I-LOT isingeniso somhlaba ezindinganisweni zokuxhumana

Uchungechunge: ubuchwepheshe benethiwekhi obusekelwe ku-ipv6, obunamandla aphansi obudizayinelwe ukunikeza ukuxhumana okuphephile, okungenazihibe kumadivayisi we-inthanethi Yezinto.Ekuqaleni yakhelwe izinhlelo zokusebenza ezizenzakalelayo zekhaya elihlakaniphile nokwakha njengokuphatha izinto zikagesi, ukulawula izinga lokushisa, ukusetshenziswa kwamandla, ukukhanyisa, ukuphepha, nokunye okwengeziwe, i-Thread inwebise ububanzi bayo ukuze ifake izinhlelo zokusebenza ze-inthanethi yezinto ezibanzi.Ngenxa yokuthi i-Thread isebenzisa ubuchwepheshe be-6LoWPAN futhi isekelwe kuphrothokholi yenethiwekhi ye-IEEE 802.15.4, i-Thread futhi iyaphenduleka nge-IP, inikeza ukuxhumana okuphumelelayo phakathi kwamadivayisi angabizi kakhulu, asebenza ngebhethri kanye nokubethela kwefu kanye ne-AES.

Ukuze kusheshiswe ukuduma kwephrothokholi yochungechunge, i-Nest Labs (inkampani ephethwe yi-Alphabet/Google), i-Samsung, i-ARM, i-Qualcomm, i-NXP Semiconductor/Freescale, i-Silicon Labs nezinye izinkampani zakha umfelandawonye "we-Thread Group" ngoJulayi 2014. Intambo njengezinga lemboni futhi inikeze isitifiketi se-Thread semikhiqizo yebhizinisi elilungu.

I-Bluetooth:Izinga lobuchwepheshe obungenawaya elisebenzisa i-2.4-2.485 GHz ISM ibhendi ye-UHF yamaza omsakazo, asekelwe kumaphakethe edatha, anesakhiwo esiyisigqila esiyinhloko, ukuthola ukushintshana kwedatha yebanga elifushane phakathi kwamadivayisi angashintshi, amadivaysi eselula nokwakha amanethiwekhi esizinda somuntu siqu.Iphethwe i-Bluetooth Technology Alliance (SIG), i-IEEE ibala ubuchwepheshe be-Bluetooth njenge-IEEE 802.15.1, kodwa ayisagcini izinga futhi inoxhaxha lwamalungelo obunikazi angakhishelwa amadivayisi athobelayo.I-Bluetooth isebenzisa ubuchwepheshe be-frequency-hopping ukuze ihlukanise idatha edlulisiwe ibe amaphakethe adluliswa ngokuhlukile kumashaneli e-Bluetooth angama-79 amisiwe.Isiteshi ngasinye sinomkhawulokudonsa ongu-1 MHz.I-Bluetooth 4.0 isebenzisa 2 MHz pitch futhi ingamukela iziteshi ezingama-40.Ibhethri ye-headphone ye-Bluetooth yekhwalithi enhle izohlala iminyaka engu-2-3, ngokuvamile amaviki ambalwa.

Ubuchwepheshe be-Wi-SUN (Wireless Smart Ubiquitous Network) busekelwe ekucacisweni okuvulekile kwamazinga e-IEEE 802.15.4g, IEEE 802, kanye ne-IETF IPv6.I-Wi-SUN FAN iyiphrothokholi yenethiwekhi ye-mesh enenethiwekhi ye-ad-hoc nemisebenzi yokuziphilisa.Idivayisi ngayinye ekunethiwekhi ingaxhumana nomakhelwane bayo, futhi imilayezo ingahamba amabanga amade kakhulu phakathi kwenodi ngayinye kunethiwekhi.Ubuchwepheshe bokudlulisa i-Wi-SUN bubonakala ngokudluliswa kweremothi, ukuphepha, ukukala okuphezulu, ukusebenzisana, ukwakhiwa okulula, inethiwekhi ye-Mesh, kanye nokusetshenziswa kwamandla okuphansi (imojula ye-Wi-SUN impilo yebhethri ingasetshenziswa iminyaka eyishumi).Isetshenziswa kakhulu kumadivayisi okuxhumana afana namamitha kagesi ahlakaniphile nezilawuli zokuphathwa kwamandla ahlakaniphile ekhaya (HEMS).Kuyasiza futhi ekwakheni i-inthanethi yezinga elikhulu lezinto.

Uma sihlanganisa konke lokhu, sicabanga ukuthi kungaba usizo kakhulu embonini ukunikeza isethi yamamojula wereferensi yebanga elifushane okulula ukuwathuthukisa futhi afake ukucatshangelwa kokuphepha kokuxhumana kwedatha.Phakathi kwamazinga amaningi e-IEEE 802.15.4, afana ne-ZigBee Pro, i-Thread ne-RF4CE, sithola i-Thread inamandla amakhulu okuthuthukiswa ngenxa yalezi zizathu ezilandelayo: (1) Isekelwe izinkampani ezinkulu ezifana ne-Google, i-Arm, ne-Samsung, i-Apple yajoyina Uchungechunge ngo-2018. (2) Iphrothokholi esekwe ku-IP, ukuhlanganiswa kwephrothokholi yokuxhumana kwesoftware kulula kakhulu ukuyifinyelela.(3) Amadivayisi asezingeni eliphezulu, asebenzisana kakhulu, avikeleke kakhulu futhi afanele imodi esebenza ngebhethri.Okulandelayo yithebula lezibalo lesibikezelo sokuthuthukiswa kwemakethe.

Njengoba ungabona eshadini elingenhla, ukwamukelwa kwezivumelwano ezihlobene ngokusekelwe ku-IEEE 802.15.4 kulindeleke ukuthi kuqhubeke ukukhula, kugxile ku-ZigBee ne-Thread, ikakhulukazi i-Thread.Mayelana nesicelo, ngokuya ngokuqoqwa kwedatha yocwaningo lwemakethe, i-Smart Home, Amadivayisi Ezokwelapha, I-Auto Metering, I-Smart Building kanye ne-Industrial yizinkambu ezisetshenziswa kakhulu.
