Operation Modes and Connection Examples Access Point and Access Point WDS Mode The Access Point Mode is the default mode of the dev ice. It enables the bridging of wireless cli ents to wired network i nfrastructure and enable s transparent access and communi cation with each other . The illustration below shows a typical resources sharing appli cat[...]

S tation Mode In Station mode the device acts as a wi reless client. When connected to an access point, it creates a network link between the Ethernet network connected at thi s client device , and the wireless Ethernet network connected at the access point. In this example the workgroup PCs on the ethernet network connected to the Station device c[...]

S tation WDS Mode Statio n WDS mode is s imilar to Stat ion mode. The d ifference is Stat ion WDS must connect to access point confi gured to Access Point WDS (or RootAP) mode. Stat io n WDS is main l y us e for po i n t-to– poin t connection between 2 buildings or locations as far as several kilometer away. Point-to-Point Point-to-MultiPoint An [...]

Router Mode In Router Mode, the device also operates as a router. Either the wireless or Ethernet can be setup as WAN connection to a broadband modem. Wireless as W AN is known as Station + Router mode (or Wireless Routing Client mode) and Ethernet as WAN is known as AP + Router mode (or Gateway m o d e ) . Device supports several types of br oadba[...]

Repeater WDS Mode Repeater WDS Mode to mainly to extend the wireless range and cove rage of the wireless network allowing access and communications over places generally difficult for wireles s c lie nts t o connect to the network. In Repeater mode, the access point acts as a relay for network signals on the network by regenerating the signa ls it [...]

Install the Hardwar e This section will show you how to instal l the hardware of the access point. • Antenna Alignment The antenna alignmen t of the access point must first b e considered to ensure that the signal is strong. • Installation Direction After considering the antenna alignment, the direction in which the ac cess p o i n t i s f a c [...]

Antenna Alignment The physical environment of the antenna must be examined when aligning the antenna. Obstructions , available mounting locati ons, and other factors must be considered. Many objects such as forests, buildings, and hills , can obstruct the antenna, reducing the signal strength. The antenna can be installed at a height above such obs[...]

Installation Dir ection The directional antenna radiates the signal towards the front of the unit . T he unit sho ul d be ins tal le d in a position whereby the front of the unit faces the direction you wish to send the signal to. Therefore the direction you wish to send the signal to has to be consi dered before going on to the next step of starti[...]
