Radio
• Transmit power – can be varied between -5 dBm to +23 dBm
• To achieve high distance and high throughput at low EIRP (33dBm as per ETSI) a high
gain antenna (29 dBi) with low transmit power of the radio is recommended.
• Setting up a radio at high Transmit power may result into Amplifier saturation, radio tends
to distort EVM. So we suggest that you try to use lower than the maximum power level.
• Maximum recommended Transmit power in 5GHz band is 18dBm and in 2.4 GHz band it
is 20 dBm
• Transmit power and RSSI are important criteria for getting a stable link
Throughput Optimizer
• The default value for the Throughput Optimizer is 6
• Throughput Optimizer settings is used to optimize the wireless link throughput
• Smaller
"Throughput Optimizer" value means more stable link
Performance
The primary reason for implementing RTS/CTS is to minimize collisions and retransmission in a highly
overcrowded
.
Fragmentation
• Fragmentation can be used to avoid retransmission of the packets.
• The fragment size value can typically be set between 256 and 2,048 bytes.
• Fragmentation can improve throughput if the fragmentation threshold is set just right
value.
Range
• Maximum range of sB3010 is 50 Miles (Repeater mode)
• 6 Miles can easily achieved with 23 dBi antenna
• More than 6 miles can be achieved by using high gain antennas.
RSSI
•
Recommended RSSI value of -75 dB or better for optimal performance .
Profile manager
•
With Profile manager one can save/load multiple Operating profiles on the device.
•
The Profile Calendar will automatically activate them at defined times.
•
Optimal bandwidth utilization of the bandwidth on the basis of various time intervals as
per the traffic pattern of the customer can be achieved through pre-scheduling of profiles
Bandwidth Controller
• Bandwidth Controller will define the Maximum upload Wireless Throughput (Kbps) for a
radio.
• Maximum bandwidth for sB3021 is 20 & 30 Mbps in Repeater and Link Aggregate mode
respectively.
