The Nokia 9926 eNodeB consists of a high-capacity baseband unit (BBU) with new LTE digital platform (bCEM2/bCAM2) and compact, wideband radio frequency (RF) units. It is designed to cut cell site congestion and dramatically increase capacity so that operators can meet growing demand while offering a smooth evolution path to vRAN and 5G.
The new BBU will almost triple the capacity of previous generation solutions, supporting up to 24 fully loaded cells and 16, 000 users in one compact d2U chassis with 50% less power consumed. It supports both TDD/FDD modes and can be mixed with existing BBUs, allowing operators to preserve their investment while enhancing their networks. The digital BBU fully supports LTE/LTE-A and is ready for vRAN/5G.
As well, the RF modules enable better scaling, feature introduction, improved reliability, and cost reduction. This is achieved by leveraging a common architecture and advanced power amplifier/filter technology across the RF platform.
