WiMax Network on Trains and Public Transit System
JetPoE Switch Enables Seamless Broadband Connectivity
When you get onboard a modern train today with
sleek carriage construction and high tech solar
glass, little do you realize that it’s a “Cage” that you
have entered. Well to be more precise a Faraday
Cage, this in essence blocks the majority of Wireless
signals coming in or out of the carriage, so in
today’s age of high speed broadband internet you’ve
also walked into a bit of a desert, until now. Korenix
UK has been awarded a contract for the supply
of Korenix PoE 4706 Ethernet switches to Nomad
Digital Rail (NDR), a UK-based provider of specialist
mobile networks, for use on the UK West coast
Mainline passenger trains.
JetNet 4706, an improved and strengthen manageable industrial PoE switch, is the successor of Best Choice of Computex Taipei 2007 Award winner, the JetNet 3705/3705f. JetNet 4706 is designed for industrial PoE applications such as IP surveillance or wireless access points, where power source is not conveniently located. It supports intelligent PoE control and schedule management; each of the four PoE ports can be configured in a weekly schedule by hourly basis and PoE on/off can be remote controlled via SNMP and Web. JetNet 4706 is compliant to both IEEE 802.3af PoE as well as the pioneer standard of IEEE802.3at PoE Plus design (enhancement of 802.3af) for boosting PoE delivery up to 30W in each of the four PoE ports. JetNet 4706 can auto-detect 24V & 48V power input and deliver 24V & 48V PoE output allows more applications where 48VDC is not an option.
The two uplink ports of JetNet 4706 series can be configured as Rapid Super Ring ports recovering network failure in less than 5ms, or RSTP ports integrating with other standard switches. Full network management features such as SNMP v3, QoS, IGMP v3, LACP port trunk are all supported. If the powered device fails to respond after a pre-configured time interval, JetNet 4706 will reboot the powered device and continue to monitor the powered device in every pre-configured time interval. Also, unmanageable powered devices can be managed through JetNet 4706 software. The award-winning IP-31 rigid aluminum flat casing and wide operation temperature range ensure a reliable operation in places such mass transit vehicles or outdoor usage.
