Generic access network definition
A generic access network (GAN) is a system that makes it possible for your mobile device to connect to the internet or make calls using different types of networks. For example, if you’re at home or in a library, it uses Wi-Fi. When you’re on the move, it switches to cellular networks. GAN ensures you’re always connected — and can even save you money by picking the best network.
How generic access network works
- GAN starts by checking what networks are available around your smartphone.
- It chooses the best network based on how fast it is, how much it costs, and signal strength. For example, if Wi-Fi is strong and affordable, it connects through Wi-Fi.
- As you move around, GAN continuously checks which network is best and smoothly switches between them. So, if you can no longer reach the Wi-Fi you were connected to, it seamlessly shifts to cellular without interrupting your calls or browsing.
Generic access network benefits
- GAN can save you money by using Wi-Fi when it’s available, which is often cheaper than cellular data.
- It improves coverage because you can use any accessible network, so you’re not limited to just one type.
- GAN ensures good call quality and internet speed, even when switching between networks.
