ESS, in the context of Wi-Fi, is a basic building block of a wireless network. An Extended Service Set is essentially a set of interconnected Basic Service Sets (BSSs). A Basic Service Set is a group of stations (devices) that communicate with each other. When multiple BSSs are interconnected, they form an ESS. This allows users to roam between different BSSs while maintaining connectivity.

Here are some technical aspects related to ESS in Wi-Fi:

1. BSS (Basic Service Set):
   • A BSS is the basic building block of a Wi-Fi network.
   • It consists of a single access point (AP) and the devices (stations) associated with that AP.
   • There are two types of BSS: Infrastructure BSS and Independent BSS (IBSS).
2. Infrastructure BSS:
   • This is the most common type of BSS.
   • It includes at least one AP (access point) and one or more stations associated with that AP.
   • The AP serves as a central point for managing the communication within the BSS.
3. Independent BSS (IBSS):
   • Also known as an ad-hoc network.
   • In an IBSS, devices communicate with each other directly without the need for a central AP.
   • IBSS is typically used for peer-to-peer communication between devices.
4. ESS (Extended Service Set):
   • An ESS is a set of interconnected BSSs.
   • The interconnected BSSs enable users to roam seamlessly between different APs while maintaining connectivity.
   • Roaming is the ability of a device to move between different BSSs within the same ESS without losing network connectivity.
5. SSID (Service Set Identifier):
   • An SSID is a unique identifier for a BSS within an ESS.
   • It is essentially the name of the wireless network.
   • All devices within the same ESS use the same SSID.

The Extended Service Set (ESS) is a concept in Wi-Fi networking that allows multiple Basic Service Sets (BSSs) to be interconnected, providing a seamless wireless experience for users as they move between different access points within the same network.
