Wi-Fi calling allows users to make phone calls over a Wi-Fi network, prioritizing speech over data in real-time voice environments. This technology is supported by both phones and carrier networks, and requires either a single mode phone in a Wi-Fi hotspot or a dual-mode phone that can switch between cellular and Wi-Fi hotspots. Wi-Fi calling was created to improve call quality in areas with poor cellular connection and can also save users money on plans with limited monthly minutes. Additional names for this technology include voice over Wi-Fi, Wi-Fi telephony, wireless VoIP, and voice over wireless LAN.
What is Wi-Fi Calling?
Using a Wi-Fi network to make phone calls is called Wi-Fi calling. This technology is used to prevent dropped calls in areas with poor cellular connection. It is supported by both the phones and the carrier network, giving speech priority over data in the real-time voice environment. This means that users can only place calls using a single mode phone inside of a Wi-Fi hotspot. However, dual-mode phones can smoothly switch between the cellular carrier and open or pre-qualified Wi-Fi hotspots.
Benefits of Wi-Fi Calling
Wi-Fi calling provides many benefits to users, especially those with carrier plans that include a set number of monthly minutes. Here are a few advantages of using Wi-Fi calling:
No additional charges: Wi-Fi calling doesn’t require any extra charges or fees. It is a free service provided by cellular carriers.
Better call quality: Because Wi-Fi calling gives speech priority over data, it provides better call quality than cellular network calls. Wi-Fi networks are usually faster and more reliable, which results in improved voice quality.
Extended coverage: Wi-Fi calling can help you make calls in areas where cellular signals are poor or nonexistent. It works as long as there is a Wi-Fi hotspot available.
Lowered roaming charges: Wi-Fi calling can save you money on roaming charges when you’re traveling abroad. Instead of making expensive International calls, you can use Wi-Fi to make calls for free or at a lower cost.
How Does Wi-Fi Calling Work?
Wi-Fi calling works by using a Wi-Fi network to transmit voice data instead of a cellular network. It uses the internet connection to establish a connection between two phones or users. When a user places a Wi-Fi call, the phone sends the call over the internet to the carrier’s servers, which route it to the recipient’s phone or carrier network. The recipient doesn’t need to have Wi-Fi calling enabled to receive the call.
Wi-Fi calling requires specific software and configuration settings, which can vary by carrier and phone model. Therefore, it’s essential to check if your phone and carrier support Wi-Fi calling before attempting to use it.
Wi-Fi calling is a beneficial technology that can help you make calls in areas with poor cellular connection. It’s supported by both the phones and carrier networks, making it a reliable way to communicate. With Wi-Fi calling, you can enjoy better call quality, extended coverage, and lower costs. As long as you have a Wi-Fi hotspot available, you can make calls without worrying about dropped connections or high fees.
