Preliminary Analysis

preliminary analysis

Before beginning, NF performs a basic analysis to determine: What services are required? Which cell carriers are used? Is Wi-Fi service needed? In addition to this profile, a detailed floor plan of the site is necessary to estimate the required system.

 

 

 

 

 

 

 

Site Survey

site survey

A site survey is performed to characterize signal propagation within the building, investigate donor signal options and to determine equipment space and cable routing issues. The survey is performed by way of numerous analyses.

A receiver and mapping software is used to record dominant channel/carrier/PN received signal strength for single or multiple wireless service providers at various locations within the building. This helps to determine potential donor sites and repeater requirements. Potential donor signals are also investigated at the roof level, for neutral host opportunities that may not require dedicated base stations.

  • Wireless capability to handle high traffic areas such as conference rooms and business centers.
  • Spectrum snapshots are taken for each wireless service provider’s bandwidth at all potential donor antenna locations. This is used to identify repeater bandwidth, gain, and power requirements, and pinpoint potential interference issues for early intervention.
  • Transmitter tests are used in applicable environments to verify paths in complex inbuilding wireless applications.
  • Building materials, configuration, and existing wiring are analyzed to help design a system that requires minimal construction and rewiring, and documentation is done on variations in client RF environments. Equipment that holds potential interference, such as metal racks, concrete walls, etc. are taken into account.

Building codes and client safety requirements are documented and closely followed, as they are unique to each setting and situation. For example, most hospitals require plenum rated cable to be used rather than standard coaxial cable which significantly affects cost. Common safety features that are followed include cable fire ratings, safety training, safety equipment, and union labor.

 

 

System Design / Proposal

system design

Our engineers provide a detailed proposal including itemized system components and their costs. Alternatives and possible modifications are presented in a clear and user-friendly format. Proposal includes financing options as well.

 

NF projects are based on a core methodology of disciplined schedules with initiation, planning, execution, control, and closure. Each step is fully completed before moving on, ensuring a wireless solution that is solidly built from the ground up.

  • Development of a link-budget analysis for multiple wireless technologies for both coaxial cable and fiber optic systems, with an accounting of all losses and gains in the RF In-Building System for each distribution antenna. The system design also ensures that the uplink and downlink RF paths are balanced.
  • The equipment for In building wireless systems are selected according to coverage requirements, RF link budget specifications, and customer aesthetic needs. These include coaxial or fiber optic cable, repeaters, fiber equipment, distribution antennas, and splitters, connectors, etc.
  • Perhaps the most vital element in the wireless network plan is a detailed and specific design drawing. NF drawings are accurately portrayed to depict equipment placement, with detailed installation instructions and link budget analyses for each antenna. Hard and soft copies of drawings are available.

Installation

Installation

Upon approval, NF‘s own technicians will install all necessary DAS equipment, from antennae and bi-directional amplifiers to wiring, repeater systems, and multi-service fiber distributed antenna systems.

 

 

 

  • NF installers are prepared to travel nationwide in order to ensure that installation of a wireless system is done in-house by experienced technicians.
  • During installation, technicians ensure that the cable complies with TIA/ISO standards, using Optical Time Domain Reflectometers and Cable Sweep Analyzers to identify and eliminate deficiencies.
  • Technicians meticulously document all critical DAS data during installation. This is used for future maintenance and repairs. Some of the details include repeater attenuation settings, cable labeling schema, coaxial cable sweep measurements, fiber optic cable OTDR results, and other necessary technical information.

 

Maintenance

maintenance

While NF distributed antenna systems are generally maintenance-free, a one-year service contract is provided, free of charge, with installation. If required, our technicians perform rigorous, regularly scheduled preventive maintenance inspections. We also offer repair and response programs tailored to fit the needs of the client.

  • Maintenance site visits include an annual preventive maintenance routine and full assessment report. This includes cable and fiber testing, equipment inventory reports, system diagnostics, and other analyses.
  • System monitoring of select systems is done by way of a broadband wireless network router installed by NF. Major or minor SNMP traps are reported to the NF technical team. Other monitoring options are available, such as initial alarm notification, remote diagnostic status, and progress reports during each step of the repair.
  • A service level agreement is provided with each NF DAS system, providing support for the client’s wireless network.
  • Aside for the manufacturer’s warranty, Near Future offers a one-year warranty on all in-building wireless systems, as well as additional warranties, as needed.
