• On your PC set up a similar address with the same mask, e.g. 192.168.169.180/24.
○To configure your PC’s address in Windows XP do the following: Start – Settings – Network
Connections:
Change properties of this connection – Internet Network Protocol (TCP/IP) – Properties – Use
the following IP address – input 192.168.169.180 and use the mask 255.255.255.0. Click OK
twice.
• Connect both RAy units to a PoE source and connect to a PC via PoE for configuration, see Fig.
Link Configuration.
• Input the address of the connected RAy unit into the address field of your internet browser (such
as Mozilla Firefox), e.g. 198.168.169.169. Login as admin with password admin.
•Status menu provides information on connection.
•Settings – Radio menu enables you to change the parameters of the radio and ethernet channel,
Settings – Service Access – Users menu lets you change login parameters.
• Continue as suggested by the Step-by-step Guide.

1. RAy – Microwave Link
RAy Microwave link RAy is designed as high-speed point-to-point wireless bridge for data transmission
under the latest requirements of modern wireless transmission equipment. It is built on a platform with
a modern component base.
Ray works with ethernet interface and can be used in backhaul networks as well as a last-mile termin-
al.The design of microwave link RAy reflects effort on meeting the strictest criteria ETSI standards,
particularly for durability against interference, high receiver sensitivity and high output power to achieve
maximum link distance. Native gigabit Ethernet interface is able to cope with full speed user data
throughput at low latency. High availability of the link (up to 99.999%) is able to be achieved with using
hitless Adaptive coding and modulation.
The link properties can be summarised as:
• High data throughput
• Spectrum effeciency
• Robustness
• Security - cofiguration via http, https, ssh
• User friendly interface, advanced diagnostics

2. Implementation Notes
2.1. Link calculation
Before a microwave link can be installed, an analysis and calculation of the microwave link must be
made first. The analysis should take place before the site survey itself to get a clear idea about the di-
mensions of the antennas. The analysis consists of the following steps:
• Free space loss calculation
• Link budget calculation
• Rain attenuation
• Multipath fading
• Fade margin
• Fresnel zones calculation
This chapter explains the individual steps and an example of link design is given at the end.
2.1.1. Free space loss calculation
As the electromagnetic waves travel through open space they are attenuated. This attenuation is de-
scribed as Free-space Loss. This loss depends on the distance travelled by signal and its frequency.
Longer distance means greater attenuation and higher frequency means greater attenuation. Free-
space loss can be calculated thus:
FSL = 32.44 + 20log f+ 20log D
Where:
FSL free-space loss (dB)
ffrequency of the emitted signal (MHz)
Dlength of the link (km)
2.1.2. Link budget calculation
To goal is to design a link so that the received signal is stronger than the receiver's sensitivity at the
required BER (typically 10-6). Since every radio signal in earth atmosphere is subject to fading, some
difference between received signal level under normal circumstances and receiver sensitivity is needed
to serve as a fade margin. The minimum value of fade margin can be calculated from the requirement
for link availability (e.g. 99.999% of the time). The required margin depends on the length of the link
as well as other factors such as rain attenuation, diffraction and multipath propagation.
If we ignore the additional loss along the path, the received signal strenght can be calculated using the
formula for signal propagation in free space as follows:
PR=PT+GT+GR-FSL
Where
PRreceived power level (dBm)
PTtransmitted power (dBm)
