Q-Free has been awarded three-year US$3.8 million contract for its OBU615 tags by Sociedad Concesionaria Autopista Central in Chile, starting in January 2015. The compact OBU615 is designed to blend unobtrusively into the interior of any vehicle. New low-power technology ensures the lowest possible current draw while 5.8 GHz CEN-compliant DSRC processing. New signal discrimination technology enables an extended lifetime and immunity to radio frequency (RF) interference from the many kinds of wi-fi-enable

Canadian company Sierra Wireless has deployed its InMotion Solutions oMG Mobile Gateway for Denver’s Regional Transportation District (RTD) to support mobile broadband access for automatic vehicle location (AVL) and smart card fare payments aboard more than 1,100 buses in its fixed route fleet. One of the top 20 public transit agencies in the US, the RTD provides services to residents across an eight county metro area, from the bus and light rail services to the free MallRide and specialty services.

Colin Sowman catches up with the latest moves in the 5.9GHz exclusivity debate. The Wi-Fi Innovation Act, recently introduced to both the US Senate and its House of Representatives, moves into a new phase in the debate over the exclusive right of the 5.9GHz band for Vehicle to Vehicle (V2V) communications. If the Act comes into law, it would require the Federal Communications Commission (FCC) to conduct tests across the whole 5GHz band to determine if the spectrum can be shared without interfering with curr

With the Sencity Road MIMO, Huber+Suhner is extending its portfolio of rooftop antennas for buses, commercial vehicles, trams and underground railways. The new Sensity Road MIMO is able to achieve a far higher data rate than a standard antenna, supporting applications with very high data rates, such as passenger information systems, passenger monitoring or internet on board. Depending on the version, this compact omni-directional antenna includes two broadband radiating elements for 2G/3G/4G mobile c

Caldecott Tunnel’s new Fourth Bore is utilising a bespoke high-capacity monitoring and communications network from Moxa. The Caldecott Tunnel connects Contra Costa and Alameda counties in Northern California and traditionally it has suffered severe congestion - especially during peak hours. Opened in 1937 as a twin-bore arrangement, by 1964 the increase in traffic volumes led to a third bore being added. Shortly after the third bore was opened a tidal flow was introduced with the centre bore alternating in

Sensys Networks has released new software features to shield customer’s wireless traffic detection systems from attach by vandals and notify them when attempts of unauthorised access are made. These enhancements are available now for existing installations and will be deployed wirelessly using the normal software update process. There is no cost for the software enhancements, nor is new hardware required. These enhancements are optional, and will be included in all new hardware and software produced by S

Econolite and Sensys Networks have entered into a collaborative sales, marketing and technical initiative that will see Econolite will offer the Sensys Networks VDS240 series of wireless flush-mount vehicle detection sensor products in select regional markets. While Econolite has a proven track record of more than 20 years of providing above-ground detection that has helped power some of the world’s most successful intelligent transportation systems (ITS), there are many applications that require an in-g

According to a new research report from analyst firm Berg Insight, the global cellular machine to machine (M2M) market has entered a period of transition from 2G to 3G/4G technologies. The share of cellular M2M devices connected to HSPA/LTE networks is projected to more than double from less than 20 percent at the end of 2014 to more than 50 per cent by 2018. When it comes to device shipments, 3G/4G is expected to overtake 2G already in 2017. HSPA will be the largest technology in an intermittent period unt

With permission from a local road agency, researchers in from the University of Michigan hacked into nearly 100 wirelessly networked traffic lights, highlighting security issues that they say are likely to pervade networked traffic infrastructure around the country. More than 40 states currently use such systems to keep traffic flowing as efficiently as possible, helping to reduce emissions and delays. The team, led by University of Michigan computer scientist J. Alex Halderman, found three major weaknes

According to a new research report from the analyst firm Berg Insight, the number of global mobile network connections used for wireless machine-to-machine (M2M) communication will increase by 21 per cent in 2014 to reach 213.9 million at the year-end. East Asia, Western Europe and North America are the main regional markets, accounting for around 75 per cent of the installed base. In the next five years, the global number of wireless M2M connections is forecasted to grow at a compound annual growth rate
