OCPP - An EV Charging Protocol

Nowadays, the growing CO2 emissions are one of the main international issues. The world is becoming aware that the current climate issues start being critic and that something has to be done. In parallel, Earth starts running out of fossil fuels so alternative energies and alternative ways of producing energy have to be found. Driving electric vehicles would reduce the CO2 emissions and the use of fossil fuels.

Wireless Charging - The Future of Electric Vehicle

Wirelesses charging of electric vehicles continue to be one of the most researched areas of wireless power transfer.  By reducing the reliance on fossil fuels, electric vehicles provide a sustainable and environmentally safe means for fuelling our vehicles well into the future.
What is Wireless EV Charging?
The growing EV market stimulates the demand for more convenient and reliable means to recharge the battery. WPT (Wireless Power Transfer) technique requires no physical contact between vehicle and charging device, therefore overcomes the inconvenience and hazards caused by traditional conductive method.
The initial objective is replacing conductive charging method by the novel WPT technology, while maintaining a comparable power level and efficiency. The long-term goal is to dynamically power the moving vehicles on road. This will lead to a much reduced battery pack but extended driving range. Then, the main concerns of EV, namely the high battery price and the range anxiety, will be …

CHAdeMO – EV Super-Fast Charging

About CHAdeMo Protocols…..
CHAdeMO is a DC charging (6kW to 50kW with 150kW) standard for electric vehicles. It enables seamless communication between the car and the charger. It is developed by CHAdeMO Association, which is also tasked with certification, ensuring compatibility between the car and the charger.
First introduced in 2009 with the Japanese-market Mitsubishi i-Miev, the CHAdeMO standard is capable of recharging the battery packs of cars like the Nissan LEAF and Kia Soul EV from empty to 80 percent full in as little as 30 minutes.  Used on everything from electric motorcycles to full-size electric busses, CHAdeMO is also the world’s most commonly used DC quick charge standard, with what we’d estimate to be more than 100,000 CHAdeMO-equipped vehicles on the road.

It was defined by the CHAdeMO Association – Purpose/focus CHAdeMO Association aims to increase quick-charger installations worldwide and to standardize how to charge the vehicles. – http://chademo.com. CHAdeMO was fo…

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…

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 …

White-Fi Technology

Microsoft is looking at starting a pilot project of its ‘White-Fi’ technology that uses the unused spectrum in frequencies used for broadcasting of television signals, and is likely to offer solution to tackle the problem of last mile broadband connectivity in the country.
“In a country of massive change, digital divide can pose serious challenge. In all the initiatives by the government — Digital India, Swachh Bharat or Jan-Dhan Yojna — technology has a role to play, and we want to be part of it,” Microsoft India Chairman Bhaskar Pramanik said, adding that at present, the company was talking to all stakeholders, including the government, for its ‘White-Fi’ technology to provide last mile connectivity. What is White Fi/Space? White Space refers to the unused broadcasting frequencies in the wireless spectrum. Television networks leave gaps between channels for buffering purposes, and this space in the wireless spectrum is similar to what is used for 4G and so it can be used to deliver …

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…

Smart Cars for Today and Futures !!

Smart Cars for Today and Futures …
The Smart car was originally designed as an economic solution to fuel efficiency and pollution, while at the same time providing a practical resolution to parking problems everywhere. Depending on the model, the two-passenger compact car is approximately eight to nine feet long, five feet tall and five feet wide. Smart cars are designed to be able to park perpendicular in a parallel parking space, allowing room for two Smart cars in one normal sized spot or driveway. Gas mileage also depends on the style and engine horsepower of the car, but typically gets 46 miles per gallon with city driving and 69 miles per gallon with highway driving. The plastic bodies of the Smart car were also made to be recyclable. The first important thing to know is that self-driving cars are not street legal yet. While they can be driven on closed courses, these fully autonomous cars are not yet available to purchase. There is a difference between smart vehicles and autono…

HaLow - Future Of WiFi....

What is HaLow?

There's a new wireless networking protocol in town and it comes to bring connectivity to the Internet of Things. Wi-Fi HaLow (pronounced "HAY-low") is a marketing name used for products that utilize the IEEE802.11ahwireless technology, which offers longer range and lower power connectivity than traditional WiFi-certified products.

Wi-Fi HaLow is the latest specification from the Wi-Fi Alliance looking to expand the range of Wi-Fi's connectivity options. Wi-Fi HaLow will be able to easily work through walls and large barriers because of the propagation capabilities of low-frequency radio waves, as it will operate in the unlicensed wireless spectrum below 1GHz. HaLow’s range will be nearly double the range of today's Wi-Fi, with estimates extending as high as a whopping 3,280 feet.
HaLow is designed for the Internet of Things, designed to connect multiple devices wirelessly, over extended distances and using lower power.  802.11ah HaLow: for low dat…
