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

RAy – Microwave Link

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)
RAy Microwave Link – © RACOM s.r.o.10
Implementation Notes

GTtransmitting antenna gain (dBi)
GRreceiving antenna gain (dBi)
FSL free space loss (dB)
PRmust be:
PR>PS
Where:
PSreceiver sensitivity (dBm)
The receiver’s sensitivity defines the minimum level of the received signal at which the receiver is able
to process the received signal without losses or affecting the transmitted data (for BER better then
10-6).
2.1.3. Fade margin
Determining sufficient fade margin is the most important step in microwave link design. If the margin
is too small, the link will be unstable – as a result, sufficient availability of the link or quality of the
provided services cannot be guaranteed. On the other hand, unnecessarily large margin makes the
link more expensive (higher performance, larger and more expensive antennas) and increases the
cost of creating the microwave link.
The following paragraphs describe the two most significant types of attenuation – rain and multipath
attenuation, which are the most frequent along with free space loss. Mutual relation between rain and
multipath attenuation rules out the possibility that the link could be affected by both types of attenuation
at the same time – these types of attenuation do not add up. To determine the fade margin it is ne-
cessary to calculate both rain and multipath attenuation. The larger of the two types of attenuation de-
termines the value of fade margin. In areas with high precipitation, rain attenuation can be expected
to be more prominent. By contrast, links located in drier climates and little inclination, will suffer more
from multipath attenuation.
2.1.4. Rain attenuation
FSL is not the only attenuation that influences the emitted signal. For frequencies of about 10 GHz rain
attenuation starts to become increasingly effective. Precipitation is not identical in all areas which is
why ITU released a recommendation Rec. ITU-R PN.837-1 for splitting the world into 15 regions ac-
cording to precipitation intensity see Fig. 2.1, for more detail Appendix B, Rain Zone Map. In the areas
with higher precipitation greater rain attenuation must be expected and a greater signal fade margin
must be established, see the calculation of link availability.
The following properties are inherent to rain attenuation:
• It increases exponentially with rain intensity
• It becomes significantly larger as the distance travelled increases (>10 Km)
• Horizontal polarization causes greater rain attenuation than vertical polarization
• Rain outage increases dramatically with frequency and path length

Rain attenuation can be calculated using ITU-R outage model, which consists of the following:
Obtain the rain rate R0.01 exceeded for 0.01 per cent of the time (with an integration time of 1 min).
R0.01 values are defined for 15 rain zones and different time percentages and they are given in ITU-R

Compute specific attenuation γR(dB/km) for the frequency, polarization, specific rain rate using ITU-R

Fig. 2.2 shows that rain attenuation is greater for horizontal polarization. In regions with higher precip-
itation the difference in attenuation is more marked. The microwave links RAy17 and RAy24 uses both
polarizations, hence the need to consider worse of the two, i.e. horizontal polarization. When ACM is
13© RACOM s.r.o. – RAy Microwave Link
Implementation Notes

active we recommend using horizontal polarization on the direction with lower data traffic (typically up-
link).
2.1.5. Multipath fading
Multipath fading is another dominant fading mechanism. A reflected wave causes a phenomenon known
as multipath, meaning that the radio signal can travel multiple paths to reach the receiver. Typically,
multipath occurs when a reflected wave reaches the receiver at the same time in opposite phase as
the direct wave that travels in a straight line from the transmitter.
Multipath propagation gives rise to two kinds of signal degrading effects, i.e., flat fading and frequency
selective fading. Flat fading is a reduction in input signal level where all frequencies in the channel of
interest are equally affected and is dependent on path length, frequency, and path inclination. In addition,
it is strongly dependent on the geoclimatic factor K.
To calculate the probability of outage due to multipath propagation of microwave links ITU-R probability
model can be used which describes a single frequency (or narrowband) fading distribution suitable for
large fade depths A in the average worst month in any part of the world (based on ITU-R P.530-14)
and for detailed link design is given as follows [1]:
P0=Kd3.4(1+|εP|)-1.03f0.8×100.00067hL-A/10
where:
dlink distance (km)
ffrequency (GHz)
hLaltitude of lower antenna (m)
Afade depth (dB)
K is geoclimatic factor and can be obtained from:
K= 10-4.6-0.0027dN1
The term dN1 is provided on a 1.5° grid in latitude and longitude in ITU-R Recommendation P.453.
The data are available in a tabular format and are available from the Radiocommunication Bureau
(BR). E.g. in Central Europe the values dN1 range from -242 to -362.
From the antenna heights heand hr(meters above sea level), calculate the magnitude of the path in-
clination │εP│ (mrad) using the following expression:

2.1.6. Fresnel zones calculation
The position of obstacles between points of the bridge can significantly influence the quality of the mi-
crowave link. The radio signal doesn't only radiate along the line of sight, but also in the area around
it, i.e. in the so-called 1st Fresnel zone. Within this zone 90 % of the energy is transmitted between the
transmitter and receiver antenna. This space has the shape of an ellipsoid. If it is disturbed the link has
worse transmission properties and a higher quality antenna is required. For this reason the position of
the antenna can be just as important as its height above ground. 60 % of the 1st Fresnel zone is con-
sidered as the most important.

Fig. 2.6: Fresnel zone
The general equation for calculating the first Fresnel zone radius at any point P in between the endpoints
of the link is the following:
Where:
F1first Fresnel Zone radius in metres
d1distance of P from one end in metres
d2The distance of P from the other end in metres
λ wavelength of the transmitted signal in metres
The cross sectional radius of each Fresnel zone is the highest in the center of link, shrinking to a point
at the antenna on each end. For practical applications, it is often useful to know the maximum radius
of the first Fresnel zone. From the above formula calculation of the first Fresnel zone can be simplified
to:
where:

• First antenna height above sea level: 295 m
• Second antenna height above sea level: 320 m
• Location: Central Europe (rain zone H, refraction gradient dN1= −300)
Transmission requirements:
• Required data rate: >160 Mbps
• Required availability: 99.99 %
RAy parameters:
• 17 GHz
RAy Microwave Link – © RACOM s.r.o.16

• 161 Mbps -> Modulation 16QAM; BW=56 MHz; PS(BER 10-6)= −79 dBm
• Tx power +5 dBm (max. Tx power)
• Antenna gain:
○ 30 cm ... 32.2 dBi
○ 60 cm ... 37.8 dBi
○ 99 cm ... 42 dBi
Step 1 - Free space loss calculation
FSL = 32.44 + 20log f+ 20log D= 32.44 + 20log17.2·103+ 20log4 = 129.1 dB
Step 2 - Rain attenuation
For 99.99% availability in rain zone B the rain rate is R0.01=32 (see Fig. 2.1)
For f=17 GHz kh=0.06146; αh=1.0949; kv=0.06797; αv=1.0137
Vertical polarization:
γR0.01 = kv.Rαv0.01 = 0.07 · 321.01 = 2.32 dB/km => for 4km distance 9.3 dB
Horizontal polarization:
γR0.01 = kh.Rαh0.01 = 0.06 · 321.09 = 2.62 dB/km => for 4km distance 10.5 dB
Step 3 - Attenuation due to multipath propagation
We have to find required fade margin for reliability of the link 99.99 percent.
Path inclination:
The percentage of time that fade depth A (dB) is exceeded in the average worst month is calculated
as:
P0=Kd3.4(1+|εP|)-1.03f0.8×100.00067hL-A/10
P0=10-4.6-0.0027×(-300)×43.4(1+|6.25|)-1.0317.20.8×100.032×10-0.00067×295-A/10
P0=0.022871×10-0.19765-A/10
For reliability 99.99% is P0=0.01 we get exponential function for A:
A= -0.19765 - 10log(0.01/0.022871) = 3.4 dB
The minimum fade margin required to suppress multipath fading on this link would be 4 dB.
Step 4 - Link budget calculation
Calculation in steps 2 and 3 determines the minimum fade margin required for stable link operation
as 11 dB (rain attenuation is dominant). If you use the maximum performance of antenna with dia-
meter of 30 cm, complete the radio formula as follows:
PR=PT+GT+GR−FSL = 5 + 32.2 + 32.2 − 129.1 = −59.7 dB
Fade margin:
A= |PS| − |PR| = 79 − 59.7 = 19.3 dB
The resulting fade margin is larger than the required 11 dB. Current legislation in the Czech Republic
allows maximum EIRP of +20, i.e. the sum of transmit power and antenna gain at the transmitter
can be 20 dB at the most. For 99cm antennas, TX power can be up to 20 - 42 = -22 dB, the resultant
equation is as follows:
17© RACOM s.r.o. – RAy Microwave Link
Implementation Notes

PR=PT+GT+GR−FSL = -22 + 42 + 42 − 129.1 = −67.1 dB
Fade margin:
A= |PS| − |PR| = 79 − 67.1 = 11.9 dB
Fade margin is now only 12 dB which corresponds to link availability > 99.99% of the time in a year.
Technical literature often gives the minimum fade margin of 20 dB. For very long links (more than
10 km) fade margin will, indeed, be approximately 20 dB. For shorter links, however, such large
margin is not necessary. It is helpful to first conduct the calculation above to receive an idea of the
attenuation affecting the link.
The result
To achieve the required transmission capacity and link availability for link distance of 4 km, transmit
power -22 dBm and 99 cm antennas were selected for both sides of the link.

Implementation Notes

3. Product
The RAy microwave links are designed for data transmissions in both licensed and unlicensed ISM
bands. They work as a point-to-point link in full duplex regime with transfer speed up to 360 Mbps.
Bandwidth is selectable from 1.75 up to 56 MHz. Modulation can be fixed or adaptive and can be ad-
justed from QPSK to 256QAM.

The link is formed by two FOD (Full Outdoor) stations. In the case of links operating in the ISM bands
(RAy17, RAy24), both stations have identical hardware. In the case of links operating in the licensed
bands, one unit is transmitting in the Lower and receiving in the Upper part of the band. The other unit
is operating vice versa.
RAy links are used with external parabolic antennas. Parabolic antennas from different producers are
available.
Cross polarization - valid only for links operating in the ISM bands (RAy17, RAy24):
One side of the link uses one polarization for transmission (e.g. horizontal) and the opposite polarity
for receiving (e.g. vertical). The other side of the link is turned by 90°. It therefore transmits and receives
using opposite polarizations with respect to the other side.

3.2. Installation
The antenna is attached to the mast using a holder adjustable in two planes. The RAy unit is then
mounted on the antenna. There are two possible mounting positions – for horizontal and vertical polar-
ization. Installation and adjustment of the holder is described in Chapter Antenna mounting.
