With so many different communications and signal systems there is the need for both extensive knowledge and the correct equipment to be able to achieve high-quality signal strength and capacity.
Especially important are the critical situations that could occur when organizations and governments who have the responsibility in ensuring communication functions even in those circumstances when everything else fails to work in the society.

MIC Nordic can TETRA and RAKEL

MIC Nordic has extensive experience in projects for the police, ambulance, emergency services, detention centers and prisons. We are involved in creating a reliable infrastructures for mobile communication. For this we have specially designed, robust, safe and environmentally friendly solutions.

We provide better mobile indoor coverage for FM, TETRA / RAKEL, GPS, 1G, 2G, 3G, 4G, and are actively involved in research and development of 5G technology and HetNet.

Since the launch of NMT/1G in 1981, there has more or less a new mobile generation every 10 years. Development moves forward quickly. We have all become accustomed to 3G and ordinary people now talk about 4G. In our world we are however talking ahead about the next phase, 5G, what Ericsson calls HetNet – heterogeneous networks; which are a combination of several different networks.


FM – radio stations on the FM broadcast band, 88-108 MHz.

TETRA / RAKEL and two-way radio

TETRA – is a digital communication radio standard. The word is an abbreviation of Terrestrial Trunked Radio. The concept of “trunked” implies that several transmitters can share the same resources and only take up space on the band when someone is talking. It allows emergency calls from rescue teams and other services that need to have space in the system at all time regardless of transmission load.

TETRA is the underlying technology in RAKEL which is the national communications systems used for collaboration and management. It was developed specifically for government departments and organizations ensuring it will always function in crisis situations when nothing else works in the society.

RAKEL –one of the largest secure TETRA radio communications networks in the world used by police, ambulance, rescue and coastguard services. The system is used in association with emergency situations even by towns and cities, energy companies, local traffic and municipalities, among others. The RAKEL communication system is used even by the armed forces, prison services and the government Customs and Excise.

RAKEL is developed to provide good reception, and covers practically the entire country. The system therefore must be reliable and work when everything else fails, when there would then be a great coverage demand, durability, battery backups and generators that can ensure sustained communication. MIC Nordic has many years of experience providing both secure and robust solutions for TETRA and RAKEL based networks.

Communication radio -Two-Way Radio is an analog radio transmitter/receiver, the predecessor tothe digitalcommunicationradio. The analog two way radios are still used, particularly in operations within aviation, maritime, rescue services, the mining industry, trucking companies, taxi business and construction companies.


GPS – Global Positioning System is used in navigation systems and determines the position as well as latitude longitude and altitude. GPS is also used for synchronization of time references to computers and watches. It gives a very accurate synchronization and is used for amongst others in the TETRA standard.


2G – or GSM is a European telecommunications standard which today covers the vast majority of mobile subscribers around the world. 2G is the second generation mobile communication and was launched in 1991. Unlike the previous analog system all phone calls became digitized and SMS (short message service) was launched as one of the new mobile data services. Together with the launch of 2G the old analogue system was named 1G.


3G – or UMTS, when the third generation mobile phone was launched the transmission speeds became higher. This is as much as 40 times faster than with 2G and with the ability to send and receive moving images and graphics in the mobile phone.  3G is also known by many as “mobile broadband”.
Other standards are also branded 3G; CDMA-450 which is also called Turbo 3G.
This technology is now owned by the company Net1 who offer mobile telephony and broadband use in Scandinavia.


4G – or LTE (Long Term Evolution), is the last step before the introduction of 4G in the European 3G networks. LTE is sometimes referred to as 3.9G. 4G is the fourth generation mobile communications with higher user speeds of data traffic and Internet surfing. With 4G, it is possible to surf up to ten times faster than 3G. The mobile network is completely digitized and totally IP-based.


5G – fifth-generation mobile networks. The name used to describe the next development step. The 5G standard is not currently available but if we are to follow previous mobile network 10-year cycles it will most probably be launched sometime around 2020.


HetNet– so-called heterogeneous networks is a term to which Ericsson amongst others uses for the next step of development. HetNet is a combination and interaction of several different networks, such as Wi-Fi and mobile networks. Mobile telephony complemented by other wireless technologies will enhance the coverage and reception even further and makes it possible to use base stations for indoor use.
