High Capacity 11GHz Microwave Links with 1024QAM

CableFree FOR3 Microwave Links offer 881Mbps Full Duplex using 1024QAM, 112MHz Channels in 11GHz Microwave Band

The 11GHz version of CableFree FOR3 is ideal for Long Distance Backbone links for ISPs, Wireless ISPs (WISP), 4G/5G Operator for LTE Backhaul.  In this demonstration you can see CableFree FOR3 Microwave Test Results for operation in the 11GHz Band.  Our demonstration shows 881Mbps Full Duplex net throughput using 1024QAM modulation in 112MHz channels.This demonstration shows the clear advantages of a telecom carrier-grade FDD (Frequency Division Duplex) modem radio, which offers dedicated throughput and genuine Full Duplex capacity.  Many operators use these links to upgrade from existing 5GHz MIMO radios when the capacity available on 5GHz is saturated, or interference levels too high for reliable operation.

Link Aggregation for Higher Capacity

CableFree Microwave Links can be aggregated for higher capacity:  A 2+0 configuration of this radio in 11GHz would offer 1782Mbps Full Duplex net capacity.

How the Demo was created:

The CableFree FOR3 radios were placed in a lab with suitable attenuator material between the waveguides to simulate long distance/range & attenuation.  A pair of routers were placed either end of the link, to generate and receive test packet streams.  These routers are capable of saturating a 1Gbps link therefore ideal for this test.  Due to the nature of Telecom Microwave FDD modems, the same full capacity is available at range where suitable antennas are used.  Longer range links require larger antennas to achieve high capacity.

Advantages of Licensed Spectrum

Licensed Spectrum ensures that links can operate without interference from other links within a region – the frequencies are allocated centrally by national government regulators.  The 11GHz band is normally regulated by national governments for long distance links.  Frequency allocations may be narrower than the 112MHz channels shown here.  The FOR3 radio can be configured to operate within whatever channel assignments are offered,with channel widths and centre frequencies set under software control.  Typical channel widths for lower frequency bands are 14MHz, 20MHz, 28Mhz, 30MHz, 40MHz, 56MHz.

Zero-Footprint Solution

CableFree FOR3 is a Full Outdoor Radio for Zero-Footprint deployment, eliminating requirement for indoor locations or rack space. The radio is typically mounted on roof-top or tower location with antenna, with Power-over-Ethernet (PoE) connection to the radio using a single Cat5/e/6 cable. An optional SFP optical fibre interface is available for sites where long cable runs or electrical isolation to the radio is required.

Fully Shipping and Available

The CableFree FOR3 is fully shipping and available in all bands listed from 2 to 42GHz.

Microwave Rain Fade Planning ITU-R P.837-6

RECOMMENDATION ITU-R P.837-6

ITU-R P.837-6 P.0837-01  – Characteristics of precipitation for propagation modelling Radiowave propagation for Terrestrial Microwave Links and Radio Links for Point to Point (P2P, PTP) and Point to Multipoint (P2MP, PTMP) deployments.

Calculations can be made for Link Availability (%) for all frequency bands, to take into account link budgets, transmit power, receive sensitivity, antenna gain, target availability and other factors.  Typical Link Availability Targets are 99.99%, 99.999% and higher.

Recommendation ITU-R P.837 contains maps of meteorological parameters that have been obtained using the European Centre for Medium-Range Weather Forecast (ECMWF) ERA-40 re-analysis database, which are recommended for the prediction of rainfall rate statistics with a 1-min integration time, when local measurements are missing.
Rainfall rate statistics with a 1-min integration time are required for the prediction of rain attenuation in terrestrial and satellite links. Data of long-term measurements of rainfall rate may be available from local sources, but only with higher integration times. This Recommendation provides a method for the conversion of rainfall rate statistics with a higher integration time to rainfall rate statistics with a 1-min integration time.
