In the process of adapting their mobile network capabilities to the exponentially-increasing capacity and service-type diversity, mobile network operators are continuously upgrading their Radio Access Network (RAN) and core network infrastructure. The evolution of the current distributed 2G / 3G /4G RAN architectures to the denser and Centralized (C-RAN) 4G+ / 5G architectures, will dramatically increase the backhaul and fronthaul link capacity and density.
Wireless technologies, which offer unique deployment flexibility, speed and TCO benefits, have evolved to provide performance and functionality characteristics that satisfy the transport requirements of the mobile networks, now and in the future. E-Band radio technology, which can currently offer multi-Gigabit capacities with minimal hardware configuration (1+0), has already established itself as a wireless technology that can already meet the needs of 4G+/5G wireless backhaul and fronthaul applications.
UltraLink™-GX80 is a next-generation, all-outdoor, E-Band (71-76 / 81-86 GHz) radio that is ideally suited for use in demanding transport applications requiring fiber-like capacity and extended range. It offers both Ethernet and CPRI functionality on the same unit, so that it can be used both in backhaul and fronthaul applications.
Offering ultra-high capacity, low latency and support for all packet synchronization options, it fully satisfies the rigorous backhaul requirements of 4G+ and future 5G mobile networks.
When operating in CPRI mode, UltraLink™-GX80 can support up to three CPRI traffic streams and provide operators the cost-efficient fronthaul transport needed to build and extend the reach of their C-RAN networks. UltraLink™-GX80's small size and intelligent design allows it to be easily and quickly deployed on rooftops or telecommunication towers, taking-up minimal space, and minimising power consumption per Gigabit.
UltraLink™-GX80 offers a number of highly-valued features, which are elaborated below:
UltraLink™-GX80 is offering 10 Gbit/s capacity on a single 1+0 radio link achieved by combining an industry-high spectral efficiency using up to 512-QAM modulation with bandwidth acceleration in a 1,500 MHz-wide channel and up to 256QAM for a 2000MHz-wide channel. Furthermore, 1024-QAM is supported for channel sizes from 125 to 500MHz and 512QAM is supported for channel sizes from 750 to 1500MHz maximizing the spectral efficiency of the radio, enabling the use of smaller frequency channels to deliver a particular capacity. Use of smaller channels increases the number of available channel options in dense deployment planning scenarios, reducing frequency reuse and facilitating interference management and mitigation. Use of smaller channels also can also incur reduced license fees in countries where such E-Band channel pricing is applicable.
UltraLink™-GX80 is based on a new generation of RF transceiver technology that provides high transmit power and receiver sensitivity. Furthermore, it benefits from the state-of-the-art INTRACM TELECOM's modem technology. Offering system gain over 100 dB (without antenna) and over 200 dB with antennas, it pushes the range/availability capability of E-Band radios to new highs. At 10Gbps throughput the radio offers leading market system gain. At 10Gbps @ 256QAM/1500Mhz the gain exceeds 64dB, while for 128QAM/2000MHz the system gain exceeds 67dB without antenna in both cases. The system gain advantage of UltraLink-GX80 is present also at other channel sizes and modulation formats supported. UltraLink™-GX80's fast up to 9-level hitless adaptive modulation and coding can provide seamless system gain and capacity trade-off to enable highest capacity for most of the link operational time and continuous link operation under adverse propagation conditions. Additionally, UltraLink™-GX80 can be paired with OmniBAS™ microwave (6 GHz to 38GHz) radios exploiting advanced RLA functionality to further enhance the combined logical link's reach / availability.
The same UltraLink™-GX80 radio unit can be configured to operate in Ethernet Bridging or CPRI transport mode for providing transparent CPRI fronthaul. UltraLink™-GX80 incorporates a fully-featured, 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™-GX80 supports a CPRI transmission mode up to CPRI Option 7. When operating in this mode, UltraLink™-GX80 can support up to three CPRI traffic streams 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.
Importantly, UltraLink™-GX80 software-upgradeability offers the flexibility to support the evolution of fronthaul protocols to the next generation standards eCPRI / O-RAN over Ethernet in the future. Support Nenxt Generation fronthaul protocols, the evolution of CPRI, is within the scope of UltraLink™-GX80 as it natively supports the Ethernet traffic requirements based on the IEEE 802.1CM profile A, as well as, highly precise synchronization methods.
Support of service OAM, based on the IEEE 802.1ag and Y.1731 standards, and Link OAM, based on the IEEE 802.3ah standard, means that UltraLink™-GX80 is capable to offer carrier-grade Ethernet OAM features, enabling operators to provide manageable L2 end-to-end services to their customers.
UltraLink™-GX80 offers per-service 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 and control plane traffic, while supporting revenue-generating service differentiation and assured critical service delivery for user plane traffic. Color-aware WRED is applied as means to gracefully manage potential queue congestion. Furthermore, ingress policing and egress shaping are applied to the incoming / outgoing service flows, allowing the definition and conformance of services to the desired characteristics. Hierarchical QoS is applied at the egress on a per queue and service level allowing the more effective, fine-grained QoS treatment of traffic.
Being an advanced packet radio, which is designed for mobile network transport applications, UltraLink™-GX80 supports a full range a packet frequency and phase/time synchronization methods. Its 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 (T-BC) / (ITU-T 8275.1 profile) functionality is supported for the delivery of frequency and phase synchronization deemed necessary in case GPS / GLONASS signals become unavailable
The Radio Link Quality Monitoring (RLQM) tool is functionality embedded in the UltraLink™-GX80 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™-GX80 is a compact, all-outdoor system. As such, it enables zero-footprint, minimum support infrastructure deployments. Links are easily deployed minimizing the overall cost for the supporting site. Apart from all the usual methods (by Ethernet cable connection), UltraLink™-GX80 also offers deployment expediency by the "zero-touch" configuration and service provisioning feature, minimizing rollout time and safeguarding against setup errors.
Large organizations with multi-building connectivity needs such as corporations in the manufacturing sector or services / logistics sector, utilities & mining industries, public sector & governmental, higher education & health institutions, can deploy UltraLink™-GX80 to:
