  • 1. MC-802 Wireless WallPlate Field EvaluationThe Motorola MC-802 Wireless WallPlate is designed for multi-tenant buildingssuch as hotels, healthcare, apartments, and dormitory housing. The principal goalis to leverage the in-building telephone wiring to deploy Ethernet and wireless LANnetworks without the effort and expense of re-wiring with structured cabling. MC-802 is part of the T3 PowerBroadband product family. The T3 system combinesproven VDSL with patented Adaptive Line Power to produce a truly unique, highvalue product.Although designed primarily for hotels, the T3 PowerBroadband system can bedeployed in many multi-tenant applications.When evaluating the T3 PowerBroadband system with the MC-802 WirelessWallPlate, 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 materialand personal support, please contact Motorola PBN Customer Support at the numbers listed inthe appendix.Daran HermansMotorola Product ManagerDID +1 925 201 4510MBL +1 925 250 1467EML dhermans@motorola.comMotorola, Inc Page 1 of 12

  • 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. Motorola, Inc Page 3 of 12
  • 4. Measure the Received signal level in each adjacent roomFind 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 5rooms. You could also use 6 rooms without trouble. This will provide a -72dBm signal or betterin each room of the hotel with little co-channel interference. 5 rooms coverage per WP AP A P -48 -65 -72 -80 -88 -92 Delta (dB) 17 7 8 8 4C o - C h a n n el I n t er fe r en c eWith the WP installed in the site survey room, continue measuring RF signal strength in roomsacross 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, itcan 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-overlappingchannels. 5 rooms Rm100 Rm110 1 -70 11 -70 HALLWAY HALLWAY -70 6 -70 1 Rm107 Rm117Motorola, Inc Page 4 of 12
  • 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.

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 Motorola, Inc Page 5 of 12
  • 6. I n s t al l t h e C r o s s C o n n e c t sIdentify the line 1 wire pair. The recommended procedure is to begin replacing cross connects atthe room termination block, moving back to the PBX termination block. The reason is simple: Inmost cases, the room termination blocks are marked with room numbers; whereas the PBX blockis marked with cable pairs or PBX port IDs. 2 2 3 1 1. Install the Cross-Connect block on the wall 2. Connect the RJ21 cables to the T3 Switch 3. Remove and replace each line 1 wire following this procedure: 1 • Starting at the Room block, remove the “old” wire termination • (leave the “old” wire attached to the PBX block until step 3) • Punch down a new wire on the same termination point • Route the new wire to the cross connect block, punch down on the right side 2 • Mark the block with the room number • Punch down a new wire pair on the left side of the block 3 • Route the new wire pair to the PBX block • At the PBX block, remove the “old” wire termination from step 1 • Remove the “old” wire and punch down the new wire on the same terminationMotorola, Inc Page 6 of 12

  • 8. I n s t all I n - l i n e f il t e r s a n d W a l l P l at e sThe Wireless WallPlate has a built-in POTS and Line Power filter for the desk phone. Install anin-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 withEN60950 requirements. Use a small flat blade screwdriver to lift the tab if attempting to removethe filter.If installing a filter on a bathroom phone, use the Unterminated filter. Remove the bathroom wallplate and terminate the filter in the wall box using wire beans.

  • 10. M o n i t o r i n g t h e N et w o r kFollowing the above steps is useful in demonstration or evaluation of the installation and RFsignal propagation. During installation, and follow-up evaluation, the system should be monitoredto check for network and client status. This can be done via the CLI or webUI.Monitoring Via the CLIThese 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 clientsMonitoring Via the webUIThe webUI is much easier to use when monitoring wireless client statistics.Monitor Tab – StatusThis screen displays a color-coded map ofevery dsl and Ethernet port the dsl line statusand remote Ethernet port status. Click the +sign next to the port to display additional lineparameters. Pay close attention to theseimportant parameters:QualityQuality is a measure of bit errors. If thequality becomes ‘fair’, check the SNRMargin.SNR MarginMargin is directly related to quality. Marginshould always be 6dB or greater. If Qualityshows fair, raise the SNR Margin target to9dB or lower the target line rate in theInterface Tab - DSLMotorola, Inc Page 10 of 12
