<p dir="ltr" style="text-align:justify">It receives the signal with a small antenna in the wireless signal range and converts it back into binary code for the PC to read. This process also works in reverse. </p>

<p dir="ltr" style="text-align:justify">The card converts information from the PC into radio waves and sends it to the router. They are binarized at the router and transmitted to the Internet.</p>

<p dir="ltr" style="text-align:justify">Wifi cards work under the 802.11 standard variants. 802.11b and 802.11g  are the most widely used standards. The latest 802.11n standards are less widely used.</p>

<p dir="ltr" style="text-align:justify">Wireless internet cards are designed to operate at higher frequencies to process more data (typically 2.4 GHz or 5 GHz). 5 GHz Wifi cards based on 802.11 ac are compatible with wave 2 wifi. </p>

<p dir="ltr" style="text-align:justify">What is wave 2 wifi? It is the second wave of wireless network clients built with 802.11 ac standards. If you set up a wave 2 wifi, your network speed is faster than wave 1. You can run a   to double-check the final result. </p>
