In an era where high speed networks are affordable and readily available, video streaming in high quality over IP has replaced the costly video broadcasting over analog or lease lines as a more flexible and cost-effective solution. Compare with regular data transmission, stricter requirements must be met for streaming broadcast-level video over an open Internet, where uneven deliveries, packet loss and buffering are unacceptable. For high quality video broadcast services such as video on demand (VOD) and over the top (OTT), user experience very much depends on continuous and seamless packet delivery over an open Internet.
Wireless Internet has moved from being a luxury to being an expected staple of life in hotels, conference venues, hospitals, university campuses and numerous places besides. With the proliferation of smart phones and tablet PCs the demand for wireless coverage in public spaces has increased dramatically.
