ETSI is about to publish V2X networking standards
ETSI aims to publish during May 2011 the networking-layer protocol standards for vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communications, along with their test specifications. In particular this includes the following protocols:
- GeoNetworking protocol layer: this is the basic V2X networking protocol operating over the link layer technologies (e.g. 802.11p)
- ‘IPv6 over GeoNetworking’ adaptation layer: this adaptation layer enables the use of IPv6 mobility protocols over the GeoNetworking layer
- Basic Transport Protocol (BTP): a light-weight, UDP-like transport layer serving applications over the GeoNetworking protocol
BroadBit’s experts are delighted that this maturity milestone is approaching, so that V2X technologies and VANET systems will have a solid and settled networking standard on which the future V2X product development will be based.
EGNOS Express Lanes idea wins second place in the Taiwan region of 2010 ESNC competition
‘EGNOS Express Lanes’ is an intuitive idea exploiting the use of high-accuracy satellite positioning for building an equivalent but more cost-efficient implementation of the ‘HOT lanes’ which are quickly gaining popularity in North America. This idea has been worked out by Andras Kovacs and submitted under the Taiwan region for the 2010 ESNC competition of innovative satellite navigation/positioning related ideas. Mr Kovacs is very pleased that the evaluating experts have recognized the potential traffic congestion management implications of this idea by awarding the second regional prize in this idea competition.
Utilisation of existing co-axial cabling for in-house IP-TV data delivery
One important issue that comes up with IP-TV installations is the arrangement of in-house data link from the internet router to the set-top-box(es). Traditional approaches involve the use of wifi-routers or powerline communications (PLC) adapters.
Many IP-TV operators start up their service by offering both of above options. In BroadBit’s experience, which relates to Central Europe, very few people choose wifi-routers because of their price and most customers find even PLC adapters too costly. Unless PLC adapter pricing is bundled into a service package offering, the majority of customers unhappily end up with having plain Ethernet cables running through their house.
However in many homes there is existing co-axial cabling in the walls, that may be utilized with a suitable adapter. BroadBit has developed such Ethernet-over-Coax (EoC) adapters for IP-TV data delivery. This innovative solution is fully passive – no power supply is needed for the adapters – and much more cost efficient than any other alternative. Its initial deployment has been very popular with IP-TV customers.

BroadBit joins ETSI
BroadBit is pleased to announce its joining of the European Telecommunications Standardization Institute (ETSI). Taking part in ETSI’s standardization work is one way through which BroadBit’s expertise in designing and testing vehicular communications networks supports its industrial partners. BroadBit will primarily contribute to the work of ETSI’s Intelligent Transportation Systems (ITS) committee.
