Ever since the first Wi-Fi standard came out in 1997, Wi-Fi technologies have evolved allowing more people and wireless devices to access the internet and stay connected seamlessly.
As much as Wi-Fi hotspots are fast, easily accessible, and convenient, they have their limitations.
Most of the current Wi-Fi technologies do not support roaming, meaning you have to select a new network and log in your credentials afresh when moving from one Wi-Fi hotspot to the next, taking much of your time.
Fortunately, Wi-Fi hotspot 2.0 is here to change this scenario by addressing these specific issues and other Wi-Fi challenges.
This post explains everything you need to know about the game-changing Wi-Fi Hotspot 2.0.
What Exactly is a Wi-Fi Hotspot 2.0?
Wi-Fi Hotspot 2.0 is an interoperable Wi-Fi standard that allows compatible mobile devices to automatically detect and connect to available Wi-Fi hotspots without entering authentication information afresh.
Hotspot 2.0, also known as Wi-Fi Certified Passpoint or HS2, is a roaming standard for Wi-Fi networks. This Wi-Fi technology allows mobile devices to switch between Wi-Fi networks and cellular networks seamlessly without requiring additional authentication.
With Hotspot 2.0 technology, you can move from one Wi-Fi hotspot to another or from a cellular network to a Wi-Fi network and vice versa, without the need to select a network or enter your passwords again. The switch is automatic and does not require additional user sign-on.
The primary objective of Wi-Fi Hotspot 2.0 is to facilitate roaming for Wi-Fi networks similar to cellular roaming. Your HS2-compatible device can automatically connect to available public hotspots whenever you enter a Hotspot 2.0 area.
Hotspot 2.0 aims to offload the strain on cellular networks, reducing outages and improving quality and efficiency. It also cuts support costs, allowing communication service providers to increase their systems’ capacity and offer better and more efficient services.
That’s not all. Wi-Fi Hotspot 2.0 is more secure and convenient as it facilitates your device to detect and connect to real Wi-Fi networks when in public hotspot areas.
What is Wi-Fi Hotspot 2.0?
History of Wi-Fi Hotspot 2.0
Wi-Fi Hotspot 2.0 is a public access Wi-Fi specification by the Wi-Fi Alliance in collaboration with the Wireless Broadband Alliance. It first came out in 2011 with Hotspot 2.0 capable devices certified in 2012.
This Wi-Fi authentication technology is based on the IEEE 802.11u standard, tailored for interworking with external networks. IEEE 802.11u is a set of protocols designed to facilitate cellular-like roaming among Wi-Fi networks.
Following the advent of smartphones, tablets, and other wireless devices, data consumption has increased significantly.
Close to one billion Wi-Fi compatible devices hit the market every year, resulting in increased demand for internet connectivity. This increase means more strain on wireless and cellular networks.
It also causes safety concerns and inconsistent service quality since communication providers cannot meet the growing demand and guarantee the security of wireless networks.
The primary goal of Hotspot 2.0 is to address these challenges. Hotspot 2.0 reduces the burden on cellular networks by allowing roaming between Wi-Fi networks, and Wi-Fi and mobile networks.
Hotspot 2.0 also helps service providers to improve their systems’ capacity and band together with Wi-Fi providers for better service delivery.
How Does a Wi-Fi Hotspot 2.0 Work?
Wi-Fi Hotspot 2.0 works similarly to a cellular network by facilitating roaming services. It allows Wi-Fi users or devices to wirelessly connect to a Hotspot 2.0 whenever they are within range.
When traversing the globe with your mobile phone, you can activate or purchase a roaming subscription to allow your phone to connect to any cellular network while abroad. Wi-Fi Hotspot 2.0 works in a similar fashion.
The only difference is that it allows your wireless device to switch between different Wi-Fi networks when within range. It also lets you move from mobile data offered by your cellular network to a Wi-Fi 2.0 network.
The entire process is automatic and seamless. Wi-Fi Hotspot 2.0 technology facilitates network discovery, selection, and registration, allowing your device to automatically connect to the available wireless network without requiring additional authentication.
You do not have to enter your password or login credential again. Instead, Wi-Fi Hotspot 2.0 uses 802.11u protocols to transfer your pre-connection details to all available devices within range, eliminating the need to enter your authentication info again.
Nevertheless, connecting to Wi-Fi Hotspot 2.0 networks is not as smooth and seamless as it seems.
First, you must have a device that supports the IEEE 802.11u standard to allow for interworking with external networks. Moreover, you must be within a Hotspot 2.0 area to establish a connection.
The Wi-Fi profile applied on the wireless access point must have Hotspot 2.0 enabled. The network providers must configure the corresponding settings to allow the access point to advertise available hotspots and enable 802.11u-certified devices to discover and select the ideal Wi-Fi network.
Passpoint or Hotspot 2.0 compliant devices can search and discover Hotspot 2.0 operator networks within an area and automatically connect to the best network for which they have valid user credentials.

Wi-Fi Hotspot 2.0 Features
Wi-Fi Hotspot 2.0 facilitates cellular-like roaming for Wi-Fi networks, requiring minimal or no manual intervention as far as authentication is concerned.
This Wi-Fi 802.11u standard is an enhancement of the IEEE 802.11-2007 standard and it comes with various improved interworking features, including:
- Network Discovery and Selection
The Wi-Fi 802.11u standard facilitates automatic network discovery and selection. This Hotspot 2.0 feature uses a generic advertisement service to allow communication between your Passpoint-compliant devices and an external network without associating an access point. With this feature, your phone or tablet will detect, discover, and select the appropriate network to connect to.
- Inter-Carrier Wi-Fi Roaming
Wi-Fi Hotspot 2.0 supports inter-operator roaming, enabling new value streams and allowing for the expansion of the existing subscriber base. ISPs, mobile carriers, and hotspot providers can now work together to provide seamless Wi-Fi connectivity for new devices using SIM and non-SIM credentials for authentication. With inter-carrier Wi-Fi roaming, operators can determine if users are on mobile or Wi-Fi.
- Layer 2 Inspection and Filtering
Even though Wi-Fi Hotspot 2.0 is highly secure, it is not immune from security breaches. To mitigate the possibility of hacking, Wi-Fi Hotspot 2.0 uses Layer 2 inspection and filtering to protect mobile devices against hacking or cybersecurity attacks. This feature prevents data frames between devices from being delivered by the wireless network without going through inspection and filtering.
- P2P Cross Connection
