How Technology Can Be Short Range Communication

Decent Essays

ABSTRACT

Car to car communication is a leading technology that may hit the market in upcoming two –three years .The technology that warns for imminent collision will be in cars soon and it will help car to transit their position, speed, steering wheel position and other data with other cars within 100 meters. Many cars have tools that use radar or ultrasound to identify the hurdle but the range of sensor is limited to certain length and they can’t detect the obstacle. So this technology which use higher-level technology which can be helpful in many prospects. Technologies thatC2C Communication uses are Dedicated short range communication (DSRC), Wireless LAN, GPRS, CLOUD, Mesh Network, This technology is reviewed by MIT and General …show more content…

2.2 Wi-Fi network

Because one of the possible frequencies is 5.9GHz, which is used by WiFi, but it’s more accurate to say “Wi-Fi-like.” The range is up to 300 meters or 1000 feet or about 10 seconds at highway speeds (not 3 seconds as some reports say).

2.3 Mesh Network

Car-to-car communication would be a mesh network, which means every node (car, smart traffic signal, brakes etc.) can transmit, capture and retransmit signals. Approximately five to ten hops on the network would congregate traffic state a mile ahead. That would be sufficient time for even the most inattentive driver to take care off.

2.4 GPRS (General Packet Radio Service)

• A packet-switched technology that allows data communications.
• GPRS is a packet-based wireless communication service that provides data rates from 56 up to 114 kbps
• It supports a wide range of bandwidths.
2.5 CLOUD In car the sensor and actuator device requires to closely work with each other. Each car needs to cooperate with other car in car-to-car (c2c) in order to share and make use of external resources in an efficient way. To ease the interaction between drivers and another car driver and world, a vehicle cloud (Cloud) architecture with real time services is introduced. The implementation of cloud computing is economical.
