Video Streaming over 802.11b with Human and Bluetooth Interference: Evaluating the Performance and Measurement of Video Streaming in the Test Environment Karma Kelzang Eudon

Technology is overtaking the world of communication and application like messaging, emailing, chatting and video streaming have become a part of our daily lives. Video streaming refers to real-time transmission of video which means the audio and video signals must be sent or received continuously. If this does not happen then it causes discomfort both in our eyes and our ears. These signal qualities are affected by signal fading and this fading could result due to interference or obstruction of these signals. This book explores the quality of video streaming in a test environment set up within the university campus using a laptop, Bluetooth device, a Wi-Fi finder and a spectrum analyzer. The measurements were taken in the presence of human traffic and other technology using the same unlicensed band at various locations in the test environment. It is definitely challenging to meet the requirements of video delivery as a result of co-channel interference and signal fading due to obstructions but can other technology using the same unlicensed band contribute to signal fading? Can human shadowing be one of the reasons affecting the video streaming quality?
