Each meeting room of EErDuoSi City Government covers more than 150 m2. For this conference equipment upgrade, they adopt Relacart WDC-900 2.4G Digital & Wireless Conferencing Discussion System, operating in 2.4GHz (license free) band and Zigbee wireless communication protocol. ZigBee communication protocol provides three level security modes, avoiding illegal access to data. And it adopts advanced encryption standard (AES128) symmetric cipher, which is efficient forencryption during data transmission, ensures the safety of the meeting. 2.4GHz wireless transmission technology, which transmission speed and quality is more excellent than the traditional one. In physical definition, 2.4GHz transmission mode of total data rate is 2Mbit/s, while the CD level timbre is only 1.4M bit/s, so the high-fidelity circuit design ensures that the sound quality is more clear, and the 2.4G achieves the lossless transmission. Digital signal process is excellent immunity to the RF interference from PC, mobile phone and bluetooth and other devices. Bright LCD display, friendly operation interface, easy to operate, Chinese and English menu for option, the function is more complete. There are 3 conference operation modes for option: Auto, Request and FIFO. For the project is the government upgrade, Party A does not want too much change, which will influence the beauty of the building.
