Consumer communication applications drive network integration [Series Editorial]

This theme is strongly reflected in the four articles we have selected for this edition of the Consumer Communications and Networking series. The theme includes the integration of network features as well as new application and network integration. The first article in this edition, by Stuart Jacobs, focuses on the authentication mechanisms in WiMAX-based metropolitan networks. It discusses how digital certificates are handled and highlights the lack of multiple certificate authority support as an issue that prevents the interoperability of WiMAX devices from different manufacturers.
