Bluetooth na Wi na Sub

Myezi yiŵiri iyo yajumphapo, unyolo wa masitolo ghakurughakuru gha pakatikati - ku Southern Europe ukatipempha kuti tizunurepo mazgu ghakulembeka pa mashelufu gha pa kompyuta gha masitolo 22. Gulu lawo lakugula likaŵa kuti laŵikika kale ndondomeko zitatu zakupambanapambana - yimoza yikugwiliskira ntchito Bluetooth LE, yinyake pa Wi-Fi, ndipo yinyake pa wayilesi ya 433 MHz. Munthu waliyose uyo wakaguliskanga vinthu wakayowoyanga kuti vyawo ndivyo vikaŵa viwemi chomene. Palije uyo wakalongosora kuti ni mu mikhaliro wuli iyo yikaŵa yiheni comene. Kudumbiskana uku kukapangiska kuti tilembe chigaŵa ichi.

Mabanja ghatatu ghambura waya ghakulamulira kutumizgika kwa ESL sonosono apa: Bluetooth Nkhongono Yichoko (BLE, chomenechomene kufuma pa 5.4), Wi -Fi, na Sub- GHz wayilesi (433 MHz ku Asia, 868 MHz ku Europe, 915 MHz ku North America). Protocol yiliyose yikumazga suzgo leneco. Chilichose chikupanga vyakuguliska ivyo maburosha gha ŵakuguliska ghakuwoneska pasi. Apa pali ivyo tawona mu malo gha masitolo ghanenesko.

Bluetooth LE: Kujulika Muyezo, Kuchali Kukura pa Sikelo

Bluetooth ili na nkhongono zikuru kuseri kwake. Bluetooth SIG yikasindikizga ESL Profile yakujipeleka iyo yikapangika pa Bluetooth 5.4 ya PAwR (Kusaska Nyengo na Nyengo na Mazgoro) iyo yili na - nthowa iyo yikupangiska kuti malo ghamoza ghakunjilirapo ghapharazge malango ku vikwi vya malemba mu nyengo zakunozgeka, ndipo pamanyuma pake ŵakupokera mazgoro gha munthu waliyose kwambura mazgoro.

Silicon Labs wakayezga ivi pa netiweki ya 1,500 mu labotale yawo. EM Microelectronic wakatumizga em|bleu SoC pa 1.8 × 1.8 mm pera na 200 nA yakugona mwakuya sono - yichoko chomene ndiposo yakuchepa mwakukwana kuti yiŵe mukati nanga nkhu2.66-mainchi ya E-ink. Pakuti vipangizo vya Bluetooth vyakujumpha 5 biliyoni vikutumizgika chaka chilichose, mtengo wa vigaŵa ukusanga phindu kufuma ku chuma chikuru chomene.

Kwa ŵakuguliska, chinthu chakuzirwa chomene nkhusinthasintha kwa ŵakuguliska. Muyezo wakujulika ukung'anamura - pafupifupi mu fundo - kuti mungasakanizga malo ghakunjilirapo kufuma kwa wakupeleka yumoza na malemba kufuma kwa munyake. Icho nchifukwa chakuzirwa kufuma ku lock ya ŵakuguliska-mu iyo yasuzga ESL kwa vyaka vinandi. Mafunde ghakugona pasi pa 2 μA ghakumanyikwa na chipsets ya BLE ESL, ndipo Bluetooth 5.4 spec yikukhozgera pafupifupi malemba 32,600 pa netiweki ya malo ghakunjilirapo pa pepala.

Kugwira: "pa pepala" nkhani pano. Kutumizgika kwa vyakurya vikuru- pa BLE kuchali kwachoko chomene pakuyaniska na ndondomeko za mweneko izo zakhala zikuchitika kwa vyaka khumi. Rigado, wakuguliska chipata cha IoT uyo wakugwira ntchito mu ESL, wakuŵika ndalama za chipata pa $ 1,000 kufika pa $ 2,000 zakuŵikika - ndipo sitoro yikuru yingakhumbikwira khumi panji kujumphirapo. BLE yikugwira ntchito pa 2.4 GHz, kugaŵana spectrum na Wi-Fi routers, mafoni gha makasitomala, ma microwave, na chipangizo chilichose chambura waya mu nyumba. Mu sitoro iyo muli ŵanthu ŵanandi, kuzura uku kungapangiska kuti mitengo yileke kusintha pa nyengo iyo ŵanthu ŵakuŵa ŵanandi.

Kuyana makora: ma pharmacy, ma boutiques, na masitolo gha pakati pa-pasi pa 2,000 m2 - chomenechomene awo ŵali kale na BLE beacons kuti ŵalondezge katundu. Ŵakuguliska ŵakupenja5.8-mainchi BLE-wakukwaniska malembo gha pa mashelufukuti update kufuma pa tablet kwambura vipangizo vyakuzirwa vizamusanga kuti protocol iyi njakukondweska.

Wi-Fi: Gwiliskirani nchito Network yinu iyo yilipo - Kweni Bajeti ya Mabatire

Nkhani yake njakunyoloka: sitoro yinu yikugwiliskira kale ntchito Wi-Fi mu msewu uliwose, ntheura lumbani vipata viphya na kulumikizga ma ESL ghinu mwaluŵiro ku netiweki iyo yilipo. Kwa maunyolo ghakuru gha bizinesi agho ghaŵika kale ndalama zinandi mu malo ghakunjilirapo gha malonda na kuvikilira kose, masamu ghakusazga ghakuwoneka ghakukondweska.

Wi-Fi nayo wakupereka data yikuru kuluska BLE panji Sub-GHz. Uwemi uwu ukuwoneka para mukukankhira vithuzithuzi vyakuwoneka makora - vithuzithuzi vya katundu, vithuzithuzi vyakusaska - kuLCD-kukhazikika pa vithuzithuzi vya mitengo ya digitom'malo mwa ma tag gha E-ink ghambura kusuzga. ASikirini ya LCD ya mainchi 15.6kuseŵezeska malonda pa endcap kukukhumba bandwidth iyo E-ink mitengo tags yikukhumba yayi.

Suzgo likuwoneka mu malo ghaŵiri. Chakwamba, kugwiriskira ncito magesi. Wi-Fi yikukopa magesi ghanandi chomene kuluska BLE panji Sub-GHz pa nyengo yiliyose yakutumizga. Lebo ya E-ink pa Sub-GHz radio yingagwira ntchito vyaka vinkhondi panji vinkhondi na vinayi pa selo ya ndalama na kusintha kamoza panji katatu zuŵa lililose. Lembo yimoza pa Wi-Fi? Myezi khumi na yiŵiri mpaka khumi na eyiti. Pa sikelo - vikwi vya ma lebula mu masitolo yanandi - ivyo vikung'anamura kuti pulogiramu yakusintha mabatire yakuwerezgawerezga gulu linu lakugwira ntchito likwenera kusanga. Chachiŵiri, kukhuŵara kwa netiweki. Wi-Fi ESLs yikupikisana pa nyengo ya mlengalenga na ma terminal gha POS, vipangizo vya makasitomala, ma scanner ghakuyegha mu mawoko, na malo ghakujiwonera. Pa nyengo ya nsonga za pa Sabata namise, mpikisano uwo ngwakusambizga waka yayi.

Kuyana makora: ŵamalonda ŵa bizinesi awo ŵali na vyakupangika vya Wi-Fi vyakukhwima, vyakupangika makora, masitolo agho ghakugwira ntchito na vimanyikwiro vya LCD vya digito (apo umoyo wa batire ngwambura kukhumbikwa chifukwa vithuzithuzi vikuŵikika), na kutumizgika kukupimika mu mazana m’malo mwa vikwi khumi vya vimanyikwiro.
