Description

Wireless communication device providing three-way multi-call service and navigation device providing three-way multi-call service and system and method for providing interpretation service using the same {Wireless Communication Apparatus Providing Conference Call Service and Navigation Apparatus Providing Conference Call Service and System and Method For Providing Interpretaion Service Using It}

The present invention relates to a wireless communication device for providing a three-way multi-call service, a navigation device for providing a three-way multi-call service, and a system and method for providing an interpretation service using the same.

Specifically, a wireless communication device and a three-way multi-call service providing a three-way multi-call service by providing a first wireless communication unit for long range wireless communication, a second wireless communication unit for short range wireless communication, a multi-call module, a mixing and a transmission unit. It relates to a GPS-based navigation device for providing, and also to a system and method for providing interpretation service using the navigation device and smart card.

Wireless communication is a communication system using a space as a transmission medium and transmitting information signals to electromagnetic waves at a transmitting side and radiating them into a space, and receiving a electromagnetic wave transmitted through the space to detect an original signal. Here, in terms of the transmission distance, it will be divided into long range wireless communication and short range wireless communication.

Long-range wireless communication methods include CDMA, W-CDMA, WIBRO, HSDPA, and the like.

CDMA is a digital mobile communication method using spread-band technology developed by Qualcomm of the United States, also referred to as code division multiple access and code division multiple access. CDMA digitizes data and then spreads it over the entire available bandwidth.

WIBRO (WiBro) is a wireless portable Internet technology that enables high-speed Internet while moving. Techniques applied to WiBro include OFDM, OFDMA, and the like.

High speed downlink packet access (HSDPA) is a 3.5th generation mobile communication method that can transmit and receive data at a much higher speed than W-CDMA or CDMA. This technology allows communication to be five times faster than W-CDMA.

Meanwhile, short-range wireless communication methods include Bluetooth, Zigbee, Home RF, WLAN, UWB (Ultra Wide Band), and the like.

Bluetooth is a short-range, one-to-many, wireless method for voice and data transmission. Unlicensed 2.4GHz ISM (Indestrial Scientific Medical) frequency band is used and the transmission speed is 1Mbps, and various terminals can be connected within 10m. The biggest feature of Bluetooth is that it can communicate with other information communication devices in a bag or pocket.

Zigbee refers to one of the IEEE 802.15.4 standards supporting near field communication. It is a technology for near field communication and ubiquitous computing within 10-20m in wireless networking field such as home and office. In other words, ZigBee is a concept of a mobile phone or a wireless LAN, and a feature different from the existing technology is that it communicates a small amount of information instead of minimizing power consumption.

HormRF also uses unlicensed 2.4GHz ISM frequency band, transmission speed is 0.8 ~ 1.6Mbps, service radius is 50m and modulated demodulation FHSS. It has N: N connection type and features 6 PC-based voice channels.

Wireless LAN is a flexible data communication system that replaces or expands existing wired LAN and provides the ability to send and receive data without using a wired network using radio frequency (RF) technology. The unlicensed 2.4GHz ISM frequency band is used and the transmission speed is 5.5 to 11Mbps. The service radius is about 50m, using 1: N connection structure and CSM / CA protocol, and has excellent features for data transmission.

Next, navigation is a system that expresses on a map using various data received through a GPS (Global Positioning System) satellite and indicates a desired position. Car navigation is a system that displays voice currents and destinations on a digital road map by using various radio waves received from GPS satellites and sensors mounted on the vehicle. . The navigation using GPS satellites provides accurate location, altitude, and time information continuously for 24 hours, and can be used in any weather conditions, which is very reliable. After all, navigation is a system that can find the desired location and information by using triangulation method from the data received from three satellites (GPS satellite) floating on the earth.

The most essential part of the principle of navigation begins with an understanding of GPS. Your car is moving through GPS to pinpoint your current location and distance to your destination. Unlike many devices that use GPS receivers (such as unattended camera search and traffic location indications), navigation uses GPS receivers to locate locations on a map. Car navigation using GPS is sometimes difficult to receive satellite signals in deep mountains, tunnels, underground roads, etc., and the vehicle's sensor is used to correct the vehicle's position.
