WMBus ke eng?
WMBus, kapa Wireless M-Bus, ke protocol ea puisano e se nang mohala e emeng tlasa EN 13757, e etselitsoeng ho bala ka boiketsetso le hole.

E sebetsa haholo sehlopheng sa 868 MHz ISM, WMBus e ntlafalitsoe bakeng sa:
Tšebeliso e tlaase ea matla

WMBus e ts'ehetsa encryption ea AES-128 le ho lemoha liphoso tsa CRC, ho netefatsa phetiso ea data e bolokehileng le e nepahetseng.
Mekhoa e mengata ea ts'ebetso
WMBus e fana ka mekhoa e mengata ea ho ts'ehetsa lits'ebetso tse fapaneng:
S-Mode (Stationary): Lisebelisoa tse tsitsitseng

WMBus e sebetsa joang?
Limithara tse nolofalitsoeng ke WMBus li romela lipakete tsa data tse kentsoeng ka linako tse reriloeng ho moamoheli—ebang ke selefouno (bakeng sa ho bokelloa ha koloi) kapa tse tsitsitseng (ka tsela ea heke kapa sekontiri). Hangata lipakete tsena li kenyelletsa:
Lintlha tsa tšebeliso

Lintlha tse bokelletsoeng li fetisetsoa ho sistimi e bohareng ea taolo ea data bakeng sa ho lefisa, ho sekaseka le ho beha leihlo.
WMBus e sebelisoa Hokae?
WMBus e amoheloa haholo Europe bakeng sa metering ea lisebelisoa tse bohlale. Likarolo tse tloaelehileng tsa tšebeliso li kenyelletsa:
Limithara tse bohlale tsa metsi litsamaisong tsa masepala
Limithara tsa khase le mocheso bakeng sa marang-rang a futhumatsang setereke
Limithara tsa motlakase meahong ea bolulo le ea khoebo
Hangata WMBus e khethoa bakeng sa libaka tsa litoropo tse nang le lisebelisoa tsa metering tse teng, ha LoRaWAN le NB-IoT li ka khethoa libakeng tse tala kapa libakeng tsa mahaeng.
Melemo ea ho Sebelisa WMBus
Ts'ebetso ea Battery: Nako e telele ea nako ea lisebelisoa
Ts'ireletso ea data: Ts'ehetso ea encryption ea AES
Khokahano e Bonolo: Puisano e bulehileng e thehiloeng maemong
Flexible Deployment: E sebetsa bakeng sa marang-rang a mobile le a tsitsitseng
TCO e ka tlaase: E theko e tlaase ha e bapisoa le litharollo tse thehiloeng ho cellular
E fetoha le Mmaraka: WMBus + LoRaWAN Dual-Mode
Baetsi ba limithara ba bangata hona joale ba fana ka li-module tse peli tsa WMBus + LoRaWAN, tse lumellang ts'ebetso e se nang moeli ho li-protocol ka bobeli.
