Radio Links for Video Surveillance

Video surveillance using streaming video over Ethernet networks has become very popular in recent years and is seeing wide-spread implementation. The biggest impediment to deploying these networks is connecting the camera locations to the rest of the network, and depending on the system architecture, fixed point-to-point or point-to-multipoint can be used.

Indoor & Outdoor Local Positioning Systems

Local Positioning Systems (LPS) are seeing more and more application as a means to track personnel, high-value assets and supplies throughout the airport. The Global Positioning System (GPS) is well known for its ability to locate objects using using a constellation of satellites and low-cost portable receivers. The biggest problems with GPS are twofold. First, GPS only works reliability when there is a clear view of the sky, and second, that while the object knows where it is, some type of communications link is needed to convey this information to a central control location. PCN Professionals, in association with one of its partner corporations, has studied this area and has developed a concept that can be deployed using commercially available equipment and will provide location data both indoors and outdoors. The services offered in LPS include:

• Requirements definition

RFID Systems

Radio Frequency Identification (RFID) systems are currently a hot topic these days. With these systems, objects are identified using radio waves to interrogate a tag on the object, even though it may be inside a carton or container. RFID systems are currently used in supply chain logistics to track items as they pass through the various parts of the supply chain. A limitation of these systems is that portals must be set up to read the items as they pass through, and these portals must be connected to a data processing system running a logistics management package. If multiple portals are involved, then wide-area networking becomes necessary. In an airport environment, RFID technologies can be used to track items as they move throughout an airport, and record hand-off transactions as they are passed from one user to the next. Wireless technologies provide the means to network multiple portals at a large facility and allow the use of hand-held wireless RFID readers. The services offered associated with RFID systems include:

• Requirements definition for the communications network
  • Define the functional requirements of the communications network
  • Review operational & cost implications
  • Develop technical requirements based on the functional requirements

RF Surveys & Spectral Analyses

Radio Frequency surveys and spectral analysis is a powerful tool associated with wireless system design. On occasion, our clients elect to plan and deploy their own wireless equipment for smaller projects. There are numerous wireless devices deployed these days, all of which share common blocks of the radio spectrum. Because of the proliferation of RF devices, it is recommended that an RF site survey be performed prior to purchasing and installing equipment to be sure there is not any interference that could be a "show-stopper." For smaller installations, this may not be feasible, but for the deployment of large systems using license-free spectrum, it is highly advisable. The services offered for RF site surveys and spectral analysis include:

• Spectral sweeps at all frequencies that have equipment that can meet the requirements
• Identification and documentation of all potential interference sources
  • Type of signal
  • Source
  • Location
  • Intensity
  • Frequency & bandwidth
• Assessment on the impact of the system planned for deployment
• Recommended mitigation measures
  • Customized hopping sequences
  • Channel selection to avoid interference
  • Shielding & other mechanical mitigation techniques
