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.

Infrastructure Requirements and Layout Planning

2.3 Coverage and Installation Planning

Note: The following section provides the information required for planning the VAP installation
on a single floor. In a multi-tier installation, this procedure is performed for each individual floor.

The WiMAX coverage area of each VAP is affected by the density and type of environment to be
covered. Therefore, it is recommended to determine the location in two phases:

 Plan the

floor and then

 Select

mounted on a wall or placed on a desk and an option for an external antenna is available.

The supplied services (WiMAX only or Ethernet and WiMAX) depend on the jack to which the
VAP is connected:

 If the jack supports an active Ethernet connection – the VAP will distribute LAN traffic along

with the WiMAX service.

 If the jack is not currently active (not connected to an Ethernet switch) - the VAP will

distribute only WiMAX.

This section provides information on coverage criteria in various types of environments (Open,
Standard, Dense and Combined) and provides rules-of-thumb for various installations of the
VAPs.

Note: Section 2.4 provides a detailed example of installation planning in various types of
environment. It is recommended to review this example after reading this section.

2.3.1 Types of Environment

This section describes the different types of installation environments and provides guide lines
for best coverage of each type of space.

The coverage guidelines in this section are conservative “rule of thumb” estimates of RF

coverage per VAP, meant to be used in scenarios in which detailed designs are not performed.
When the coverage layout is designed, the coverage per VAP is expected to increase by up to
33%. Coverage estimates in this section assume 25% overlap between the coverage areas of
neighboring VAPs to ensure robust, full coverage throughout the enterprise with no “dead
zones”.

An environment with minimum of obstacles (such as walls). This type of space can be a large
conference or meeting room, cubical areas, lobby or atrium areas.

Table 2-1: Open Environment Installation Distances

2.3.1.2 Standard Environment

A traditional office environment with offices, hallways and scattered cubicles.

Table 2-2: Standard Environment Installation Distances

2.3.1.3 Dense Environment

A dense environment consists of a relatively large amount of walls, offices, equipment, tall file
cabinets, bookshelves and other items that could potentially impact the wireless signal.

Examples for this type of environment are dense offices, hospitals and manufacturing spaces.

Table 2-3: Standard Environment Installation Distances

2.3.1.4 Combination of Environments

In areas with combinations of environments of various densities, place the VAPs on the border
between the different types of areas – closer to the denser area.

For example, in a cubical area with the outside wall having offices, simply locate the VAPs a little

closer to the outside offices

To ensure maximal coverage, VAPs can be re-located or added. If a coverage gap is detected,
the VAPs can be re-located until the coverage gaps are filled.

2.4 Planning VAP Layout

This section describes the steps for planning the VAPs along the covered floor. An example of
planning map is attached at the end of this section.

Note: It is highly recommended to use a floor plan when planning the VAPs locations.

2.4.1 RF Coverage Factors

It is important to note the type of factors that can severely impact RF coverage which should be
avoided:

 Metallic structures such as elevators, high file cabinets and some moveable metallic

partitions severely degrade RF signal and all efforts should be made to locate VAPs in front
of or above metallic objects (desks, filing cabinets) to allow the signal to propagate.

 Wall materials such as concrete, tile and cinderblock along with bathroom fixtures typically

have fairly high signal attenuation and should be considered as dense spaces.

 Types of glass (typically exterior or mirrored) that have metallic coatings on it which can

affect RF coverage, however that is typically not encountered inside a building.

Infrastructure Requirements and Layout Planning

2.4.2 Mapping Locations

To map the VAP Locations

1. Map out the available Ethernet jack locations: mark all the CAT-5e/6 drops locations on the
floor plan map.

TIP: The size and number of the ceiling tiles can be used to measure distances.

2. Using the floor plan and the VAPs coverage guidelines (as given in 2.4.3), mark the
approximate location of each VAP in the facility.

VAPs may be added (or removed) at anytime for optimal coverage.

3. For each jack to be used for connecting a VAP, check if the jack is already connected to the
Ethernet switch (via the patch panel). Record the connections for each jack, for reference.

4. Connect the Ethernet cables corresponding to the selected jacks according to section 3.4.1.

5. It is also recommended to check the area in which the VAPs are to be installed and make
sure that the installation is feasible.

2.4.3 Connecting Directional Antennas

Each VAP has an integrated internal antenna that provides isotropic radiation as well as two
interfaces for external antennas which enable connecting directional antennas to VAPs installed
near outer walls in order to prevent interference. It is then required to configure the VAP to

operate with the external antennas – see section 7.3.

MobileAccessVE WiMAX Instant Coverage Solution User Manual 17

Planning VAP Layout

2.4.4 Installation Plan Example

The Following figure shows a floor plan map with all required marks:

Figure 2-2. Floor Plan Example

Notes:

 The red VAP coverage circles are approximately 41, 56 and 64 foot (13.5, 19 and 21 m)

radius for the small, medium and large circles respectively (drew according to the guidelines
given in section 2.3.1).

 VAP 3 is surrounded by dense objects, the bathroom and stairwell which would reduce

coverage in that area by the other VAPs.

 VAP 5 is an example of a unit that provides good coverage down the hallways.
 VAPs 11 and 13 are placed closer to the offices to cover them well but on the open side will

actually cover a much greater area which is why the coverage is larger and shown here
more as an oval than a circle.

 The area between VAPs 7 and 14 outside the bathrooms would probably be the lowest

coverage spot in the building because of the bathrooms and stairwell on either side of that
area. If after the system installed, this area is still a little low on coverage, a VAP can be
added, but it may also be covered by VAP 14.

Note: The plan can be modified at any time by moving the units around or by adding units.

Master VCU front panel RF ports (MIMO1 and MIMO2).

Note: In SISO service mode, only the MIMO 1 RF port is relevant.

Power on the signal sources.

Note: The RF Source LED (see following figure) of the connected port on the Master VCU
should be lit GREEN, indicating that the Master VCU senses the RF signal from the
source at the expected level (according to Max Expected Pin). In case the LED remains
RED after connecting the capacity source, verify that Max Expected Pin is configured
properly and that the service is enabled.

4. Connect the Master VCU VAP ports to the Slave VCUs VCU/VCH ports via the patch­panel that feeds the dedicated CAT-6 or 7 cabling system.

22 MobileAccessVE WiMAX Instant Coverage Solution User Manual

NOTE: After the Slave VCUs are connected, verify that that the Master VCU VAP Status LEDs,

3. Connect the Slave VCU VAP ports to the patch-panel that feeds the existing structured CAT­5e/6 cabling system.

4. According to VAPs layout plan (as explained in section 2.4.2) connect the Ethernet switch
cables (see section 3.4 for more detailed explanation):

 If the jack to be used is already in use (connected to Ethernet switch) – disconnect it from

the Ethernet switch and re-connect it to the corresponding Ethernet port in the Slave VCU
front panel.

 Jacks not in use will be connected only to the Slave VCU.

3.4.1 Connecting VAP Ethernet Cables

For VAPs installed on currently ACTIVE Ethernet ports - shift the relevant Ethernet LAN
connections as follows.

VCU Unit Installation and Configuration

MobileAccessVE WiMAX Instant Coverage Solution User Manual 25

Installing Slave VCU

For VAPs installed on currently INACTIVE Ethernet ports – connect as follows.

NOTE: After the Slave VCUs are installed, and connected to the right ports in the patch panels,
you can proceed with VAP installation as described in chapter 4 . However it is recommended to
first complete the VCU provisioning (see section 3.5) so that when installing the VAPs they will
instantly provide the wireless service (and the installer will be able to check the coverage).

3.4.2 Operation with LAN utilizing Power over Ethernet (PoE)

Power over Ethernet (PoE) is a technology that enables passing electrical power over the
Ethernet cabling. Power can either come from a PoE-enabled Ethernet device (e.g. switch) or
from a “mid-span” device built for "injecting" power into the Ethernet cabling.

PoE can operate over two different pairs in a CAT-5e/6 cable - these two methods are referred
to as „alternative a‟ and „alternative b‟. All PoE compatible appliances such as WLAN APs and IP
Phones support both alternatives and automatically detect and use the power on the appropriate
pairs (alternative a or b).

MobileAccessVE supports sharing LAN infrastructure that use either 802.3af PoE or 802.3at PoE.
Both alternative a or b are seamlessly supported through the VE system.

26 MobileAccessVE WiMAX Instant Coverage Solution User Manual

3.5 Provisioning the Master VCU

This section describes how to set the basic parameters required for operation and remote
management of the Master VCU using the Web GUI. The configuration dialogs are fully

described in Chapter 5 .

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.

Notes:
The initial configuration of the Master VCU is performed via local connection (using a
cross-cable and connecting to VCUs default IP address). After performing the initial
configuration and assigning the Master VCU an IP, the system can be connected,
monitored and configured via a remote management connection.
The configuration and management of all of the system units (VCUs and VAPs) is
performed via the Master VCU unit (local or remote connection).

It is recommended to place the VAPs on top of desks, cube walls, filing cabinets or higher on
walls so as to maximize the provided coverage per VAP.

Note: Mounting a VAP beneath a desk or other low location (e.g office corner) decreases the
effective coverage of the VAP and therefore a higher number of VAPs would be required to cover
the same area.

When installing the VAPs, consider the following:

 Placing the units (whenever possible), in an open area
 Availability of CAT-5e/6 infrastructure
 The VAPs plug into standard (RJ-45) Ethernet connection jacks.
 If the jack to be used is already connected to Ethernet switch. For more information see

2.4.2 and 3.4.

 Aesthetics of the VAP location

4.1.2.1 Desk Mount

VAP Installation and Provisioning

Ethernet standards specify that 100m (300ft) is the maximum distance between an Ethernet
switch and appliance (computer, WLAN AP etc). This is relevant when MobileAccessVE shares
the IT LAN. The distance includes all patch cords (from switch to VCU, from VCU to patch panel,
from RJ-45 outlet to VAP, and from VAP to appliance).

1. Review the IT documentation (may be available from your IT department) to determine

cable types and lengths.

2. Check the lengths of the patch cords being used and verify the end-to-end distance does not

exceed 100m (300ft).

3. A Fluke cable tester can be used to measure cable length.

9.4 No Service from Connected Access Pod

This requires physically accessing the Access Pod to check the LEDs, and accessing the Access
Pod through the Web GUI to verify the Access Pod configuration.

1. Physically view the Access Pod and confirm that both LEDs on the Access Pod are lit:

 Power LED (Green) is OFF – either no connectivity to the VCU or the VAP is faulty. Try

replacing the VAP. Try connecting the VAP directly to the VCU – if the Power LED is lit
check the cable and the patch cords.

 Activity LED is constantly blinking – the Access Pod cannot initialize due to exceeded

cable length. Try using the closest free RJ-45 jack fed with a different cable.

2. Check other Access Pods connected to the same VCU.

3. Verify that the VAP configuration as follows:

 Connect to the VCU using the MobileAccessVE Web GUI application (see 5.1).
 In the VCU Config tab, click the RF Parameters sub-tab and verify that the Service

VE Connections in Central Ethernet Source Topologies

VE Connections in Central Ethernet Source Topologies

This section describes the VE site installation for sites whose Ethernet services are provided from
a single Ethernet source in the communication room and distributed throughout the site by
daisy-chaining Ethernet switches from the central source.

In VE installation, any switch located in the path between the VCU and the VAPs will block the
wireless signals:

The Bypass option allows bypassing the switch by enabling the transport of Ethernet signals over
the cable connecting the Master VCU to the slave VCU. (In a typical VE the cable between the
Master and Slave VCUs is a dedicated CAT-6/7 cable used only for VE).

The Ethernet signals are combined with the wireless signals at the master VCU, separated at the
slave VCU and connected via the Bypass port to the switch.

The wireless signals are then re-combined by the slave VCU with the Ethernet signals (from the
Ethernet Switch Ports) and transported to the VAPs and connected PCs.
