Ukuzenzekela kwekhaya kuxhaphakile kule mihla. Kukho iiprotokholi ezininzi ezahlukeneyo ezingenazingcingo, kodwa ezo abantu abaninzi bazivayo yiWiFi kunye neBluetooth kuba ezi zisetyenziswa kwizixhobo esinazo uninzi lwethu, iifowuni eziphathwayo kunye neekhompyutha. Kodwa kukho enye indlela ebizwa ngokuba yiZigBee eyenzelwe ukulawula kunye nezixhobo. Into enye abafana ngayo bonke abathathu kukuba basebenza malunga ne-frequency efanayo - kwi-2.4 GHz okanye malunga nayo. Ukufana kuphelela apho. Ngoko ke yintoni umahluko?

I-WIFI

I-WiFi ithatha indawo yentambo ye-Ethernet eneentambo kwaye isetyenziswa kwiimeko ezifanayo ukuthintela ukusebenzisa iingcingo kuyo yonke indawo. Inzuzo enkulu ye-WiFi kukuba uya kukwazi ukulawula nokujonga uluhlu lwezixhobo ezikrelekrele zekhaya lakho ukusuka naphi na emhlabeni ngefowuni, ithebhulethi, okanye ilaptop. Kwaye, ngenxa yokuba i-Wi-Fi ixhaphake kakhulu, kukho uluhlu olubanzi lwezixhobo ezikrelekrele ezinamathela kulo mgangatho. Oku kuthetha ukuba iPC akufuneki ishiywe ivuliwe ukuze ifikelele kwisixhobo usebenzisa i-WiFi. Iimveliso zokufikelela kude ezifana neekhamera ze-IP zisebenzisa i-WiFi ukuze ziqhagamshelwe kwi-router kwaye zifikeleleke kwi-Intanethi. I-WiFi iluncedo kodwa ayilula ukuyisebenzisa ngaphandle kokuba ufuna nje ukuqhagamshela isixhobo esitsha kwinethiwekhi yakho ekhoyo.

Ingxaki kukuba izixhobo ezikrelekrele ezilawulwa yi-Wi-Fi zibiza kakhulu kunezo zisebenza phantsi kweZigBee. Xa kuthelekiswa nezinye iindlela, i-Wi-Fi ifuna umbane kakhulu, ngoko ke oko kuya kuba yingxaki ukuba ulawula isixhobo esikrelekrele esisebenza ngebhetri, kodwa akukho ngxaki konke konke ukuba isixhobo esikrelekrele sifakwe kwi-house current.

I-BLUTOOTH

Ukusetyenziswa kwamandla aphantsi kwe-BLE (bluetooth) kufana nombindi we-WiFi eneZigbee, zombini zinamandla aphantsi eZigbee (ukusetyenziswa kwamandla kuphantsi kuneeWiFi), iimpawu zokuphendula ngokukhawuleza, kwaye zinenzuzo yokusebenzisa iWiFi ngokulula (ngaphandle kwesango kunokuqhagamshelwa iinethiwekhi zeselfowuni), ngakumbi xa kusetyenziswa iifowuni eziphathwayo, ngoku njengeWiFi, iprotocol yeBluetooth iba yiprotocol eqhelekileyo kwifowuni ehlakaniphileyo.

Isetyenziswa ngokubanzi kunxibelelwano oluya kwindawo enye, nangona iinethiwekhi zeBluetooth zinokusekwa ngokulula. Ii-applications eziqhelekileyo esizaziyo sonke zivumela ukudluliselwa kwedatha ukusuka kwiifowuni eziphathwayo ukuya kwiiPC. I-Bluetooth wireless yeyona sisombululo silungileyo kwezi linki ze-point to point, njengoko inamazinga aphezulu okudluliselwa kwedatha kwaye, nge-antenna efanelekileyo, ithatha ixesha elide kakhulu ukuya kwi-1KM kwiimeko ezifanelekileyo. Inzuzo enkulu apha kuqoqosho, njengoko kungekho zi-routers okanye iinethiwekhi ezahlukeneyo ezifunekayo.

Enye ingxaki kukuba iBluetooth, eyona nto iphambili kuyo, yenzelwe ukunxibelelana nabantu abakufutshane, ngoko ke unokuchaphazela kuphela ulawulo lwesixhobo esikrelekrele ukusuka kuluhlu olukufutshane. Enye kukuba, nangona iBluetooth ibikho kangangeminyaka engaphezu kwama-20, isandul’ ukungena kwi-smart home arena, kwaye okwangoku, abenzi abaninzi baye bafikelela kwinqanaba elifunekayo.

I-ZIGBEE

Kuthekani nge-ZigBee wireless? Le yiprotokholi engenazingcingo esebenza nakwibhendi ye-2.4GHz, njengeWiFi kunye neBluetooth, kodwa isebenza ngamaxabiso edatha aphantsi kakhulu. Iingenelo eziphambili ze-ZigBee wireless zezi

• Ukusetyenziswa kwamandla aphantsi
• Inethiwekhi eyomeleleyo kakhulu
• Ukuya kuthi ga kwi-65,645 nodes
• Kulula kakhulu ukongeza okanye ukususa ii-nodes kwinethiwekhi

I-Zigbee njengeprotokholi yonxibelelwano olungenazingcingo yomgama omfutshane, ukusetyenziswa kwamandla aphantsi, inzuzo enkulu kukuba inokwenza ngokuzenzekelayo izixhobo zenethiwekhi, ukuhanjiswa kwedatha kwezixhobo ezahlukeneyo eziqhagamshelwe ngqo, kodwa kufuneka kubekho iziko kwi-node yenethiwekhi ye-AD hoc ukulawula inethiwekhi yeZigbee, oko kuthetha ukuba izixhobo zeZigbee kwinethiwekhi kufuneka zibe nezinto ezifanayo "ne-router", zidibanise isixhobo kunye, ziqonde isiphumo sonxibelelwano lwezixhobo zeZigbee.

Le nxalenye yongezelelweyo "ye-router" yinto esiyibiza ngokuba yi-gateway.

Ukongeza kwiingenelo, iZigBee ikwanazo neengxaki ezininzi. Kubasebenzisi, kusekho umda wokufakwa kweZigBee, kuba uninzi lwezixhobo zeZigBee azinalo isango lazo, ngoko ke isixhobo esinye seZigBee asinakulawulwa ngokuthe ngqo yifowuni yethu ephathwayo, kwaye isango liyafuneka njengehabhu yonxibelelwano phakathi kwesixhobo kunye nefowuni ephathwayo.

Ungasithenga njani isixhobo sasekhaya esikrelekrele phantsi kwesivumelwano?

Ngokubanzi, imigaqo yeprotocol yokukhetha izixhobo ezikrelekrele yile ilandelayo:

1) Kwizixhobo ezixhunyiweyo, sebenzisa iprotocol ye-WIFI;

2) Ukuba ufuna ukusebenzisana nefowuni ephathwayo, sebenzisa i-BLE protocol;

3) I-ZigBee isetyenziselwa izinzwa.

Nangona kunjalo, ngenxa yezizathu ezahlukeneyo, izivumelwano ezahlukeneyo zezixhobo zithengiswa ngaxeshanye xa umenzi ehlaziya izixhobo, ngoko ke kufuneka siqwalasele la manqaku alandelayo xa sithenga izixhobo zasekhaya ezikrelekrele:

1. Xa uthenga “I-ZigBee"Isixhobo, qiniseka ukuba unayoIsango leZigBeeekhaya, kungenjalo uninzi lwezixhobo zeZigBee ezizimeleyo azinakulawulwa ngqo kwifowuni yakho ephathwayo.

2.Izixhobo ze-WiFi/BLE, uninzi lwezixhobo zeWiFi/BLE zinokuqhagamshelwa ngqo kwinethiwekhi yefowuni ephathwayo ngaphandle kwesango, ngaphandle kwenguqulelo yeZigBee yesixhobo, kufuneka zibe nesango lokuxhuma kwifowuni ephathwayo. Izixhobo zeWiFi kunye neBLE azinyanzelekanga.

3. Izixhobo ze-BLE zihlala zisetyenziselwa ukusebenzisana neefowuni eziphathwayo xa zikufutshane, kwaye isignali ayilunganga emva kodonga. Ke ngoko, akukhuthazwa ukuthenga iprotocol ye-BLE "kuphela" kwizixhobo ezifuna ulawulo olukude.

4. Ukuba i-router yasekhaya yi-router eqhelekileyo yasekhaya, akukhuthazwa ukuba izixhobo zasekhaya ezikrelekrele zisebenzise i-protocol ye-WIFI ngobuninzi, kuba kusenokwenzeka ukuba isixhobo siya kuhlala singaxhunyiwe kwi-intanethi. (Ngenxa yokufikelela okulinganiselweyo kwii-routers eziqhelekileyo, ukufikelela kwizixhobo ezininzi ze-WIFI kuya kuchaphazela uqhagamshelo oluqhelekileyo lwe-WIFI.)
