rea and personal-area radio systems. Admission control algorithms can be based on channel availability, channel quality and channel 'cost' that in an ideal world could be reflected in a 'blended tariff' structure to maximise revenues and margin in combination with a more consistent (and hence higher value) user proposition. When combined with other downlink delivery options such as DAB, DVB, these 'blended bandwidth' offerings are sometimes described in the technical literature as 'cooperative net- works'. The technical and potential cost benefits of such schemes are compelling but adoption is de- pendent on the resolution of conflicting commercial objectives. The fiscal aims of cooperation and competition rarely coincide unless a certain amount of coercion is used. 'Balanced bandwidth' essentially involves achieving a network balance between radio access bandwidth, buffer bandwidth in the end-to-end channel, (including IP RAN and IP core memory bandwidth distribution), persistent storage bandwidth and server bandwidth and being able to manage this bandwidth mix proactively to match rapidly changing traffic loading and user-application requirements. 21.8.1 How Super Phones Contribute to Competitive Network Value We have already stated that existing phones and mobile broadband devices play a key role in collecting the contextual information needed to support power control and handover and admission control algorithms. Power control, handover and admission control algorithms are needed to deliver power efficiency (which translates into more offered traffic per battery charge) and spectral effi- ciency (which translates into a higher return on investment per MHz of allocated or auctioned spectrum). 21.8.2 Phones are the Eyes and Ears of the Network However, we also suggested that there are three categories of phone, standard phones, smart phones and super phones. Standard phones are voice and text dominant and change the way we relate to one another. Smart phones aspire to change the way we organise our work and soc
