						   Fixed Broadband Networks Fixed broadband radio networks are a
                           cost-effective alternative to placing new fiber in
                           developed areas. The cost of placing new cables in a
                           seaport environment can be quite high due to channel
                           crossings, pavement
                           cutting, trenching and building entry issues, not to
                           mention being disruptive to port operations. Fixed
                           point-to-point microwave radio networks have the
                           advantage of being less expensive and much quicker to
                           install in these instances. The services provided for
                           fixed radio networks in seaport applications include:

						   Radio Links Extending Fiber Networks The use of fixed radio links to augment existing
                           fiber-based networks is becoming more common as
                           broadband applications get further from the
                           administrative offices. The majority of fiber systems
                           were initially deployed to serve office buildings,
                           government facilities and educational institutions.
                           In a seaport environment, fiber does not reach all
                           of the locations where broadband communications is
                           normally needed. Fixed radio links can be an economic
                           alternative to extending fiber systems. The services

						   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. Radio links used for video surveillance are a
                           special application of fixed broad-band radio
                           networks described above. Depending on the
                           application, either licensed or unlicensed radio
                           links can be used, with the licensed links providing
                           protection from interference. The services offered

						   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 port. 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. We expect to deploy this system later
                           this year. The services offered in LPS include:

						   RFID Systems Radio Frequency Identification (RFID) systems are 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 non-metallic container. RFID systems are
                           currently used in supply chain logistic applications to track
                           items as they pass through the various parts of the
                           supply chain. A limitation of these systems is that
                           portals must be installed to read the tagged items as they pass
                        through them, 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 a seaport
                           environment, RFID technologies can be used to track
                           items as they move throughout the port, 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.

						RF Surveys & Spectral Analysis Radio Frequency surveys and spectral analysis is a
                           powerful tool associated with wireless system design.
                        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 always advisable that an RF site survey be performed
                           prior to purchasing and installing equipment. This
                        provides assurances in advance that there are not any interference
                        sources that could be "show-stoppers." For smaller installations,
                        RF site surveys 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
