Dynamic spectrum management: the technology harvesting the underutilized spectrum resource [Message from the Editor-in-Chief]

摘要

Dear Readers, I hope you have endured the hot summer weather. Well, this has given you more opportunity to read our magazine! Just because you stay inside the cooling zones, this may leave much more spectrum underutilized in some outdoor areas. If the idling licensed spectra can be opportunistically utilized by others, we could enrich people¿s lives by using the unused spectrum resource for other good cause; for example, we might gather more data with better communications systems to resolve the recent oil spill problem in the Gulf!
