INFRASTRUCTURE
Infrastructure mode
Ad-Hoc mode
Ad-Hoc mode is a Peer-to-Peer mode. Without an AP, computers can also
connect to each other by SP907BB. With this mode, computers are able to share
data or connect to the Internet if one of them is already connected to.
Ad-Hoc Mode
Infrastructure
Mode
Infrastructure mode including an AP, unlike Ad-Hoc mode, enabling users to best
utilizes the frequency bandwidth of the AP.
This mode enables users to integrate wired and wireless infrastructures. Through
APs, wireless users are able to access wired resources, for example: Internet,
database, and printers.
Advantages
Comparing to Ad-Hoc mode, Infrastructure mode has the following advantages:
9
9
9
Longer distance: Through AP, the wireless access distance is longer.
Roaming: The wireless devices can move within the AP support area.
Integration of wired and wireless environment.

5. Appendix
1. Operation Mode:
SP9007BB has two modes, ‘Infrastructure’ and ‘Ad-Hoc’. The default setting is “Infrastructure”.
(Please refer to the Product Introduction)
2. Channel:
The channel setting should follow the regulation of the local government. For ‘Infrastructure’ mode,
the channel does not need to be set. It will automatically change to the same channel as AP’s. In
‘Ad-Hoc’ mode, users can change the channel to match the connected computer.
3. SSID:
When SP907BB is in Ad-Hoc mode, all connecting SP907BB should have the same SSID. When
SP907BB is in Infrastructure mode, the SSID will change to the same as AP’s SSID.
Important: Capital and non-capital are different words in SSID setting.
4. Tx Rate:
It determine SP907BB’s transmitting rate. There are 5 rated to choose, 1, 2, 5.5, 11Mbps, and
Auto. The default setting is “Auto”.
5. Int. Roaming: Its default setting is ‘Disable’, and does not need to be adjusted.
6. Radio:
The default setting is ‘ON’. It means to stop the SP907BB’s RF function. If your WLAN card is
embedded, you can stop its function by turning the Radio “ON”.
7. Encryption:
SP907BB provides 64/128bits encryption. Choose “disable”, if you do not need this function.
When using Encryption, there are two configurations to setting:
„
Choose from encryption key 1~4 to encrypt.
9
9
For 64bits encryption:
Using letters & numbers: 5 digits (“a-z”,”A-Z”,”0-9”)
Hexadecimal: 10 digits (“a-f”,”A-F”,”0-9”)
For 128bits encryption:
Using letters & numbers: 13 digits (“a-z”,”A-Z”,”0-9”)
Hexadecimal: 26 digits (“a-f”,”A-F”,”0-9”)
„
Choose the Authentication type from open system, share key, and auto type. The default
setting is ‘auto’.
8. PREAMBLE:
This function determines the PREAMBLE TYPE that physical layer’s PLCP will use. There are
three modes to choose: LONG, SHORT, and AUTO. The default setting is AUTO, and the system
will automatically choose the optimized mode.
9. Tx Power Level (mW): Does not open to change.

10. Fragmentation Threshold:
This configuration determines whether needs to fragment the Frame during transmit. When
fragment, if the transmit fell, computer only resent the fail frame instead of the whole file again.
When the frequency band used is not clear, i.e. The S/N ratio is low, transmit is easier to fail.
Under this situation, fragmentation is a good way to increase efficiency.
11. RTS/CTS:
When frame smaller than the RTS Threshold value, the SP907BB will automatically transmit the
frame if the channel is available. If the channel is used, SP907BB will follow the 802.11b
regulation that would ask the receiving device whether to send the frame. This will take more time
for devices to check with each other, but it also prevents the loss of frames.
12. Power Save:
Determine whether to use power saving mode. The default setting is ‘Disable’.
