An Electric Vehicle - Future Drive

What is an Electric Vehicle?
An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration.
How does An Electric Vehicle works? The electric vehicle power source is the battery which acts as a "gas tank" and supplies the electric motor with the energy necessary to move the vehicle.  This gives the car acceleration.  When the vehicle is idle there is no electrical current being processed, so energy is not being used up. The controller acts as a regulator, and controls the amount of power received from the batteries so the motor does not burn out. This battery powers all of the electronic devices in the car, just like the battery in a gas-powered car. Everything else in the electric car is basically the same as its gas-powered equivalent: transmission, brakes, air conditioning, an…

DSRC - Technology for Safer Driving !

What is DSRC?
DSRC (Dedicated Short Range Communications) is a two-way short- to- medium-range wireless communications capability that permits very high data transmission critical in communications-based active safety applications. In Report and Order FCC-03-324, the Federal Communications Commission (FCC) allocated 75 MHz of spectrum in the 5.9 GHz band for use by Intelligent Transportations Systems (ITS) vehicle safety and mobility applications.
Range – Up to 1000 m Data Rate – 6 to 27 Mbps Channels – 7 Licensed Channels 802.11p – aka Wireless Access for the Vehicular Environment (WAVE)
The U.S. DOT’s commitment to DSRC for active safety communications contributes to safer driving. Vehicle safety applications that use vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications need secure, wireless interface dependability in extreme weather conditions, and short time delays; all of which are facilitated by DSRC. Who Can Use DSRC Manufacturer Technologies? DSRC manufacturer t…

ITS - Intelligent Transport Systems

Intelligent Transport Systems
Intelligent Transport Systems (ITS) describe technology applied to transport and infrastructure to transfer information between systems for improved safety, productivity and environmental performance. This includes stand-alone applications such as traffic management systems, information and warning systems installed in individual vehicles, as well as cooperative ITS (C-ITS) applications involving vehicle to infrastructure and vehicle-to-vehicle communications.
Intelligent transport systems apply information, data processing, communication, and sensor technologies to vehicles (including cars, trucks, trains, aircraft and ships), transport infrastructure and transport users to increase the effectiveness, environmental performance, safety, resilience and efficiency of the transport system. Traffic Management, and Traffic Transactions enable efficient real-time management, and smart fees and payments for multi modal transport.
The following important technology …

Wireless Intrusion Prevention System (WIPS)

What is WIPS? - Awireless intrusion prevention system (WIPS)operates at the Layer 2 (data link layer) level of the Open Systems Interconnection model. A WIPS compares the MAC addresses of all wireless access points on a network against the known signatures of pre-authorized, known wireless access points and alerts an administrator when a discrepancy is found. To circumvent MAC address spoofing, some higher-end WIPS are able to analyze the unique radio frequency signatures that wireless devices generate and block unknown radio fingerprints. The primary purpose of a WIPS is to prevent unauthorized network access to local area networks and other information assets by wireless devices. These systems are typically implemented as an overlay to an existing Wireless LAN infrastructure, although they may be deployed standalone to enforce no-wireless policies within an organization. Some advanced wireless infrastructure has integrated WIPS capabilities.
Large organizations with many employees are…
