BelFone RFID portable radio BF-TD500/501 integrated with RFID function

Portable radios integrated with RFID function As two way radio been more and more frequently used, the trackable and monitorable of it are more and more important. RFID can perfectly solve this and the wireless two way radio communication most efficiency and controllable. What is FRID Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object.  A RFID system is made up of two parts: a tag or label and a reader. How does a RFID system work? RFID tags or labels are embedded with a transmitter and a receiver. The RFID component on the tags have two parts: a microchip that stores and processes information, and an antenna to receive and transmit a signal. The tag contains the specific serial number for one specific object.  To read the information encoded on a tag, a two-way radio transmitter-receiver emits a signal to the tag using an antenna. The tag responds with the information written in its memory bank. The radio will then transmit the read results to an RFID computer program. There are two types of RFID tags: passive and battery powered.  A passive RFID tag will use the radio wave energy to relay its stored information back to the RFID computer program.  A battery powered RFID tag is embedded with a small battery that powers the relay of information.  RFID used in two way radio communication By deployed RFID readers on two way radios, the control center is automatically tracking workers. It knows which workers on duty on what GPS location and time, and can send that information back to computer program over the MOTOTRBO radio. GPS tracking devices for handheld two-way radios are a relatively inexpensive way to track the course of users in near real time. The system’s GPS capabilities can also be used to enhance workers’ routing with team management and security applications. BelFone RFID portable radio BF-TD500/501 BF-TD500/501 upgrade to new version integrated both the GPS and RFID function.

Content about two way radio definition,history,development,users

Two way radio definition A two-way radio is a radio that can transmit and receive in turn (a transceiver), unlike a broadcast receiver can only receive, also unlike a telephone can transmit and receive at the same time. Two way radios transmit and receive signal from the other similar radios which on the same frequency or channel. Two way radio system can both operate in half-duplex mode (like walkie talkie) and Full-duplex (like telephone). Two way radios often operate in half-duplex mode. When it comes to two different frequencies or frequency-sharing which simultaneously carry two directions of conversation full-duplex will be achieved.   Two way radio history As early as 1907, two-way telegraphy traffic across the Atlantic Ocean was commercially available. By 1912 commercial and military ships carried both transmitters and receivers to communicate with ship which is out of site. In Australia in 1923 Senior Constable Frederick William Downie developed the first truly mobile two-way radio. In 1933, the New Jersey police department successfully operated a two-way system between a central fixed station and radio transceivers installed in police cars. During World War II air and ground troops extensively use walkie-talkie hand-held radio transceivers.   Two way radio VS walkie talkie Two way radios and walkie talkie are not the same thing, although in some cases, they can be. There are types of radios that are not portable handhelds, such as a mobile radio mounted in a vehicle or wall mounted base station. A walkie talkie is a portable two way radio that can be held in the hand also known as a handy talkie, handheld transceiver. It allows you to talk on the radio while walking around. More recently walkie talkie became associated with FRS radios and also refers to extremely low power radios sold as toys. Given that, it's no wonder suppliers avoid products labeled as walkie talkies when search for a "real" two way radio.   Two way radio development Trunked radio systems which dynamically allocate radio channels for more efficient use of limited radio spectrum such systems always work with a base station that acts as a repeater and controller. Some cellular telephone networks offers to allow walkie-talkie-like operation over the cellular network.   Who use two way radio Two-way radio has been used for many years by various organizations and industries. Two-way radios are efficient and economic communication tools for any agencies or businesses with multiple staff or workers who work in group and mobile. Examples of organizations and industries that rely on two-way radio are:   ·Public Safety organization: Police, Fire Brigade, Emergency Medical Services / Ambulance, Disaster Recovery agency ·Security: Military, Intelligence agencies ·Transportation: Railway, Airport, Seaport, Light Rail, Subway ·Oil & Gas companies ·Utility companies: Electricity, Gas, Water, Telephone, Cable TV ·Transport Service companies: Taxi, Limos, Trucking ·Construction companies: Commercial, Residential, Road and Bridge ·Hospitality industries: Hotel, Resort, Restaurant, Tourism ·Government agencies: Ministries, Local government, Municipal, Embassies, Public Works ·Services industry: Delivery companies, Towing companies ·Manufacturing ·Contractors: Electrical, Excavating, Plumbing, Roofing Related Readings: encrypted two way radios   systerm two way radio

Why encryption matters and how radio encrypted

Exposes of sensitive information such as police acquired clues, next planning actions, base locations, reporter names and address and etc, would create hazards and trouble. And more, for some expose of confidential information which can be used for criminal purposes, it could make great lost and damage. Because of the potential safety threats, we must encrypted our day-to-day communication and start secure our radio systems. Public safety users consider encryption important. securely communication greatly affect their public and safety serving. We need to provide them best designed tools so that they can take their task most efficiently and safetly. Nowadays, two way radio are secured and encrypted with multiple methods to protect sensitive information. Bleow briefly introduce some two way radio encryptions methods and how it works. How Does Radio Encryption Work? Encryption is encoding information so that signals can’t be understand by externals, and only authorized personnel can access it. Two way radio encryption use coding algorithm to modifies voice signal. Algorithm is controlled by an encryption key which is used to code and decoded voice signal for both radios. Therefore, all radio communication must have matching encryption keys to receive transmissions. 1 Simple Inversion Simply inverts the frequencies and volume of the voice signal. It contained 32 different encryption keys. Radio set this encryption function through programming software. transmissions be able heard only in condition same frequency, same privacy code, same encryption key, within range. It be used in many entry level and mid-tier radios 2Hopping Inversion hopping encryption are more security than simple inversion. Using this method the frequencies and frequency rates change irregularly. It be used in commercial market in the 900MHz range. 3Rolling Code Inversion Voice signal is inverted at a constantly changing rate. Rolling code encryption have 1020 encryption keys to choose from. The keys are set in the radio by programming software. With much more codes (1020 for rolling) than simple inversion plus the "rolling" inversion make it more difficult to break. It be used by some mid-tier radios, most advanced radios 4DES and AES Encryption 4DES and AES Are "gold standard" when it comes to encryption. DES was developed in the 1970's but has been replaced by it's newer cousin AES in many applications. However just like real gold, it is higher cost and complexity. Compatibility of Encryption Between Different Brands As AES and DES are standardized encryption methods. So AES and DES would be compatible between different two-way radio brands. As each manufacturer can set their own codes and scrambling techniques for simple and rolling code inversion, simple inversion or rolling code inversion encryption are generally not compatible across brands.

Choose suitable two way radio to your precise working environment

Maybe some high quality and versatile two way radio can suitable for every business or industry uses. But it could not the best choice for some scenes if take into account the cost. The radios that firefighters carry into fire scene will be greatly different from the radios waitress use to serve you at a restaurant. So, choose matching radios to your precise working environment is important and necessary. You need to choose two way radio you buy depending on the environment it will be used in. Otherwise, either the radio you purchase would not affordable for the using environment, or some features would be neglected and result in disaster or life lost. Consumer-grade walkie-talkies are like toys, with low power, limited frequencies, crowded channels and easily-breakable design. Dedicated professional radios are built to be used every day in rugged environments to suit the needs of specific sectors. Professional radios also come in a wide range of designs and feature sets that depend primarily on the environment where they will be used. Here’s a look at several common differentiators and options: Heavy or Light Usage Whether if choose durable radio depend on using intensity. A construction worker needs a more durable radio than a hotel manager. Whether if choose long battery life radio depend on daily using period or using frequency. A shipping dispatcher needs a radio with a long battery life, whereas a teacher monitoring recess may only use her radio occasionally. Indoors/Outdoors Radios don’t need protection against moisture or extremes of heat or cold in dry and temperature-controlled indoor environment. But, radios need specific safety features or protection against moisture and particulates in some hazards environment. Radios require greater sealing to against water and dust in outdoor settings. People working in marine settings, mining and construction are examples where radios need added environmental protection. Highly Hazardous Operations Safety features are special important in highly hazardous operation. Below list some most common safety features. · Intrinsically Safe (IS). Designed for hazardous locations where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust or ignitable fibers or flyings. IS radios are sealed to prevent sparks that could set off an explosion. · Man-Down Alert. This feature sends an alert when a radio remains tilted beyond a certain setting for a specified length of time. It’s a beneficial feature for workers in remote locations. · Emergency Alerts. Some radios have a “panic button” the user can push to summon help quickly. · Impact Resistance. Construction sites and factories often require a radio that can withstand getting dropped and kicked around repeatedly. · Remote Monitor. discreet communication, even talking without PTT can be monitored by a supervisor radio without any indicator or being known · GPS positioning Related readings: two way radio   digital mobile radio

Xm Satellite Radio Replacing Free Radio?

Remember the days when we thought paying for our TV service was ridiculous? “Cable TV!”, our mothers would exclaim, “Who has money to pay for their TV shows? It’s been free all these years; I don’t know why I would start paying for it now.” But that was then and this is now. Today we pay for cable or satellite and consider it a necessity in our lives, not a luxury. Sure, we could stick with “free” TV, but the reception would be bad, we’d only have 4-6 channels to choose from and there would be no CNN, no Food Network, and no ESPN. What would we do with ourselves? So it seems a little reminder of those days when we hear people scoffing at the notion of paying for radio. “I’ve gotten it free all these years,” you hear people exclaim. “Why would I pay for radio?” Although satellite radio services have been around for a few years, its notoriety was spun into high gear when Howard Stern publicly made the jump from “free” radio to a satellite service in early 2006. Now, everyone’s curious and many people are considering paying a bill every month for the privilege of listening to the radio. If politics aren’t your bag, how about entertainment or humor? On XM Radio channel 162, you’ll find the E! channel. Yes, this is the same E! we pay for on cable and the format is generally the same. There’s the E! True Hollywood Story, E! news and celebrity profiles. Now you can get all your E! gossip and news while drinking Starbucks on your way to work. My, how the world has changed. Amid all this talk, there is music on XM Radio. Lots and lots of music. There are alternative music channels, top 40 channels, channels for 60s music, 70s music, 80s music and 90s music. Interested in music from Sweden and Ireland? Check out channel 29, or U-Pop, dedicated to hits from around the world. Needs some romance in your life? Turn your dial to The Heart, where you can enjoy Whitney Houston, Michael Bolton, Celine Dion and the like. Today we can see different kinds of radios in our life, for example DMR two way radio and so on. Related readings: Analog two way radio analog communication repeater
