Home World News Latest Articles Escape Hatch ... Endless Buzz Using Radio Communication in Business Radio Communications are proving to be extremely popular with business who want fail safe communication at a fraction of the costs of more traditional forms of communication. This article looks at how using Radio Comms could be just what your business needs. Radios are used as a means of communication in all types of organizations. These can be used in governmental and non governmental organizations, shopping malls, schools, hospitals, police stations etc. These are considered to be the most cost effective means of communication. The radios are also the most reliable means of communication that is preferred over various other communication media like cell phones, internet etc. Also communication over a radio does not require any medium to carry the radio waves. This enables one to send even high frequency signals. Radio communications use radios of two types, namely, the very high frequency radios and the high frequency radios. The very high frequency radios are the ones that are used for communication over shorter distances as they work the best when communication is done using line of sight propagation. This means that these radios work the best when there are no obstructions in the path of the traveling signal. The high frequency radios are more suitable for communication over longer distances. When using radio communications, there are several things that must be kept in mind. The first is that one needs to get familiar with the communication netiquettes that need to be used over the radio. A person must use very short messages and use very simple language for them. This enables the message to travel faster and also reach the receiver clearly. When using radios for communication purposes, it must be ensured that no private or confidential information is sent. This is because any one can hear this message if one’s radio catches the frequency on which the message is being sent. Also for radio communications, it must be ensured that the radios are always kept in good working conditions. People using radios must always ensure that the radios are checked regularly and maintained properly.

Lab 3: SPOT Radio Communication Background Reading: SunSPOT Developer's Guide, pages 25-37 Before starting this lab, you should look over these pages of the SPOT developer's guide which briefly cover the provided SPOT device libraries. Some of this can be skimmed; the idea is for you to get a feel for the SPOT API that you will be using to develop applications, and hopefully pick up ways to do some of the most common tasks. Do pay close attention to the section on the radio communication library, starting on page 29, though, as that is what this lab is concerned with. Socket Programming Introduction: http://www.javaworld.com/javaworld/jw-12-1996/jw-12-sockets.html . If you haven't encountered Java socket programming before, it would be a good idea to go through this tutorial that introduces the concepts and relevant parts of the Java API. The JavaWorld tutorial, though good, only covers TCP sockets. For a brief coverage of UDP socket programming in Java, check out these slides: http://www.cs.rpi.edu/courses/fall02/netprog/notes/javaudp/javaudp.pdf Prelab Question: What is the difference between the Radiogram and the Radiostream protocols provided by Sun for SPOT applications?

OSHA Biweekly Newsletter RSS Feeds Print This Page Text Size Home Workers Regulations Enforcement ... Offices Radio Communication Can Assist Container Gantry Crane Operators in Marine Terminals Container gantry crane operators load and discharge hundreds of containers in a systematic fashion. The crane operators rely on their line of vision and on signals or directions from employees on the ship and on the ground below to guide them in their lifts. Risk of injuries can be reduced by the use of radio communication by the crane operators and longshore personnel. Hazards of Container Operations Container ships come in and out of ports on a regular basis. At each port, containers must be discharged and loaded. This requires close coordination by terminal and longshore personnel working on the ground, on the ship and in the crane. Employees on the ground and on the ship must pay close attention to their surroundings at all times. Employees have been crushed by containers (either falling or being set down), run over by vehicles, and crushed by moving cranes. Cargo operations are particularly hazardous when things do not go as planned, such as when a twistlock becomes jammed, when a container is placed in the wrong position on the ship, or when a vehicle is accidentally lifted along with the container. The Need for Communication Depending on the particular operation, employees under the crane and/or aboard ship may need to communicate with the crane operator. These employees must be able to communicate rapidly and accurately with the crane operator to help direct the operation and ensure that safety is maintained. During routine operations, employees typically communicate with the crane operator using hand signals recognized at the port. However, during non-routine tasks or in an emergency, employees may need more interactive communication with the crane operator. Non-routine tasks include handling oversized or unusually shaped cargo, hoisting personnel, and handling damaged containers or jammed twist-locks. Emergency situations can occur when one employee sees another employee beneath a load, or when a container is not properly disconnected from a chassis, resulting in accidental lifting of the tractor and chassis with an employee inside.
