The amendment supports aggregate data rates greater than the maximum data rate supported by the IEEE Std 802.22-2011. This amendment defines new classes of IEEE 802.22(TM) devices to address these applications and supports more than 512 devices in a network. This amendment also specifies techniques to enhance communications among the devices and makes necessary amendments to the cognitive, security, and parameters and connection management clauses. This amendment supports mechanisms to enable coexistence with other IEEE 802(R) systems in the same band. 606 $aWireless sensor networks 615 0$aWireless sensor networks. 676 $a681.2 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279528503316 996 $aISO$91086301 997 $aUNISA LEADER 01334nam2 22003493i 450 001 UBO0260631 005 20251003044418.0 010 $a8477110522 100 $a20140319d1995 ||||0itac50 ba 101 | $aspa 102 $aes 181 1$6z01$ai $bxxxe 182 1$6z01$an 200 1 $aLibro de ejercicios$fFrancisca Castro Viudez, Soledad Rosa Munoz 205 $a2. ed 210 $aMadrid$cEdelsa grupo didascalia$d1995 215 $a64 p.$d26 cm. 461 1$1001UBO0260619$12001 $aVEN 3$ecurso de espanol para extranjeros$fFrancisca Castro Viudez, Soledad Rosa Munoz 606 $aLINGUA SPAGNOLA$xMANUALI PER STRANIERI$2FIR$3MILC017563$9I 676 $a468.2451$9$v21 696 $aStranieri$aManuali 699 $aManuali per stranieri$xStranieri$xManuali 700 1$aCastro Viudez$b, Francisca$3TO0V168080$4070$0305216 701 1$aMunoz$b, Soledad Rosa$3UBOV104197$4070$0438103 790 1$aCastro$b, Francisca$3UBOV113425$zCastro Viudez, Francisca 801 3$aIT$bIT-000000$c20140319 850 $aIT-BN0095 912 $aUBO0260631 950 2$aBiblioteca Centralizzata di Ateneo$c1 v.$d 01LT (AR) 16 B 442$e 01AR 0700164425 VMA 1 v.$fB $h20140319$i20140319 977 $a 01 996 $aLibro de ejercicios$967816 997 $aUNISANNIO
