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

Sundidzira-ku-Talk over Cellular (PoC), imwe nzira yakakwidziridzwa yewalkie-talkies, inoita kuti nharembozha dzikwanise kugonesa kufambiswa kwemashoko chiriporipo, -kumatunhu, kuratidza zvakanakira kufambiswa kwezvinhu, kuchengetedzeka, kugadzirisa dambudziko, nezvimwe. Kuita kwayo hakungotarise ruzivo rwemushandisi chete asi zvakare kunokanganisa zvakananga kuvimbika kwekutaurirana mune dzakakomba mamiriro. Zvinotevera zvinoongorora mabatirwo azvinoitwa eruzhinji netiweki walkie-kutaura kubva mumaonero akawanda.

I. Nhaurirano yeKukurukurirana: "Zvisina Muganho" Zvisungo zvinotyora Miganho yeDistance

Nhau dzechinyakare-dzekutaura dzinotsamira pamasaisai eredhiyo, nekurukurirano dzinoshanda dzinowanzogumira kumakiromita mashoma kusvika kumakumi emakiromita (zvichienderana nesimba nemamiriro ekunze). Public network walkie-talkies, zvisinei, batanidza kunetiweki kuburikidza ne4G/5G kana Wi-Fi, zvichigonesa kugonesa kufambiswa kwemashoko munyika yose uye pasi rose. Semuyenzaniso, munzvimbo dzemudhorobha dzine zviteshi zvepasi, simba remasaini rinokwana kutsigira runhare rwakadzikama munzvimbo dzekupaka dzepasi pevhu uye mukati mezvivakwa zvakakwirira-. Kunzvimbo dziri kure, chero paine network (yakadai sechiratidzo che4G), public network walkie-talkies inogona kuchengetedza kubatanidza. Mamwe mamodhi -akakwirira anotsigirawo maviri-SIM dual standby kana automatic network switching. Kana iyo yekutanga network inopera simba, sisitimu inokurumidza kuchinjika kune backup network, zvichiwedzera kuderedza njodzi yekukanganisa kutaurirana.

II. Kumhanya Kwekupindura: "Zero Latency" Optimization kubva Keystroke kuenda kuIzwi

Iko kukosha kwewalkie{0}talkies kuri mu "instant messaging." Kunonoka kwepublic network walkie-talkies kunobata zvakanangana nemushandisi. Midziyo yepakutanga-tanga yakavakirwa pamanetiweki e2G/3G kazhinji inosangana ne1-3 kunonoka kwesekondi 3 nekuda kwekusakwana kwenetwork bandwidth. Zvakadaro, machipset e4G LTE Cat.1/Cat.4 emazuva ano, akasanganiswa nemaprotocol akakwenenzverwa eVoIP, ane kupera kwakaderera-ku{14}}kupedza latency kusvika 0.5-1.2 seconds, tichisvika pa "press and go" zvechinyakare zveanalogi walkie{18}}talkies yelkies{15} latency (theoretical latency pasi pe100 milliseconds) kusangana nezvinodiwa zvemhando yepamusoro-chaiyo senge maindasitiri kure kure. Izvo zvakakosha kucherechedza kuti chaiyo latency inobatwawo ne network congestion. Munzvimbo dzine vanhu vakawanda (senge makonti), kana zviteshi zvepasi zvakazara, latency inogona kuwedzera kwenguva pfupi. Nekudaro, maturusi mazhinji anovimbisa kufambisa kwenzwi data kuburikidza neQoS (Hunhu hweSevhisi) kuronga kwekutanga.

III. Hunhu Hwezwi uye Kujeka: Iko Kuenzanisa kweKukanganisa Kuramba uye Coding Technology

Maodhiyo emhando yepublic network walkie-talkies inoganhurirwa nenetiweki nharaunda uye coding algorithm. Matauriro echinyakare eanalogi-asina kukanganiswa, anogona kukanganiswa nemagetsi, zvichikonzera ruzha. Public network walkie-talkies inoshandisa digital coding (se AMR-WB wideband voice uye Opus adaptive coding) kuenzanisa kujeka uye kukanganisa kurambwa mukati mebandwidth shoma. Midziyo yeMainstream inotsigira 8kHz uye 16kHz sampling rates. 16kHz wideband coding inogona kuburitsa yakakwira zvakanyanya-frequency details (zvakadai semanzwi anonzwika uye manzwi akapoteredza), zvichiita kuti zvienderane nemamiriro anoda kufambiswa kwemashoko chaiwo (sekuongororwa kwekuchengetedzwa). Pamusoro pezvo, kusanganisirwa kweruzha{12}}kukanzura maikorofoni uye echo kukanzura algorithm zvinosefa kunze kuvhiringika kwakadai seruzha rwemhepo uye ruzha rwemagetsi emidziyo, kuita kuti mapato ese ari maviri anzwe zvakajeka mameseji akakosha kunyangwe munzvimbo dzine ruzha dzekuvaka kana nzvimbo dzemotokari.

IV. Upenyu Hwebhatiri uye Kuvimbika: Zviratidzo Zvinokosha Zvenguva Yakareba-Mashandiro Enguva

Nguva yebhatiri yeruzhinji netiweki-talkies inokanganisa kugona kwavo kushanda nguva dzose. Zvishandiso zvemutengi zvakajairika-zvinowanzoita bhatiri rinokwana 2000-3000mAh, zvinopa 8-maawa 12 ekushanda nguva dzose pachaji yakazara (pakushandisa zviri pakati nepakati kusvika pasi{12}}zvakanyanya). Mhando dzehunyanzvi dzinoshandisa mabhatiri akakura (4000-6000mAh) kana ane madhizaini anotsiviwa. Hungwaru kutonga magetsi (sekurara uye kushomeka-bhatiri throttling) inowedzera nguva yekushandisa, nemamwe mamodhi achitotsigira kwemaawa gumi nemashanu ekushandisa zvakanyanya. Panyaya yekuvimbika, maindasitiri-giredhi republic network intercom housings anowanzo gadzirwa nepurasitiki kana simbi yeinjiniya yakasimba, achiwana IP67 (isina guruva uye isingapindi mvura, inokodzera kunyudzwa kwenguva pfupi) kana IP68 (yakadzika kunyura mumvura). Ivo zvakare vanodonha-kuedzwa (kupfuura 1.5 metres) uye vakaedzwa kune yakakwirira uye yakaderera tembiricha (-20 dhigirii kusvika 60 dhigirii), kuve nechokwadi chekushanda kwakadzikama munzvimbo dzakanyanyisa (zvakadai semabasa ekununura mvura uye kuvaka kunze).

V. Basa Rakatambanudzwa: Kubva Kufona Kwekutanga kuenda kuKushanda Kwenjere

Mazuvano veruzhinji network intercoms apfuura kupfuura nyore kutaura kwezwi, kubatanidza zvakasiyana-siyana zvinoshanda kusimudzira kushanda zvakanaka. Semuyenzaniso, GPS/Beidou positioning modules inogona kurodha nzvimbo dzemudziyo kumapuratifomu ekutonga munguva chaiyo, zvichiita kuti nzvimbo dzekutumira dzitarise kutumirwa kwechikwata. Multimedia transmission inotsigira kutumira mifananidzo nemavhidhiyo mapfupi, zvichiita kuti zvive zvakanakira -kuunganidza humbowo hwesaiti kana kupa mhinduro yemamiriro emudziyo. Mimwe midziyo inoshandawo neBluetooth yekubatanidza (yemahedhifoni uye mamaikorofoni anobatwa paruoko), chokwadi cheNFC (yekune mvumo), uye kunyange AI voice-ku-mameseji, inoshandura otomatiki mirairo yezwi kuita zvinyorwa kuti zvionekwe zviri nyore. Aya maficha akawedzerwa anovagonesa kuti vasangosangana nezvinodiwa zveintercom chete asi kuti vabatanidze mumadhijitari manejimendi maitiro, kuita chishandiso chakakosha chehungwaru hweindasitiri.

Pfupiso: Zvakanakira kuita zveruzhinji netiweki walkie-talkies zvakanangana mumativi mana akakosha: kuvharika, kudzika pasi, kusimba kwekunzwika, uye kuvimbika kwepamusoro. Zvichisanganiswa nezvakanakira zvenharembozha network, vanogadzirisa zvinorwadza zvechinyakare-kutaura, senge nhanho shoma uye mashandiro mashoma. Nekutorwa kwakapararira kwe5G network uye shanduko yechip tekinoroji, public network walkie-talkies icharamba ichishanduka ichienda kwakadzikira latency, kujeka kwepamusoro, nekubatana kwakangwara, zvichipa tsigiro yakasimba yehunyanzvi yezvinodiwa zvekutaurirana nekukurumidza kwemaindasitiri akasiyana.
