Difference between BSS and ISS
1. Basic Service Set (BSS) :
Basic Service Set (BSS) is a service set that provide medium for connecting and allowing communication among wireless components or devices. Here, medium is referred as Access Point (AP). AP is a device that allows wireless devices to get connect to wired network.
2. Independent Service Set (ISS) :
Independent Service Set (ISS) is a service set that does not require any medium for connecting and allowing communication among wireless components or devices.
Difference between BSS and ISS :
BSS | ISS |
---|---|
In BSS, wireless devices communicate through medium. | In ISS, wireless devices communicate directly with each other without any medium. |
BSS basically contain only one AP. | ISS does not require any AP and therefore no AP is present in ISS. |
BSS usually provide short range wireless communication as compared to ISS. | ISS usually provide long range wireless communication as compared to BSS. |
BSS does not support mobility i.e. user or client cannot move freely from one place to another. | ISS supports mobility i.e. user or clients can move freely from one place to another while communicating with each other without any interruption. |
Clients or users are connected through a medium i.e. AP. | Clients or users are connected directly with each other without any need of AP. |
Though BSS is easy, but it is rarely used. | ISS is mostly used as compared to BSS. |
BSS usually set up connection between many wireless devices. | ISS usually set up connection between two or more fixed devices or laptops that needed to exchange files. There is no other network present. |
It is also known as Infrastructure more. | It is also known as ad-hoc mode or peer to peer mode. |
