U-MEDIA Communications, Inc. Proprietary and Confidential 7 2. Introduction The WST-375L 2.4GHz Wireless 802.11n(DRAFT) Bridge is an high-performance, supports high-speed wireless networking at home, at work or in public places. Unlike most routers, the WST-375L provides data transfers at up to 300Mbps in 11n receiving mode. This bridge is also back compatible with 802.11g or 11b devices. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 11n’s speed when you mix 11n and 11b/g devices, but you will not lose the ability to communicate when you incorporate the 11n standard into your 11b/g network. You may choose to slowly change your network by gradually replacing the 11b/g devices with 11n devices. 2.1. Features  Compact form factor design  Affordable 11n product for easily migrating current 11b/g network to 11n network with higher data rate benefit  Supports IEEE 802.11n (draft 2.0) & 11b/g 2.4GHz wireless Local Area Network (WLAN) application  2.412~2.472GHz frequency band operation  Compliant with IEEE 802.3 & 3u standards  Support OFDM and CCK modulation  Delivers data rate up to 300 Mbps in 11n receiving mode.  Support one LAN port  Support WEP & WPA security  Support two printed antennas

U-MEDIA Communications, Inc. Proprietary and Confidential 103.3 Installation Considerations The TEW-638APB AP lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines: 1. Keep the number of walls and ceilings between the WST-375L and other network devices to a minimum - each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. 2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception. 3. Building Materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. 4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise.
