Architecture of a Wireless Wide-Area Network (WWAN) 330 $aThis book provides comprehensive coverage of mobile data networking and mobile communications under a single cover for diverse audiences including managers, practicing engineers, and students who need to understand this industry. In the last two decades, many books have been written on the subject of wireless communications and networking. However, mobile data networking and mobile communications were not fully addressed in a unified fashion. This book fills that gap in the literature and is written to provide essentials of wireless communications and wireless networking, including Wireless Pe 410 0$aMorgan Kaufmann series in networking. 606 $aWireless communication systems 606 $aWireless LANs 608 $aElectronic books. 615 0$aWireless communication systems. 615 0$aWireless LANs. 676 $a621.382/1 700 $aGarg$b Vijay Kumar$f1938-$027633 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910458656403321 996 $aWireless communications and networking$91916378 997 $aUNINA LEADER 01179nam a2200301 i 4500 001 991001698529707536 005 20020502200145.0 008 941215s1994 it ||| | ||| 035 $ab10893398-39ule_inst 035 $aLE02374784$9ExL 040 $aDip.to Studi Storici$bita 082 0 $a320.945 100 1 $aBidussa, David$0125177 245 13$aIl mito del bravo italiano :$bpersistenza, caratteri e vizi di un paese antico/moderno, dalle leggi razziali all'italiano del Duemila /$cDavid Bidussa 260 $aMilano :$bIl Saggiatore,$c1994 300 $a110 p. ;$c19 cm. 490 0 $aBiblioteca delle Silerchie ;$v151 650 4$aAntisemitismo$zItalia$y1938-1945 650 4$aEbrei$zItalia$xLegislazione$y1938-1942 650 4$aRazzismo$zItalia 650 4$aVita politica e sociale$zItalia$y1930-1994 651 4$aItaliani$y1990-1994 907 $a.b10893398$b23-02-17$c28-06-02 912 $a991001698529707536 945 $aLE023 320.945 BID 1 1$g1$i2023000031629$lle023$o-$pE0.00$q-$rl$s- $t0$u2$v0$w2$x0$y.i10999851$z28-06-02 996 $aMito del bravo italiano$9917232 997 $aUNISALENTO 998 $ale023$b01-01-94$cm$da $e-$feng$git $h3$i1
