KBC Networks www.kbcnetworks.com network wireless fiber digital video broadcast Wireless – The Important Questions Is there line of sight? Can we get a Google Earth map of the site? Can we get a system drawing? What are the distances between nodes? Is there any other known interference? Are the cameras analogue or IP? Does the product need to be homogenised in the local territory?

KBC Networks www.kbcnetworks.com network wireless fiber digital video broadcast What is the Fresnel Zone? Range DistanceRequired Fresnel Zone Diameter (5GHz) 300m / 1000 feet4m / 14 feet 760m / 2500 feet6m / 20 feet 1.6km / 1 mile9m / 30 feet 6.4km / 4 miles18m / 60 feet 16km / 10 miles30m / 100 feet Fresnel Zone Diameter *All measurements approximate

KBC Networks www.kbcnetworks.com network wireless fiber digital video broadcast What is interference? NOT trees, buildings, weather, power lines or mobile phones IS Cordless phones, wireless LANs, amateur radio, radar, Bluetooth Interference is in-band noise Things to find out: Has there been a site survey? Is anyone using the frequency you are trying to use? Are the frequencies on site managed? What are the symptoms? Lower data rate Lower distance capability Dropped packets Lines/rolling pictures (analogue systems) What is Interference?

KBC Networks www.kbcnetworks.com network wireless fiber digital video broadcast Multiple In Multiple Out IEEE802.11n Use of multiple antennas at transmitter and receiver Increased throughput Increased range No more bandwidth required What is MIMO Technology?
15
KBC Networks www.kbcnetworks.com network wireless fiber digital video broadcast Prevents interference with military and civilian radars Requirement of ETSI What is Dynamic Frequency Selection? AP monitors spectrum AP selects unused frequency AP monitors environment for radar presence If radar detected cease transmitting Dynamically recommence on another channel
