• Do not disassemble, repair or modify the wireless input unit.
• Do not peel off the radio frequency standard certification label. If the
label is peeled off, this may result in illegal modification.
Frequency Band and Channels
The WEE-1000A Wireless Input Unit is a radio wave transmission method used in
small wireless devices such as a PHS or cellular telephone. It uses the 2.4 GHz
radio frequency band and transmits data up to 11 Mbps. This band is
internationally assigned for wireless LAN IEEE 802.11b standard. The frequency
band is divided into 11 channels every 5 MHz. Each channel uses about 22 MHz
frequency bandwidth. However, all channels cannot be used at the same time
because overlapping channels interfere each other.
The WEE-1000 Wireless Input Unit covers channels 1 to 11 and uses up to three
non-overlapping channels (for example, channel 1, channel 6 and channel 11) at
the same time.
The 2.4 GHz frequency band, which is called ISM (Industry Science Medical), is
used for medical devices, ham radio and microwave ovens in addition to wireless
LAN. To prevent radio interference, the wireless input unit uses a spread spectrum
technology.
