A list of articles and news links related to vehicular networking around the world. (Part of our list of Intelligent Transportation & Sentient Vehicles: Related Links.)

  •  Quinetiq Wins LastMile Contract QinetiQ has secured a £6.2 million contract from LastMile Communications Limited to develop a wireless transceiver system that will enable the high-speed delivery of local information through a network of wireless nodes placed in existing roadside furniture
  •  Sony patents high power LED IVC The system will rely on high-power LEDs built into car headlights. These can produce an apparently continuous beam that is in fact flashing very rapidly to communicate encoded messages.
  •  EU Project to Develop IVC device CVIS (Co-operative Vehicle-Infrastructure Systems) is new four-year technology research project, covering the design, development and testing of technologies to allow cars to communicate with each other and with the nearby roadside infrastructure over a wireless network.
  •  Broadband via Satellite for Trains Current WiMAX deployment said to be unreliable, possibility for using LEO satellites instead (approved by OFCOM, available in perhaps a year).
  •  Find a Parking Space Using Your Phone A service starting in Paris next month is designed to make life somewhat easier for harried drivers by allowing them to find out, in real time, whether there are parking spaces available nearby by using their cellphones or GPS navigation devices.
  •  OnStar in Every Vehicle Hughes will launch two new high-powered geostationary satellites that'll be able to deliver targeted content to millions of vehicles nationwide, while a dense array of ground-based towers operating in the same frequency range fill in the gaps in coverage and (more important) receive data coming back from the cars, doing an end-run around the cellular network.
  •  Realistic Vehicular Movement Traces for IVC Simulations For the evaluation of inter-vehicle routing schemes, we use a 24 hour detailed car traffic trace file generated by MMTS. The file contains detailed simulation of the area in the canton of Zurich, this region includes the part where the main country highways connect to the city of Zurich, the largest city in Switzerland. Around 260'000 vehicles are involved in the simulation with more than 25'000'000 recorded vehicles direction/speed changes in an area of around 250 km x 260 km.
  •  Hacking RDS-TMC Traffic updates over radio include no authentication mechanisms, so incorrect updates can be sent to cars' navigation systems.
  •  Uses of Municipal WiFi Mostly governmental rather than the public at large. Actual large-scale metropolitan deployment in Corpus Christi.
  •  WiFi Deployment in Palo Alto Plans for a WiFi network that will cover every city in San Mateo and Santa Clara counties, an area of 1,500 square miles.
  •  The DSRC FAQ DSRC is a short to medium range communications service that supports both Public Safety and Private operations in roadside to vehicle and vehicle to vehicle communication environments. DSRC is meant to be a complement to cellular communications by providing very high data transfer rates in circumstances where minimizing latency in the communication link and isolating relatively small communication zones are important.
  •  Article explaining 802.11a Fundamentally, the protocol remains IEEE 802.11a. It just does so at a half-clock rate while operating in the DSRC spectrum. To accommodate the needs of the vehicular environment, it also has undergone slight modifications to parameters like RSSI sensitivity and adjacent-channel rejection.
