How will the COSMOTE 5G network work?

The 5G network will operate in three different frequency ranges, which will complement each other in order to ensure that, whether you are connecting from a remote rural area or a densely populated urban setting, you will be able to enjoy all the infinite possibilities this new technology has to offer!

How? These three frequencies are designed to work like different pieces in a puzzle: 

Mid-Band 3.500 Mhz

This frequency is ideal for densely populated urban areas or large open spaces such as stadiums, where multiple devices are used simultaneously and high capacity is required.

Its key features include ultra-high speeds that will initially reach or exceed 1 Gbps, very high network capacity, virtually zero response time (latency) and a limited coverage range.


Mid-Bands 1.800/2.100 Mhz

At the middle level are the frequencies best suited for urban centers since they combine high speeds with good geographical coverage, therefore offering satisfactory capacity and adequate response time.


Low-Band 700 Mhz

Low-band frequencies have speed performance similar to 4G and very large geographical coverage, which is their main advantage. The range of coverage in this range is not affected by obstacles such as buildings, adverse weather conditions, etc., rendering it an ideal solution for the countryside and offering reliable connectivity when connecting from either indoors or outdoors.
