Litlhaloso tsa Tekheniki le Tlhahlobo ea Kopo ea Maemo a Phethahatso a Phethahatso

E le sesebelisoa sa bohlokoa lipuisanong tsa marang-rang, batho ba pheta-phetang haholo-holo ba atolosa libaka tsa phetisetso ea marang-rang ka ho matlafatsa kapa ho tsosolosa matšoao, ho netefatsa hore phetiso ea data e ka tšeptjoang libakeng tse rarahaneng. Ho netefatsa ts'ebetso e pheta-phetoang, ho tsamaellana le polokeho, litekanyetso tse ngata tsa ts'ebetso li thehiloe lefats'eng ka bophara, tse akaretsang litšobotsi tsa motlakase, ts'ehetso ea protocol, khokahano ea motlakase (EMC) le litlhoko tsa ts'epo.

Mabapi le ts'ebetso ea motlakase, ba pheta-phetoang ba tlameha ho latela litekanyetso tse amehang ho tsoa ho International Electrotechnical Commission (IEC) le International Telecommunication Union (ITU). Mohlala, letoto la IEC 60068 le sebetsana le liteko tsa maemo a tikoloho, ho netefatsa ts'ebetso e tsitsitseng tlasa maemo a feteletseng joalo ka mocheso o phahameng le o tlase le mongobo. Ho feta moo, litekanyetso tsa sehokelo sa motlakase joalo ka IEEE 802.3 (Ethernet) li hlalosa ka ho hlaka litekanyo tsa tieho, jitter, le bit error rate bakeng sa ba phetang nakong ea nchafatso ea mats'oao ho netefatsa bots'epehi ba phetiso ea data. Bakeng sa li-fiber optic repeater, maemo a machaba a ITU-T G.957 le G.652 a hlakisa lintlha tse ling tse kang tekanyetso ea matla a mahlo le mamello ea ho hasana ho netefatsa hore -ho khoneha phetiso ea sebaka se selelele.

Khokahano ea Protocol ke karolo e 'ngoe ea mantlha ea litekanyetso tsa ts'ebetsong tse pheta-phetoang. Ka mohlala, ba pheta-phetoang ba Ethernet ba tlameha ho tšehetsa mochine oa CSMA/CD (Carrier Sense Multiple Access/Collision Detection) o boletsoeng ke IEEE 802.3 ho qoba tšubuhlellano ea marang-rang. Li pheta-phetoang tse sebelisoang maemong a liindasteri (joalo ka PROFIBUS kapa liprothokholo tsa Modbus) li tlameha ho ikamahanya le maemo a indasteri{3}}a khethehileng a liprothokholo tsa melaoana ho etsa bonnete ba ho hokahanya ha lilaoli, li-sensor, le lisebelisoa tse ling. Ho feta moo, batho ba pheta-phetoang ka mohala ba tlameha ho ipapisa le maemo a tsoang ho 3GPP (likhokahano tsa mehala) kapa Wi-Fi Alliance (joalo ka IEEE 802.11 series) ho ntlafatsa bokhoni ba ho fetisa melaetsa le ho fokotsa likotsi tsa tšitiso.

Tšireletseho le khokahano ea motlakase (EMC) le tsona li bohlokoa. Meralo e pheta-phetoang e tlameha ho kopana le letoto la EN 61000 la litekanyetso tsa EMC ho fokotsa ho kena-kenana le lisebelisoa tse ling tse bakoang ke mahlaseli a motlakase, 'me e tlameha ho feta liteko tsa taolo tse kang FCC Karolo ea 15 (US) kapa setifikeiti sa CE (Europe). Mabapi le ts'ireletso ea marang-rang, batho ba pheta-phetoang ba tšehetsang IPSec kapa TLS encryption ba tlameha ho lumellana le litlhoko tsa tsamaiso ea ts'ireletso ea tlhahisoleseding ea ISO/IEC 27001 ho thibela ho senya le ho mamela.

Ka kakaretso, litekanyetso tse pheta-phetoang ke motsoako oa ts'ebetso ea tekheniki, litlhoko tsa indasteri le melaoana ea polokeho. Baetsi ba tlameha ho ikamahanya le maemo a machaba le a sebaka ka thata 'me ba fumane lengolo la-litifikeiti tsa mokha oa boraro (joalo ka UL le TÜV) ho netefatsa hore baa li latela, kahoo ba fa basebelisi litharollo tse sebetsang hantle, tse tšepahalang le tse sireletsehileng tsa katoloso ea marang-rang. Nakong e tlang, ka nts'etsopele ea mahlale a kang 5G le Marang-rang a Lintho, maemo a pheta-phetoang a tla tsoela pele ho fetohela ho latency e tlase, bandwidth e phahameng, le likarolo tse bohlale.
