Introduction - Nera Evolution Series Technical Description

1.

INTRODUCTION

The first chapter in this document contains information about the Evolution Series in general. Chapter
two and onwards cover the Evolution Series - XPAND specifically.
The Nera Evolution Series microwave radio dramatically changes the operations for wireless transmission
network owners. With a common platform architecture, which is fully software configurable;
transmission capacity, system configurations and transmission protocols can be changed to adapt to future
needs. Evolution Series dramatically reduces the cost of ownership. With significantly reduced number of
parts and high 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.
Network operators can easily future proof the network as the microwave radio can easily adapt to the
evolution of the transmission network. Growing traffic and the convergence of network technologies
causes changing requirements, such as capacity upgrades, change of transmission systems between PDH,
SDH/SONET and pure Ethernet; all this is simply implemented by software configuration change and
change of interface modules. The available interfaces range from E1, T1, E3, DS3 STM-1/OC-3, STM-
4/OC12 to 10/100BASE-TX and Gigabit Ethernet.
The Evolution Series product can be configured to work in three different modes. Payload capacity is also
configurable and is selected by SW licences. Changes and upgrades can be done by the user without HW
changes to the basic platform.
