Quanta 5 is a wireless point-to-point solution with an impressive performance 70 is a brand new addition to the Infinet Wireless Point-to-Point product portfolio, which delivers real throughput of up to  460 480 Mbps in the 40 125 MHz bandwidth, a packet perfomance is up to 900 930 000 pps. Quanta 5 70 family is based on the newest InfiNet Infinet Wireless proprietary Octopus SDR hardware platform.It operates  Wireless device operates in frequency range from 4900 MHz to 6000 MHz and supports the wide range of channel width between 3.5 MHz and 40 MHz. Wireless device can be used with:

  • a dual polarization integrated antenna with an antenna gain 23 dBi;
  • an external antenna connected to two N-type ports using low-loss RF cables

and operates in LOS and non-LOS conditions. SC-FDE radio technology is used for data transmission.

Radio

...

70.5-76 GHz, it has much lower utilization as compared to the 5 GHz license-exempt frequency bands, but offers much better propagation than 60 GHz (V-band). This spectrum is lightly licensed or sometimes even unlicensed in a number of countries and therefore enables the deployment of high-density networks in urban areas, with nearly zero interference.

Radio

  • Automatic Modulation Control (AMC) – modulation control algorithm selects the most appropriate modulation-coding scheme at each polarization and each end of the link in order to maximize the link performance.Hybrid-FDD (split-frequency mode) – separate allocation of downlink and uplink channels to utilize the least congested frequency channel at each end of the link.

  • Automatic Repeat Request (ARQ) – a technology which enables packet re-transmission in case of previous unsuccessful delivery, allows to achieve reliable connectivity even in highly congested spectrum.

  • Instant DFS – a set of algorithms operating on top of the mandatory DFS/Radar detection/LBT, providing background spectrum scanning and zero-downtime channel reselection in case of congestion or radar detection. For uplink and downlink traffic, different frequencies can be selected to achieve optimum performance.

  • Automatic Transmit Power Control (ATPC) – a technology which allows to limit the overall power system mode, which takes into account the antenna gain and losses in the RF cable.

  • Automatic range detection - the guard interval optimal for the actual distance is automatically determined.

Networking

  • VLAN support is an important tool which is used to isolate and filter traffic flows.

  • STP support allows to avoid network loops.

  • IEEE 1588v2 support provides synchronization between devices via the wired network segment.

  • Stacked VLAN support (Q-in-Q) avoids the limitation in the number of available VLANs (4096), which can be useful for large networks. In addition, Q-in-Q allows you to organize L2 channels within a limited VLAN list, which is widely used in provider networks and on leased communication channelsJumbo frames support - available Ethernet frame size is up to 9038 bytes.

  • Due to QoS support, traffic prioritization is available in accordance with the 802.1p (8 queues), ensures that the most important data arrives with priority.One of the network mechanisms to optimize bandwidth by reducing the share of overhead for service headers are Jumbo frames with size up to 9038 bytes.

Distance

Quanta 5 70 has a link budget of up to 168 dB175 dB using model Q70-39 and up to 197 dB using model Q70-50. This budget allows it to achieve reliable connectivity at up to 40 10 km in clear line-of-sight conditions , as well as provides sufficient margin for near- and non-LOS deployments at shorter distances. Transmit power at the highest modulations is also one of the key performance metrics, allowing Quanta 5 to achieve the highest performance over long distances and in noisy spectrum. The Quanta 5 transmit power at QAM256 is up to 24 dBmusing model Q70-39 and up to 20 km using model Q70-50. Supporting 40 non-overlapping frequency channels and built with an integrated antenna having a pencil-wide narrow beam, Quanta 70 has minimal or zero impact from external interference, allowing it to achieve much higher density of collocated wireless units when compared to lower frequency bands.
