Mobile and fixed broadband network operators, WISPs / ISPs and other non-telco organizations (enterprises, utilities, industrial and governmental organizations), are in need of cost-effective high-capacity transport systems that are easy to deploy and operate. When optical fiber connectivity is not available, easy to deploy or cost-efficient, multi-gigabit transport E-Band radio systems are a reliable alternative solution addressing the needs of today's data-driven networks.
Access broadband networks, both Mobile and Fixed, are undergoing a continuous transformation in terms of technology and architecture towards supporting end user Gigabit rates. In particular, Mobile network capacity and density increase dramatically, while different architectural RAN options, such as Centralized RAN, emerge as a means of increasing the network capacity and efficiency via coordination and resource virtualization and pooling. Mobile broadband network operators need to cope with higher capacity, multi-generational technology (GSM, HSPA/HSPA+, LTE, LTE-A, 5G) Base Stations deployed in an ever-increasing density macro-cell layer and in an ultra-dense small-cell layer.
UltraLink™-FX80 and the newer addition UltraLink™-FX80 Compact Node (CN) are all-outdoor PtP radios operating in the entire E-Band spectrum (71-76 GHz and 81-86 GHz). Offering leading RF system gain, rich Carrier Ethernet networking functionality, advanced frequency/phase synchronization features and low latency they ideally satisfy the service requirements for X-haul/transport applications up to 3 Gbit/s in both Mobile or Fixed broadband access networks.
UltraLink™-FX80 can be combined with Intracom Telecom's OmniBAS™ MW packet radio line (comprising flexible aggregation IDUs) to provide high capacity radio links with enhanced range and/or availability. Typical applications for UltraLink™-FX80 and UltraLink™-FX80 CN include: Mobile RAN backhaul, midhaul, fronthaul in urban and suburban areas, Fixed access network backhaul, enterprise/university campus building connectivity, shipping port area communications systems, public service network connectivity, WiFi hotspot backhaul and fiber backup links to name a few.
UltraLink-FX80™ offers a number of high-value features, which are elaborated below:
The field-tested UltraLink™-FX80 / UltraLink™-FX80 CN incorporate a new generation of RF transceiver technology which, combined with INTRACOM TELECOM's top-of-the-line modem technology, provide high transmit power and receiver sensitivity. Offering system gain over 100 dB (without antenna), and over 200 dB with antennas, UltraLink™-FX80 / UltraLink™-FX80 CN radios push the range capability of E-Band radios to new highs. Furthermore, UltraLink™-FX80's hitless adaptive modulation features enable high link robustness and allow the deployment of high availability links with small form factor antennas that respect the city environment and minimize tower rental costs. Intelligent combination of state-of-the-art LDPC and Reed-Solomon FEC schemes maximizes sensitivity at a minimum cost to transport efficiency. Their fast 7/9-level Hitless Adaptive Modulation and Coding can provide 28/33dB (FX80/FX80CN) of system gain improvement to enable continuous link operation under adverse rain precipitation conditions.
UltraLink™-FX80's 3 Gbit/s capacity on a single radio link is achieved by combining an industry-high spectral efficiency (through 256-QAM modulation for UltraLink™-FX80 and through 512-QAM for UltraLink™-FX80 CN) with bandwidth acceleration in a 500 MHz-wide channel. High spectral efficiency enables the use of narrow channels, which can incur reduced license fees in countries where radio operation in the E-Band is charged. Especially, UltraLink™-FX80 CN supports channel sizes of 62.5 MHz and 125MHz (additionally to 250MHz at 500 MHz), enabling high capacity at minimum channel size/cost. In particular, 500 Mbit/s/ 1 Gbit/s/ 2 Gbit/s can be achieved at 62.5 / 125 / 250 MHz channel sizes respectively using 1024-QAM modulation.
Using narrower channels also increases the number of available channel options, which allows for denser link deployments through the reduction of frequency reuse and facilitation of planning for interference management and mitigation.
The same radio unit can be configured to operate in Ethernet Bridging or CPRI transport mode for providing CPRI fronthaul. UltraLink™-FX80 / UltraLink™-FX80 CN incorporate a fully-featured, 3 x GbE Provider Bridge (IEEE 802.1ad), which offers flexibility in delivering MEF standards-based Carrier Ethernet services over complex network topologies, such as tree or ring, deployed without the need for additional switching devices. This allows faster and easier deployments that are more manageable and cost-efficient.
Furthermore, UltraLink™-FX80 / UltraLink™-FX80 CN support a CPRI transmission mode (CPRI Options 2 and 3). When operating in this mode, UltraLink™-FX80 / UltraLink™-FX80 CN can support a native CPRI traffic stream and provide operators the cost-efficient fronthaul transport needed to extend the reach of their C-RAN network wherever fiber is not available and wherever fiber deployment is financially prohibitive.
Support of Ethernet Service OAM and Performance Monitoring based on IEEE 802.1ag / ITU-T Y.1731 and Ethernet Link OAM based on IEEE 802.1ah by UltraLink™-FX80/ UltraLink™-FX80 CN enables Carrier Ethernet network operators to monitor and troubleshoot their services by using standardized tools and techniques.
UltraLink™-FX80 / UltraLink™-FX80 CN offer per-service flow QoS treatment of the transported traffic based on L1, L2 and L3 classifiers. Strict Priority (SP), Weighted Round Robin (WRR), Weighted Fair Queuing (WFQ) and Hybrid SP+WRR/WFQ scheduling schemes are cleverly applied to eight CoS / queues to enable the most suitable prioritization treatment for management, control-plane traffic and critical service delivery for user-plane traffic. Ingress policing and egress shaping are applied to the incoming / outgoing service flows allowing the definition and conformance of services to the desired characteristics. Colour-aware WRED is applied as means to gracefully manage potential queue congestion. Furthermore, Hierarchical QoS is also supported to enable a more precise and fine-grained controlled of multiple traffic streams / services served by an interface.
Based on an advanced packet radio platform, which is designed to fully satisfy mobile network backhaul applications, UltraLink™-FX80 / UltraLink™-FX80 CN support a full range of packet synchronization methods. Gigabit Ethernet interfaces support Standards-based Synchronous Ethernet (SyncE) frequency synchronization distribution, as well as, the associated ESMC signaling channel. Furthermore, Precision Timing Protocol (IEEE 1588v2) Transparent Clock and Boundary Clock functionality (Profile ITU-T G.8275.1) is supported in hardware for the delivery of Frequency and Phase Synchronization especially needed in locations where Global Navigation Satellite Systems (GNSS) time signals are hard to reach or for synchronization backup reasons.
The Radio Link Quality Monitoring (RLQM) tool is functionality embedded in the UltraLink™ radio element. It monitors the propagation channel dynamics and identifies possible radio channel related problems. It helps determine link degradation causes such as: rain, pole structural instability, radio interference, etc. It allows to remotely and quickly identify and verify the cause of a link quality problem without on-site staff support presence or additional measurement equipment, improving the network manageability and availability by expediting the detection and resolution of a link quality problem. Thus, it increases the overall network quality and services availability and reduces the network operating costs and lost service revenues.
The Radio Link Quality Monitoring tool offers the following functionality:
The spectrum analyzer and frequency band auto-scanning features can further assist in the cause analysis, as well as, prove very useful at the link commissioning phase for the identification of interference from other active links. This feature can be combined with the appropriate uniMS™ add-on module to enable network wide monitoring of the radio quality conditions of the installed links.
UltraLink™-FX80 / UltraLink™-FX80 CN are compact, zero-footprint, all-outdoor system that requires minimal deployment space and can be adapted to suit many different types of installation locations. UltraLink™-FX80 CN ODUs, weigh no more than 2.7 kg and can be combined with a range of antenna types that suit different link ranges and applications. Flat antenna options minimize the overall size and visual impact of the deployment for relatively shorter links, while 30 cm and 60 cm parabolic antenna options are available for longer range links.
UltraLink™-FX80 / UltraLink™-FX80 CN come with high powering flexibility as they offer Direct DC, Direct AC or PoE options. In particular, direct AC power feed without external PoE or AC/DC converter devices enables more cost-effective, quicker deployments particularly at non-telco environments (residential, street-level etc).
