Spectrum efficiency, energy saving, and security are still foundational issues to tackle [Message From The Editor In Chief]

Dear readers, In 2012 IEEE Wireless Communications received a record high number of submissions. This big increase in submissions was due mainly to the use of Manuscript Central and the all-web-based submission-to-publication process, which contributes to a significant reduction of time needed to process submitted papers. As Editor-in-Chief of this magazine, I am very pleased to see this and would like to ensure you that we will do all our best to commit to timely publication of your research results in this prestigious magazine.
