While various radio-based access networks are available for mobile users, the most commonly available network that offers performance sufficient for video applications is the third generation (3G) mobile phone. Download data rates are expected to improve when high-speed downlink packet access (HSDPA) becomes widely available. The network of choice may shift to WiMAX networks as soon as they become more available but when this will happen remains unclear. For low speed users, Wi-Fi hotspots are available as these offer the highest download data rates and the adoption of WMM allows QoS levels to be defined.
