Synopsis of B-CDMA Wireless Conference systems
DLP SYSTEM Wireless Conference System avoids other wireless frequencies incoming from the neighbor and automatically
selects and uses another 16 frequencies available, which prevents wires from being crossed and interfered. And this system has
a structure which replaces frequencies which errors occur a lot with new frequencies real time and controls to prevent interference
between frequencies from occurring by monitoring the quality of frequencies even during frequency use.

Binary-CDMA Wireless Conference System
Functions
. The system for chairman’s use a mutes or resets every microphone.
. Owing to speaker built-in feature, it is use without a sound device and can be used by connecting to
the outside sound system.
. It is used free without feeling a limit in space due to no wires.
. As main control does need outside power, the whole system can be used outdoors.
. A control unit controls monitor volume in wireless and provides audio output.
. Uses 10 hours with one-time charge by large-volume chargeable Li-polimer battery.
. Chairman types have a mute function which blocks voices, reset function and an automatic-ascending
function which automatically turns off the previous speaker’s voice at a time when another speaker
enters the conference.
. Automatic tracing camera control function to be added in the future.
. Manage the Vote function included vote function by LCD display

ㆍ Infrared rays : Communication distance is significantly short, and it can be blocked
when it has interference, and collision.
ㆍ RF : Communication distance is short, and it is impossible to move other places.
ㆍ B-CDMA : Communication distance is very long, and it is possible to move other places
completely.
