks, terminal yard cranes and tractors).
Wi-Fi on board
Your passengers expect wireless high-speed connectivity everywhere, and FLUIDITY delivers it. With our trackside technology, we are able to deliver connectivity up to 500 Mbps to fast-moving vehicles and trains.
Works with FLUIDITY, our unique mobility solution
The FM4500 Mobi supports FLUIDITY, the ultimate broadband connectivity solution both for high-speed vehicles and very high-bandwidth situations.
Up to 500 Mbps of usable throughput is now a reality, no matter what the situation: Environments of extreme temperature and humidity, punishing vibration levels, safety-critical working conditions, demanding contractual requirements, and vehicles traveling at up to 225 mph/360 Km/h are all part of what the FM4500 Mobi was designed to handle.
FLUIDITY's seamless 'Make-before-break' approach ensures zero-millisecond handoff times, persistent network sessions, and can accommodate any type of data traffic.
Reduce the cost of network ownership by selecting the amount of throughput you need
Limit the cost of network ownership with FluidThrottle by selecting only the amount of throughput required. More throughput can be easily achieved by upgrading the system with software plug-ins when traffic requirements increase. FluidThrottle makes Cisco FM cost-effective and future-ready.
Prodigy 2.0 for reliable mission-critical applications
Our Multiprotocol Label Switching (MPLS)-based transmission protocol is built to overcome the limits of standard wireless protocols and to deliver an infrastructure with a higher level of reliability.
At the base of our innovative transmission protocol is a traffic optimization algorithm that allows every Cisco FM radio to assign a specific level of priority and reliability to every packet transmitted. The result is a better, more reliable, multiservice wireless infrastructure.
Web interface configures, monitors, and troubleshoots the wireless network
The Cisco FM4500 Mobi includes the FMQuadro web interface, which allows you to configure, monitor, and troubleshoot the wireless network in real time, without any additional software. To simplify the configuration of the wireless network, the radio has a built-in spectrum analyzer and a real-time bandwidth monitoring tool.
