3. KBC Networks fibre optic wireless network digital video broadcast www.kbcnetworks.com Wireless – What is MIMO Technology? What is MIMO technology? -Multiple In Multiple Out -IEEE802.11n -Use of multiple antennas at transmitter and receiver  KBC utilises 2x2 MIMO (2Tx, 2Rx) -Increased throughput  Max theoretical throughput 300Mbps -Increased range -No more bandwidth required

4. KBC Networks fibre optic wireless network digital video broadcast www.kbcnetworks.com Wireless - Dynamic Frequency Selection What is Dynamic Frequency Selection (DFS)? -IEEE802.11h -Prevents interference with military and civilian radars -Requirement of ETSI How does it do this? AP monitors spectrum AP selects unused frequency AP monitors environment for radar presence If radar detected cease transmitting Dynamically recommence on another channel
