Shippers, receivers, and distributors of perishables need a way to track shipments — not loads, shipments — accurately, says Bob Twitchell, chief technology officer for Intransit Networks in Seattle, Washington. Current mobile tracking systems can follow tractors or trailers, but tracking an individual pallet of broccoli or fresh meat still relies on batch-processed paper processes. Those who deal in perishables need a way to track inventory and workflow in real-time, he says.
A number of new technologies have the potential for a combination that will allow location, tracking, and communication with refrigerated goods, Twitchell says. These technologies include cellular/PCS networks, global positioning satellites, “Bluetooth” low power radio, wireless identification tags, and the Internet.
Low power radio frequency communication is developing rapidly, and both the Wireless Ethernet and Bluetooth have the potential for global coverage. In general, these radio systems are for point-to-point communication; so far, limitations in the control of such networks have prevented large-scale use.
Most tracking systems are unwieldy and expensive, Twitchell says. Many tracking systems use portal technology with radio frequency tags and fixed readers that capture information as goods pass the reader. Once on a trailer yard or in a warehouse, portal technology loses track of the tag, he says. This prevents the system from checking inventory on command.
Intransit Networks has a new approach to tracking that it calls a class-switched network with six modular components. This network gives users an affordable, accurate, and flexible method for tracking and inventorying shipments. It controls low power radio tightly in a network built around the way users plan to interrogate and inventory assets, Twitchell says. A class-switched network has low power consumption, high efficiency, low noise interference, and high flexibility.
The six components in such a network are a radio frequency tag, a low power radio or repeater, a mobile locating gateway or scout, a network interface module or gateway, a handheld interrogator, and a web server. Radio frequency tags are low cost radios with a small battery (sometimes no battery at all) for communication with a reader/repeater. Cost of an RF tag can range from 50 cents to $2. Typical range for a semi-passive tag is 20 feet from the reader.
Tags are located by low power radios that read or write information on the tag and pass that information along to other repeaters for subsequent transmission to increase the range of the total system. Users can communicate with the repeaters with handheld computers or across the Internet. Repeaters in the Intransit Networks system are based on Bluetooth standards for functionality, cost competitiveness, availability, and global coverage, Twitchell says.
The mobile locator or scout is a combination mobile phone, low power radio, and global positioning system receiver. It can track RF tags anywhere a mobile phone network is available. The locator also can communicate with RF tags placed in individual shipments.
The network interface or gateway is the base for the class-switched network. From a fixed position, it translates the Bluetooth protocol to Ethernet, PSTN modem, or other communication network for transmission of data to the Internet. The handheld interrogator in the Intransit Networks system is a combination Bluetooth module and handheld computer that provides access to information on the wireless tags from the repeater network and communicates with the web server.
The web server with its application database contains the operating system for controlling and accessing information on the network. The server, working with the other components in the network, can provide real-time shipment tracking, Twitchell says.
A class-switched network allows users to track goods from processing through shipping and warehousing all the way to the point of retail sale, Twitchell says. The system is streamlined so that information is collected only when directed. Based on existing radio standards, such a network can be built with off-the-shelf components and customized with individual software.
The projected cost of a class-switched network should be one-half to one-third of the current $600 to $1,500 per truck tracking system now used. Wireless warehouse inventory management systems cost between $350,000 and $500,000, roughly three to five times more than a class-switched network, Twitchell says.
Mobile tracking is growing rapidly. About 650,000 trucks and more than one million automobiles already have tracking systems. Some researchers project that 10% of all automobiles will have tracking by 2004.
Intransit Networks expects to have class-switched networks capable of tracking vehicles and containers available by January 2002, Twitchell says.
Consolidated Metco Inc has unveiled its newly redesigned web site, located at www.conmet.com. Detailed images and descriptions are included on the TaperLoc slider, part of ConMet's Simplex fifthwheels. Users also can access magnified views of slide rail features, such as the tapered lockpin that moves deeper into the lock pocket as the slide rails wear.
Other highlights include procedures for coupling and uncoupling an air-ride or non-air-ride suspension. The site's comparison charts assist in understanding wheel-end compatibility with brake components and installation requirements.
Aluminum hubs and PreSet wheel ends can be specified using an online interactive selection guide, and cast brake drums can be selected using the Drum Selection Guide. Downloadable brochures, manuals, and bulletins are available for all ConMet products.
SDA FreightDATA Corp introduces its FreightDATA transportation software with web tracking capabilities. The software is designed for small- to medium-size companies to handle management of a freight carrier business, from accounts payable and automatic rating, to credit and collections. New web-tracking capabilities are estimated to reduce administrative and support costs associated with locating shipments en route.
This software provides electronic dispatch, rating, billing, and accounts receivable for various trucking requirements including less-than-truckload, truckload, drayage, ocean and air freight forwarding, and air cartage. All freight bills are accessible in the system by various search criteria, with daily activity and revenue reports posted automatically to the general ledger, accounts receivable, and various statistical files.
Web-tracking capability allows the user to check the status of a shipment, access activity reports for the past month, and print images of actual bills of lading and Proofs of Delivery online, pinpoint time and date of delivery, and obtain the name of who signed for a shipment. For more details, contact SDA FreightDATA, 20311 SW Birch St, Suite 200, Newport Beach CA 92660.
