The user's selection of services used to be based on the data-rate, mobility and coverage. But these kind of preferences are the choices of each individual preference. All user, of course, want the higher data-rate, more powerful mobility and wider coverage. But there are the trade-off in Wireless Service. It is difficule for the mobility and data-rate to coexist at once. Because of this "trade-off" in wireless service, there are product differentiation.
The Ficure of Wibro and W-CDMA shows the product differentiation; Wibro is following up the data-rate service position, W-CDMA is the mobility service position. For each service position wants the fitting CAPEX planning for their customers and customers could select their preferences between Wibro & W-CDMA.
So the mobility 60km/h of Wibro could be enough. Because the moto of Wibro at it's first phase is DSL in outdoor.
The Requirements of Wibro Services;
■ Provide the way to use high speed internet service not only in home but also in outdoor → Equivalent data rate to xDSL per user
■ Maximize the usage over the allocated spectrum
■ Maximize the spectral efficiency
■ Extend the service coverage
■ Reduce the cost per bit
■ Low power consumption at AT
■ Faster handoff
