Nova436Q Outdoor 4x1W Two-Carrier TDD eNodeB Installation Guide
As a two-carrier eNB, the Nova436Q hardware unit contains two separate eNBs inside one shell. Having
two carriers provides versatile options in how you operate the eNB. The available operating modes are
described in the next section, Features.
The Nova436Q's primary cell (Pcell) is referred to as Cell 1. The secondary cell (Scell) is referred to as
Cell 2. The 436Q has four antenna ports and supports either one 4-port or two 2-port Radio Frequency
(RF) antenna installations. Each eNB comes pre-configured to simplify the installation. Baicells provides
operators with local and Web-based Graphical User Interface (GUI) software applications to configure and
manage individual eNBs and Customer Premise Equipment (CPE).
Additionally, Baicells offers a centralized Software-as-a-Service (SaaS) solution called CloudCore.
CloudCore includes all of the key LTE Evolved Packet Core (EPC) network functions, an Operations
Management Console (OMC) for managing multiple sites across the network, and a Business and
Operation Support System (BOSS) for subscriber management.
This document provides a general description, guidelines, and procedures for installing, entering basic
configuration information, and verifying the operational status of the Nova436Q eNB. To view a video

1.2 Features

The two-carrier Nova436Q eNB can operate in one of several modes:
• Single Carrier (SC)
• CA mode (based on software license)
DC/split mode (based on software license)
•
• HaloB mode (embedded in the base software)
• Citizens Broadband Radio System (CBRS) Spectrum Access System (SAS)
SC describes a scenario where the operator wishes to use only one of the two available cells in the eNB.
This may be necessary for operators who have limited licensed spectrum or who are planning to use the
second carrier later as their network grows. In SC mode, only the primary cell (Pcell), aka Cell 1, is used.
CA provides the ability to aggregate channels from across the full CBRS range, even channels that are not
adjacent. Using CA essentially doubles the downlink capacity when all users have CAT6 or later CPE.
DC (split sector) mode enables the operator to run the 436Q as two independent carriers for split sector
coverage.
HaloB allows the eNB to function with embedded Mobility Management Entity (MME) capabilities on
board so that the eNB operates independently from the usual cloud connection. HaloB is standard in the
Nova436Q as part of the basic software. This enables the user to migrate core network functions to the
eNB.
CBRS SAS is a multi-vendor SAS database where CBRS spectrum use is managed dynamically across
operators. The CBRS band covers 3.55–3.70 GHz. Operators must sign up with a SAS provider, which
handles the dynamic frequency assignment and release process. Baicells provides FCC Part 96 certified
eNBs, including the Nova436Q, and CPEs that operate within the Part 96 rules for CBRS. The Baicells eNBs
and CPEs use a Domain Proxy (DP) to connect to the SAS server by leveraging the existing connection with
the OMC.
