Mwedzi miviri yapfuura, zvitoro zvikuru zvepakati-muSouthern Europe zvakatikumbira kuti titore masherufu esherufu yemagetsi pazvitoro makumi maviri nemaviri. Chikwata chavo chekutenga zvinhu changa chatoiswa masisitimu matatu akasiyana - imwe inoshandisa Bluetooth LE, imwe paWi-Fi, uye imwe paredhiyo ye433 MHz. Mumwe nemumwe mutengesi aiti yavo ndiyo yaive yakanyanya kunaka. Hapana akatsanangura kuti zvakanga zvanyanya kuipisisa mumamiriro api. Hurukuro iyoyo yakatikurudzira kunyora chidimbu ichi.
Mhuri nhatu dzisina waya dzeprotocol dziri kutonga kushandiswa kweESL izvozvi: Bluetooth Low Energy (BLE, kunyanya kubva ku5.4 yakatarwa), Wi-Fi, uye Sub-GHz redhiyo (433 MHz kuAsia, 868 MHz muEurope, 915 MHz kuNorth America). Imwe neimwe protocol inogadzirisa dambudziko chairo. Imwe neimwe inogadzira tradeoffs iyo mutengesi mabhurocha ari pasi pekutamba. Hezvino zvatakaona munzvimbo dzese dzezvitoro chaidzo.
Bluetooth LE: Vhura Standard, Ichiri Kukura paChikero
Bluetooth ine kusimba kwakakomba kumashure kwayo. Iyo Bluetooth SIG yakaburitsa yakatsaurirwa ESL Profile yakavakirwa paBluetooth 5.4's PAwR (Periodic Advertising with Responses) inoratidzira - dhizaini inoita kuti imwe nzvimbo yekupinda itepfenyure mirairo kuzviuru zvemavara munzvimbo dzakarongeka dzenguva, wozogamuchira mhinduro pasina kumisikidza kubatanidza kwega.
Silicon Labs yakaedza izvi pa1,500-node network mulab yavo. EM Microelectronic yakatumira iyo em|bleu SoC pa 1.8 × 1.8 mm ine 200 nA yakadzama yekurara ikozvino - idiki yakakwana uye isina kusimba zvakakwana kuti ikwane mukati.compact 2.66-inch E-ink tags. Neanopfuura mabhiriyoni mashanu emidziyo yeBluetooth inotumirwa gore negore, mari yechikamu inobatsirwa nehupfumi hukuru hwechiyero.
Kune vatengesi, iyo inoshanda kumusoro ndeye mutengesi kushanduka. Muyero wakavhurika unoreva - zvirinani mumusimboti - kuti unokwanisa kusanganisa nzvimbo dzekusvikirwa kubva kune mumwe mutengesi ane mavara kubva kune mumwe. Uku ndiko kusimuka zvine mutsindo kubva kukiyi yemutengesi-mune iyo yanetsa ESL kwemakore. Kurara pazasi 2 µA kwakajairwa neBLE ESL chipsets, uye iyo Bluetooth 5.4 spec inotsigira angangoita 32,600 mavara pane yekuwana nzvimbo network pabepa.
Kubata: "papepa" zvine basa pano. Huru-kutumirwa kwegrocery paBLE kuchiri kudiki kana zvichienzaniswa nemasisitimu evaridzi anga achishanda kwemakore gumi. Rigado, mutengesi wepasuo reIoT anoshanda muESL, anoisa mutengo wepagedhi pamadhora chiuru kusvika kumadhora maviri akaiswa - uye chitoro chikuru chingada gumi kana kudarika. BLE inoshanda pa 2.4 GHz, ichigoverana spectrum neWi{{10}Fi routers, nharembozha dzevatengi, mamicrowave, uye zvimwe zvese zvishandiswa zvisina waya muchivako. Muchitoro chakabatikana, kuungana ikoko kunogona kunonoka kugadziridzwa kwemitengo panguva dzepamusoro.
Zvakanakisa: zvitoro zvemishonga, zvitoro, nepakati-zvitoro zvesaizi zviri pasi pe2,000 m² - kunyanya zviya zvave kutoshandisa mabhakoni eBLE ekuronda zvinhu.

Wi-Fi: Shandisa Network Yako Yavepo - Asi Budget yemabhatiri
Chimiro chakatwasanuka: chitoro chako chatova nebhizinesi Wi{{0}Fi mugwara rega rega, saka svetuka magedhi matsva uye ubatanidze maESL ako kunetiweki iripo. Kune macheni makuru emabhizinesi akatoisa mari yakawandisa munzvimbo dzekutengesa nekuvhara yakazara, iyo yekubatanidza math inotaridzika inoyevedza.
Wi-Fi inopawo ruzivo rwepamusoro kupfuura BLE kana Sub-GHz. Mubairo iwoyo unobatika kana iwe uchisaidzira hupfumi hwemifananidzo - mifananidzo yechigadzirwa, mifananidzo yekusimudzira -LCD-based digital price screenskwete maE-ink tags.

Dambudziko rinoonekwa munzvimbo mbiri. Kutanga, kushandiswa kwesimba. Wi-Fi inodhirowa zvazvino kupfuura BLE kana Sub-GHz panguva yega yega yekufambisa. E{{5}ink label paSub-GHz redhiyo inogona kuita makore mashanu kusvika masere pasero rekoini rine imwe kusvika kumatatu emazuva ese. Iro zita rimwechete paWi{{8}Fi? Mwedzi gumi nemiviri kusvika gumi nemisere. Pachiyero - zviuru zvemalebula muzvitoro zvakawanda - zvinoreva kuti chirongwa chinodzokororwa chekuchinja bhatiri chinofanirwa kushandiswa nechikwata chako. Chechipiri, network congestion.

Zvakanakisisa: vatengesi vane ruzivo,{0}}zvakagadzirwa neWiFi{1}Fi zvivakwa, zvitoro zvine magetsi eLCD masaini edhijitari (apo hupenyu hwebhatiri husina basa nekuti masikirini akavharirwa), uye kushandiswa kuyerwa mumazana kwete makumi ezviuru emalebula.
Sub-GHz (433/868/915 MHz): Hapana Kuyevedza, Kureba, Bhatiri refu
Sub{{0}GHz redhiyo haina sangano rinoshambadza rinoisimudzira sematambi eBluetooth SIG BLE. Mazhinji Sub{{2} GHz ESL masisitimu anomhanyisa maprotocol anoenderana nemugadziri wemazita. Iko hakuna kudyidzana profile. Kushandura vatengesi kunoreva kutsiva iyo yese yekutaurirana stack.
Uye zvakadaro, kune mamwe mafomati ezvitoro, iyo fizikisi inoita kuti ive sarudzo inonyanya kushanda. Lower frequencies inogadzira wavelengths yakareba. Marefu marefu anopinda masherufu esimbi, kongiri yekuparadzanisa madziro, uye mafiriji ekuratidzira makesi zvinobudirira kupfuura 2.4 GHz masaini. Display Data, UK{{4}based ESL provider, vakavaka chikuva chavo chese paSub-1 GHz nokuda kwechikonzero ichi - hukuru hwehuwandu uye masaini ekupinda munzvimbo dzakaoma dzezvitoro. Nzvimbo imwe chete yeSub-GHz yekupinda inovhara tsoka yakakura kudarika yayo BLE kana Wi-Fi yakaenzana. Nzvimbo shoma dzekuwana dzinoreva kuderera kwemutengo wezvivakwa uye nyore kuronga network.
Upenyu hwebhatiri ndicho chimwe chinhu chakakosha. Silicon Labs 'ESL dhizaini dhizaini inotsanangura kuti kusvika makore mashanu kusvika gumi paCR2032 coin cell zvinoda avhareji yazvino bhajeti pazasi 10 µA - yavo Sub-GHz FG22 SoC inowana 0.17 µA mukurara kukuru.
