Product Overview
Standards-Based Technology
The TW-EA514 Wireless Router utilizes the 802.11n standard. The IEEE 802.11n standard
is an extension of the 802.11g standard. It increases the data rate up to 300 Mbps 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 over your network without noticeable delays. This
technology works by transmitting high-speed digital data over a radio wave utilizing
OFDM
( O rthogonal F requency D ivision M ultiplexing) 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.
Installation Considerations
The TW-EA514 Wireless Router 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
Keep the number of walls and ceilings between the TW-EA514 and other network devices
to a minimum - each wall or ceiling can reduce your TW-EA514 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. Position the 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 (radio frequency) noise.
