The book offers a comprehensive understanding of the options available for teams tasked with bringing 5G products and services to market or developing supporting standards and regulatory frameworks. Readers find contemporary examples of millimeter band radio hardware including 60 GHz and V band and E Band point to point radio. This book demonstrates the profound progress with 4G radio signal processing and RF hardware to reveal its potential applicability to 5G radio systems. It shows how 5G systems are capable of delivering data rates that are ten to one hundred times faster than 4G systems. Developments in spatial processing and beam forming in local area radio networks are presented and the challenge of scaling these systems to wide area radio is explored. This book reviews military and space radio and automotive radar innovation with direct relevance to 5G radio design. 410 0$aArtech House mobile communications series. 517 3 $aFiveG spectrum and standards 517 3 $aFifth generation spectrum and standards 606 $aMobile communication systems 606 $aWireless communication systems 606 $aCell phone systems$xStandards 615 0$aMobile communication systems. 615 0$aWireless communication systems. 615 0$aCell phone systems$xStandards. 676 $a621.38456 700 $aVarrall$b Geoffrey$01688512 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910821789603321 996 $a5g spectrum and standards$94099162 997 $aUNINA
