KBC Networks network wireless fiber digital video broadcast Welcome

KBC Networks network wireless fiber digital video broadcast Wireless

KBC Networks 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 network wireless fiber digital video broadcast What is Line of Sight? Not Line of Sight Fresnel Zone

KBC Networks 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 network wireless fiber digital video broadcast Google Earth Map

KBC Networks 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?
