  • Page 10: Introduction

    1.0 Introduction The Nortel Digital Mobility Deployment Tool serves two purposes as a site deployment and a sales demonstration tool for the Nortel Digital Mobility Solution. Using the tool for demonstration purposes the kit can be operated independently of any Nortel system in order to demonstrate the mobility capability, overall radio signal propagation of the base station and handset features.

  • Page 11: Hardware Identification

    2.0 Hardware Identification 2.1 Deployment Base Station The Deployment Base Station is only for use of deploying the Nortel Digital Mobility Solutions. The Deployment Base Station provides 2 speech channels and supports a maximum of one handset-to-handset conversation. In the event a technician wishes to perform a deployment alone, the Deployment Base Station supports the connection of an alternative audio source.

  • Page 12: Rechargeable Base Station Battery Pack

    2.3 Deployment Handset Provided in the Digital Mobility Deployment Kit are one (1) 7430 handset and one (1) 7440 handset, charger bases for each handset, and a power supply for each charger base. The handsets have been subscribed to the Deployment Base from the factory and are identified as handsets #1 and handset #2.

  • Page 14: Radio Coverage Properties

    3.0 Radio Coverage Properties The deployment of Base Stations and Repeaters is a critical aspect of the Digital Mobility solution. If the Digital Mobility Controller installation is to be successful, the deployment concepts explained here must be followed. To determine the permanent installation location of Base Stations within a given installation, a deployment survey must be taken to discover the optimal location and total quantity of Base Stations required for the installation.

  • Page 15: Horizontal And Vertical Overlap

    3.2 Horizontal and Vertical Overlap Base Stations are omni-directional; meaning RF signal is propagated vertically and horizontally from the Base Stations and Repeaters. Depending on building materials the Base Station coverage area will typically extend to more than one floor of a structure. In the multi-zone building installation below, the coverage areas overlap horizontally, allowing the handset to roam the structure without interruption.

    Example: 1.9 GHz - USA 16 Channels. 8 Channels. 8 Channels. Distance > 25 metres (Free sight) Example: 2.4 GHz 24 Channels. 12 Channels. 12 Channels. Distance > 80 feet/25 metres (Line of sight) 3.4 Signal Performance Measurement 3.4.1 Q Value The Q-value is an expression for the bit failure rate in the communication between the Base Stations and the handset.
  • Page 17 3.4.2 RSSI The Radio Signal Strength Indicator value is a relative expression for the field strength of signal from the Base Station. The RSSI-value is used for the choice of the alternative Base Station(s). The wireless handsets will choose the Base Station from which the strongest RSSI signal is received as the first alternative Base Station.
  • Page 18 Below given values are only to be used as a guideline in a situation where no reflections from surroundings are present and where there is no interference from other equipment. 3.4.4 Impact of Environmental Items on Radio Coverage Different weather conditions can have an influence regarding radio coverage. For example, a wet roof or wall can act as a shield.
  • Page 19 3.4.6 Signal Meter Display During a Deployment Survey, the wireless handset is used as a tool for determining the optimal location for Base Stations and Repeaters. Radio coverage is measured by a combination of the Q-value and RSSI values. Handsets measure the signal of the active base station from which the handset is receiving signal while off hook and up to three additional alternate base stations.

  • Page 20: Deployment Techniques

    A Handset User’s Guide is included with each handset in the Digital Mobility Deployment Kit Please refer to the guide for specific information regarding the basic functions of the 7430/7440 Deployment Handset. It is strongly recommended to read this guide before continuing.

  • Page 21: Using The External Audio Source

    While viewing the signal meter on the display of the handset and listening to the sound quality through a headset, it is also important to simulate the influence of the human body when using the handset. To simulate this, place your free hand around the back of the handset and cup the upper third of the handset with your palm.

    5.0 Deployment Procedure Begin the deployment survey by interviewing the customer representative familiar with the full expectation of coverage and performance of the Digital Mobility solution. During this conversation, collect the following documents and information: • Site blueprints / maps •...

  • Page 24: Documenting Radio Requirements And Results

    5.2 Documenting Radio Requirements and Results If an agreement is made with the customer to accept areas where radio coverage is less then acceptable, this should be documented and agreed upon with the customer. Note the results of the Deployment Survey on the relevant floor plan documents. Clearly document the location of the Deployment Base Station and the expected mounting location of the permanent Base Station or Repeater and the coverage area provided from this location.
  • Page 25 2. Place the Deployment Base Station in position 1 at a height of 6 to 8 feet/1,8-2,5m. 3. Measure the signal in a 45 degree angle towards the center of the area. Document the boundary of the signal. 4. Proceed to point 2 and perform the same test. Document the boundary of the signal. 5.

  • Page 26: Surveying A Multi-Level Location

    5.4 Surveying a Multi-level Location There are 2 ways to approach the survey of a multiple story site Survey each floor as individual parts Place the Deployment Base Station on one floor and continue the measurement of coverage on adjacent floors. When surveying each floor as individual parts, the excess radio signal propagated between floors is considered used for high density traffic.

    6.0 Kit Maintenance 6.1 Subscription The handsets are subscribed to the base station from the factory. If the handsets are unsubscribed then a subscription is required. Once a handset is subscribed to the Deployment Base the registration information will be stored in the Deployment Base and the handset memory. In order to prepare the base station for handset subscription power up the base station and remove the base station cover.
