We’ve updated our Cellular Spectrum Guide – the latest issue is v10.0 for Q2 2019. There have been a few significant changes in the last quarter including 5G and 900MHz spectrum swaps.
EE have launched their 5G service and the initial 5G cells have been deployed using a 40MHz channel in the 3400-3600MHz (N78) band. Vodafone have announced that they will be launching in July and we’ve added details of the channel that they are expected to use (although this hasn’t been officially confirmed).
As we’ve mentioned before, 5G currently works in ‘non-standalone’ mode, where each 5G base station operates under the control of an existing 4G base station. Further channels and radio bands can be expected to be added over time and, of course, new 5G-capable survey devices will be needed before anyone can actually survey any of these 5G cells.
Traditionally, Vodafone and O2 have shared the original ‘Primary’ GSM-900 band between them – the original sharing pattern saw the operators using alternative groups of channels that gave them two sets of allocated channels each in a pattern that looked like this – VF 4.7MHz, O2 7.6MHz, VF 7.8MHz, O2 4.8MHz.
All UK networks have been engaged in a process of replacing GSM with 3G or 4G services in the 900 and 1800 bands for the past few years and the relatively narrow alternating allocations in the 900 band were seen as a barrier to the efficient reuse of that spectrum, so VF and O2, with Ofcom’s permission, agreed to swap the middle parts of the allocation.
This has led to a revised shared allocation in the P-GSM900 band that looks like this – VF 12.3MHz, O2 12.8MHz – which offers the potential to retain some GSM capacity but refarm the remainder for 3G (UMTS900) or 4G (LTE900) services.
The swap began earlier this year and RF Surveyors will already be able to notice VF cells being broadcast on channels that were previously used by O2 and vice versa. There are also new 3G and 4G channels springing up that hadn’t been used before.
