Ts'ebetso ea eona ha e khetholle feela boiphihlelo ba mosebelisi empa hape e ama ka kotloloho ho ts'epahala ha puisano maemong a bohlokoa. Se latelang se sekaseka likarolo tsa mantlha tsa ts'ebetso ea netweke ea sechaba-talkies ho latela maikutlo a fapaneng.

I. Phatlalatso ea Lipuisano: Likhokahano "tse se nang Meeli" tse Felisang Meeli ea Bohole

Lipuisano tsa setso-li sebelisa maqhubu a seea-le-moea-moea, ka mefuta ea puisano e sebetsang e lekanyelitsoe ho lik'hilomithara tse seng kae ho isa ho tse mashome (ho ipapisitsoe le matla le maemo a tikoloho). Li-talkies tsa marang-rang tsa sechaba-leha ho le joalo, li hokahana le likhokahano tsa marang-rang ka 4G/5G kapa Wi-Fi, ka sepheo sa ho lumella likhokahano tse se nang mathata naheng ka bophara esita le lefatšeng ka bophara. Ka mohlala, metseng ea litoropo e nang le liteishene tse teteaneng, matla a mats'oao a lekane ho ts'ehetsa mehala e tsitsitseng libakeng tsa ho paka makoloi ka tlas'a lefatše le ka har'a{7}}meaho e phahameng. Libakeng tse hole, ha feela ho ntse ho ka sebelisoa marang-rang (joalo ka leqhubu la 4G), li-talkies tsa marang-rang tsa sechaba-li ka boloka khokahanyo. Tse ling tsa{12}mefuta tsa maemo a holimo li boetse li ts'ehetsa{13}}SIM dual standby kapa ho switjha netweke ka boiketsetso. Ha lets'oao la mantlha la marang-rang le fokola, sistimi e fetoha kapele ho netweke ea "backup", e fokotsang kotsi ea ho sitisoa ha puisano.

II. Lebelo la Karabelo: "Zero Latency" Ntlafatso ho tloha Keystroke ho ea ho Lentsoe

Boleng ba mantlha ba li-walkie{0}}talkies bo ho "melaetsa hang-hang." The latency ea public network walkie-talkies e ama ka kotloloho boiphihlelo ba basebelisi. Lisebelisoa tsa pele tse thehiloeng ho marang-rang a 2G/3G hangata li bile le tieho ea metsotsoana e 1-3 ka lebaka la marang-rang a sa lekaneng. Leha ho le joalo, li-chipsets tse tloaelehileng tsa 4G LTE Cat.1/Cat.4, hammoho le mekhoa e ntlafetseng ea VoIP, li fokotsehile-ho{14}}ho felisa latency ho isa ho 0.5-metsotsoana e 1.2, ha u ntse u atamela "tobetsa u tsamaee" ka mokhoa oa khale oa analog walkie{18}}talkies'stalkies le li-network tse fokolang{15} tse fanang ka lipuo tse ling tsa marang-rang{15} latency (theory latency tlasa 100 milliseconds) ho fihlela litlhoko tsa maemo a holimo a nepahetseng joalo ka taolo e hole ea indasteri. Ke habohlokoa ho hlokomela hore latency ea sebele e boetse e angoa ke tšubuhlellano ea marang-rang. Libakeng tse nang le batho ba bangata (joaloka likonsarete), haeba liteishene tsa setsi li tletse, ho lieha ho ka eketseha ka nakoana. Leha ho le joalo, lisebelisoa tse ngata li netefatsa phetiso e nepahetseng ea data ea lentsoe ka kemiso ea pele ea QoS (Quality of Service).

III. Boleng ba Lentsoe le ho Hlaka: Ho leka-lekana ha Ho hana Tšitiso le Theknoloji ea Coding

Boleng ba molumo oa public network walkie-talkies e fokotsoa ke maemo a marang-rang le mokhoa oa ho khouta. Li-analog walkie tsa setso-li bua, leha li se na khatello ea maikutlo, li ka ba bonolo ho kena-kenana le makenete ea motlakase, e bakang lerata. Lipuisano tsa marang-rang tsa sechaba-li bua li sebelisa likhoutu tsa dijithale (tse kang AMR-willband ea WB e ngata le Opus adaptive coding) ho leka-lekanya ho hlaka le ho hana litšitiso ka har'a bandwidth e lekanyelitsoeng. Lisebelisoa tsa mantlha li tšehetsa 8kHz le 16kHz reite sa lisampole. 16kHz kHz wideband coding e ka hlahisa lintlha tse ngata tse ntlafetseng{10}}tse kang mantsoe a monate le melumo e sa tsitsang), e leng se etsang hore e tšoanele maemo a hlokang phetisetso ea tlhahisoleseling e nepahetseng (joalo ka netefatso ea taelo ea ts'ireletso). Ho feta moo, ho kenyelletsoa ha lerata{12}}ea ho phumula maekrofounu le algorithm ea ho phumula lerata ho sefa tšitiso e kang lerata la moea le lerata la motlakase, ho netefatsa hore mahlakore ka bobeli a ka utloa melaetsa ea bohlokoa ka ho hlaka esita le libakeng tse lerata tsa kaho kapa tikolohong ea likoloi.

IV. Bophelo ba Betri le Tšepahala: Lisupa-tsela tsa Bohlokwa Bakeng sa-Ts'ebetso ea Nako e Telele

Nako ea betri ea li-walkie-talkies tsa marang-rang e ama ka kotloloho bokhoni ba tsona ba ho sebetsa kamehla. Lisebelisoa tse tloahelehileng-li na le betri ea boholo ba 2000-3000mAh, e fana ka lihora tse 8-tse 12 tsa ts'ebetso ka tefo e felletseng (bakeng sa ts'ebeliso e mahareng ho isa ho e tlase{12}}ka matla). Mefuta ea litsebi e sebelisa libeteri tse khōloanyane (4000-6000mAh) kapa li na le meralo e ka nkeloang sebaka. Taolo ya matla ka bohlale (jwalo ka mokgwa wa ho robala le{15}}battery throttling) e eketsa nako ya tshebetso, mme mefuta e meng e tshehetsa ka dihora tse 15 tsa tshebediso e boima. Mabapi le ho tšepahala, liindasteri{18}}libaka tsa marang-rang tsa sechaba hangata li entsoe ka polasetiki kapa tšepe ea boenjineri ba matla a holimo, tse fihlelang IP67 (e sa keneleng lerōle ebile e sa kenelle metsi, e loketse ho qoelisoa ka nako e khuts'oane) kapa IP68 (ho hana ho qoelisoa ho tebileng). Li boetse li lekoa ho theoha (ho feta 1.5 limithara) 'me li lekoa bakeng sa mocheso o phahameng le o tlaase (-20℃ho 60 degree), ho netefatsa ts'ebetso e tsitsitseng libakeng tse feteletseng (tse kang ts'ebetso ea pholoso ea sefefo le kaho ea ka ntle).

V. Mosebetsi o Atolositsoeng: Ho Tloha ho Bitsa Motheo ho ea ho Tšebelisano e Bohlale

Li-intercom tsa morao-rao tsa marang-rang tsa sechaba li fetetse ka nģ'ane ho puisano e bonolo ea lentsoe, ho kopanya likarolo tse fapaneng tse sebetsang ho ntlafatsa katleho ea mosebetsi. Ka mohlala, li-module tsa GPS / Beidou tsa ho beha maemo li ka kenya libaka tsa lisebelisoa ho li-platform tsa tsamaiso ka nako ea sebele, e leng ho nolofalletsang litsi tsa ho romella ho shebella ho tsamaisoa ha sehlopha. Multimedia e ts'ehetsa ho romella litšoantšo le livideo tse khutšoane, ho li etsa hore e be tse loketseng bakeng sa{2}}ho bokella bopaki ba sebaka kapa ho fana ka maikutlo a boemo ba sesebelisoa. Lisebelisoa tse ling li sebelisana le khokahanyo ea Bluetooth (bakeng sa li-headset le li-microphone), netefatso ea NFC (bakeng sa taolo ea tumello), esita le lentsoe la AI-ho{5}}ho ngola, ho fetolela litaelo tsa lentsoe lirekotong tsa mongolo hore ho be bonolo ho li bala. Likarolo tsena tse atolositsoeng li ba thusa hore ba se ke ba fihlela litlhoko tsa mantlha tsa li-intercom feela empa hape ba kenyelletse lits'ebetsong tsa taolo ea dijithale, ho ba sesebelisoa sa bohlokoa bakeng sa bohlale ba indasteri.

Kakaretso: Melemo ea ts'ebetso ea public network walkie-talkies e tsepamisitsoe ka mahlakoreng a mane a bohlokoa: kakaretso, latency e tlase, boleng ba molumo o matla, le ts'epahalo e phahameng. Ha li kopantsoe le melemo ea lisebelisoa tsa marang-rang tsa mehala, li sebetsana le mathata a tloaelehileng a -talkies, joalo ka mefuta e fokolang le ts'ebetso e fokolang. Ka mokhoa o atileng oa ho amoheloa ha marang-rang a 5G le tsoelo-pele ea theknoloji ea li-chip, li-talkies tsa marang-rang tsa sechaba{5}}li tla tsoela pele ho fetoha ho ea ho latency e tlase, ho hlaka ho hoholo, le tšebelisano e bohlale haholoanyane, ho fana ka tšehetso e matla le ho feta ea tekheniki bakeng sa litlhoko tsa puisano hanghang tsa liindasteri tse fapaneng.
