The first wireless networking standard was $802\mathrm{.}11.$ Released in $1997.$ It's outdated. While $802\mathrm{.}11$ devices usually cooperate, interference can arise. Because so many devices employ the most popular wireless networking technologies $(802\mathrm{.}11$b$,802\mathrm{.}11$g$/$n$,$ and $802\mathrm{.}11$n$),$ I think they are most susceptible to interference. The fastest Wi$-$Fi is $802\mathrm{.}11$ac$,$ or $5$G$.$ Standard Wi$-$Fi speeds reach $2167$ Mbps$.$ Speed is crucial to network performance, but range signal strength and obstacle difficulties are also vital. Each standard has distinct equipment prices. Everything concerning cost depends on standard capabilities. For instance, $802\mathrm{.}11$ costs more than $802\mathrm{.}11$b due to its longer signal range. Even though $802\mathrm{.}11$ac is more expensive than prior wireless networking technologies, I recommend it$.$ It is the fastest wireless networking technology and least prone to interference since it allows several simultaneous connections.
