CDS – Cellular Distribution System

Improves cellular services in small to medium sized buildings.

Works for 800-900 MHz and 1900 MHz frequency bands

Easy to install 2U rack mount panel

Uses either RG6 (800-900MHz) or LMR400 (1900 MHz) low loss cables

New OCC Product Overview
cds overview
CDS Overview
  • Provides improved cellular communications to buildings of poor service, where good service is available outside the building.
  • Applies structured cabling concepts to support wireless communications.
  • Uses Distributed Antenna Technology.
  • Voice, Data and 3G supported services.

Broadband Antenna
  • Suitable for both 800-900 MHz and 1900 MHz applications.
  • Uses RF N-connector
  • Easily mountable in ceiling tile environment
what is a distributed antenna
What is a Distributed Antenna
  • Distributed Antennas Systems (DAS) use multiple antennas for a single radio.
  • DAS offer a distinct advantage of creating low loss signal pathways at specified locations.
  • Heavy Loss materials (metal walls, re-bar concrete) can be by-passed.
  • The 4 outputs from the CDS Panel and the faceplates are a distributed antenna.
cds architecture
CDS Architecture
  • External Antenna (Omni directional or high gain).
  • Cable to the panel from the extern (low loss coaxial cable – 5 dB).
  • Panel with bi-directional signal booster (65 dB Gain (37.5 Uplink and 37.5 Downlink channels)
  • Coaxial cable to the faceplate. (30 dB Loss)
  • Faceplate antenna (Omni directional)
install considerations
Install Considerations
  • Available Power Outside is proportional to Maximum Power Inside.
  • Multiple providers may share frequency band
  • Lower loss cable translates into increased coverage range.
  • Antennas are frequency dependent.
cds install criteria
CDS Install Criteria
  • Cell Phone Coverage must be good at a locale where the external antenna can be placed.
  • CDS Panel must support one of the approved service providers.
  • May determine frequency band from your service provider in your region www.wirelessadvisor.com
cds supported technologies
There are 3 Service Provider Bands in North America

824 – 896 MHz (Verizon, AT&T) CDMA

806 and 900 MHz (Nextel, Southern Link) TDMA

1840 – 1990 MHz (PCS providers)

Supports voice and data communications, as well as 3G phones (AT&T verified)

CDS Supported Technologies
3 step installation smp cds
3 Step Installation SMP CDS?
  • SMP CDS offers several distinct benefits:
    • Place the external antenna at an outside location with good service.
    • Install the internal antennas in proximity to areas where service is deficient.
    • Provide 120AC to the panel.

CDS Silver Spring Beta Test Site
  • Installed in Silver Spring, MD area.
  • 800-900 MHz Verizon and AT&T support.
  • Basement fill-in operational requirement in a 3 story building.
  • Installed October 2008
  • 7 Story building currently being cabled for CDS installation at new facility next door.
