It is not necessary to use a wired connection to connect to the Internet – there are many other options. Mobile hotspot (modem mode) is an interesting way to distribute the Internet from your smartphone.
The functionality is built into iOS and Android and is easy and convenient to use. When giving out, the user uses his phone to connect other gadgets to the Internet. How to do this safely, what is the difference between a mobile hotspot and wireless Wi-Fi connection via a router, we will find out below.
Wireless and mobile communications
First, let’s understand what a Wi-Fi hotspot in your phone is. Wireless and mobile Internet are different concepts. To connect to a wireless network, you use a router, a network equipment responsible for connecting a number of devices to the Internet. It distributes IP addresses for laptops, tablets, phones and distributes the network among them.
A router is not the same as an access point, although in many ways they are similar. Smartphone access is a stripped-down, simplified version of a router. It doesn’t create a network like a router, but connects devices to an existing network.
The access point in your phone doesn’t give out IP, it doesn’t connect to your ISP, and it doesn’t have a built-in firewall. It itself connects to the router, and then distributes the Internet via Wi-Fi.
A smartphone that supports modern communication standards can be used to distribute the Internet. Do not confuse the phone and the router – these are different devices and systems, although they are used for the same purpose.
The procedure for setting up an access point, taking into account the type of operating system is described in this overview. All smartphones support the function. Be sure to set a password to protect the network, limit distribution access to a certain set of devices (all these parameters can be specified in the settings of your smartphone).
