1. Introduction 1 1. Introduction 1.1 Overview The AC.TOP is a ceiling mount wireless multi-function AP based on 1200Mbps 2T2R Wireless AC+ b/g/n MIMO standard radio technologies. It is 2.4G/5G dual band concurrent. The Wireless Access Point is equipped with one Gigabit Auto-sensing Ethernet ports for connecting to LAN and also for cascading to next Wireless Access Point. It has built-in 802.3af PoE port for installation up to 100 meter away from the power source. 1.
1. Introduction 1.3 Features 1200Mbps 802.11AC+b/g/n Standard Up to 23dBm output power (limited to 20dBm in EU) Built-in MIMO Antennas 8MB Flash and 64MB SDRAM 2 wireless multi-function modes: AP, WDS repeater 1 x 10/100/1000 Mbps Ethernet Port with IEEE 802.
1. Introduction 1.4.2 WDS Repeater Mode In WDS Repeater mode, the AC.TOP functions as a repeater that extends the range of remote wireless LAN. In this mode, the remote Access Point must have WDS (Wireless Distribution System) capability. If you require the PC’s MAC addresses to be preserved when the data pass through the Repeater, it is necessary to use the WDS Repeater mode. Because the radio is divided into WDS + AP mode, the Repeater mode will have less performance and distance. 3 AirLive AC.

A DDNS service provides each user account with a domain name. A router with DDNS capability has a built-in DDNS client that updates the IP address information to DDNS service provider whenever there is a change. Therefore, users can build website or other Internet servers even if they don't have fixed IP connection. DHCP Dynamic Hosting Configuration Protocol.
9. Wireless Network Glossary ESSID (SSID) The identification name of an 802.11 wireless network. Since wireless network has no physical boundary liked wired Ethernet network, wireless LAN needs an identifier to distinguish one network from the other. Wireless clients must know the SSID in order to associate with a WLAN network. Hide SSID feature disable SSID broadcast, so users must know the correct SSID in order to join a wireless network.
9. Wireless Network Glossary IGMP Snooping Internet Group Management Protocol (IGMP) is a Layer 3 protocol to report IP multicast memberships to neighboring multicast switches and routers. IGMP snooping is a feature that allows an Ethernet switch to "listen in" on the IGMP conversation between hosts and routers. A switch support IGMP snooping has the possibility to avoid multicast traffic being treated as broadcast traffic; therefore, reducing the overall traffic on the network.
