A WiFi hotspot is an access point that provides Internet connection to other devices.

There are hotspots or Internet access points both fixed and mobile, 5G, public,…

It’s something that many users will even do on a daily basis, by Offering Internet access via WiFi and the smartphone’s own data connection. to other devices such as tablets, laptops, portable consoles, ebook readers…

But that wireless connection with can be established with different types of hotspots, since these access points can be both fixed and mobile, beyond that the cell phone itself can come to function as one of them.

In any case the hotspot offers WiFi coverage but the hotspot must be provided with Internet access. This may be via an Ethernet cable that connects it to the router of the fixed installation or with a SIM card that allows it to access the wireless signal of a fixed telephone operator.

-Fixed hotspot: They offer higher signal strength, greater coverage, allow access to a larger number of devices and can offer all of them bandwidth savings. They are permanently installed and connected via Ethernet network to a router and are powered from the mains also via cable, without a battery.

-Mobile hotspot: They are small devices, smaller than a smartphone, equipped with their own connection, their own rechargeable battery and their own SIM card tray. After placing and configuring the SIM card (which needs its own mobile data line) it will offer WiFi coverage to the devices around it exactly as if it were a wireless WiFi router. All of them usually offer 4G connectivity but there are already starting to be a variety of devices with 5G. They can be very useful on trips where you do not want to depend on finding public WiFi networks or at small events where you prefer to have control over the mobile connection offered to small groups of users.

-Hotspot 5G: They can be both fixed and mobile and the difference with those already mentioned is that 5G coverage is added.

-Public hotspot: Museums, stations, airports… various organizations and public spaces can offer a free Internet access service. Connectivity is usually limited in terms of speed or bandwidth, and except in cases of necessity it is not advisable to rely on this type of public access and it is recommended to equip the device with security measures (firewall, VPN, navigation, etc.).

-The mobile hotspot: It is the one that is more accessible since it is incorporated in most of the latest generation smartphones and can be activated from the wireless connectivity settings. Using 3G/4G/5G connectivity, the cell phone connects to your data plan and via WiFi becomes an access point to which other devices can connect to access the Internet.

Some operators limit this capability and mobile manufacturers and operating system developers themselves may also set limits on the number of devices that can access the WiFi network generated by the mobile hotspot, usually ranging between 10 and 15 devices. The configuration that allows sharing the mobile connection also allows a password to be set to restrict who can access this shared WiFi network.
