  • Page 9: Introduction

    MTBF Evolution Series ensures maximum uptime and low maintenance. The Evolution Series microwave radio is designed to transmit data rates from about 6 Mb/s to 600Mb/s, in the frequency bands from 5 GHz to 38 GHz. The configuration of capacity and modulation is software configurable, giving an optimal balance between system gain and spectral efficiency.
  • Page 10 Traffic Node with 4 radio directions, SNCP with Ring, Chain, Star or Mesh topology The Evolution Series is an integrated part of Nera’s wide product portfolio, from the leading microwave specialist. The product portfolio covers products for all type of professional wireless carrier systems.

  • Page 11: Features

    1.1. Features The Evolution Series microwave radio utilises the state-of-the-art technology to achieve low power consumption and high reliability. A high degree of RF circuit integration is achieved using Microwave Monolithic Integrated Circuits (MMIC’s). This, combined with a direct at RF modulation architecture, enables a broadband and compact ODU design.

  • Page 12: Network Applications

    1.2. Network Applications The Evolution Series microwave radio is ideally suited for a wide range of applications. Due to the flexibility in configurations, the choice of traffic interfaces and the capacity scalability, it can easily adapt to the specific requirements of a given network application. The flexibility and ease- of upgrade, future proof the investment, as the equipment can grow with the increasing traffic demand as well as easily adapt to other transmission technologies.
  • Page 13 MultiPoint radio access systems like WiMax. With a selectable capacity, ranging from about 6Mb/s to 600Mb/s, the Evolution Series radio can easily be deployed in small network as well as in larger constellations and networks with several sites linked together. The choice of pure TDM (E1/T1), Ethernet/Gigabit Ethernet, or 155Mb/s SDH/SONET, or a combination of TDM (E1/T1) with Ethernet/Gigabit Ethernet, makes the Evolution Series suitable for any FWA network installation.
  • Page 14 With choice of pure TDM (E1/T1/E3/DS3), Ethernet/Gigabit Ethernet, 155Mb/s SDH/SONET, or a combinations of TDM (E1/T1/E3/DS3) with Ethernet/Gigabit Ethernet, makes the Evolution Series suitable for most private networks, whether they are carrying legacy services or data only. Flexibility and simplicity, combined with a predictable reliability, proves for many network owners to be an unbeatable combination.
