The data subscription plan provided by the Internet Service Provider is not the only option for accessing the internet today. Our smartphone offers many other ways to share and access the internet.
We can share our internet connection with nearby devices using wifi and Bluetooth hotspots. Although wifi hotspot is a commonly used term, there are significant differences between wifi and hotspot.
Key Takeaways
- Wi-Fi is a wireless networking technology that enables devices to connect to the internet or communicate with one another without physical cables, using radio frequencies.
- A hotspot is a physical location or device that provides internet access to Wi-Fi-enabled devices, such as smartphones, laptops, and tablets, through a wireless local area network (WLAN).
- While Wi-Fi refers to the technology itself, a hotspot is a specific application of Wi-Fi technology allowing multiple devices to access the internet through a single connection point.
WiFi vs Hotspot
Wi-Fi is a wireless networking technology that allows devices to connect to the internet or a local area network wirelessly, using a router or access point. A hotspot is a specific location where a wireless network is created by a device, such as a smartphone or a dedicated hotspot device.
Wifi stands for wireless fidelity. It is a set of protocols to access the internet without wires.
Its range is limited to a local area network (LAN).
A hotspot is a physical location that identifies a local area network. It creates many wireless access points for the users.
These points can then be accessed using the wifi or Bluetooth of a network device.

What is WiFi?
Wifi stands for wireless fidelity. It is based on the IEEE 802 protocol family.
It provides clients in a Local Area Network with internet access.
Almost all devices nowadays are equipped with wifi support. We can access wifi on our smartphones, laptops, tablets, and computers.
The wifi technology uses a 2.4 GHz Ultra-High Frequency radio band. Due to obstructions such as walls and doors, the range of wifi is affected.
We can set up a wifi hotspot by allowing our smartphone to share its internet. On a small scale, this includes connecting one or two devices to our phones with password protection.
Today, wifi provides data transfer speeds up to 1 Gbit/s. Since it is more vulnerable to being hacked, it is protected using Wi-Fi Protected Access.
Wifi has an extra advantage over wired Ethernet. It can be used in places where cables cannot be laid down.
Wired Equivalent Privacy (WEP) was initially designed to protect wifi networks. However, its vulnerability led to the Wi-Fi Protected Access (WPA) design.
Also, Virtual Private Networks (VPNs) effectively keep the data safe in a public wifi network.
What is Hotspot?
A hotspot is a physical location characterized by a network device that provides internet access to clients. A hotspot may be wireless or wired.
It uses wifi as the protocol and routers as network devices to provide internet access to devices in a Wireless Local Area Network. However, wifi is not the only option.
Bluetooth and USB cables can also be used to share the internet connection. In this case, the device is said to tether.
There are two types of hotspots based on the traffic of clients. These are public hotspots and private hotspots.
Public hotspots are created using Wireless Access Points (WAPs) and routers. They are set up by hotels, libraries, and other organizations to provide services to visitors.
A private hotspot is also called tethering. It is used to share the internet subscription of a smartphone with other nearby devices.
Tethering can be realized using Bluetooth sharing or a USB connection.
There are several security concerns associated with the hotspot. The wifi connection must be encrypted so that the hackers may not steal valuable data.
Also, the hotspot provider has access to the contents searched by the clients.
However, the popularity of hotspot access is quickly increasing among people. From 2012 to 2018, the hotspots worldwide have increased from 5.2m to 10.5m.
Main Differences Between WiFi and Hotspot
Wifi and hotspot aren’t the same. Wifi is a wireless method of connection to internet service providers. Hotspot is a setup that provides internet access.
Wifi is mainly used to set up a hotspot, although other technologies exist.
The main differences between the two are :
- Wifi stands for wireless fidelity and is a Local Area Network connection method. On the other hand, a hotspot is a device or location that provides internet access to single or multiple clients on a Local Area Network.
- Wifi is a set of protocols, whereas the hotspot is a physical location.
- Wifi is provided by the Internet Service Provider, whereas different corporations set up hotspots.
- Wifi is more secure as denying access to suspicious clients is easy. On the other hand, a hotspot is less secure as anyone within the range can access it.
- The higher cost is associated with accessing wifi from an ISP, whereas public hotspots are free.
