VIAVI Webinar: Learn how to overcome the challenges of deploying 5G services in in the C-band spectrum

Midband (or C-band) is considered the “waterfront property” of RF spectrum for 5G. It offers the best compromise between RF coverage and RF bandwidth, and with 100 MHz of bandwidth, C-band can truly enable the highly hyped enhanced mobile broadband (eMBB) use cases. Yet,...

Understanding FDD/TDD carrier aggregation for 5G

In general, FDD is considered better for coverage and TDD better for capacity Mobile operators are looking to carrier aggregation (CA), which allows them to use multiple sub-6 GHz spectrum channels simultaneously, as a method of increasing the bandwidth and speeds of their 5G networks....
