4.0 Configuration
Select HT20 for a 20MHz channel, or HT40 for a 40 MHz
Channel. The 40MHz channel is comprised of 2 adjacent
20MHz channels and the + and—designate to use the higher or
lower of the adjacent channels.

The Channel-Freq setting allows configuration of which channel to operate on, auto can be
chosen where the unit will automatically pick a channel to operate. If a link cannot be
established it will try another channel.

The Wireless Distance parameter allows a user to set the
expected distance the WiFi signal needs to travel. The default
is 10km, so the VIP4G will assume that the signal may need to
travel up to 10km so it sets various internal timeouts to account
for this travel time. Longer distances will require a higher
setting, and shorter distances may perform better if the setting
is reduced.

Advanced Capabilities (Only shown if box is checked)
MPDU Aggregation (Enable/Disable) - Allows multiple data frames to be sent in a single
transmission block, allowing for acknowledging or retransmitting if errors occur.
Short GI (Enable/Disable) - GI (guard interval) is the time the receiver waits for any RF
reflections to settle before sampling data. Enabling a short GI (400ns) can increase throughput,
but can also increase the error rate in some installations.
