LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 1 1 Overview The MobileAccessVE LTE 700 MHz MIMO solution provides enhanced, cost effective, in-building LTE MIMO coverage for any small to large-sized enterprise environment. This solution is quickly and easily deployed using the existing Ethernet cabling infrastructure without affecting existing LAN services or performance. The MobileAccessVE solution distributes LTE MIMO service to VE Access Pods (VAPs) installed throughout the enterprise and which distribute the services via integrated internal antennas (or optional external antennas), and provide Ethernet connectivity (and PoE pass-through) to LAN terminals. VE seamlessly coexists with the Enterprise LAN and does not consume LAN capacity. The VAPs are distributed on each floor and plug into existing standard Ethernet jacks. They are powered via PoE technology and managed via a VE Control Unit (VCU) located in the floor’s telco closet. For site coverage that requires more than one VCU, several VCUs can be aggregated under a single Master VCU. The Master VCU provides the interface to the carrier’s capacity sources and management. This enhanced LTE 700 MIMO coverage solution can be quickly and easily installed with minimal disturbance to the enterprise. In less than a few hours and with no additional cables being 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 both the service provider’s equipment and the Ethernet switch, and distributes Ethernet and mobile services to up to 12 VAPs distributed over one more adjacent floors. Figure 1-1. Single-Tier VE Installation Multi-tier installation includes the Master VCU that supports up to 12 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.
Overview LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 2 Figure 1-2. Multi-Tier VE Installation 1.1 System Architecture Main Elements - The MobileAccessVE solution is based on the following main elements:  VE Control Unit (VCU) – The control Unit can serve as either 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 automatically 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 Telco closet, interfaces to the service provider’s RF capacity sources, and provides secure, central management to up to twelve VCUs, as well as all connected VAPs. In cases where no Slave VCUs are required, VAPs can be connected directly to the Master VCU.  Slave VE Control Unit (Slave VCU) – installed in the telco/IDF closet and used to expand coverage to additional floors. Each VCU interfaces the Master VCU and up to twelve VE Access Pods and twelve Ethernet connections. The Slave VCUs distribute wireless service signals to each VAP along with PoE and (where relevant) 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 7 cables.  VE Access Pod (VAP) – These are pluggable antennas distributed at strategic locations over one or more floors to provide maximum coverage. VAPs provide RF coverage via integrated, internal antennas. VAPs are also equipped with an interface for external antennas for special coverage requirements. VAPs are remotely powered from the VCU using Power over Ethernet (PoE), eliminating the need for local powering. 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, consult with MobileAccess support.
Overview LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 3 The following figure shows the Multi-tier VE LTE 700 MHz MIMO solution architecture. Figure 1-3. VE Multi-Tier Basic Architecture The Master VCU distributes the wireless MIMO services from the service provider’s equipment to the Slave VCUs. At the Slave VCUs, the wireless MIMO services are converged with Ethernet service and routed to the VAPs via the Ethernet LAN CAT-5e/6 cabling infrastructure. The VAPs distribute the wireless LTE MIMO service via integrated internal antennas or (optional) external antennas and provide Ethernet/IP connectivity (and PoE pass-through) to the connected appliances such as WiFi APs and IP Phones. 1.2 System Elements This chapter describes the interfaces of the VE Control Units and Access Pods. 1.2.1 VE Control Unit (VCU) Capabilities and interfaces The VE Control Unit can operate as a Master VCU, managing up to twelve VCUs, or as a Slave VCU connected to up to twelve VAPs. While operating as a Master VCU:  Interfaces to RF source(s) and to VCUs  Converges Wireless services and distribution to Slave VCUs  Slave VCUs and VAP management and control  Remote management of the entire deployment While operating as a Slave VCU:  Interfaces to Master VCU  Converges Wireless services, Ethernet and PoE and interfaces to VAPs  Management and control of connected VAPs

Connection to existing Ethernet jack (and external antenna if required).  VAP power source - No power connections required. VAPs are power fed from VCU using PoE (Power over Ethernet) technology. Figure 3-1. VE Multi-Tier Basic Architecture
Infrastructure Requirements and Layout Planning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 12 3.2 Infrastructure Requirements Ethernet standards specify that the maximum distance between an Ethernet switch and an appliance (computer, WLAN AP etc) should not exceed 100m (300ft). Therefore, when VE shares the IT LAN, the maximum distance for a given cable run cannot be longer than 100m (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). 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, should adhere to the CAT-5e/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 or more VCUs depending on the number and locations of the installed VCUs: (48.3cm x 51.3cm x 8.88cm) per VCU. Note: When planning the IDF/telco shaft, take the RF equipment (picocell/microcell or BDA) and the VCU into consideration. 2. 350 Watts of AC power to the VCU IDF/Telco closet. 3. Building infrastructure:  CAT-5e/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 no shorter than 10m (33ft).  CAT-5e/6 STP cable from VCU to each VAP with run lengths NOT exceeding 100m (300ft) and no 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 can support the VE installation. If available, review the infrastructure documentation to determine cable types and lengths. If the infrastructure documentation 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 x D-Type 9 pins RS-232 interface for local craft
Infrastructure Requirements and Layout Planning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 13 3.3 Coverage and Installation Planning Note: The following section provides 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 maximal coverage area of each VAP is affected by the density and type of environment being covered. Therefore, it is recommended to determine the location in two phases:  Plan the ideal location of each VAP in order to achieve complete coverage of the floor.  Select the exact location according to the location feasibility, where each VAP unit may be wall or desk mounted and an option for an external antenna is available. The supplied services (wireless only or Ethernet and wireless) 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 wireless service. For more information see section 4.3.1.  If the jack is not currently active (not connected to an Ethernet switch), the VAP will distribute only the wireless services. This section provides information on coverage criteria in various types of environments (Open, Standard, Dense and Merged) and provides rules-of-thumb for various installations of the VAPs. Note: Section 3.4 provides a detailed example of installation planning in various types of environment. It is recommended to review this example after reading this section. 3.3.1 Types of Environments This section describes the different types of installation environments and provides guidelines 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”.

Table 6: Open Environment Installation Distances Signal Propagation from VAP 64 feet (21 m) Recommend spacing between VAPs 128 feet (42 m) Recommended maximum distance of VAPs from outer walls 64 feet (21 m) Coverage area per VAP 12,750 sqft (1,185 sqm) 3.3.1.3 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 include dense offices, hospitals, and manufacturing spaces. Table 7: Dense 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) 3.3.1.4 Combination of Environments In areas with a combination of environments, place VAPs on the border between the different environment types slightly 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 3.4.3.). To ensure maximal coverage, VAPs can be re-located or added. If a coverage gap is detected, the VAPs can be re-located until coverage gaps are filled.
Infrastructure Requirements and Layout Planning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 15 3.4 Planning VAP Layout The following section describes the steps of planning VAPs along the covered floor. At the end of this section an example of a planning map is provided. Note: It is highly recommended to use a floor plan when planning the VAPs locations. 3.4.1 RF Coverage Factors It is important to note the type of factors that can severely impact RF coverage, and should be avoided:  Metallic Structures such as elevators, high file cabinets, and some moveable metallic partitions severely degrade RF signals. 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, as well as bathroom fixtures typically have fairly high signal attenuation and should be considered as dense spaces.  Types of Glass that have metallic coatings can affect RF coverage, typically exterior or mirrored. However this issue is not normally encountered inside a building. 3.4.2 Mapping Locations To map the VAP Locations 1. Map out the available Ethernet jack locations and mark all CAT-5e/6 drop 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 section 3.4.3), mark approximately where you would like to place each VAP in the facility. VAPs may be added (or removed) at anytime for optimal coverage. 3. For each jack being used to connect a VAP, check if the jack is already connected to the Ethernet switch. . 4. Connect the Ethernet cables corresponding to the selected jacks according to section 4.3.1. 5. It is also recommended to check the area where each VAP will be installed to ensure the installation is feasible. 3.4.3 Optional Directional Antennas Each VAP has an integrated internal antenna that provides isotropic radiation. To prevent interference and improve coverage, connect directional antennas to VAPs installed near outer walls. The VAP antenna parameter must be set accordingly via the Web GUI – see 8.3. 3.4.4 Installation Plan Example The Following figure shows a floor plan map with all required marks:
Infrastructure Requirements and Layout Planning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 16 Figure 3-2. Floor Plan Example Notes:  The red VAP coverage circles have an approximate radius of 41, 56 and 64 foot (13.5, 19 and 21 meters) for the small, medium and large circles respectively (drew according to the guidelines given in section 3.3.1.  VAP 3 is surrounded by the bathroom and stairwell which are considered dense objects and 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 in an Open Environment.  VAPs 11 and 13 are placed closer to the offices to provide better coverage to them, but on the open side will actually cover a much greater area. This is why the coverage is larger and shown here more as an oval than a circle.  The area between VAPs 7 and 14 would probably be the lowest coverage spot in the building because of the bathrooms and stairwell on either side. If after the system is 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. The following figure depicts an actual measured quantified coverage of a floor area planned according to the above rules.

Power on the signal sources.
VCU Unit Installation and Provisioning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 19 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). After connecting the capacity source, if the LED remains RED verify that the Max Expected Pin is configured properly and service is enabled. 4. Connect the Master VCU VAP ports to the Slave VCUs VCU/VCH ports via the patch-panel that feeds the dedicated CAT-6/7 cabling system. NOTE: After the Slave VCUs are connected (according to section 4 ), verify that that the Master VCU VAP Status LEDs which correspond to the connected Slave VCUs complete initialization (blinking light) and show a solid green light. 4.2 Auxiliary Connections The auxiliary connections are performed through the Master VCU rear panel Alarms port. See following figure. 4.2.1 Alarm Output Connections The controller can provide Major and Minor Output Alarms. These alarms can be connected directly to either the auxiliary input of the Base Station or to any additional dry-contact application. A Major Alarm is generated when there is an alarm condition in one or more VCUs, while a Minor Alarm is generated when there is an alarm condition in one or more of the VAPs.

VCU Unit Installation and Provisioning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 22 4.3.1 Connections of VAP Ethernet Cables For VAPs installed on currently ACTIVE Ethernet ports, shift the relevant Ethernet LAN connections as follows.
VCU Unit Installation and Provisioning LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 23 For VAPs installed on currently INACTIVE Ethernet ports, connect as follows. NOTE: After the Slave VCUs are installed and connected to the correct ports in the patch panels, please proceed with the VAP installation as described in chapter 5 . However, it is recommended to complete the VCU provisioning first (see section 4.3.2) because when installing the VAPs they will instantly provide the wireless service (and the installer will be able to check the coverage). 4.3.2 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 specifically 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 infrastructures that use either 802.3af PoE or 802.3at PoE. In the current release MobileAccessVE supports operation with “alternative a” PoE. Note: Future enhancements will support coexistence with “alternative b” PoE. If this is currently required, consult MobileAccess.

Troubleshooting LTE 700 MHz MobileAccessVE Instant Coverage Solution User Manual 69 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 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 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.
