SMCD3GNV Wireless Cable Modem Gateway User Manual
Configuring the Gateway's mso Interface
Lets you select between Mixed Mode and Green Field.
Mixed Mode = provides backward compatibility with IEEE 802.11n/a/g/b devices. (default)
•
Green Field = used for pure network of 802.11n access points and clients, taking full
•
advantage of the high-throughput capabilities of the 11n multiple-input multiple-output
(MIMO) architecture.
Select a channel bandwidth of 20 or 20/40.
20 = allows only single-channel operation (e.g., 20 MHz).
•
20/40 = allows both single channel operation (20 MHz) and the wider bandwidth operation
•
(40 MHz) by using two or more adjacent (contiguous channels). A 20/40 BSS is a wireless
network that allows a wider bandwidth operation mode. (default)
The guard interval is the period in nanoseconds that the Gateway listens between packets.
Choices are:
Long = 800 ns guard interval.
•
Short = 400 ns guard interval. (default)
•
Speeds up data transmission between the Gateway and 802.11n access points and clients by
allowing wireless workstations to send/receive data simultaneously, without contending for
shared medium. Default is enable.
Defines a second 20-MHz channel. 40-MHz stations can use this channel in addition to using
the control channel simultaneously.
Enables or disables aggregation of multiple MSDUs in one MPDU. Default is disable.
Enables or disables Auto Block ACL function. Default is enable.
Enables or disables the BA request function. Default is disable.
Select 1 or 2 from the pull-down menu. Default is 2.
Select 1 or 2 from the pull-down menu. Default is 2.
When checked, enables the Gateway's power-management features for optimizing battery
life. Default is checked.
Space Time Block Coding (STBC) is an 802.11n technique intended to improve the reliability
of data transmissions. With STBC, the data stream is transmitted on multiple antennas, so the
receiving system has a better chance of detecting at least one of the data streams. Choices
are:
Disable = Gateway does not transmit the same data on multiple antennas. (default)
•
Enable = Gateway transmits the same data stream on multiple antennas at the same time.
