Difference between BSS and ESS

BSS and ESS are terms used in wireless networking to describe different types of wireless networks and their functions. A BSS is a wireless network made up of a group of devices within range of an access point and its AP, while an ESS is a network made up of multiple BSSs connected through a distributed system. Key differences between BSS and ESS include coverage, scalability, roaming, and definition. BSS has limited coverage, scalability, and roaming, while ESS provides better scalability, coverage, and roaming capabilities. Understanding these differences is important in choosing the right wireless network for your particular application.

Examine BSS and ESS

What is BSS?

BSS could be a group of gadgets that communicate with each other utilizing remote signals. It is the essential building square of a remote organization. In a BSS, one gadget acts as the Get to Point (AP), which acts as a bridge between remote gadgets and a wired arrangement. Other remote gadgets in a BSS communicate straightforwardly with the AP, and the AP oversees the transmission of information between the gadgets.

What is ESS?

ESS may be a group of two or more BSSs that are interconnected to make a single organization. ESS permits remote gadgets to move between distinctive BSSs inside the same arrangement without losing their association. The gadgets can proceed to communicate with each other as they move between distinctive BSSs. This empowers remote systems to cover bigger zones and gives a consistent network to remote gadgets.

The difference between BSS and ESS

The differences are highlighted in the following table −

Base of Difference




A group of remote gadgets that communicate with each other utilizing the same remote get to a point.

A group of one or more BSSs that are interconnected to create a bigger network.


One AP and one or more client devices interface to the AP wirelessly.

Multiple BSSs are connected to create a bigger arrangement.


Communication can occur straightforwardly between the client gadgets or can be steered through the AP.

Communication between diverse BSSs is accomplished through a wireless distribution system (WDS).


Roaming isn't backed between distinctive BSSs.

Allows client gadgets to consistently meander between diverse BSSs inside the same organization without losing the network.

Network Size

Limited to a single get-to-point and its related client devices.

ESS can back bigger arranged sizes by interconnection numerous BSSs.

Typical Use

Utilized in littler remote systems such as homes or little workplaces.

Utilized in bigger remote systems such as corporate or open Wi-Fi systems where consistent wandering is required.

The key contrasts between BSS and ESS are as takes after


A BSS is a wireless network consisting of an access point (AP) and a group of wireless devices that communicate with the AP. In a BSS, the AP acts as the central point of communication and control, and all communication between devices must go through the AP. An ESS, on the other hand, is a network of interconnected multiple BSSs in a distributed system. ESS allows devices to communicate with each other even if they are not within range of the same AP.


With BSS, the coverage area is limited to the reach of the AP. Devices out of the range of the AP cannot communicate with other devices within the BSS. In ESS, multiple BSSs are connected by a distributed system, so the coverage area is much larger. Devices can communicate with other devices within the same ESS even if they are out of range of the APs with which they are associated.


In BSS, devices cannot switch between different APs. Once a device is connected to an AP, it must stay within range of that AP to maintain connectivity. ESS allows devices to switch between different BSSs as long as they are connected to the same distributed system. This increases the mobility and flexibility of wireless devices.


BSS has limited scalability because it can only support a limited number of devices within the range of an AP. ESS allows multiple BSSs to be connected to the same distributed system, improving scalability and supporting more devices.


BSS could be a wireless network comprising of a single AP and a group of gadgets inside the extent of that AP, whereas ESS could be an arrangement comprising numerous BSSs associated through a dissemination framework. BSS has a restricted scope, whereas ESS includes a bigger scope range. BSS does not bolster meandering between distinctive APs, whereas ESS permits gadgets to wander between distinctive BSSs. At long last, BSS has restricted adaptability, whereas ESS permits more noteworthy adaptability and the capacity to back a bigger number of gadgets. Understanding these contrasts is vital for selecting the fitting remote organizer for a given application.
