Foreword

Summary

It is not so long ago that links in a wired network were not able to cooperate freely but were subject to central control by ISDN and ATM protocols. We now live in a world where Internet protocols have made it possible for networks to grow like weeds. We take it for granted that links should regulate their own use by generating prices that reflect congestion and that users adjust rates in response to the cost of traversing the network.

The IP revolution that has transformed the wireline world is coming to wireless. Migration from cellphones to smartphones has created demand for capacity that simply cannot be met by circuit switched networks engineered to provide worst case coverage at the cell boundary. This is a monograph written by revolutionaries that maps the new world of what is possible when wireless resources are properly shared.

The monograph is remarkable for starting with services, with medium access, and then asking how to engineer the physical layer that the higher layers want to see. The authors answered this question themselves by making a journey from concept to working system and then staging field trials. This monograph is the result of a virtuous cycle where engineering challenges led to theoretical insights and new theory was proved out in working systems.
