How Wifi Modem Works

What Is Wifi Modem And Router: How Wifi Modem Works

Nowadays, wifi modem and router play a crucial role in our day to day life. They are the first thing we set up when we move into a new place, yet many of us don’t know how wifi modem works.

We will discuss modulation, demodulation, and signal interference in connection with wifi modem and how they work together to provide seamless internet connectivity.

Modulation

Modulation is the process when the information is added to an electromagnetic wave carrier signal, making it easier to transmit over long distances. Wifi modems use a technique known as orthogonal frequency division multiplexing (ofdm) to transmit data wirelessly to devices.

Ofdm splits the signal into multiple smaller sub-signals, which can travel through the air easily. By using this signal-modulating technique, wifi modems can transmit more data faster and more efficiently.

Modems can also use different modulation techniques such as qam (quadrature amplitude modulation) and psk (phase-shift keying) to encode digital signals into analog waves for smooth transmission and reception of wireless signals.

Demodulation

Demodulation is the process when the encoded information gets extracted from the carrier signal, which is then decoded by the modem. The modem then reconstructs the original data by piecing together those different small sub-signals. It then sends a signal to the router, which in turn sends the signal to the connected devices.

This process occurs so that we can browse the internet and perform different online activities at high speeds.

Signal Interference

Signal interference is the biggest challenge to a wifi modem’s performance. Different obstructions between the modem and device may cause signal interference, which can lead to poor signal strength and slow internet speeds. Let’s discuss some sources of interference:

• Physical barriers like walls or furniture between the devices and the wifi modem
• Other electronic devices using similar frequencies that interfere with the wireless signal such as cordless phones, microwaves, and bluetooth devices
• Radio frequency interference from other routers in the neighboring buildings operating on the same channel

To minimize the impact of interference, wifi routers use frequency agility- by hopping between various frequency ranges and channels and choosing the least crowded, to ensure the fastest and most stable connection.

Wifi modems use modulation and demodulation techniques to transmit signals to connected devices and provide seamless internet connectivity. Signal interference, however, remains a constant challenge, yet the technology behind the wifi modem and routers’ frequency agility helps overcome such challenges.
