How Does Wi-Fi Work?
Wi-Fi design is fundamentally built nowadays in homes and workplaces. However, it is crucial to understand what Wi-Fi is and how it works before designing one. Different names, such as wireless LAN or WLAN, can describe Wi-Fi or Wireless Fidelity.
ESP32 is one of the main modules used to implement WI-FI systems with open-source platform.
Wi-Fi was invented in the late 90s. However, many users still mistake it for the Internet. Yes, Wi-Fi provides access to the Internet, but it’s not exactly the Internet.
Since Wi-Fi is a wireless technology, it uses radio waves to transmit data in a limited geographical area. In all devices with wireless design, communication is a bidirectional sending and receiving of radio signals.
The integrated networking module in your device translates the signals (data) into radio waves and transmits them via an antenna. In early machines, the antennas were externally visible; however, nowadays, they are enclosed inside the devices.
A wireless router or modem catches the signals and decodes them. It transmits the signals to the Internet via Ethernet cables.
The exact process happens in reverse order as well. When you request information from the Internet (a simple Google search), the required information flows through the connected Internet cable to the router. The incorporated modules convert the data into radio waves transmitted via the router’s antennas. Your device receives the signals, decodes them, and resultantly you see your request’s results on the screen.
Most users use the words routers and modems interchangeably. However, the terms need to be clarified when you make a Wi-Fi design. It is important to note that both devices (modems and routers) are suitable for setting up Wi-Fi.
Since modulation/demodulation and routing are necessary. Nowadays, wireless routers incorporate both characteristics.
Wireless communication can not occur without radio signals, so standalone modems must be radio. A better approach is to use router-modem combo devices because they allow you to use multiple devices on a signal Wi-Fi source and offer more security. In contrast, if you use a modem, you’ll only be able to connect a limited number of devices.
Another critical concept in Wi-Fi design is the standards. A standard is an agreement the communicating devices must satisfy to communicate efficiently. For instance, a phone or PC compatible with Standard A will only connect a modem/router working on the same standard (i.e., Standard A).
IEEE defines the Wi-Fi standards under 802 networking standards, but several sub-standards exist.
802.11b: It is the most primitive network standard introduced in 1999, which transmitted 2.4GHz radio spectrum. The per-second data transmission rate was 11 Mbps.
802.11a: 802.11a was released sometime after 802.11b in 1999, and both standards were publicly available for Wi-Fi designs in the same year. The range for these transmission standards was 5GHz, and the per-second raw data rate increased to 54Mbps.
802.11n: The standard was introduced in 2009. However, the devices supporting this standard are backward compatible with 802.11a/b/g. The 802.11n or Wi-Fi 4 works with multiple antennas.
It implements the concept of MIMO (Multiple Input and Multiple Output), so you can connect various sending and receiving devices on a single end of the communication link. It can transmit 54 Mbps (theoretically).
Practically, it transmits only 24Mbps. It supports four streams of data, each one capable of transferring 150 Mbps.
802.11ac: It is the succeeding standard of 802.11n, which appeared in 2014 and has a transmission frequency of 5GHz. Unlike its predecessors, this standard Wi-Fi 5 is less vulnerable to interference and has a per second transmission speed of 450Mbps.
Similar to its predecessor, the 802.11n, 802.11ac can transmit up to 8 streams of data. The combined data transfer speed of the streams exceeds one Gigabit; therefore, it is sometimes also known as Gigabit Wi-Fi.
802.11 ax: The standard that appeared in the digital industry in 2019. It is superior to 802.11ac as it has a transmission rate of 9.2Gbps. Sometimes referred to as Wi-Fi 6, it allows devices to maintain multiple antennas on the same machine. Moreover, it is less vulnerable to bandwidth congestion.
The future standard called 802.11be, which will be implemented by 2024, is 802.11be or Wi-Fi 7.
Why Do We Need Wi-Fi in Our Products?
In many applications, we need a bridge of connectivity to access the Internet and cloud services. Wi-Fi is the most cost-effective way.
Connected devices are easy to troubleshoot. For instance, if your refrigerator stops working, it is challenging to pinpoint which part needs repairing. Instead, if you have a Wi-Fi-enabled appliance, a testing signal quickly finds the defective part. Modern-day Wi-Fi designs mostly use 802.11 ac, so it is best to check the device’s compatibility before purchase.
Remote monitoring allows you to control your devices or gadgets from your mobile. Wi-Fi-enabled printers are a typical example. You can send print commands from your phone to your printer regardless of the distance as long as both devices have access to Wi-Fi.
Device-to-device communication is also a feature that allows you to control other devices from one device. For example, you can manage your washing machine from your TV.
Some Applications of Wi-Fi
We are speedily moving towards an age where Internet access will be inevitable. According to various studies, Wi-Fi will be the most used source of connectivity. Therefore, many companies will specialize in Wi-Fi design. Some typical applications are presented below.
Wi-Fi is required for home automation, like setting up your coffee maker at a specific time to prepare your coffee before you wake up. Wi-Fi will help offload the traffic from the mobile base stations as many people will prefer using Wi-Fi when it is available (the reason being fastness).
Arshon uses ESP32 as a module to implement WI-FI systems and can develop very complex communication of this WI-Fi platform.
Wi-Fi can also help implement the most uprising phenomenon called IoT. The connected devices adjust according to the information received and then function to deliver optimal services.
Furthermore, Wi-Fi is mainly present in organizations and industries as it allows VoIP and video conferencing facilities. Inventories also use Wi-Fi to update and modify real-time stock statuses in their databases.
