IRIS2 – Europe's response to Starlink.
The European Commission has signed a 12-year concession contract with the SpaceRISE consortium for the development, construction and operation of the IRIS2 satellite network. The network is intended to serve both public institutions and private entities. It will make it possible to provide secure communications for government institutions, emergency services and the armed forces. At the same time, the system is expected to provide high-speed Internet access to residents of sparsely populated and hard-to-reach areas, helping to reduce the so-called “digital divide.”The project involves launching a total of 290 satellites into low and medium earth orbit. This hybrid configuration, combining the advantages of both types of orbits, is expected to provide both, wide coverage and high throughput. The system will operate based on the principle of satellite constellation, meaning that multiple satellites will work together to form a network that will provide continuous Internet access even in the most remote regions.
Will IRIS2 match the popularity of Starlink, which is already used by more than 3 million users worldwide? Starlink is also relatively popular in Europe. The emergence of a competing solution will certainly have a positive impact on the consumer market, yet, as of today, it is hard to predict whether the emergence of a European system will be followed by the creation of regulations prohibiting the use of the American solution in Europe.
The SpaceRISE consortium is composed primarily of three European satellite network operators - SES, Eutelsat and Hispasat. They are supported by a number of companies in the space, military and telecommunications industries. Among them are Thales Alenia Space, OHB, Airbus Defence and Space, Telespazio, Deutsche Telekom, Orange, Hisdesat and Thales SIX.
Although the exact timetable for the project's implementation is not yet known, it is estimated that the full functionality of IRIS2 will be achieved around 2030. This means that Europe will soon have its own independent satellite infrastructure as an alternative to solutions offered by private companies such as SpaceX.
IRIS2 is an important step toward increasing Europe's digital sovereignty. With this project, the European Union will gain independence in satellite communications, which is crucial for both, security and economic development on the continent.
Coaxial, twisted pair and fiber optic cables in low-current systems.
The CPR regulation does not directly apply to the design and construction of buildings, but it does require ensuring the fire safety of buildings, that is, indirectly, the use of cables with a certain fire-resistance class. The CPR regulation does not impose requirements on EU member states related to the use of specific cables in specific buildings. The requirements for using cables with a specific reaction to fire class in a given type of building should be based on a risk analysis made by the installation designer or other national formal and legal documents. Each member state introduces appropriate requirements for buildings on their own.In order to achieve a higher fire safety level, cable manufacturers recommend the use of B2CA-class cables in high-rise buildings (within escape routes), and special-purpose buildings that must meet very high safety requirements (e.g., hospitals, nurseries, nursing homes).

How to check a fiber optic system?
The question of how to verify the correctness of a fiber optic system comes up very often. Installers acquire basic devices for verification - an optical power meter and a light source, but they are not sure how to correctly perform the measurement itself and, above all, how to interpret the results.In the shortest terms, the measurement of the transmission method involving the use of an optical power meter and a light source allows verification of the attenuation of the entire link. The result achieved should be compared with theoretical assumptions or guidelines of the investor. The attenuation values of individual events in the optical path that are used most often are: 0.1 dB for the splice, 0.3 dB for the connector and 0.4 dB/km (for 1310 nm) for the optical fiber. For example, a 200 m section of fiber optic cable terminated with welded pigtails on both sides should attenuate no more than: 2 × 0.1 dB (2 splices) + 2 × 0.3 dB (connectors) + 0.4 dB × 0.2 (200 m of fiber) = 0.88 dB.
The measurement procedure itself should be as follows:
1. Connect the light source and the meter with a patchcord with connectors that match the devices.
Turn on both devices.
2. On the meter, press the reference measurement button (usually labelled "REF" or similar).
A value of 0 dB should appear on the screen.
3. Disconnect the patch cord from the meter. Plug the disconnected plug into the measured line (for example, into the switch that terminates it).
In this way you have connected the light source to the measured line.
4. Connect the power meter to the other side of the line using the second patchcord.
Turn on both devices.
2. On the meter, press the reference measurement button (usually labelled "REF" or similar).
A value of 0 dB should appear on the screen.
3. Disconnect the patch cord from the meter. Plug the disconnected plug into the measured line (for example, into the switch that terminates it).
In this way you have connected the light source to the measured line.
4. Connect the power meter to the other side of the line using the second patchcord.
After the above procedure, the attenuation value of the entire optical path will appear on the meter screen, which should be compared with the previously calculated expected value.

For a detailed explanation of the entire procedure, related standards, and a description of the calibration of the measurement system using 1, 2, and 3 patchcords used in various measurement scenarios, see the article "Measurements in Fiber Optic Systems - Transmission Method ”.
Use of relay outputs in the DS-KH6320-WTE1 Hikvision IP video intercom monitor.
When installing a video-intercom system, it is sometimes necessary to install additional functions to notify the user that someone has pressed the call button on the door station. An example can be installation of the system in a noisy production hall, using it by a person with impaired hearing , or a need to install signalling outside the house, so that being in the garden you would notice that someone has come.The DS-KH6320-WTE1 video-intercom monitor has two built-in relays that can be activated when the monitor starts ringing after the call button is pressed. These relays can operate in monostable (1-180 s) or bistable mode. The operating time and mode of each relay can be configured individually. For example, one relay can be connected to an buzzer with an operating time of 5 s and another to a visual indicator with an operating time of 60 s. Pairing the relays with a call button can be done using the iVMS-4200 application, after entering the remote settings of the monitor in the tab: Intercom -> Calling Linkage. Select the Enable option and choose the relay output that will be activated at the moment of calling. The relay mode and time setting can be configured directly from the monitor.
In the configuration shown above, relay 1 is linked to the call button.
When the monitor starts ringing, the selected relay is activated.
When the monitor starts ringing, the selected relay is activated.

Selection and installation of an antenna for LTE MIMO.
When selecting an antenna, it is necessary to obtain information on the location of the nearest transmitters that emit a signal in a specific standard. Such information is provided by customer service offices of the respective operators. It is also worth to verify the frequency of emission assigned to a particular service.If the base station supports several bands, e.g. LTE800, LTE180, LTE2100, and the router has an aggregation function, a broadband antenna should be used. The antenna should be chosen according to the distance between the reception site and the operator's transmitter.
- When the transmitter is located above 6 km away we recommend using the TRANS-DATA LTE KYZ 10/10 A741024 antenna (it's the best antenna offered by DIPOL for LTE networks):
TRANS-DATA LTE KYZ 10/10 A741024 antenna
- When the transmitter is located at a distance of less than 6 km away we recommend using the ATK-LOG ALP LTE MIMO 2x2 A7054_10 antenna:
The ATK-LOG ALP LTE MIMO 2x2 A7054 antenna is available in four versions: with a 5, 10, 15, 20-metre long cable
The video below shows a solution to a “slow” Internet problem caused by a weak LTE network signal. Replacing the factory antennas in the router with professional, external ones significantly improves the level of the received LTE signal, so that data transmission speeds up. The video uses a TP-Link Archer MR200 N3263 LTE router with a set of ATK-LOG LTE MIMO A7054 antennas connected to it.
