System Architecture
Main Elements -
The MobileAccess
VE
solution is based on the following main elements:
VE Control Unit
(VCU) – Provides interface to up to 12 VAPs, and the central interface for
managing the VE deployment. In Master/Slave mode, it can serve to expand the network
coverage with additional VCUs serving as Slaves and a single control point at the Master.
Slave mode is automatically detected when a Slave VCU detects that it is connected to the
Master VCU.
Master VE Control Unit
(Master VCU) – Installed in the main IDF/Telco closet, the
Master VCU interfaces with the service provider’s RF capacity sources and provides
secure, central management to up to twelve VCUs and VAP devices in any combination.
The Master and Slave VCUs are connected using
dedicated
CAT-6/7 cables.
Slave VE Control Unit
(Slave VCU)
– Installed in the IDF/Telco closet and used to
expand coverage to additional floors. Each VCU interfaces the Master VCU and up to 12
VAPs and 12 Ethernet connections.
VCUs distribute wireless service signals to each VAP along with PoE and where relevant,
Ethernet signals from the Ethernet switch, throughout the existing CAT-5e/6 infrastructure.
VE Access Pod
(VAP) – VAPs are pluggable antennas distributed at strategic locations on the
floor to provide Ethernet connection to an IP device and wireless coverage of the service via
integrated internal (or external) antennas. Power to VAPs is provided via PoE from the VCU.
Up to twelve VAPs can be connected to a single VCU using LAN cables (CAT-5e or higher).
Note: When the total number of VAPs in the deployment exceeds 72, consult with
MobileAccess support.
The following figure shows the Multi-tier VE LTE 700 MHz MIMO solution architecture.

Note: If the Master VCU supports VAPs (in
addition to VCUs), the relevant Ethernet ports
are also connected to an Ethernet switch.
