Eion LibraPlus 5845, Руководство пользователя, Страница: 53 / 140

When AP and station coexist, hardware beacon timers are disabled for the station mode. This is necessary
because concurrent AP and station operation implies the station should not modify the TSF clock for
the APs.

4.2.4.1. Setting Transmit Power
The LibraPlus 5845 hardware is available in two different power configurations. It is important to
verify the specific LibraPlus model you are working with before setting the power level in the firmware.
Higher transmit (TX) power essentially translates into a higher signal power at the receiver. Having a
higher signal-to-noise ratio (SNR) at the receiver reduces the bit error rate of a digital communication
link. A higher SNR can also allow a system that uses link adaptation to transmit at a higher data rate,
resulting in a system with greater spectral efficiency.
The greater the TX power, the higher the supported data rate or the more reliable the link at a given
data rate. However, transmitting at unnecessarily high power may introduce excessive interference.
The maximum transmit power is limited according to regulatory region.

Arguments.
power Peak power value in dBm, integer.
Example 4.10. Setting Transmit Power
EION: interface Wireless 0 tx-power 26
The tx-power value is set to 26 dBm.
4.2.4.2. Setting Distance Parameter
The link distance parameter allows the user to tune ACK timeout which optimizes performance for a
particular distance.
The Link Distance parameter is expressed in metres. This number must be divisible by 300.
