iii. Product Review

1. Connection Mode

◎Infrastructure Mode

Infrastructure mode needs an access point to establish the network, which can provide wireless

accesses within valid range for users to communicate with others or transmit data with a wired

network. There are several benefits of Infrastructure networking:

√ Roaming: a wireless LAN enabled computer can physically move from the operating

range of one access point to the other without losing connection. There is a quick

association made between new access point and wireless device as the computer traverses

from the coverage of one access point to another.
√ Range Extension: each wireless LAN enabled computer within the range of access
point can communicate with other wireless LAN enabled computers within the effective

range from the access point.
√ Wired to wireless LAN connection: the access point will establish a bridge between

wireless LAN and other wired counterparts.
