Utilisation of existing co-axial cabling for in-house IP-TV data delivery

without comments

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

without comments

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.

GeoNet successfully concluded by Final Workshop

without comments

GeoNet concluded its activity with its Final Workshop that took place 29 January 2010 in INRIA’s premises in Paris, France. IPv6 GeoNetworking was presented together with its link with the related ITS development in CAR 2 CAR Communication Consortium, CVIS implementation and ETSI TC ITS standardization.

Moreover the functionalities of IPv6 GeoNetworking was shown in a real system including 3 cars, 2 road-side units and a control center. A (very simple) enhanced driver awareness application was demonstrated and numerous attendees could enjoy a ride to see the achievement.

The FP7-funded European project GeoNet designed, implemented, tested and pushed for standardization an IPv6 GeoNetworking architecture related to many other major initiatives like CAR 2 CAR Communication Consortium and CVIS.

Space propulsion publication

BroadBit-Space_PropulsionPre-print of an article submitted to the Astrophysics and Space Sciences Transactions journal:

We describe a solution for generating spacecraft on-board electricity in the megawatt power range. The introduced thermo-photovoltaic electricity generation works without magnets or external cooling; it combines operational simplicity with a good power per mass ratio.

Once in orbit, the system shall be capable of powering numerous missions within the inner solar system or a single long range mission.

Space exploration today is limited by the length of time and amount of fuel required for reaching desired destinations. An ideal propulsion design simultaneously features high Isp, high thrust power, and limited engine weight. Recent advances in nano-scale fabrication open up new possibilities for thermo-photovoltaic electricity generator design, and allow a the use of high-trust electric propulsion technologies. High-powered on-board electricity generation is key to reducing travel times to nearby planets and to the the expansion of space exploration horizons. The following sections describe each component of the proposed on-board electricity generator. …
