Overview
WMM - WiFi MultimediaThe AP-800 implements intelligent wireless traffic prioritization for the most efficient management of wireless traffic by using the Wi-Fi Multimedia standard (WMM). WMM defines Quality of Service (QoS) in Wi-Fi networks. It is a precursor to the upcoming IEEE 802.11e WLAN QoS standard, intended to improve timing critical applications such as audio, video and voice applications over WiFi. WMM adds prioritized capabilities to Wi-Fi networks and optimizes their performance when multiple concurrent applications, each with different latency and throughput requirements, compete for network resources.
Dual-Band UpgradableBy the addition of a simple plug in 'N65' USB module, the AP-800 can operate in the alternative '5.8Ghz' band simultaneously with the standard 2.4Ghz band. As it's simultaneous, you can still use the 2.4Ghz band for some devices. The 5.8Ghz band is much less widely used and therefore less congested. Your PC needs to support this band to take advantage but if it doesn't you can add the same 'N65' USB 'dongle to the PC to add it. The dual-band upgrade should be available by the end of 2011 (estimated); price to be confirmed. AP-700 vs. AP-800 Comparison
WDSWDS & Repeater ModesThe DrayTek AP-800 can act as a standalone wireless access point, ideal for adding wireless connectivity to an existing LAN but also operates in several other wireless modes to provide enlarged wireless coverage or wireless bridges to other parts of your LAN. Many different configurations are possible: Bridge ModeThis mode joins two parts of the same logical network which cannot be otherwise connected by cables, for example between two adjacent buildings. As the AP-800 has a built-in 4-Port switch, you can then connect up to 4 wired devices/PCs directly to it:
Repeater ModeAs a repeater, the AP-800 can extend the wireless coverage of a network. You can add multiple units to extend the range in multiple directions or multiple hops (for best performance, more than two is not recommended due to latency and channel congestion which can result).
In the diagram below, there are two AP-800's to extend the range in different directions:
Station ModeIn 'Station Mode' a remote station (computer or other device) can connect to the AP-800 using a regular ethernet cable, but the AP-800 connects to the remote LAN over wireless. The AP-800 has a built-in 4-port Ethernet switch so you can connect up to 4 client devices directly by wired Ethernet (100BaseT RJ45):
Station mode can also be used for games consoles or other Multimedia devices:
Dual-LANDual-LANThe AP-800 can support two completely independent LANs; each is connected via its own independent RJ45 Ethernet interface. There are Ethernet RJ45 interfaces for LANA (4 ports) and LAN B (one port). These networks remain completely isolated from each other. Each LAN is assigned its own separate Wireless SSID so they remain separated even on the Wireless LAN. This is the equivalent of having two completely separate access points and ideal for public and private networks in the same location or wireless LANS for two separate companies. Having two physical LAN interfaces provides a much simpler alternative to using tagged VLANs (which requires additional switching hardware with VLAN support) and a Radius server for authentication. It is also much easier/quicker to set up.
PoEPower-over-EthernetThe AP-800 supports PoE (Power over Ethernet) as standard (built-in) so if the AP-800 is connected to a PoE enabled Ethernet switch or PoE injector, you don't need any local power to the unit (power supply) - the AP-800 will take its power from the Ethernet cable. This is ideal for situations where you do not have mains power available in the exact location where you want to install the AP-800 or just for general aesthetic neatness, perhaps where the AP-800 is installed somewhere prominent:
The AP-800 is also supplied with an AC/DC mains PSU for installations where you are not using PoE. User AuthenticationUser AuthenticationFor additional security, wireless access can be restricted to authorised users only by use of a unique username and password for each user. This is in addition the encryption provided by WEP/WPA etc. When the user first opens their wireless connection, the AP-800 will request their username/password and not permit access to the LAN or Internet without it. The AP-800 can use an external radius server to hold user credentials but also has its own built-in radius server to store up to 96 users. The AP-800's built-in Radius server can also act as a server to additional devices (such as another AP-700, meaning that you don't need to set up the same users up on several units).
