Wi-Fi and its limitations: Interference and problems in broadcasting and video streaming

Wi-Fi has become an integral part of our lives, allowing us to connect to the internet wirelessly and enjoy a wide range of online services. However, despite its convenience, Wi-Fi also has certain limitations that can significantly affect the quality of live broadcasts and video streaming. In this article, we will explore the common issues associated with Wi-Fi, the interference that can arise, and why this technology may not be the ideal choice for real-time broadcasts and high-quality video streaming.

Common Wi-Fi problems

  • Interference: One of the biggest challenges with Wi-Fi is interference. Other electronic devices, such as cordless phones, microwaves, and even neighboring Wi-Fi networks, can operate on the same frequency as your network, which can cause interruptions and degrade the signal.
  • Limited range: The Wi-Fi signal has a limited range and can be weakened by obstacles such as walls and ceilings. This can result in a slow or unstable connection, especially in areas far from the router.
  • Shared bandwidth: On a Wi-Fi network, all connected devices share the same bandwidth. If multiple devices are transmitting or downloading data simultaneously, the connection speed can decrease for all users.
  • Latency: Latency refers to the time it takes for a data packet to travel from the device to the server and back. On Wi-Fi networks, latency can be higher than on wired connections, which can affect the quality of video calls and online games.

Interference in Wi-Fi

Interference can be caused by a variety of sources, including:

  • Other electronic devices: Devices such as cordless phones, microwaves, baby monitors, and some Bluetooth devices can operate on the same frequency as Wi-Fi, which can cause interference.
  • Neighboring Wi-Fi networks: If you live in an apartment building or a densely populated area, there are likely many Wi-Fi networks around you. These networks can interfere with each other, especially if they are set up on the same channels.
  • Physical objects: Thick walls, ceilings, and metal furniture can block or weaken the Wi-Fi signal, which can increase the likelihood of interference.

Wi-Fi and broadcasting/video streaming

Live broadcasts and video streaming require a stable, high-speed internet connection with low latency. Unfortunately, due to its inherent limitations, Wi-Fi may not be able to consistently meet these requirements.

  • Interruptions and buffering: Interference and bandwidth fluctuations can cause interruptions in the transmission and frequent buffering, which can ruin the viewing experience.
  • Reduced video quality: To compensate for an unstable connection, streaming services may automatically reduce the video quality, resulting in a pixelated or blurry image.
  • Transmission delay: Latency on Wi-Fi networks can cause a noticeable delay in live streaming, which can be problematic for real-time events such as sports or concerts.

Alternatives to Wi-Fi for broadcasts and streaming

If you plan to do live broadcasts or high-quality video streaming, consider these alternatives to Wi-Fi:

  • Wired Ethernet connection: A wired Ethernet connection offers a much more stable and faster internet connection with lower latency than Wi-Fi. If possible, connect your device directly to the router using an Ethernet cable.
  • 5G mobile networks: 5G networks offer significantly faster connection speeds and lower latency than previous 4G networks. If you have a 5G data plan and good coverage in your area, this can be a viable option for live broadcasts and streaming.

Conclusion

While Wi-Fi is a convenient technology for wireless internet access, its limitations can affect the quality of live broadcasts and video streaming. Interference, limited range, and shared bandwidth can cause interruptions, buffering, and reduced video quality. If quality and stability are crucial for your broadcasts, consider using a wired Ethernet connection or a 5G mobile network as an alternative to Wi-Fi.
