MINI-LINK 6365MINI-LINK 6000The increasing complexity of today’s and future networks requires flexible and well-integrated microwave nodes. Building an efficient microwave backhaul network with end-to-end performance in mind, requires high node capacity, compact and modular building practice, advanced packet functionality and features that are aligned and backward-compatible across different network nodes. The microwave nodes also need to be capable of handling single hops as well as advanced hub sites for larger networks. By combining different units in the MINI-LINK 6000 portfolio, all network scenarios are supported with superior performance and lowest possible cost of ownership.Ericsson is the market leader in microwave transmission and has over 40 years of microwave experience with more than 4 million radio units delivered to over 180 countries. High capacities in a compact formatThe MINI LINK 6365 is to be used in split systems together with MINI-LINK 6000 nodes. The radio connects to the node via a single coaxial cable. It comes in all traditional frequency bands 6-42 GHz and is future proof with carrier aggregation and 16k QAM support. It supports 2.5 Gbps in a very compact format. The high output power caters for the need of high capacities and high availability, providing superior network performance.World’s smallest high power radioMINI-LINK 6365 builds on the strengths of MINI-LINK 6363 and RAU2 X, the world´s most widely deployed microwave radio. MINI-LINK 6365 has the same small footprint as MINI-LINK 6363. This enables easier and faster installations as well as less wind load on towers.Ericsson ABSE-417 56 Göteborg, Sweden 287 01-FGC 101 3676 Rev B© Ericsson AB 2020Carrier aggregation – 2x 112 MHz and 2.5 GbpsMINI-LINK 6365 is a 1T1R radio supporting carrier aggregation. It can transmit two channels, up to 2x 112 MHz, in the same polarization,doubling the capacity vs MINI-LINK 6363. The channels can be adjacent or non-adjacent, for maximum utilization of available spectrum. 2x 112 MHz carrier aggregation provides a capacity of 2.5 Gbps, to support the ever-growing need for higher capacities. Carrier aggregation is available as a SW license, making it possible to double the capacity without changing the hardware.Highest modulation scheme – 16k QAMThe radio supports the highest modulation scheme in the market 16k QAM, increasing capacity by 15% vs 4k QAM and 25% vs 2k QAM.Superior system gainMINI-LINK 6365, in combination with MINI-LINK 6000 nodes, has the highest system gain in the split mount market, maintained also for higher modulations. The high system gain is crucial to enable the use of the high modulations and carrier aggregation. A high system gain means more capacity, higher availability and smaller antennas. High output power is available as a SW license, which makes it possible to step up in modulation and capacity when needed.Modular antennas and flat panel antennasMINI-LINK 6365 uses the same antenna portfolio as MINI-LINK 6363. The 0.3-1.8 m reflector antennas are modular, making them upgradeable from single to dual polarization without the need for realignment. This is done by replacing the interface only. With high focus on visual appearance and minimized size, Ericsson has created the world's smallest outdoor unit (radio+antenna) in traditional bands with a range of flat panel antennas. Since antenna performance is key to secure network performance, the flat panel antennas are guaranteed to be ETSI class 3 compliant and typically close to ETSI class 4 compliance.Scalable multi-carrier solutions, with hardware protectionA scalable upgrade path from single to multi-carrier is supported:1+0 → 2+0 → 4+0 → 8+0. Investments can be taken as the need for more capacity arises, following a pay as you grow approach. With MINI-LINK 6365, a single type of radio be can be used throughout the network. This simplifies network rollout and reduces operation costs. Transceivers in separate housings also gives better hardware protection and ensures no downtime during replacement of faulty hardware.Backward compatibilityMINI-LINK 6365 is hop compatible with MINI-LINK 6363 and MINI-LINK RAU2 X, in single carrier mode. If a radio unit needs to be upgraded, the antenna and radio cable can be reused.Ingress protectionThe radio unit can be installed in very harsh environments as it fulfills IP66 protection against dust and water.ATEX certifiedWith ATEX certification MINI-LINK 6365 can be used in potentially explosive atmospheres (Zone 2).Technical Specification MINI-LINK 6365RADIO LINKCapacity: 2.5 GbpsChannel: 7 – 112 MHzCarrier aggregation: 2x 28 – 2x 112 MHzModulation:4 QAM – 16k QAMTX power: -10 to +30 dBmFREQUENCIES 6 – 42 GHzWEIGHT 2.5 kg / 5.5 lbsDIMENSIONS (H × W × D) 179 × 197 × 79 mm (2.8 l) 7.0 × 7.8 × 3.1 in (170 in 3)POWER SUPPLY +57 VDCPOWER CONSUMPTION 24 WREFLECTOR ANTENNAS 0.2 – 3.7 m / 9 in – 12 ft HP and HPX SHP and SHPXFLAT PANEL ANTENNAS 0.1 m SHP28 – 42 GHz, 30 – 34 dBiINTEGRATEDCONFIGURATIONS 1+0, 1+1, 2+0, 4+0 and 8+0INTERFACES Coaxial (modem)Waveguide (antenna) Alignment portSTANDARDS AND RECOMMENDATIONS ETSI, ECC, FCC, IC, IEC, ITU, ATEXENVIRONMENTAL SPECIFICATIONS -45 to +60 °C / -49 to +140 °F IP66NODES MINI-LINK 6000NETWORK MANAGEMENTServiceOn Element Manager IP Transport NMSEricsson Network Manager。
