MobileAccessVE WiMAX Instant Coverage Solution User Manual 1 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 single-tier and multi-tier VE installations. 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. Figure 1-1. Single Tier MobileAccessVE Installation
System Architecture 2 MobileAccessVE WiMAX Instant Coverage Solution User Manual 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) – These are pluggable antennas distributed at strategic locations on 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.
Overview MobileAccessVE WiMAX Instant Coverage Solution User Manual 3 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). 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.

Overview of the Installation Procedure 12 MobileAccessVE WiMAX Instant Coverage Solution User Manual 2 Infrastructure Requirements and Layout Planning The following figure shows the flow for the infrastructure preparation.
Infrastructure Requirements and Layout Planning MobileAccessVE WiMAX Instant Coverage Solution User Manual 13 2.1 Summary of Unit Locations and Connections  Service provider’s RF equipment - Macrocell, Microcell, Picocell, Femtocell, BDA, etc. connects to the VCU through a passive interface.  VCUs:  Master VCU installed at the main IDF/telco cabinet and connected to all VCUs.  Slave VCUs installed at the IDF/telco cabinet of each covered floor and connected to the Master VCU, the Ethernet switch and the VAPs (through the cabling patch panel).  WiMAX service signals from Master VCU to VCUs – routed through dedicated Ethernet CAT-6 or CAT-7 cabling.  WiMAX service signals from VCUs to the VAPs – routed through existing Ethernet CAT-5e/6 cabling infrastructure.  VAP location and mounting - wall-mounting or desktop-mounting. Connection to existing Ethernet jack (and external antenna if required).  VAP power source - No power connections required. VAPs are power fed from the VCU using PoE (Power over Ethernet) technology. 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).
Infrastructure Requirements 14 MobileAccessVE WiMAX Instant Coverage Solution User Manual 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. 4. Master VCU Cable Connections:  2 x N-type female, 50 ohm interfaces to carrier equipment  Up to 12 x RJ-45 interfaces to Slave VCUs  1 x RJ-45 interface to Management  1 x D-Type 9 pins RS-232 interface for local craft  1 x D-Type 15 pins interface for External Alarms (dry contacts) 5. Slave VCU Cable Connections  1 x RJ-45 interface to Master VCU (not used in small single tier deployments)  12 x RJ-45 interfaces to VAPs  12 x RJ-45 interfaces to Ethernet Switch for LAN service  (1) RJ-45 connector for switch bypass  1 x D-Type 9 pins RS-232 interface for local craft
Infrastructure Requirements and Layout Planning MobileAccessVE WiMAX Instant Coverage Solution User Manual 15 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 ideal location of each VAP in order to achieve complete WiMAX coverage of the floor and then  Select exact location according to the location feasibility, where each VAP unit may be 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”.
Coverage and Installation Planning 16 MobileAccessVE WiMAX Instant Coverage Solution User Manual 2.3.1.1 Open environment 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.

Examples for this type of environment are dense offices, hospitals and manufacturing spaces. Table 2-3: Standard Environment Installation Distances Signal Propagation from VAP 41 feet (13.5 m) Recommended Spacing between VAPs 82 feet (27 m) Recommended Maximum distance of VAPs from outer walls 41 feet (13.5 m) Coverage area per VAP 5,300 sqft (495 sqm) 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 provide coverage through the office walls. (See VAPs 11 and 13 in the floor plan map in section 2.4.3.) 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.
Infrastructure Requirements and Layout Planning MobileAccessVE WiMAX Instant Coverage Solution User Manual 17 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. 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.
Planning VAP Layout 18 MobileAccessVE WiMAX Instant Coverage Solution User Manual 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.

Installing Slave VCU 26 MobileAccessVE WiMAX Instant Coverage Solution User Manual 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.

VE Connections in Central Ethernet Source Topologies 70 MobileAccessVE WiMAX Instant Coverage Solution User Manual 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.
