Standards-based Technology

The DGL-3420 Wireless Gaming Adapter utilizes the 802.11a, 802.11b and 802.11g standard.

The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54Mbps* within the 2.4GHz band. The 802.11a standard also increases the data rate up to 54Mbps,* but within the 5GHz band. Both 802.11a and 802.11g utilize 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 over your network without noticeable delays.This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions.

In addition to its compatibility with 802.11g and 802.11a devices, the DGL-3420 is compatible with 802.11b devices. This means that if you have an existing 802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that network will be compatible with the DGL-3420.

Installation Considerations

The D-Link DGL-3420 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:

Keep the number of walls and ceilings between the DGL-3420 and other network devices to a minimum - each wall or ceiling can reduce your D-Link wireless product’s range from 3-90 feet (1-30 meters). Position your devices so that the number of walls or ceilings is minimized.

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.

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.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise.

*Maximum wireless signal rate based on IEEE Standard 802.11a and 802.11g specifications. Actual data throughput rate will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead lower actual data throughput rate.
