The LoRa ioT Station owns a GPS and a GSM integrated solutions. Those both technologies need to install the
product in an open environment to get acceptable performances.
Depending on the LoRa IoT Station version, different WAN configuration can be used:
- LoRa IoT Station 868: EGSM900/DCS1800/UMTS900/UMTS2100
- LoRa IoT Station 915: GSM850/PCS1900/UMTS850/UMTS1900

Position of the universal antenna support vs. the enclosure
The universal antenna support as described on Figure 14 is intended for the LoRa antenna.
To optimize the colocation between the internal GSM antenna and the external LoRa antenna, a distance of
20 cm is required between both radiated parts.
Therefore, when possible we strongly recommend dissociating the universal antenna support away from the
enclosure support. This is the best way to guarantee the 20 cm min distance between GSM antenna and LoRa
antenna.
When the dissociation is not possible, the LoRa antenna must be placed on the opposite side of the GSM
antenna as described on Figure 15.

Key parameters to optimise the radio performance
Height of the site
A key point to have an optimized LoRa IoT reception is the height of installation site and moreover the height
of the LoRa antenna. The LoRa IoT Station must be installed as high as possible to have the better reception.
The figures below shows the RSSI of the signal vs. the distance to the end point vs. the height of the Lora IoT
station (4m, 8m, 12m and 30m). Two uses cases are presented: one for a small city configuration (urban
area) and one for countryside area.
The propagation model used is based on Hata model.
The frequency is 868MHz in this case but performance and conclusions at 915MHz would be almost identical.
The RSSI is the received signal by the LoRa IoT Station.
The end point EIRP is assumed to be 25mW.
The height of the end point is 1m.

What is noticeable is that the coverage distance at a fixed RSSI is doubled depending on the height of the
antenna.
7.3.7.2
Propagation model vs area type
Predicting the RSSI and more generally the coverage of the LoRa IoT Station depends on many factors. The
propagation channel must be well defined and known to have an efficient prediction.
Radio coverage simulations are recommended before the installation of the LoRa IoT Stations to make sure
the gateway would cover the expected area. Contact Kerlink for more information.
In a first approach, the figure below shows the RSSI of the signal vs. the distance to the end point vs. the type
of area (urban, suburban, countryside, desert). The height of the LoRa antenna is assumed to be 12 meters.
The propagation model used is based on Hata model.
The frequency is 868MHz in this case but performance and conclusions at 915MHz would be almost identical.
The RSSI is the received signal by the LoRa IoT Station.

7.3.7.3
Co-localization with GSM/UMTS/LTE transmitters
The LoRa IoT Station insures good co-localization other transmitters on the same site, and especially with
BTS, in two ways:
Limited spurious and noise generated in the BTS receiver bands
Immunity to BTS transmitter
The LoRa IoT Station is obviously compliant to all EMC emissions and immunity regulations specific to very
country. However, meeting these regulations is not sufficient to insure good coexistence with BTS when
sharing the same site.
This is why KERLINK has reinforced these specifications to allow the coexistence.
KERLINK has designed the transmitter to reduce the spurious and the noise generated in the BTS receive
bands below -80dBm in a 100KHz resolution bandwidth. This is then pretty much in line with BTS
specifications to insure co-localization between BTS.
The measurements made on the LoRa IoT Station show typical values of -85dBm/100KHz.
The receiver offers also high attenuation outside the receive band.
High attenuation of out of band blockers is obtained:
•
>105dB at +/-10MHz
•
>150dB in BTS downlink bands
This means that the blockers levels, due to the BTS, could be up to +10dBm causing no interference with the
gateway.

LoRa IoT Station
Based on this performance, this means that about 50dB isolation is required between the LoRa IoT Station
antenna and the base station antenna to avoid desensitization of the BTS.
Specifying a minimum distance between antennas may not guarantee the 50dB isolation, unless over
specifying the required distance. This is mainly due to the fact that both LoRa antenna and BTS antenna are
directive antenna. This means that the antenna gain is not omnidirectional in both cases.
BTS antenna have about 10 to 15dB antenna maximum gain but the gain above or below the antenna is
reduced by 20dB to 30dB as described below:
Mounting the LoRa antenna just above or below the 4G antenna allows then to get 20 to 30dB isolation
among the 50dB required.
The LoRa antenna can be an omnidirectional antenna. The worst case would be a 3dBi antenna which has the
“less directive” antenna pattern. An example is presented below:
We can see that the gain on the top of the antenna or below the antenna is about -15dBi to -20dBi.

LoRa IoT Station
In case of sectorial antenna, the antenna gain above or below the antenna is also significantly reduced to -10
to -15dB as shown below:
Then, taking into account the performance of the antenna, we need to get about 10 to 20dB more isolation
to meet the 50dB isolation between antenna.
A gap of 1 meter between antenna would insure 30dB additional attenuation.
Therefore, our recommendation is to have the LoRa antenna just above the BTS) antenna with 1 meter gap
min.
Placing the LoRa antenna below the BTS antenna could be also possible. However, this is not recommended
as reception could be impacted by metallic structures in the close area.
7.3.7.3.1
LoRa IoT Station 868
Co-localization is possible with the following BTS:
- EGSM900, GSM1800, GSM1900
- UMTS900, UMTS2100
- LTE800, LTE 900, LTE 1800, LTE 2100, LTE 2300, LTE2600
The most difficult use case is the LTE 800 band that is very close to the 868MHz band. Actually, the end of the
LTE 800 band is 862MHz whereas the beginning of the 868MHz band is 863MHz. Insuring -80dBm/100KHz at
862MHz while transmitting at 863MHz or even at 868Mhz is not achievable with the state of the art of SAW
filters. Therefore, the LoRa IoT Station has a limited transmit frequency range of 865-873MHz. The 863865MHz range cannot be used on transmit side. This limitation allows usage of SAW filter offering low
insertion loss at 865MHz but sufficient attenuation at 862MHz. These SAW filters are designed specifically for
KERLINK as standard SAW filters on the shelf do
do not achieve such performance. Based on these specific SAW
filters and limitation of the TX frequency range (865MHz-873MHz) the LoRa IoT Station also meets the 80dBm/100KHz spurious limit in the LTE 800 band.

Fresnel ellipsoid
Radio waves generally travel in a straight line from the emitter to the receiver. This is obviously true when
there are no obstacles between the transmitter
transmitter and the receiver. However, there are, most of the time,
some obstacles between the transmitter and the receiver. Then, the radio waves bump into the obstacles
and are reflected or diffracted with dephasing. These diffracted waves when arriving on the receiver can
cause phase cancelling with the straight line signals reducing the received power (fading). The fading effect
depends on the distance between the receiver and the emitter, the nature of the obstacles and the
associated out of phase.

Figure 25 : Fading effects due to obstacles
To minimize the fading effects, obstacles in a “Fresnel ellipsoid” must be avoided.
The Fresnel ellipsoid is a theoretical ellipsoid located between the transmitter and the receiver.
The radius of the ellipsoid is defined as follows:
Where:
•
•
•
•
•
d1 = distance from Tx antenna
d2 = distance from Rx antenna
f = frequency
c = celerity (3E8 m/s)
r1 = radius at the distance d1
A global rule is that 60% of the Fresnel ellipsoid must be clear of obstacles.
In case of buildings between the end point and the LoRa IoT station, the antenna height must be adjusted to
make sure the building is not close to 60% of r1.

Be careful, if the antennas heights are not sufficient, then the ground (earth curve) can get inside the Fresnel
ellipsoid and overrule the 60% criteria.
Figure 27 : Fresnel ellipsoid and earth curvature
Example:
An end point is located at 3500m from the LoRa IoT Station.
The LoRa IoT Station is installed on the roof of a building. The building roof is 30 meters long vs 20m large.
What is the required height of the LoRa antenna for have an optimized reception?
Answer:
If we want to receive end points i.e. 360° area coverage, it should be better to have the antenna located in
the mid of the building root.
The antenna is therefore at 15m from the edge of the roof.
Then we have:
• d1 = 15m
• d2 = 3600 -15 = 3585m
