Iyo RAK7248 WisGate chishandiso chinosanganisira Raspberry Pi 4 Model B, RAK2287 iyo inosanganisira GPS module uye Heat Sink yekuita zvirinani uye kupisa kwekupisa kwekupisa. Uye imba yacho inovakwa nealuminium casing.
Kune iyo yekuvaka-mu RAK2287 inoshandisa iyo SX1302 chip kubva kuSemtech iyo yakavakirwa-mukati LoRa concentrator IP musimboti ine simba redhijitari yekugadzira chiratidzo injini. Inokwanisa kugashira kusvika ku8 LoRa mapaketi panguva imwe chete inotumirwa nezvinhu zvakasiyana-siyana zvekuparadzira pamatanho akasiyana uye inowanikwa mumhando dzakasiyana-siyana saka inogona kushandiswa kune emukati mabhendi akajairwa. Iyi yakasarudzika kugona inobvumira kuita inovandudza network architectures advantageous pamusoro pemamwe mapfupi masisitimu. Iyo inoteedzera Raspberry Pi zvakatemwa uye iri nyore kukwira neRaspberry Pi uye RAK2287 module.
WisGate yakanakira prototyping, humbowo-hwe-chirevo kuratidzira kana yekuongorora. Inosanganisira yakagadzirira kushandisa LoRaWan Gateway OS inogona kubatana neLoRaWan server. Zvakare inovandudza hushamwari uye yakapusa kunyangwe kune-no-so-techy vashandisi kuseta LoRaWan system. Inofanirwa kuve yakakosha kukosha uye basa rekubatanidza kugadzirisa akasiyana maapplication seSmart Grid, Intelligent Farm uye mamwe maIoT bhizinesi maapplication.
