1. 基本服务集(BSS):
基本服务集 (BSS) 是一种服务集,为无线组件或设备之间的连接和通信提供媒介。此处,媒体称为接入点 (AP)。 AP 是一种允许无线设备连接到有线网络的设备。
2. 独立服务集(ISS):
独立服务集 (ISS) 是一种服务集,它不需要任何介质来连接和允许无线组件或设备之间的通信。
BSS和ISS的区别:
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. |
