Infrastructure Mode wireless networking, bridges (joins) a wireless network to a wired Ethernet network. The network topology consists of wireless stations and (one or more) Wireless Access Points (WAP). This is the most commonly used mode.
All the wireless stations communicate with each other by first going through a WAP. Wireless devices can either communicate with each other or can communicate with a wired network to get access to network services or the Internet.
Vigor wireless routers play the role of an Access Point (AP) connecting many wireless clients or Stations. All the stations will share the same Internet connection via the Vigor wireless router.
Infrastructure mode has better coverage, due to several factors:
- Wireless range is measured as a circle around the WAP to each device. A PC at one end of wireless range can communicate with another PC at the other end of wireless range (where the PC to PC distance is too great).
- A WAP may have more range, due to having more powerful transmitter/receiver than the individual PC cards.
Compared to ad-hoc wireless networks, infrastructure mode networks offer the advantage of scalability, centralized security management and improved reach satisfying the need of large-scale networks. Multiple Access Points combined with a distribution system (such as Ethernet) support the creation of multiple radio cell that enable roaming throughout the network
