Impact on LTE networks: capacity and coexistence

“

Deploying a new technology is rarely free. While NB-IoT enables amazing new applications, it has a measurable impact on existing LTE network. Understanding this impact is crucial for network planners to make some informed decisions. We are going to discuss about the impact of two different deployment modes in case of the in-band and guard-band NB-IoT on LTE. In case of in-band, we know the NB-IoT operate inside the LTE career spectrum and share the same physical resource blocks. On the other side, in guard-band, NB-IoT utilizes the unused spectrum between LTE carriers. It avoids direct PRB competition, but affects the power contribution. Let's look into the impact of in-band deployment where NB-IoT operates inside a LTE career spectrum. The most direct impact on LTE performance happens in this particular scenario because NB-IoT and LTE services, they compete for the same physical resource blocks and they share the same career spectrum. If we look at the impact, the first impact is on…
