MARCONI Long Haul

MARCONI Long Haul is breaking capacity barriers previously completely out of reach for microwave systems. High availability in performance is extra useful for long distances and situations with difficult terrain & catastrophic locations.

MARCONI LH is ideal for any application where fiber is not an option due to technical or economical reasons. It is used e.g. for ring closure of metro and core rings, and for access to Point of presence. It is extra useful in situations with difficult terrain, lack of right of way and when a short implementation time is required. The market leading reliability is based upon MARCONI LH’s highly robust system architecture, with no single point of failure. It offers multiple protection mechanisms such as N+1 for radio protection and MSP 1+1 for protection of optical interfaces.

It is also often used as a back-up solution for a fiber connection. The traditional application where MARCONI LH can be found is within Telecom Networks where it is used in a variety of areas. TV Broadcasting backhaul is another application where MARCONI LH is successfully being used by our customers. Ericsson offers a complete solution for Digital Terrestrial TV distribution.

MARCONI is also used in Communication Networks and also successfully being used for offshore oil exploration operations to control data, internal communications and video surveillance. Utility and media companies, as well as defense and transportation industries are the main users. It is a high performance radio link with long hop lengths due to high system gain and advanced diversity receiver. Typical hop lengths range from 5 –120 km; extreme hops with distances over 170 km are also in service, particularly useful for Oil & Gas operators.

All Long Haul frequency bands, from 4 to 13 GHz, are available. Ethernet is available via an Ericsson verified solution and a common management system. MARCONI LH’s best in class spectrum efficiency enables operators to transmit very high capacity in a small number of frequency channels. Up to 20 STM-1 can be sent over one antenna using only 10 frequency channels with CCDP (Co-Channel Dual Polarization).




MARCONI LH has no restriction in channel arrangement; each immediate channel neighbour can be used. Marconi LH’s different modulation schemes with multilevel coding optimize the hop length for available frequency bandwidth and in combination with a highly linear transmitter minimize the pollution of adjacent channels. This results in optimal usage of the frequency space and a denser network.

MARCONI LH is a trunk radio that provides cost effective wireless transmission of multiple STM-1 signals and Ethernet over medium and long distances in the trunk and metro area of SDH and packet networks. It offers rapid rollout of transmission capacity and with integrated network management Marconi LH is an economical alternative and complement to fiber transmission. Extra useful in situations with difficult terrain & catastrophic locations.
