Xov: yog ipv6-raws li, tsis tshua muaj zog mesh networking thev naus laus zis tsim los muab kev ruaj ntseg, tsis muaj kev sib txuas lus rau Internet ntawm Yam khoom siv.Keeb kwm tsim los rau kev siv lub tsev ntse thiab lub tsev automation xws li kev tswj cov khoom siv hluav taws xob, kev tswj qhov kub thiab txias, kev siv hluav taws xob, teeb pom kev zoo, kev ruaj ntseg, thiab lwm yam, Xov tau nthuav dav nws cov peev txheej kom suav nrog kev siv Internet ntawm Yam Khoom.Vim Thread siv 6LoWPAN thev naus laus zis thiab ua raws li IEEE 802.15.4 mesh networking raws tu qauv, Xov tseem yog tus IP chaw nyob, muab kev sib txuas lus zoo ntawm cov nqi qis, roj teeb uas siv tau zoo li huab thiab AES encryption.
Txhawm rau kom nrawm nrawm ntawm Thread raws tu qauv, Nest Labs (ib lub koom haum ntawm Cov Ntawv / Google), Samsung, ARM, Qualcomm, NXP Semiconductor / Freescale, Silicon Labs thiab lwm lub tuam txhab tsim "Thread Group" alliance nyob rau lub Xya hli ntuj 2014. Xov raws li tus txheej txheem kev lag luam thiab muab cov ntawv pov thawj xov rau cov tswv cuab cov khoom lag luam.
Bluetooth:Tus qauv thev naus laus zis wireless uas siv 2.4-2.485 GHz ISM band UHF xov tooj cua nthwv dej, raws li cov ntaub ntawv packets, nrog rau tus tswv- qhev architecture, kom paub cov ntaub ntawv luv luv ntawm kev sib pauv ntawm cov khoom siv ruaj khov, cov khoom siv txawb thiab tsim kev sib txuas ntawm tus kheej.Tswj los ntawm Bluetooth Technology Alliance (SIG), IEEE teev Bluetooth thev naus laus zis raws li IEEE 802.15.1, tab sis nws tsis tswj hwm tus qauv thiab muaj lub network ntawm patents uas tuaj yeem muab rau cov khoom siv ua raws.Bluetooth siv zaus-hopping thev naus laus zis los faib cov ntaub ntawv xa mus rau hauv pob ntawv uas kis tau sib cais ntau dua 79 txoj hauv Bluetooth.Txhua channel muaj bandwidth ntawm 1 MHz.Bluetooth 4.0 siv 2 MHz suab thiab tuaj yeem haum 40 raws.Lub zoo zoo wireless Bluetooth headset roj teeb yuav kav 2-3 xyoos, feem ntau yog ob peb lub lis piam.
Wi-SUN (Wireless Smart Ubiquitous Network) thev naus laus zis yog ua raws li cov lus qhia qhib ntawm IEEE 802.15.4g, IEEE 802, thiab IETF IPv6 tus qauv.Wi-SUN FAN yog ib qho mesh network raws tu qauv nrog ad-hoc networking thiab kho tus kheej ua haujlwm.Txhua lub cuab yeej hauv lub network tuaj yeem sib txuas lus nrog nws cov neeg nyob ze, thiab cov lus tuaj yeem mus ntev heev ntawm txhua qhov ntawm lub network.Wi-SUN kis tau tus mob thev naus laus zis yog tus cwj pwm los ntawm cov chaw taws teeb sib kis, kev ruaj ntseg, kev ua haujlwm siab, kev sib tshuam, kev tsim kho yooj yim, Mesh network, thiab kev siv hluav taws xob tsawg (Wi-SUN module roj teeb lub neej siv tau ntev li kaum xyoo).Nws yog dav siv hauv kev sib txuas lus xws li cov ntsuas hluav taws xob ntse thiab kev tswj xyuas hluav taws xob hauv tsev (HEMS) tswj.Nws kuj yog qhov tsim nyog los tsim kom muaj qhov dav dav hauv Internet ntawm txhua yam.
Ua txhua yam no ua ke, peb xav tias nws yuav pab tau zoo rau kev lag luam los muab cov txheej txheem luv luv ntawm kev siv cov qauv tsim uas yooj yim los tsim thiab nthuav cov ntaub ntawv kev sib txuas lus kev nyab xeeb kev txiav txim siab.Ntawm ntau tus qauv IEEE 802.15.4, xws li ZigBee Pro, Xov thiab RF4CE, peb pom Xov Tooj muaj peev xwm tshaj plaws rau kev txhim kho rau cov laj thawj hauv qab no: (1) Kev txhawb nqa los ntawm cov tuam txhab loj xws li Google, Arm, thiab Samsung, Apple koom nrog Xov nyob rau hauv 2018. (2) IP-raws li raws tu qauv, kev koom ua ke ntawm software kev sib txuas lus raws tu qauv yog heev yooj yim mus cuag.(3) Cov cuab yeej siv tau zoo heev, muaj kev sib cuam tshuam, muaj kev nyab xeeb thiab tsim nyog rau hom roj teeb uas siv tau.Cov hauv qab no yog cov lus txheeb cais ntawm kev lag luam kev loj hlob kwv yees.
Raws li koj tuaj yeem pom los ntawm daim duab saum toj no, kev txais yuav cov txheej txheem cuam tshuam raws li IEEE 802.15.4 xav tias yuav loj hlob ntxiv, tsom mus rau ZigBee thiab Xov, tshwj xeeb Xov.Nyob rau hauv cov nqe lus ntawm daim ntawv thov, raws li kev sib sau ua ke ntawm cov ntaub ntawv soj ntsuam kev lag luam, Smart Home, Medical Devices, Auto Metering, Smart Building thiab Industrial yog cov ntawv thov tseem ceeb.
