1. MC-802 Wireless WallPlate Field Evaluation
The Motorola MC-802 Wireless WallPlate is designed for multi-tenant buildings
such as hotels, healthcare, apartments, and dormitory housing. The principal goal
is to leverage the in-building telephone wiring to deploy Ethernet and wireless LAN
networks without the effort and expense of re-wiring with structured cabling. MC-
802 is part of the T3 PowerBroadband product family. The T3 system combines
proven VDSL with patented Adaptive Line Power to produce a truly unique, high
value product.
Although designed primarily for hotels, the T3 PowerBroadband system can be
deployed in many multi-tenant applications.
When evaluating the T3 PowerBroadband system with the MC-802 Wireless
WallPlate, there are three primary features that can be demonstrated:
Better wireless LAN
Hotel architecture consists of individual rooms with high RF attenuation walls, firewalls,
firedoors, and reflective surfaces. These structural elements can cause havoc when
attempting to survey and install a traditional enterprise AP from the hotel hallway. The
MC-802 WallPlate, by contrast, is installed in the guest room – right where the guest is
located. The 14dBm transmitter and high-gain custom designed antenna allow the RF
signals to penetrate several rooms.
Tamper-proof, fast installation
When installed in the hotel guest room, it is important that the wireless AP hide “in plain
sight”. The MC-802 is not marked as a WAP, and is designed to convert a standard
70mm x 114mm RJ11 telephone jack into an Ethernet and Wireless wall plate.
Adaptive Line Power
Using Adaptive Line Power, the WallPlate can be line powered over the telephone wires,
up to 300m. Combined with the form factor, Adaptive Line Power truly hides the
WallPlate AP. Adaptive Line Power shares an advantage with PoE – the device can be
rebooted by disabling and re-enabling line power at the source. This lowers maintenance
visits and eases diagnostics.
This application note will provide site survey and installation guidance. For additional material

3. Better Wireless LAN
The goal of a wireless LAN site survey is to measure the RF penetration through the building
architecture, and identify the location and method of installation.
With the Wireless WallPlate and Adaptive Line Power, every room is a potential installation site.
Thus, the site survey can be simplified greatly to determine the average room-to-WP density.
Si t e S u r v e y
Activities:
Load site survey code onto a WallPlate
Survey one room group
Load Site Survey code
Obtain the site survey code from Motorola support. Email: pbn.support@motorola.com. The
code comes with instructions to load the Site Survey code onto a T3 Switch; then push it to the
WallPlate.
Any Wireless WallPlate can be converted into a site survey WallPlate. Since each WallPlate
stores two images, you can easily switch back to production mode.
Power the WallPlate using a 12VDC regulated power supply
Site Survey code allows the WallPlate to operate without a connected T3 Switch. When running
the site survey code, the WallPlate has this hard-coded configuration:
Transmit level 14dBm
Channel 1
SSID = “Motorola-survey”
Ethernet ports disabled
Install the survey WallPlate in one room
It is generally best to locate the WallPlate on the wall where it will be installed. Install the power
adapter. After about 2 minutes, the WP will begin transmitting the SSID.
Be certain to close the doors when doing the site surveys. Signals can bounce through the
hallway and give inaccurate readings.

4. Measure the Received signal level in each adjacent room
Find the room where the signal level is -90dBm. Then, add one extra room. This is the ROOM-
to-WP density for the entire property.
In this example, the -90dBm room is the fifth room. Thus, the density will be one AP in every 5
rooms. You could also use 6 rooms without trouble. This will provide a -72dBm signal or better
in each room of the hotel with little co-channel interference.

With the WP installed in the site survey room, continue measuring RF signal strength in rooms
across the hall on the same floor, and vertically in rooms on other floors.
Note the rooms where the signal level drops to -90dBm or lower. Based on the above survey, it
can be demonstrated that the WPs installed in room 100 and 117 on Channel 1 will not interfere.
Rooms 100 and 107 are likely within the carrier detect range; but they are on non-overlapping
channels.

5. Fast Installation, Tamper proof
Activities:
Install mT2 Switch in phone room
Install cross connects for one room
Install MC-802 WallPlate in the room
Measure RF signal strength
Following these steps, the complete installation can be demonstrated. Particular attention should
be paid to the in-room portion of the installation. In hotel environments, it is critical to guest
satisfaction to get in and out of the room as quickly as possible.

Required Third Party Equipment
1. Two RJ21 Male cables, single or dual ended, approx 3 meters
2. Cross connect block (type 66, 110, Krone, etc)
3. Spool of cross-connnect wire
4. Ethernet cables to connect the T3 into the core network
Note: Type 66 cross connect blocks can be purchased with a pre-wired RJ21
connector. This simplifies the installation considerably. Use a Male-to-Male
RJ21 cable with a pre-wired 66 block. If using 110 or Krone blocks, you will need
to use a single-ended Male RJ21 cable and punch down the open ends of the
RJ21 cable. For demonstration, fan out and punch down the first three wire
pairs. The standard color codes for the first three pairs are:
White-blue pair one
White-orange pair two
White-green pair three

6. I n s t al l t h e C r o s s C o n n e c t s
Identify the line 1 wire pair. The recommended procedure is to begin replacing cross connects at
the room termination block, moving back to the PBX termination block. The reason is simple: In
most cases, the room termination blocks are marked with room numbers; whereas the PBX block
is marked with cable pairs or PBX port IDs.

The Wireless WallPlate has a built-in POTS and Line Power filter for the desk phone. Install an
in-line filter on all other phone jacks that will have a phone connected.
The terminated filter has a clipped RJ11 connector. This is purposely done to comply with
EN60950 requirements. Use a small flat blade screwdriver to lift the tab if attempting to remove
the filter.
If installing a filter on a bathroom phone, use the Unterminated filter. Remove the bathroom wall
plate and terminate the filter in the wall box using wire beans.

Enable Line Power
Line power should be enabled after the filters and WallPlate have been installed. Line power is
safe for use with telephony equipment; but it will ring the phones if the filters are not installed first.
Cmd: interface dsl power enable port(1-3)
From the Switch CLI, check the status of the WallPlate using “show interface dsl status”
• READY LED will be ON when power is supplied
• STATUS LED will flash with WLAN traffic
• LINK LED will flash fast during link training, flash slow when not training, and will be solid
when the VDSL link is established

10. M o n i t o r i n g t h e N et w o r k
Following the above steps is useful in demonstration or evaluation of the installation and RF
signal propagation. During installation, and follow-up evaluation, the system should be monitored
to check for network and client status. This can be done via the CLI or webUI.
Monitoring Via the CLI
These CLI commands are used to monitor the network and clients:
show interface dsl status
pay attention to the SNR Margin number. It should always be 6dB or above
pay attention to the Quality parameter. This measures bit errors
show interface wireless status
if the WLANs and radios are configured correctly, the radios operational status
will show “up”
show wifi client statistics
This command displays a top level view of the connected wireless clients. To
display details, enter the client MAC address and its connected radio. The
webUI is much easier to use when monitoring connected clients
Monitoring Via the webUI
The webUI is much easier to use when monitoring wireless client statistics.
Monitor Tab – Status
This screen displays a color-coded map of
every dsl and Ethernet port the dsl line status
and remote Ethernet port status. Click the +
sign next to the port to display additional line
parameters. Pay close attention to these
important parameters:
Quality
Quality is a measure of bit errors. If the
quality becomes ‘fair’, check the SNR
Margin.
SNR Margin
Margin is directly related to quality. Margin
should always be 6dB or greater. If Quality
shows fair, raise the SNR Margin target to
9dB or lower the target line rate in the
