Public Network Walkie-Talkie Performance Analysis: A Double Breakthrough in Connection Efficiency and Reliability

Kankhani-ku-Talk over Cellular (PoC), njira yopititsira patsogolo ya walkie -talkies, imathandizira maukonde olumikizirana a m'manja kuti athe kulumikizana pompopompo, -kumadera osiyanasiyana, kuwonetsa zabwino zake pazamayendedwe, chitetezo, kuchitapo kanthu mwadzidzidzi, ndi zina. Kuchita kwake sikumangotsimikizira zomwe ogwiritsa ntchito akukumana nazo komanso zimakhudza mwachindunji kudalirika kwa kulumikizana muzochitika zovuta. Zotsatirazi zikuwunika machitidwe a public network walkie-zokambirana mosiyanasiyana.

I. Kukula kwa Kulumikizana: "Zopanda Malire" zolumikizira zomwe zimaphwanya malire akutali

Ma walkie -zachikhalidwe amadalira mawailesi a wailesi, ndi njira zoyankhulirana bwino zimangokhala ma kilomita angapo kapena khumi (malinga ndi mphamvu ndi chilengedwe). Ma network walkie-talkies, komabe, amalumikizana ndi ma network kudzera pa 4G/5G kapena Wi-Fi, zomwe zimatheketsa kuti anthu azilankhulana momasuka m'dziko lonselo ngakhale padziko lonse lapansi. Mwachitsanzo, m'matauni okhala ndi masiteshoni owundana, mphamvu za ma siginecha ndi zokwanira kuthandizira kuyimba mokhazikika m'malo oimika magalimoto apansi panthaka komanso m'nyumba zokwera-zokwera. Kumadera akumidzi, malinga ngati pali netiweki (monga 4G signal), public netiweki walkie-talkies imatha kusunga malumikizidwe. Zina zapamwamba-zimagwiranso ntchito ziwiri-SIM dual standby kapena automatic network switching. Chizindikiro choyambirira cha netiweki chikafooka, dongosololi limasinthira mwachangu ku netiweki yosunga zobwezeretsera, ndikuchepetsanso kusokonezeka kwa kulumikizana.

II. Kuthamanga Kwambiri: "Zero Latency" Kukhathamiritsa kuchokera ku Keystroke kupita ku Voice

Phindu lalikulu la walkie{0}}talkies lagona mu "instant messaging." Kuchedwa kwa public network walkie-talkies kumakhudza kwambiri zomwe ogwiritsa ntchito akukumana nazo. Zida zoyambilira zochokera pamanetiweki a 2G/3G nthawi zambiri zinkachedwa 1-3 sekondi imodzi chifukwa chosakwanira bandwidth. Komabe, machipset amakono a 4G LTE Cat.1/Cat.4, kuphatikiza ndi ma protocol otsogola a VoIP, achepetseratu-ku{14}}kutha kuchedwa kufika pa 0.5-masekondi 1.2, tikuyandikira "press and go" ya chikhalidwe cha analogi walkie{18}}talkies's talkies low network{15} yopititsa patsogolo anthu{15} latency (theoretical latency pansi pa 100 milliseconds) kuti akwaniritse zofunikira za zochitika zolondola kwambiri monga kuwongolera kutali kwa mafakitale. Ndizofunikira kudziwa kuti latency yeniyeni imakhudzidwanso ndi kuchuluka kwa maukonde. M'malo odzaza anthu (monga makonsati), ngati masiteshoni adzaza kwambiri, kuchedwa kutha kuwonjezeka kwakanthawi. Komabe, zida zambiri zimawonetsetsa kufalitsa kwachangu kwa mawu kudzera mu QoS (Quality of Service) kukonzekera koyambirira.

III. Ubwino wa Mawu ndi Kumveketsa: Kulinganiza kwa Kukana Kusokoneza ndi Ukadaulo wa Coding

Kamvekedwe ka mawu a public network walkie-talkies amalekeredwa ndi chilengedwe cha netiweki komanso ma code algorithm. Ma analogi achikhalidwe-zolankhula, ngakhale kuti alibe kupsinjika, amatha kusokonezedwa ndi ma elekitiroma, zomwe zimabweretsa phokoso. Anthu olankhula pa netiweki-amalankhula amagwiritsa ntchito makina a digito (monga AMR-mawu a WB wideband ndi Opus adaptive coding) kuti azitha kumveketsa bwino komanso kukana kusokoneza mkati mwa bandwidth yochepa. Zipangizo zamakono zimathandizira 8kHz ndi 16kHz masampling rate. 16kHz wideband coding imatha kutulutsanso zambiri{10}}zambiri (monga kamvekedwe ka mawu komanso kamvekedwe kakumbuyo kozungulira), kuzipangitsa kukhala zoyenera kuchitira zinthu zina zomwe zimafuna kutumiza uthenga wolondola (monga kutsimikizira dongosolo lachitetezo). Kuphatikiza apo, kuphatikiza phokoso-kuletsa maikolofoni ndi njira yolepheretsera echo kumachotsa zosokoneza monga phokoso la mphepo ndi phokoso lamagetsi pazida, kuonetsetsa kuti onse awiri akumva bwino uthenga wofunikira ngakhale pamalo omanga a phokoso kapena m'malo agalimoto.

IV. Moyo wa Battery ndi Kudalirika: Zizindikiro Zofunikira Zanthawi Yaitali-Kagwiritsidwe Ntchito Kanthawi

Nthawi ya batire ya public network walkie-talkies imakhudza kwambiri kuthekera kwawo kogwira ntchito mosalekeza. Zipangizo zanthawi zonse-zimakhala ndi batri yokwana 2000-3000mAh, zomwe zimapatsa maola 8-12 akugwira ntchito mosalekeza pa mtengo wake wonse (kuti agwiritse ntchito{12}}yaching'ono mpaka pang'ono). Mitundu yaukatswiri imagwiritsa ntchito mabatire akuluakulu (4000-6000mAh) kapena imakhala ndi mapangidwe osinthika. Kuwongolera mphamvu mwanzeru (monga kugona ndi kutsika-kugunda kwa batri) kumawonjezera nthawi yogwira ntchito, ndipo mamodelo ena amatha kupitilira maola 15 ogwiritsa ntchito kwambiri. Pankhani yodalirika, mafakitole-ma grade public network intercom housings nthawi zambiri amapangidwa ndi pulasitiki kapena zitsulo zolimba kwambiri, zomwe zimakwanitsa kupeza IP67 (yopanda fumbi ndi yosalowa madzi, yoyenerera kumizidwa kwakanthawi kochepa) kapena IP68 (kuzama kwambiri kukana kulowa pansi pa madzi). Amayesedwanso (kupitirira mamita 1.5) ndikuyesedwa kutentha kwakukulu ndi kutsika (-20 digiri ku 60 digiri), kuonetsetsa kuti ntchito yokhazikika m'madera ovuta kwambiri (monga ntchito zopulumutsa mvula yamkuntho ndi zomangamanga zakunja).

V. Ntchito Yowonjezera: Kuchokera Kuyitana Kwambiri kupita ku Kugwirizana Kwanzeru

Ma intercom amakono apagulu apita kupyola kulankhulana kwa mawu, kuphatikizira zinthu zosiyanasiyana zothandiza kuti ntchito ikhale yabwino. Mwachitsanzo, ma module oyika GPS/Beidou amatha kukweza malo azipangizo kumapulatifomu oyang'anira munthawi yeniyeni, ndikupangitsa malo otumizira kuti aziwunika momwe gulu likutumizidwa. Kutumiza kwa ma multimedia kumathandizira kutumiza zithunzi ndi makanema achidule, kuwapangitsa kukhala abwino kuti{2}}asonkhanitse umboni wapatsamba kapena kupereka ndemanga zokhudzana ndi chipangizocho. Zipangizo zina n'zogwirizananso ndi malumikizidwe a Bluetooth (zomvera m'makutu ndi ma maikofoni am'manja), kutsimikizira kwa NFC (kuti muyang'anire chilolezo), komanso ngakhale mawu a AI-kuti-alembere mawu, kusinthiratu mawu omvera kukhala malekodi kuti azitha kuwona mosavuta. Zowonjezera izi zimawathandiza kuti asamangokwaniritsa zofunikira za intercom komanso kuphatikizira mumayendedwe a digito, kukhala chida chofunikira kwambiri pazanzeru zamakampani.

Chidule cha nkhaniyi: Ubwino wa kagwiridwe ka ntchito ka public network walkie-talkies wakhazikika m'mbali zinayi zazikulu: kufalikira, kutsika kwafupi, kumveka bwino kwa mawu, komanso kudalirika kwambiri. Kuphatikizidwa ndi ubwino wa zomangamanga zamanetiweki a m'manja, amathetsa vuto la ma walkie achikhalidwe-zolankhula, monga kusiyanasiyana komanso magwiridwe antchito ochepa. Ndi kufalikira kwa ma netiweki a 5G komanso kusinthika kwaukadaulo wa chip, public network walkie-talkies ipitilira kusinthika mpaka kutsika pang'ono, kumveka bwino kwambiri, komanso mgwirizano wanzeru, kupereka chithandizo champhamvu chaukadaulo pazosowa zanthawi yomweyo zamafakitale osiyanasiyana.
