An advanced air interface-another point of view

It is desirable to have a single air interface applicable to the objectives of both indoor and outdoor environments. In reality, there are some air interfaces that can operate in all environments. The problem is that no air interface can meet the breadth of the requirements put forth for each of the envisioned environments. This paper suggests we need to develop a strategy for generating air interface solutions that are market driven as well as technology driven. Expected market requirements to date range from local loop alternatives, wireless pay phone alternatives, and pedestrian low mobility systems, to office and high mobility vehicular systems. These systems require higher data rate capability along with “good” voice quality, An overriding consideration is that these systems can also utilize a rapidly advancing telecommunications network and emerging cable networks. A new air interface must be able to grow as new applications emerge. This paper suggests that the solution may be a system of compatible air interfaces rather than a single air interface
