WiFi 6 vs WiFi 5: Wireless network routing kuenzanisa

Kufambira mberi kwetekinoroji kunoramba kuripo kwaunza nguva itsva yekubatana kweWiFi 6 isina waya, iyo inotsiva WiFi 5 standard yagara iripo. Sezvo mabhizinesi nevatengi vachigamuchira kukura kweInternet of Things ( IoT) uye kuwedzera kwekuda kwekutumira data nekukurumidza uye kunonoka kwakaderera, kunzwisisa zvinhu zvinosiyanisa zviyero zviviri izvi zvisina waya kunova kwakakosha. Chinyorwa chino chinopa ongororo yakadzama yemusiyano mukuru uripo pakati peWiFi 5 neWiFi 6, zvichipa maonero akazara ekushanduka kwenetwork isina waya.

Gadzirisa yako WiFi PCB dhizaini yeazvino zviyero. Bata nesu nhasi kuti tive nechokwadi chekuvimbika kwechiratidzo uye kuwedzera mashandiro mune yako WiFi 6 kana WiFi 7 zvishandiso.

WiFi 5, yaizivikanwa seIEEE 802.11ac, yaive chizvarwa chechishanu chewireless networking standards, yakaunzwa muna 2014. Kusiyana neizvi, WiFi 6 izita rekutengesa reIEEE 802.11ax standard, iro rakatenderwa muna 2019. Izvi zvekupa zita neWiFi Alliance ine chinangwa chekurerutsa kushambadzira uye kutorwa kweaya matekinoroji.

Network Security Protocols

WiFi 6 yakawedzera zvakanyanya kuchengetedzwa kwetiweki nekutorwa kweiyo yakasimba WPA3 protocol. Nepo WiFi 5 yakatsigira WPA2 chiyero, yaive gadziriso huru pamusoro peyakaitangira WEP, yakanga ichiri nekusagadzikana kwaigona kushandiswa nekurwiswa kwakaoma. WPA3 inotangisa yakagadziridzwa encryption maitiro, akawanda-factor authentication, uye dziviriro kubva muduramazwi-based password yekupwanya kuedza, kusimbisa kuchengetedzeka kwemawaya network.

Dhata Yekutamisa Mitengo

Kudiwa kwekukurumidza kwekufambisa data kwakafambisa kuvandudzwa kweWiFi 6. Kunyange zvazvo WiFi 5 yakanga ine theoretical maximum throughput ye 6.9 Gbps, WiFi 6 inosimudza bar kusvika ku9.6 Gbps inoshamisa. Nekudaro, iyo yechokwadi mukana weWiFi 6 inoonekwa munzvimbo dzakaomarara dzine akawanda akabatana zvishandiso. Leveraging advanced modulation matekiniki (1024-QAM) uye yakagadziridzwa spatial rwizi manejimendi, WiFi 6 inokunda pakuchengetedza yakakwira yekubuda kunyangwe iine akawanda maturusi panguva imwe chete kuwana kunetiweki.

Beamforming uye Spatial Reuse

WiFi 6 inoshandisa yakagadziridzwa nzira yekushongedza mwenje, ichishandisa antenna masere kutarisisa masaini masaini akananga kune anogashirwa. Uku kutapurirana kwakanangana kunovandudza mareti e data uye kunowedzera huwandu hunoshanda hwechiratidzo. Pamusoro pezvo, WiFi 6 inotanga kushandiswazve kwenzvimbo, ichibvumira michina yakawanda kuti ifambise panguva imwe chete pachiteshi chimwe chete pasina kukanganisa, optimize network network uye throughput.

Orthogonal Frequency-Division Multiple Access (OFDMA)

Nepo WiFi 5 yakashandisa Orthogonal Frequency-Division Multiplexing (OFDM) yekutonga netiweki yekuwana, WiFi 6 inotora yakanyanyisa yepamusoro Orthogonal Frequency-Division Multiple Access (OFDMA) maitiro. OFDMA inogovanisa bandwidth inowanikwa kuita madiki zviwanikwa, zvichiita kuti michina yakawanda itumire panguva imwe chete pasina kukwikwidzirana kune mamwe ma subcarriers. Iyi nzira inoderedza zvakanyanya latency uye kusangana, kunyanya mune dense deployment scenarios.

Multi-User, Multiple Input, Multiple Output (MU-MIMO)

MU-MIMO tekinoroji, iyo inogonesa kutaurirana panguva imwe chete pakati pezvishandiso zvakawanda nenzvimbo yekuwana, yakagadziridzwa zvakanyanya muWiFi 6. Nepo WiFi 5 yakatsigira unidirectional 4 × 4 MU-MIMO gadziriso, WiFi 6 inozvirumbidza 8 × 8 bidirectional kuita. Uku kuwedzera kwesimba kunogonesa kuwirirana kwevatengi kwakafanana uye kunonatsiridza hunyanzvi hwekufambisa data, kubatsira maapplication anoda yakakura uplink bandwidth.

Frequency Bands uye Spectrum Utilization

WiFi 5 inoshanda chete mu5 GHz frequency bhendi, ichipa kupindira kushoma asi yakaderedzwa huwandu uye kupinda kana ichienzaniswa ne2.4 GHz bhendi. WiFi 6 inotsigira ese ari maviri 2.4 GHz uye 5 GHz mabhendi, achibvumira zvishandiso kuti zvisarudze zvine simba frequency yenzvimbo yavo. Zvakare, iyo iri kuuya yeWiFi 6E chiyero ichaunza iyo 6 GHz bhendi, ichiwedzera kudzoreredza kuungana uye kugadzira nzira yekukwirira kwepamusoro uye kuderera latency.

Basic Service Set (BSS) Coloring

Chinhu chakasarudzika cheWiFi 6 iBSS coloring, iyo inopa chiziviso chemavara kune yega yega yekutanga seti seti (BSS) mukati metiweki. Iyi meshini inobatsira kudzikisira kupindira uye kupindirana masaini, kusimudzira kuita kwese uye kuvimbika kweiyo isina waya network, kunyanya mune dense deployment scenarios.

Latency Reduction

WiFi 6 inoderedza zvakanyanya latency, inobatsira chaiyo-nguva zvikumbiro uye zviitiko zvinopindirana. Nekusimudzira matekinoroji akadai seOFDMA uye kushandiswazve kwenzvimbo, WiFi 6 inoderedza kunonoka mukufambiswa kwepaketi yedata, kuve nechokwadi chemushandisi akapfava uye anoteera ruzivo rwemitambo, musangano wevhidhiyo, kana zvimwe zvakakosha-zvakakosha maapplication.

Sezvo kudiwa kwewireless bandwidth kuri kuramba kuchikwira, iyo WiFi ecosystem yave kutotarisa kune ramangwana. WiFi 6E, yekuwedzera yeWiFi 6 yakajairwa, inosuma iyo yakamboshandiswa 6 GHz frequency bhendi, ichivhura mikana mitsva yekumusoro-kuburikidza, yakaderera-latency application. Iine mamwe manomwe ekuwedzera 160 MHz chiteshi mu6 GHz bhendi, WiFi 6E inovimbisa kuderedza kuungana uye kugadzira nzira yehunyanzvi huri kusimukira senge chaiyo chaiyo (VR) uye 8K vhidhiyo kutenderera.
