What is a WiFi hotspot and how does it work?
A WiFi hotspot is an Internet access point that uses a wireless network to connect different devices to the network.Although the term may sound technical, its operation is very similar to that of a home router: the hotspot acts as a gateway between devices and the internet, allowing data transmission without the need for cables.
Today, hotspots are present in a wide variety of locations: from coffee shops, bookstores, train stations, and airports to hotels, shopping malls, parks, and public buildings. Many city councils even offer free internet access through public networks to promote citizen connectivity.
A hotspot can be a dedicated device (such as a portable router) or a feature included in mobile phones and other devices.The goal is simple: create a Wi-Fi network that multiple users can connect to simultaneously, allowing internet access without consuming their own mobile data, or taking advantage of shared rates.
A hotspot's coverage depends on factors such as the device's power, the type of antenna used, and interference from other devices. In open spaces, the signal can reach tens or even hundreds of meters, while indoors it may be limited by walls or metal structures.

Types of WiFi hotspots: public, private, mobile, and more
know the different types of hotspot It is essential to identify which one best suits each need:
Public Wi-Fi hotspots
Public WiFi hotspots are the most widespread, present in libraries, cafes, universities, plazas, airports, shopping malls, and government buildings. These are generally networks free or with limited access via password, although in some cases they may require payment for use or prior registration.
Many governments, local governments, and internet service providers promote these hotspots to facilitate digital inclusion. Sometimes, use is free for a limited period, and if the time limit is exceeded, an additional fee is charged.
Private WiFi Hotspots
Mobile WiFi Hotspots
This mode. When you activate the mobile hotspot feature, your device shares its data connection through its own Wi-Fi network, allowing other devices to connect and browse using that data plan.
It's ideal for situations where there's no traditional Wi-Fi coverage, such as traveling, outdoor meetings, or home emergencies. Keep in mind that intensive use can quickly drain your data plan or battery.
Prepaid or paid WiFi hotspots
Rates typically vary depending on the amount of data or connection time purchased, and once the balance is used up, the package must be renewed to continue browsing. This is a flexible option for those who need occasional and secure internet access outside their usual network.
Dedicated portable hotspots
Their compact size and battery life make them perfect for travelers, students, or professionals who need to be connected anytime, anywhere. They can be purchased at electronics stores or through mobile operators, and generally allow you to customize the network name and password.
Differences between hotspot, tethering, and internet sharing
- hotspot: Refers to the physical or virtual point that distributes the WiFi signal for Internet access.
- tethering: It is the function that allows a device (usually a mobile phone) to share its data connection with others, either via WiFi (creating a hotspot), USB or Bluetooth.
- Share internet: Common expression to refer to the above options, but can cover both wired and wireless methods.
In practice, creating a mobile hotspot involves using Wi-Fi tethering, while Internet sharing also includes connecting via USB or Bluetooth.
Is it safe to use a hotspot? Security risks and best practices
Using a public or shared hotspot is never without risk., especially when the network is open or lacks advanced protections. The main dangers include the possibility of a cybercriminal intercepting communications (Man in the Middle attacks), network spoofing attempts (fake Wi-Fi networks), or theft of passwords, banking details, and other confidential information.
Among the most relevant security risks are:
- data interception: Data sent and received over an insecure network can be captured by unauthorized third parties.
- Man-in-the-middle attacks: The attacker positions himself between the user and the target server, intercepting or altering the communication.
- Fake networks or malicious twins: They copy the name of a legitimate network to trick users into accessing their credentials.
- Access to vulnerable devices: Some computers with low security settings can be attacked directly from the same network.
Measures for safe browsing on public and private Wi-Fi hotspots:
- Always use a VPN (Virtual Private Network) to encrypt data and protect privacy while browsing.
- Check the network name with the establishment manager to avoid connecting to fake networks.
- Keep your operating system and antivirus updated to reduce vulnerabilities.
- Avoid accessing sensitive information or perform banking transactions on public networks, especially if they are not encrypted (without an HTTPS lock).
- Disable automatic connection to WiFi networks on the device to avoid unwanted links.
- Turn on the firewall on your laptop or device to block unwanted connections.
- Check that websites use HTTPS before entering passwords or personal data.
- Sign out and delete the network after using a public hotspot for added security
Following these recommendations can make using hotspots much safer, although it's always best to use them only for non-sensitive activities such as reading the news, checking public information, or chatting.
Setting up and using a mobile hotspot: step by step
Turning your phone into a Wi-Fi hotspot is a feature offered by most modern devices, both Android and iOS. This allows you to share your data connection with other devices (laptops, tablets, smart TVs, etc.) in a simple and flexible way.
