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, UltraLinkT-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. UltraLinkT-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. Furthermore, "zero-touch" configuration, through an integrated Bluetooth interface, minimizes its rollout time and safeguards against deployment errors.
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 256-QAM modulation) with bandwidth acceleration in a 1,500 MHz-wide channel. High spectral efficiency enables the use of narrower channels, which incur reduced license fees in countries where fees are applicable. Narrower channels also increase the number of available channel options, which allow for denser link deployments through the reduction of frequency reuse and facilitation of planning for interference management and mitigation.
UltraLink™-GX80 is based on a new generation of RF transceiver technology that provides high transmit power and receiver sensitivity. Offering system gain over 100 dB (without antenna) and over 200 dB with antennas, it pushes the range capability of E-Band radios to new highs. UltraLink™'s fast 7-level hitless adaptive modulation and coding can provide seamless system gain and capacity trade-off to enable highest capacity for most of the time and continuous link operation under adverse propagation conditions. Additionally, UltraLink™-GX80 can seamlessly be combined with OmniBAS™ OSDR microwave (6 GHz to 42GHz) radios exploiting advanced RLA functionality to increase link capacity and enhance reach / availability.
The same 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, 1 x GbE plus 2 x 1/10GbE-port 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 from packet-based encapsulation over Ethernet to the next generation standards in the future.
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, policing and shaping are applied to the incoming / outgoing service flows, allowing the definition and conformance of services to the desired characteristics.
Being an advanced packet radio, which is designed for mobile network transport applications, UltraLinkT-GX80 supports a full range a packet synchronization methods. Its Ethernet interfaces support standards-based Synchronous Ethernet (SyncE) frequency synchronization distribution, as well as, the associated ESMC signalling channel. Furthermore, Precision Timing Protocol (IEEE 1588v2) Transparent Clock and Boundary Clock functionality is supported in hardware for the delivery of frequency and phase synchronization deemed necessary in locations where GPS / GLONASS signals are hard to reach (such as sheltered / covered / street-level deployments).
UltraLink™-GX80 is a small form factor, lightweight, all-outdoor system. As such, it enables zero-footprint, minimum support infrastructure deployments. Links are easily deployed with its small form-factor ODU (290 mm x 246 mm x 80 mm), which weighs no more than 4.5 kg, thus 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 its "zero-touch" configuration and service provisioning feature, which is achieved through an integrated Bluetooth interface by employing a standard Android tablet.
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:
