Link Overview

NP6 Antenna suppressing interference at 7 GHz NP6 -Force 4600C at 27 km

6 GHz with NP6

A renaissance of the wireless industry thanks to NetPoint in 6 GHz.

The link of NP6 and Force 4600c

For this PTP backhaul link at 6 GHz, it was carried out at a distance of 27.7 km from point A to point B where a signal level of -51 dBm was reached with a channel width of 20 MHz that gave us a result of 145 Mbps / 99.03 Mbps. Later, to obtain a higher level of capacity, the channel width of 160 MHz was used, which raised the signal level to -59 dBm but We obtained a capacity of 1239 Mbps / 733 Mbps which was verified vs mikrotik in simultaneous transmission of 723 Mbps / 721 Mbps.

NP6 from NetPoint and Cambium Networks up to 2 GB with an excellent return on investment for the ISP operator.

Without a doubt, one of the biggest challenges in wireless transmission is obtaining greater capacity, but it is a milestone to be able to transfer up to 2 GB. It is a new reality that will have to be taken advantage of and, above all, used efficiently with the integration in backhaul projects at distances from 0 to 100 km with the technology at 5.9 - 7.2 GHz frequencies for combined network users offered by the NetPoint NP6 antenna solution in integration with Cambium Networks Force 4600c. Why? without noise? Current systems allow the use of free and licensed bands on 6 sublicensed frequencies.

AP Send

Almost symmetrical transmission at both points of the link demonstrates the efficiency of the solution at a distance of 27 km in rainy weather.

Station Receives

Without a doubt, the AP sends us a total of 973 Mbps and the station receives 966 Mbps, something very acceptable for signal levels of -58 and the use of a 160 MHz channel.

Channel width 160 MHz

• Signal level -58 dbm

High performance on a single transmission channel = high isolation between ports

One of the successes achieved with the NP6 antenna was the high isolation in the ports, thanks to its excellent VSRW performance that ranges between 1.4 to 1.8, which makes it very stable throughout the entire band, in addition to avoiding energy losses between the transmitting radios and thus avoiding attenuations in the band and taking full advantage of the 32.5 dBm that the NP6 Antenna can offer.

The design, configuration with NP6 and Force 4600c:

The LinkPlanner by Cambium Networks calculation tools were used, as well as the configuration used for the radio was ePTP, which allows backhaul links to be made over distances from 0 to 31 km.

In the modulation, balanced was chosen, from experience we recommend that in the Network Input RSSI Threshold parameter you set -90 dBm and the selection of the channels that you are going to work with so that the radio can make quick changes.
