3. Wireless Basics
TRENDware wireless products are based on industry standards to provide
easy-to-use and compatible high-speed wireless connectivity within your home,
business or wherever a wireless network is available. Strictly adhering to the IEEE
standard, the TRENDware wireless family of products will allow you to access the
data you want, when and where you want it. No longer will you be limited to one
location or forced to run new wiring through your home or office. You will be able to
enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless LANs are
used increasingly in both home and office environments, and public areas such as
airports, coffee shops and universities. Innovative ways to utilize WLAN technology
are helping people to work and communicate more efficiently. Increased mobility
with the absence of cabling and other fixed infrastructure have proven to be
beneficial for many users.
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems, support the same
protocols as Ethernet adapter cards. For most users, there is no noticeable
functional difference between a wired Ethernet desktop computer and a wireless
computer equipped with a wireless adapter other than the added benefit of the ability
to roam within a wireless-cell. Under many circumstances, it may be desirable for
mobile network devices to link to a conventional Ethernet LAN in order to use
servers, printers or an Internet connection supplied through the wired LAN. A
Wireless Access Point (AP) is a device used to provide this link.
People use wireless LAN technology for many different purposes.
Mobility - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions based
on real-time information can significantly improve worker efficiency.
Low Implementation Costs WLANs (Wireless Local Area Networks) are easy
to set up, manage, change and relocate. Networks that frequently change, both
physically and logically, can benefit from WLANs ease of implementation.
WLANs can operate in locations where installation of wiring may be impractical.
Installation Speed and Simplicity - Installing a wireless LAN system can be
fast and easy and can eliminate the need to install cable through walls and
ceilings.
7
Network Expansion - Wireless technology allows the network to go where
wires cannot go.
Reduced Cost-of-Ownership - While the initial investment required for
Wireless LAN hardware might be higher than the cost of wired LAN
hardware, overall installation expenses and life-cycle costs will be
significantly lower. Long-term cost benefits are greatest in dynamic
environments requiring frequent moves, adds, and changes.
Scalability - Wireless Local Area Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications and
installations. Configurations are easily changed and range from peer-to-peer
networks suitable for a small number of users to full infrastructure networks
of thousands of users that allow roaming over a broad area.

Standards - Based Technology
The IEEE802.11b standard-based technology assures that the TRENDware
Products are interoperable with existing compatible 2.4GHz wireless
technology. This means you will be able to transfer large files quickly or even
watch a movie in MPEG format over your network without noticeable delays. The
technology works by using multiple frequencies in the 2.4GHz range at speeds
up to 22Mbps. TRENDware products will automatically sense the best possible
connection speed to ensure the greatest speed and range possible with the
technology.
Installation Considerations
Designed to go up to 1,312 feet (400 meters) outdoors and up to 328 feet (100
meters) indoors, the TRENDware TEW-310APB lets you access your network
with your laptop computer from virtually anywhere. Keep in mind,
However,that the number, thickness, and location of walls, ceilings or other
8
objects that the wireless signal must pass thru may limit range. Typical ranges
vary depending on the types of materials and any background RF (radio
frequency) noise in your home or business. The key to maximizing range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the wireless Access
Point and your receiving device to a minimum - Each wall or ceiling can
reduce your TRENDnet Wireless product's range from 3-90 feet (1-30
meters.) Position your Access Points, Internet Routers, and computers
so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between Access Points, Internet Routers, and
computers. Awall 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! Try to make sure that the Access Points
and Adapters are positioned so that the signal will travel straight through
a wall or ceiling for better reception.
3. Building Materials make a difference - A solid metal door or aluminum
studs may have a negative effect on range. Try to position Access
Points, and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
4. Make sure that the device's antenna is positioned for best reception by
using the software signal strength tools included with your product.
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that may generate extreme RF noise.
For the average home, signal range should not be an issue. If you experience
low or no signal strength in areas of your home that you wish to access, consider
positioning the Access Point in a location directly between the computers with
wireless adapters. Additional Access Points can be connected to provide better
coverage in rooms where the signal does not appear as strong as desired.
Using radio frequency (RF) technology, WLANs (Wireless LocalArea Networks)
transmit and receive data over the air, minimizing the need for wired
connections. Thus, WLANs combine data connectivity with user mobility, and,
through simplified configuration, enable movable LANs.

4. Getting Started
For the price of a single IP Address from your Broadband Internet Service
provider you can share the Internet with all the computers on your local network,
without sacrificing speed or security, using TRENDware networking products.
An Infrastructure network contains an Access Point. The Infrastructure
Network example shown on the below contains the following TRENDnet
network devices:
WirelessAccessPoint (TEW-310APB) (DHCPenabledat default)
Ethernet Broadband Router (TW100-S4W1CA) (DHCPenabledat default)
Notebook computer with a wireless adapter (TEW-301PC)
Desktop computer with a wireless adapter (TEW-303PI)
Cable modem or DSL Modem
DHCP stands for Dynamic Host Configuration Protocol. It is a protocol
for assigning dynamic IP addresses “automatically”.With a DHCP-
capable gateway/router, there is no need to manually assign an IP
address to each computer in the network.
Right out of the box, with its default settings, the TEW-310APB will
automatically connect with other TRENDnet products.
Please note: If you have a DHCP-capable router, please configure
the TEW-310APB to disable its DHCP Server and enable its DHCP
Client
If you need to assign IP Addresses to the computers on the network,
please remember that the IP Address for each computer must be in
the same IP Address range as all the computers in the network, and
the Subnet mask must be exactly the same for all the computers in the
network.
For example: If the first computer is assigned an IP Address of
192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second
computer can be assigned an IP Address of 192.168.0.3 with a Subnet
Mask of 255.255.255.0, etc.
IMPORTANT: If computers or other devices are assigned the same IP
Address, one or more of the devices may not be visible on the network.
