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.
