TCP/IP
Transmission Control Protocol/Internet Protocol (TCP/IP) comprises
the backbone of the Internet. IP moves packets of data between
nodes while TCP verifies delivery from client to server. Every device
you hook up to your wireless router identifies itself with an IP
address. You are able to assign devices on your network with either
a static or dynamically assigned IP address.
Static IP Address
A static IP address is a fixed address that is assigned manually to a
device on the network. Static IP addresses must be unique and
cannot be shared, therefore they are used in situations where the
address should never change, like print servers or PC servers.
Dynamic IP Address
A dynamic IP address is a temporary IP address, dynamically or
randomly generated by a DHCP server. The address lasts only as
long as the server specifies, usually in the space of a day or two.
When the IP address expires, the client is automatically reassigned a
new IP address, ensuring smooth communication.
Understanding Wireless
Your Wireless Ethernet Bridge uses a radio transmission technology
defined by the Institute of Electrical and Electronics Engineers (IEEE)
called 802.11 or Wi-Fi (Wireless Fidelity). This 802.11 standard is
subdivided into distinct categories of speed and the frequency
spectrum used, designated by the lower case letter after the
standard.
For example, your Wireless Ethernet Bridge supports both the ‘b’ and
‘g’ specifications. The 802.11b standard specifies transmission rates
up to 11 Mbps while the 802.11g standard specifies transmission
rates up to 54 Mbps. The radio waves radiate out in a donut-shaped
pattern. The waves travel through walls and floors, but transmission
power and distance are affected. The theoretical distance limit is
1,000 feet (305 meters), but actual throughput and distance varies.
Both the 802.11b and 802.11g standards operate in the 2.4 GHz
range, meaning other electrical appliances also might interfere with
the Wireless Ethernet Bridge – televisions, radios, microwave ovens,
and 2.4 GHz cordless telephones. Therefore, positioning your
Wireless Ethernet Bridge where it encounters the least interference
gains the greatest benefit to maintaining a quality connection.
