CELLULAR DISTRIBUTION SYSTEM

Transcription

1 Overview OCC s patented Cellular Distribution System (CDS) is a wireless enhancement product designed to resolve low cellular signal strength issues for in-building applications. Designed as a complete kit, the CDS system provides everything you need to mitigate your 4G communications dead zones, while also supporting legacy 2G and 3G services with a simplistic hardware approach in a standard rack mount form factor. The system is based on a donor antenna architecture, whereby an antenna is placed at an external location to capture the available signal from the provider s tower, deliver it to a rackmounted system below which boosts the signal strength and then rebroadcasts it throughout the building where internal antennas are placed. The CDS system offers several distinct advantages: The CDS system is a simple, cost effective solution compared to high end DAS systems for area specific coverage enhancement, requiring no software configuration and minimal adjustment at installation. The low power 3W unit does not require carrier approval and supports all providers with good signal strength available where the donor antenna is placed. A dedicated OCC technical support team available to assist in designing and planning your in building enhancement system. A complete solution, with all hardware including head end, antennas, protection and cable assemblies designed to work optimally together. Applications: Manufacturing buildings Office facilities Retail stores Metal building structures Campus dorms Building basements and below surface structures Hospital departments Parking structures In order to simplify the installation, preterminated and tested cable plenum and riser assemblies can be ordered to length or low loss bulk cable and connectors are available. *Dependant on outdoor signal and antenna cable lengths.

2 CELLULAR DISTRIBUTION SYSTEM Applications A common building showing how the rear of the building is shadowed from a provider tower, reducing signal strength at the back side of the building. A CDS system installed in the facility shows how the signal captured by the external donor antenna is the transported throughout the building. Is CDS suitable for your building? Though every building is a unique propagation environment, there are several signs that the OCC CDS is a good fit for resolving your in-building wireless coverage issues: 1. Your mobile device works well outside your building, but once you walk inside you cannot continue your conversation. 2. Mobile devices work well near a window, but seem to lose service once you move to the center of the building. 3. Cell service is good on upper floors, but degrades on lower floors and in basement. 4. Measured signal strength for pertinent providers outside the structure is greater than -70 dbm. CDS is designed to be easy to install and configure. OCC s expertise and experience in resolving in-building wireless coverage problems can make missed calls and poor data rates a thing of the past. Practical considerations of a CDS installation The CDS system is a wireless enhancement system, creating signal paths between mobile users located inside a building to the clear carrier signal outside of the building, through an externally mounted donor antenna. The functional objective of the system to provide a transmission pathway for users under the CDS footprint to the rooftop. However, each building is unique, and installations are often non-ideal. Some practical considerations when installing a CDS system to ensure effective operation include: 1. Isolation of internal antennas and the external antenna. To ensure the system does not create a feedback noise situation, thus causing the unit to shut down, physical separation of antennas should be maintained. Avoid mounting internal antennas close to windows Outside Antenna in close proximity to the donor antenna on the roof, and for facilities that require multiple CDS systems, maintain 100 feet of separation of between donor antennas for two separate CDS installations in the same building. If you have an exceptional signal Inside Antenna strength at the outdoor antenna location, it may be feasible to run longer cable lengths, both from the external antenna to the CDS unit, and from the CDS unit to the internal antennas. Please contact OCC for technical assistance. 2. Cable lengths are limited by attenuation, not by a specific maximum length. If a long length is required, OCC can supply a less lossy cable that can be used to compensate for extended lengths. 3. For regions where a weak provider signal exists, on the order of -85 dbm, a high gain antenna can be used to enhance service to a single tower, however this may in turn worsen signal strength to other towers by the directivity often characteristic of high gain antennas. If this is required, an additional donor antenna may be required. 4. OCC can assist in all aspects of system design. Our experience in cellular system configuration can be used to design a system based upon your unique environment. 2 OCCFIBER.COM

3 Installation Overview Indoor Antenna CDS Panel A sample CDS Installation overview CDS location and internal antenna cabling plan for a mixed manufacturing and office facility CDS is designed for general applications to be easy to install. The base kit contains a donor antenna (with mounting kit hardware), four (4) omni directional indoor antennas, a surge arrestor, and the rack mount CDS unit. To complete the material list, OCC offers riser or plenum bulk coaxial cable and connectors or custom fabricated coaxial cable assemblies made to length. The figure above demonstrates an application of CDS to a mixed manufacturing/office facility. After it was determined adequate signal strength was available outside the facility, the donor antenna mounted accordingly and the rack mount CDS unit was located centrally inside the facility, as shown above. The following considerations were key in the system design: 1. Provider signal strength was measured to be -65dBm for the wireless carrier, which is excellent for the CDS architecture. 2. Cable length from the external donor antenna to the CDS unit was very short, <50 feet. 3. Cable lengths to the internal antennas were somewhat long, but acceptable with a short donor antenna cable length. 4. The CDS rack mount unit was located closer to the walled spaces of the structure, keeping the signal strongest for propagation through dividing drywall structures between offices. Application of CDS to this facility gave immediate improvement to cellular performance throughout the building, with excellent service in all areas. Typical improvement in provider signal strength at the handset was ~ +25 db gain, bringing signal strength inside the facility to the same level as that experienced at the rooftop donor antenna location. 4G data rates were measured at 14 MB/s at the time of testing, where no 4G service was available prior to the CDS installation.
