1 Overview The MobileAccessVE Dual-Band solution provides enhanced, cost effective, in-building 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.
Overview 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. Figure 1-2. Multi-Tier VE Installation 1.
Overview 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. The following figure shows the Multi-tier Dual-Band VE solution architecture. Figure 1-3. VE Multi-Tier Basic Architecture The Master VCU distributes the wireless services from the service provider’s equipment to the Slave VCUs.
Overview 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 1.2.1.1 VCU Front Panel The front panel supports the interfaces to the wireless services (two services – corresponding to the two supported bands) and includes interfaces to VAPs or Slave VCUs (depending on the configuration).
Overview The following provides a description of the front panel LEDs.
Overview 1.2.1.2 VCU Rear Panel The rear panel includes the following: power switch, AC input, AUX alarms, and service personnel connections. Console connector AUX Alarms Figure 1-5.

Overview 1.2.2 VE Access Pod (VAP) Each VAP provides the following functions: Antennas – distributes the wireless services signals. The antennas are internal, where external (optional) antennas can also be connected. Connection to Ethernet port – relevant when connected to jacks that provide an Ethernet connection to a user terminal. The VAP can be mounted/hung on the wall or placed on a flat surface (such as a desk). The following figure shows the desktop VAP.
Overview The following figure shows the desktop VAP rear side and the underside view with the CAT-5e/6 patch-cord cable. RJ-45 Connector to VCU Figure 1-7. VE Access Pod-Rear 1.2.2.1 RJ-45 Connector to LAN terminal (e.g. computer) VAP Antenna Options Two antenna options are available for VAPs: Integral internal antennas Connectors that interfaces to external antennas for special coverage requirements. Note: By default, the VAP is set to transmit through the integrated internal antennas.
Overview 1.3 System Monitoring and Management The MobileAccessVE system (Master VCU, Slave VCUs, and VAPs) is centrally managed via a single Web connection to the Master VCU. The basic screen in the GUI is the Config tab, which enables the user to view the system topology and setup parameters, Control Units, and all Access Pods connected to the Control Units. Note: When locally connecting to a specific Slave VCU, only the VAPs connected to this VCU can be monitored.
Installation Workflow 2 Installation Workflow The following figure summarizes the main steps of the installation procedure: Installation Workflow 1. Infrastructure Preparation 2. Installation Procedure Plan the floor coverage and VAP locations according to the type/density of the site. Install the Master VCU in the IDF/telco shaft. Check that Ethernet jacks are available in all planned VAP locations.
Infrastructure Requirements and Layout Planning 3 Infrastructure Requirements and Layout Planning 3.1 General information on Location 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.
Infrastructure Requirements and Layout Planning 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).
Infrastructure Requirements and Layout Planning 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.
Infrastructure Requirements and Layout Planning 3.3.1.1 Standard Environment A traditional office environment with offices, hallways and scattered cubicles. Table 5: Standard Environment Installation Distances Band PCS PCS UMTS Technology CDMA or GSM WCDMA WCDMA Downlink Frequency 1900 MHz 1900 MHz 2100 MHz Signal Propagation from VAP 67 feet (20.5 m) 64 feet (19.5 m) 57.5 feet (17.
Infrastructure Requirements and Layout Planning 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.).
Infrastructure Requirements and Layout Planning 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: Figure 3-2.
Infrastructure Requirements and Layout Planning Notes: The red VAP coverage circles have an approximate radius of 45, 60 and 70 foot (14, 18 and 21 meters) for the small, medium and large circles respectively. Diagram is drawn according to the guidelines for UMTS service, 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.
VCU Unit Installation and Provisioning 4 VCU Unit Installation and Provisioning This section describes the installation and configuration procedures for VE Control Units (VCU) located on each floor. These should be performed only after planning the floor coverage and installation locations, as described in the previous sections.
VCU Unit Installation and Provisioning 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.
VCU Unit Installation and Provisioning 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. Note: If only one alarm is required (Minor or Major) an external connection of a wire jumper between pins 8 and 13 is necessary (normally closed). Connect the relevant alarms according to the connector pinout below. 15 11 Major Alarm 8 7 12 Minor Alarm 13 Table 9.
