This goal is to realize a multi-mode terminal on vehicle that can download communication and application software by wireless and then can easily access new services without purchasing additional new equipment, even if services/communication system is modified or newly introduced.

1-Technology to develop multi-band antenna and RF circuit which can transmit/receive RF signals through various media with different frequencies.

2-Technology to adaptively modulate and demodulate signals for various kinds of media (DSRC, VICS, terrestrial digital broadcast and others) with software processing.

3-Technology to efficiently receive data under the mobile communications environment

[edit] Multi-band high-frequency radio technology

  • -Automobile mounted multi-band antennas using ceramics with advanced thermal properties and broadband antennas to provide a flexible correspondence to different forms of media.
  • -Multi-band RF circuits which will be adaptive to several frequency bands, channel bandwidths for various media.

[edit] Software defined radio technology

  • -Adaptable modems compatible with various forms of media using wireless downloading of software.
  • -Adaptive modem that changes the modulation scheme depending on the radio propagation condition, and linearization technology.
  • -Software demodulation technology for digital broadcasts to provide a common platform for all types of services.

[edit] Multi-mode signal processing technology

  • -This technology will enable stable mobile communication by selecting an appropriate media and controlling data transmission, in conformity with data on the field strength of the available communication media, and the attributes of the incoming content.
