CableFree Diamond Microwave Links: Full Outdoor Dual-Core 4+0 XPIC Radio

CableFree Diamond is a new Microwave dual-core platform, for high capacity, modern IP microwave radio links offering up to 5Gbps Full Duplex net throughput for diverse applications including 4G & 5G LTE Backhaul, corporate networks, CCTV, Safe Cities and Wireless ISP backbones.

Unique in the wireless industry, CableFree Diamond is available in both Licensed (4 to 42GHz) and Unlicensed (17 & 24GHz) bands, allowing for lower Total-Cost-of-Ownership.  This dual-core radio features two complete modems and radios, including XPIC 4+0 modes for ultra high capacity

CableFree Diamond 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+ 10Gbps optical fibre interface is available for sites where long cable runs or electrical isolation to the radio is required.

Accessories for CableFree Radios

Please use Surge Suppression when installing CableFree Radios where appropriate.  Ethernet (POE) Surge Arresters are available for various different types of installations.  Always ensure safety of personnel as well as equipment when installing CableFree Wireless solutions.  If in doubt, consult a qualified electrician.

Advanced Microwave Technology and Features

Low Power Consumption supports “Green” initiatives and use with alternative off-grid power sources such as Solar+Battery for remote mountain-top repeater sites where no AC power is available. CableFree Diamond features industry-leading specifications including high capacity up to 5Gbps, advanced modulation up to 4096QAM for high spectral efficiency, full support for ETSI and ANSI channel plans from 10MHz up to 112+112MHz.
Automatic Coding and Modulation (ACM) dynamically adjusts the link capacity in adverse conditions, enabling operators to offer extended distances, higher availability, and utilise smaller antennas to fit within size, aesthetic and budget constraints. High output power up to 25dBm or more ensures best possible link margins for long range links.
Backhaul transmission for 4G & 5G LTE networks is enabled with Sync-E and Quality of Service (QoS) features
All CableFree Microwave links are easy to install and fully manageable with easy-to-use Web NMS as well as network-wide SNMP platforms.
Aggregation of 2+0, 4+0 or higher combinations channels together to achieve multi-Gigabit capacities of 5Gbps and beyond.  CableFree Diamond is a Rugged, full-outdoor design suited long-term operation in harsh climates.

Integrated XPIC: Cross Polar Interference Cancellation

CableFree Diamond integrates two complete radio cores with the XPIC technology: this allows simultaneous transmission of both radios on each of Horizontal and Vertical polarities in the same frequency band and channel without interference.  This doubles the capacity and spectral efficiency compared to a non-XPIC radio.  By integrating XPIC into the radio, RF losses are far lower than traditional discrete solutions that require two separate Microwave ODUs and a coupler.  Integrated XPIC ensures higher signal fidelity and better link margins, which translate to longer range and higher availability.

Licensed and Unlicensed Microwave Links

Unique to CableFree, the Diamond links are available in licensed bands (3.5 to 42GHz) as well as Unlicensed band (5GHz, 17GHz, 24GHz) versions.  This flexibility enables operators to mix/match or upgrade sections of their networks, and to evolve as time and customer pressures for capacity and coverage increase.
Note: Not all bands are Unlicensed in all countries.  Local regulation will apply.  Check with your local Telecom Regulator to be sure.

4+0 Microwave Configurations

CableFree Microwave Links can be configured in 4+0 Configuration using 112+112MHz for Ultra High Capacity applications and increased Resilience: with no Single Point for Failure in active transmission path, the system availability is dramatically increased.  4+0 configuration enables Diamond system capacity up to 5Gbps full duplex for Multi-Gigabit capacities in modern networks.

Higher speed configurations are possible with Dual 2+0 and 4+0 microwave link configurations if required to enable future network growth requirements.


CableFree Microwave links are used in a wide range of applications including 4G/LTE Backhaul, Wireless ISPs, CCTV for Safe Cities, Police, Law Enforcement, Fire, Port and Border Security ANPR applications.
CableFree Diamond can also be used as part of CableFree UNITY solutions along with MMW and other technologies to increase range, throughput and availability.
Microwave is an attractive alternative to fixed copper or fibre networks and leased lines. Wireless links can be installed at a tiny fraction of the cost of trenched or leased fibre, providing a rapid Return On Investment (ROI). Links can be rapidly deployed in a single day, rather than waiting weeks or months for fibre circuits. Microwave provides an ideal alternative resilient path to mission critical cabled links where outage could cause severe loss-of-revenue or operational disruption.
