User manual AIRLIVE WH-5400CPE

[. . . ] WH-5400CPE High Power Outdoor Solution User's manual 1 The Wireless Technology U Standard The Wireless Access Point utilizes the 802. 11b and the 802. 11g standards. The IEEE 802. 11g standard is an extension of the 802. 11b standard. It increases the data rate up to 54 Mbps (108Mbps in Super G mode) within the 2. 4GHz band, utilizing OFDM technology. This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format you're your network without noticeable delays. [. . . ] Data Rate ­ In data rate column you can select all bit rate supported in current operation mode. Default value is "best" means the system will automatically adjust the connection speed dynamically according to your current link status. Transmit Power ­ You can reduce RF output power by selecting Half (-3dB) / Quarter (-6dB) / Eighth (-9dB) / Minimum. To change transmit power may decrease your wireless signal coverage. Beacon Interval (20-1000) ­ This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Access Point to keep the network synchronized. A beacon includes the wireless LAN service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). Data Beacon Rate (DTIM) (1-16384) ­ This value indicated how often the Access Point sends out a Delivery Traffic Indication Message. Lower settings result in more efficient networking, while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to 29 enter sleep mode, thus saving power, but interferes with wireless transmissions. Fragment Length (256-2346) ­ This specifies the maximum size a data packet will be before splitting and creating a new packet and should remain at its default setting of 2, 346. A smaller setting means smaller packets, which will create more packets for each transmission. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications of this value are recommended. RTS/CTS Threshold (256-2346) ­ This setting determines how larget a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2, 346. Should you encounter inconsistent data flow, only minor modifications are recommended. Short Preamble ­ Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt of a data transmission. Some older wireless systems like 802. 11b implementation use shorter preambles. If you are having difficulty connecting to an older 802. 11b device, try to enable short preamble. Protection Mode ­ Protection Mode should remain default value (Auto) unless you are having severe problems with your 11g Wireless LAN products not being able to transmit to the Access Point in an environment with heavy 802. 11b traffic. To enable this function boosts the Access Point's ability to catch all 11g Wireless transmissions but will severely decrease performance. [. . . ] Passphrase - Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products. Port - The connection point on a computer or networking device used for plugging in cables or adapters. Roaming - The ability to take a wireless device from one access point's range to another without losing the connection. Router - A networking device that connects multiple networks together. [. . . ]
