MobileAccessVE WiMAX Instant Coverage Solution User Manual IX

1 Overview

MobileAccessVE WiMAX solution provides enhanced, cost effective in-building WiMAX coverage
for enterprise environment. This solution is quickly and simply deployed using the existing cable
infrastructure to provide instant MIMO or SISO WiMAX coverage without requiring the
installation of new cables and without affecting existing LAN services. MobileAccessVE minimizes
disruption while providing a scalable and flexible solution at a significantly lower total installation
cost.

The VE solution distributes WiMAX wireless service from the service provider‟s equipment and
Ethernet services from the corporate LAN, to Access Pods installed throughout the enterprise.
The Access Pods distribute the WiMAX services via integrated internal antennas (or external
antennas for additional coverage optimization), and also provide Ethernet connectivity to the
LAN terminals. The MobileAccessVE solution seamlessly coexists with the Enterprise LAN and
does not consume LAN capacity.

The VAPs are distributed on each floor and plug into standard Ethernet jacks already installed at
the enterprise site. They are powered via PoE technology and managed via a VE Control Unit

(VCU) located in the floor‟s communication shaft for site coverage that requires more than one

VCU (each VCU supports up to 12 VAPs), several VCUs (up to 12) can be aggregated under a
single VCU serving as Master. The Master VCU provides the interface to the capacity sources
(the service provider‟s equipment) and for management of all units.

This enhanced WiMAX coverage solution can be easily and quickly installed with minimal
disturbance to the enterprise. In less than a few hours, with no additional cables required, a
scalable and flexible solution is provided at a significantly lower total installation cost.

The following figures illustrate

In a single-tier installation, the VCU is connected to the service provider‟s equipment and to the
Ethernet switch and distributes Ethernet and WiMAX services to up to 12 VAPs distributed over
one more adjacent floors.

System Architecture

Multi-tier installation includes the Master VCU that supports up to twelve Slave VCUs. In this type
of installation the provider‟s services are fed to the Master VCU through which the Slave VCUs
are controlled and managed.

Figure 1-2. Multi Tier MobileAccessVE Installation

1.1 System Architecture

Main elements - The MobileAccessVE solution is based on the following main elements:

 VE Control Unit (VCU) – Control Unit that can serve either as a Master or a Slave and

interfaces the other VCUs (in case of Master) or the VAPs (when serving as Slave). The
Master or Slave mode is automatically detected according to the VCU's physical connection.
If a connection to another VCU is detected the VCU will be identified as a Slave; otherwise it
will assume the role of a Master.

 Master VE Control Unit (Master VCU) – installed in the main communication (IDF)

closet, interfaces to the WiMAX BS and Ethernet switch and provides secure, central
management to (up to twelve) VCUs and all connected VAPs. VAPs can also be
connected to the Master VCU.

 Slave VE Control Unit (Slave VCU) – installed telco/IDF closet. Used to expand

coverage to additional floors. Each VCU interfaces the Master VCU and up to twelve
VAPs and twelve Ethernet connections.

The Slave VCUs distribute WiMAX MIMO or SISO signals to each VAP along with PoE and
Ethernet signals from the Ethernet switch, throughout the existing CAT-5e infrastructure.

The Slave VCUs are connected to the Master VCU using CAT-6 or CAT-7 cables.



VAP (VE Access Pod)

the floor to provide maximum WiMAX coverage. VAPs provide RF coverage via integrated,
internal antennas. VAPs are also equipped with interfaces for external antennas that can be
used for special coverage requirements. VAPs are remotely powered from the VCU using
Power over Ethernet (PoE) – no local power required.

2 MobileAccessVE WiMAX Instant Coverage Solution User Manual

– These are pluggable antennas distributed at strategic locations on

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 VAPs, consult with
MobileAccess support.

The following figure shows the MobileAccessVE solution architecture (multi-tier).

Overview

Figure 1-3. MobileAccessVE Basic Architecture

The Master VCU distributes the converged WiMAX services from the service provider‟s equipment
to the Slave VCUs. At the Slave VCUs, the wireless services are converged with Ethernet service
and routed to the VAPs via the Ethernet LAN CAT-5e/6 cabling infrastructure.

The VAPs distribute the WiMAX services via integrated internal antennas or external antennas
and provide Ethernet connectivity to the LAN terminals.

Figure 2-1. WiMAX VE Basic Architecture

2.2 Infrastructure Requirements

Ethernet standards specify that the maximum distance between an Ethernet switch and
appliance (computer, WLAN AP etc) shall not exceed 100m (300ft). Therefore, when VE shares
the IT LAN, the maximum distance for a given cable run, cannot be longer than 100 meters
(300ft) between the Ethernet switch and appliance, including all patch cords (from switch to
VCU, from VCU to patch panel, from RJ-45 outlet to VAP, and from VAP to appliance).

MobileAccessVE WiMAX Instant Coverage Solution User Manual 13

Infrastructure Requirements

Typically the horizontal cabling system will be connected to patch-panels in the communication
rooms. The entire cabling system (including the patch panels and patch cords) shall adhere to
the CAT-5e (or CAT-6) standard. Specifically all pairs of the CAT-5e cable should be wired in the
patch panels (and patch cords).

1. IDF/telco closet space for one VCU (48.3 x 30 x 4.44 cm).

Note: When planning the IDF/telco shaft, take the RF equipment (Picocell/Microcell or
BDA) and the VCU in to consideration.

2. 350 Watts of AC power to the VCU IDF/Telco closet.

3. Building infrastructure:

 Category 5e or CAT-6 cabling, Shielded Twisted Pair (STP)
 24 AWG minimum diameter for CAT-5e cabling
 Dedicated CAT-6/7 STP cable from Master VCU to Slave VCUs with run lengths NOT

exceeding 100m (300ft) and not shorter than 10m.

NOTE: in certain deployments the master-slave CAT-6 STP connection may be shared
with Ethernet signals - refer to Appendix VE Connections in Central Ethernet Source
Topologies for more details

 CAT-5e/6 STP cable from VCU to each VAP with run lengths NOT exceeding 100m

(300ft) and not shorter than 10m (33ft). VAPs can be connected over existing CAT-5e/6
cabling infrastructure and existing Ethernet jacks without affecting the LAN.

Note: Verify with the IT department that the existing cables support the VE installation.
If available, review the infrastructure documentation to determine cable types and
lengths. If the cable information is not available, attempt to visually identify the cable
type. Depending on the cable vendor, the cable type may be listed on the cable sheath.
It is recommended to use a Fluke cable tester to measure the cable length of the most
remote VAPs.
