Tele 2 explained that refarming is carried out from a lower technology

To further increase the network capacity, two or three 2100 MHz bands have been allocated to 4 G in a number of territories. The remaining frequencies will continue to support 3 G- supporting devices , such as ATMs and IOT sensors.

(2G/3G) to a higher france cell phone number list one (4G). " Higher technology allows more traffic to be passed with the same spectrum volumes and number of sites. However , when refarming, it is necessary to take into account the penetration of subscriber devices with 4G support - they are still far from everyone - and the capabilities of the equipment, including its availability. We will continue to refarm, trying to find a balance between all of the listed factors ," - commented a representative of the Tele2 press service .

The press service of PJSC MTS noted that refarming is an effective way to overcome the frequency deficit. "As part of technological neutrality, MTS is actively transferring the radio frequency spectrum used by previous technologies to develop networks of the current standard. We were the first of the operators to use the GSM 1800 MHz range for LTE needs in 2015, and since 2019 - UMTS (3G) 2100 MHz frequencies. The 900 MHz range is also reused. Today, MTS has deployed LTE 1800 networks in most regions of the Russian Federation, and LTE 2100 networks in 18 regions. The company will continue to refarm frequencies as subscribers stop using 3G smartphones. In the future, with the advent of 5G networks in Russia, operators will also refarm the 4G range," the operator's press service said.

Igor Guryanov, CEO of Spectrum Management LLC, believes that operators will most likely activate LTE functionality on already acquired multi-standard base stations. " This issue has been going on for a long time, and basically there will be a complete or more significant shutdown of 2 G and 3 G carriers . As a temporary measure, this will increase the capacity of LTE networks , primarily due to the further shutdown of 2 G carriers in the 1800 MHz range and 3 G in the 2100 MHz range. Optimization is also possible in the 900 MHz range, but it is largely limited by the conditions of compatibility with existing government users in this range. Due to the expected reuse of existing equipment, refarming costs should not be significant ," he believes .
