Use of the 57-64 GHz frequency band
In the national frequency plan, the 57-64 GHz frequency band is allocated to different radio services on a primary basis such as fixed and mobile services, various satellite services and space research. In addition, pursuant to the Free Use Regulations the 57-66 GH frequency band permits use for indoor wireless data transfer with a maximum permitted average effect of 40 dBm e.i.r.p. as described in the standard, EN 302 567. Maximum permitted spectral power density is13 dBm/MHz. Use through a fixed outdoor installation is not permitted without a transmitter licence from Nkom.
Due to the propagation features on this frequency band and the large bandwidth that is available, this frequency band is also well-suited to radio links with distances up to 1km and transmission capacity of several Gbits/s. The short distances and the fact that the antennas that are used are very directive mean that the frequency planning is easy and that the frequencies can be reused often. When using this frequency band for radio links there are still a number of factors that must be taken into consideration for other radio services on the same and surrounding frequency bands, including for ITS equipment (ITS - Intelligent Transport Systems) on the 63-64 GHz band in accordance with ECC Decision (09)01.
Based on these assessments, the Norwegian Communications Authority (Nkom) has opened up the 57-64 GHz frequency band for radio links. It is Nkom's intention that the use of the frequency on this band will be based on the technical specifications in ECC Decision (09)01 (Use of the 57-64 GHz Frequency Band for Point-to-Point Fixed Wireless Systems).
Nkom issues individual transmitter licences for radio links on the 57-64 GHz band in accordance with the procedures described on Nkom's website.
