Description Tenda A9 Wireless N300 Range Extender Tenda A9 Wireless N300 Range Extender is a wireless N300 universal range extender, specially designed to extend the existing WiFi coverage and improve the signal strength. With the one-button extension, smart signal LED, wall-mount design and universal compatibility, it is easy for users to boost wireless networking. A9 is an ideal choice for you to eliminate WiFi dead zones and optimize your networking. Main Features 300 Mbps 802.11n speed. 2*3 dBi external antennas boost the signal to extend WiFi coverage up to 200㎡. One button extension help to extend WiFi coverage easily. Smart WiFi Signal Strength LED help to choose optimum location easily. Compatible with main brands 802.11n standard wireless routers and WiFi DSL. Support SSID Hiding Strong Signal and Wide Coverage With 2*3dBi external antennas, A9 can provide a strong signal and extend the existing WiFi coverage to 200㎡. Also, by optimizing the software and hardware, the anti-interference ability is improved much, so that A9 can provide stable signal and guarantee large WiFi coverage. Whole Coverage for Large Multi-rooms Flat For the large multi-rooms flats, a single wireless router can not provide a perfect WiFi environment and there are always WiFi dead zones at the balcony, study or bathroom and so on. It is easy to realize WiFi coverage for the whole flat by placing an A9 at the right place according to the signal LED (the LED should be GREEN) and boosting the signal to the whole flat. Whole Coverage for Multi-floor villa A9 can realize WiFi signal extension both horizontally and vertically. In villas, the load-bearing wall always causes serious WiFi signal loss, making the WiFi signal weak on the other floor. By optimizing the software, hardware and antenna gain, A9’s vertically signal-receive ability is 30% better than likewise products. This guarantees the whole WiFi coverage of a multi-floor villa. One Button Extension Designed with an extending button, A9 can extend the wireless router’s WiFi immediately by pressing the wireless router’s WPS button once, and within 2 minutes, pressing the Range Extender button. Just plug and play and it is easy to set up. Smart Signal LED Indicator Once connected with the existing WiFi, it is easy to find the best location for the extender according to the smart WiFi signal LED indicator so that A9 can achieve the best coverage and works better. Seamless Coverage When the client is moving, the device can re-connect to a stronger WiFi signal automatically without disconnection, which helps clients to enjoy ultra-fast WiFi anywhere in the whole house. Universal Compatible with All Brands Wireless Devices Based on 802.11 n/g/n standards, A9 can work with almost all the b/g/n wireless routers and WiFi DSL Specifications Data Rate 802.11b: 11 Mbps 802.11g: 54 Mbps 802.11n: 300Mbps Standard b'&' Protocol IEEE802.11b,IEEE 802.11g, IEEE 802.11n Modulation 802.11b: DSSS / BPSK / QPSK / CCK 802.11g: OFDM / DSSS / BPSK / QPSK / CCK 802.11n: OFDM / DSSS / BPSK / QPSK / CCK Frequency 2.412~2.484 GHz Power 16dBm Reception Sensitivity 11b: -95dBm 11g: -76dBm 11n: -73dBm Antenna 2 *3dBi external non-detachable Standard Version RFC768 UDP RFC791 IP RFC792 ICMP RFC793 TCP Channel Bandwidth: 20/40MHz (default) Working Mode Repeater Mode (Client + AP) Wireless Security Encryption Mode: Mix WPA-PSK/WPA2-PSK WPA Algorithm: TKIP DHCP Server Support System Tool Upgrade Reset to Factory Default Login Password System Log Reboot Weight GW 13KG (FCL) Dimension 111 * 56 * 47.7mm Temperature Operating Temperature:0ºC~40ºC Storage Temperature:-40~70℃ Humidity Operating Humidity:10%~90%, non-condensing Storage Humidity:5%~90%, non-condensing Looking for other networking products?
