However, the offered services stay mostly similar. Phase 3 - High quality wireless multimedia services. All relevant multimedia services could be provided in a wireless manner. Phase 3 is a major step towards full multimedia capabilities in a wireless environment. Same multimedia services could be available as in wired environment. This phase sets the most stringent requirements to the underlying network. This phase, as well as phase 2, are strongly dependent of the overall multimedia development in the near future.
Percentage of failed Connection Establishments Figure 5 Percentage of failed connection establishments over the whole test period Independently of the nature of the failure, the test-users became easily frustrated when their attempt had failed several times. Once a connection was found, it proved relatively stable. Anyhow, sudden disconnection has always a severe effect on a test-use! Those who experienced a lot of network problems in the first days of the test soon lost interest. The time factor is probably also important.
Those who experienced a lot of network problems in the first days of the test soon lost interest. The time factor is probably also important. Re-establishing a connection must be easy and swift in future applications. Transmission speed is important. It is difficult to even imagine under what circumstances low data rates would be acceptable to a professional user without additional service support from the underlying network. The information value must then be of extreme height. The network is a commodity and of as much interest to users as petrol chemistry is to drivers.
