O
Avoid placing wireless components next to large metal objects such as
computer cases, monitors, and appliances. Metal objects reduce signal
strength.
O
Avoid placing wireless components close to electromagnetic devices, especially
those with frequencies in the 2.4-gigahertz (GHz) range. Devices such as
cordless phones, microwave ovens, radios, and televisions can interfere with
wireless transmission.
O
If you notice poor connection speed in an area, try moving your wireless
components closer together. Connection speeds will be slower if your wireless
components are very far apart from each other on the network.
O
Be aware that wireless signal range, speed, and strength can be affected by
interference from neighboring wireless networks.
Understanding Wireless Transmission Standards
802.11 is a series of wireless transmission standards developed by the Institute
of Electrical and Electronics Engineers (IEEE) for wireless local area networks.
Currently, four specifi cations make up the 802.11 series: 802.11, 802.11a,
802.11b, and 802.11g. The Microsoft Xbox Wireless Adapter conforms to
the latest specifi cation, 802.11g. The main features that distinguish these
specifi cations are connection speed and radio frequency.
The following table summarizes the four specifi cations in the 802.11 series.
Specifi cation
Connection speed
Radio frequency band
802.11
1 or 2 megabits per second (Mbps)
2.4 GHz
802.11a
Up to 54 Mbps
5 GHz
802.11b
Up to 11 Mbps
2.4 GHz
802.11g
Up to 54 Mbps
2.4 GHz
Note
The benefi t of the 2.4-GHz radio frequency band is that it allows for greater
range than the 5-GHz band. The drawback is that it is more susceptible to interference
from other devices, such as 2.4-GHz cordless telephones.
Because 802.11b and 802.11g use the same radio frequency band, your Xbox
wireless adapter is compatible with 802.11b devices. However, when you transfer
data between 802.11b and 802.11g devices, the connection speed is limited to
the 802.11b maximum of 11 Mbps.
Note
The Xbox wireless adapter is not compatible with 802.11a-only devices.
