The Range of 2 way radios

I don’t know how you came here as you read it on social media, twitter, facebook, google +, stumble upon or somewhere else. thankyou for visiting and I hope you like reading this as much as I did.

A 2 way radio facilitates communication in two directions at the same time. This is possible only when the users who are communicating are within the specified limits in which the radio can operate effectively. The range of this type of radios is limited. This means that they can be used for reliable and effective communication only within the specified distance. Some of these radios are short range while others are long range radios. The short range radios are the ones that can be effectively used for communication within a short distance. The long range radios are the ones that can cover a larger area and facilitate communication between people who are in far off locations.

The range of a Walkie Talkie depends upon several factors. These factors are the following and include the frequency at which the radio operates at, the path between the receiver and the sender of data and the power of the transmitter.

In addition to these factors, the terrain of the area, whether there is any interference present, the type of antenna being used and the type of signal being transmitted all have to be taken into account.

The frequency affects the range in the sense that some radios can work on a single frequency while others can work on different frequencies. When the same frequency is used for sending and receiving data, the range of the radio is short. When the 2 way radios operate on different frequencies, the distance that can be covered by the radio is more. This is mainly because of the fact that different channels are used for sending and receiving data. The path between the sending and receiving radios also affects the range within which the radio can operate. If the path is shorter and has fewer obstacles, the range will be more. On the other hand if there are more obstacles in the path, the range will be low.

The 2 way radios can either be used as low power or high power radios. When the transmitter power is low, the radios can cover a shorter distance. When the transmitter power is high, the radios can cover a wider range. Most radios operate very effectively in line of sight frequencies. This means that they operate the best in plain areas as opposed to hilly areas where these radios cannot transmit efficiently. Also in plain areas, these radios can cover a wider range. In hilly areas, these radios can operate only in short ranges.

If there is interference present or the radio picks up noise or other signals, then it can cover a very short range. When there is no interference from outside signals or noises, the 2 way radios cover a much larger distance and can communicate the message clearly. The type of antenna also affects the range of these radios. If the antenna used is of good quality and powerful, the radio is able to transmit data over a very long distance. If the antenna being used is of poor quality, then these radios are able to send messages over a short distance only.

Ohio district deploys SchoolSAFE solution invented by Motorola dealer

So i found this article on the internet and i was told that just posting it like a whole piece is not the best thing, I got permission from the original author and read up the way to curate articles, so that is it…….i thought this was fascinating because it highlights some of the highs and lows that I encountered when i was working inside the industry.

Chardon Local Schools personnel in northeast Ohio can use their MOTOTRBO radios to speak directly to first responders on a P25 network, thanks to the recent installation of the SchoolSAFE bridge link that was created by a Motorola Solutions dealer in Colorado.

While Motorola Solutions’ ASTRO 25 P25 networks are designed to meet the stringent requirements of public-safety communications, school districts are more inclined to use more-affordable MOTOTRBO radios for daily use, said Patrick Gray, Motorola Solutions’ director of North America channel operations and development.

However, during an emergency, school personnel wanted to be able to communicate directly with first responders that were being dispatched to the scene, instead of having information passed through multiple people—a common occurrence, according to Michael Hanlon, superintendent of Chardon Local Schools.

“Typically, on site, we had a limited number of lower-grade walkie-talkies that were just talking to each other,” Hanlon said during an interview with IWCE’s Urgent Communications. “That information would somehow get to someone—in the school office, presumably—who would make a 911 call. Then, first responders would be reporting to the school or to the scene, and all of that information would flow through whoever might be on the phone with them at the time … but not someone who had firsthand knowledge of the incident.”

Colorado-based QDS Communication—a 13-employee dealer for Motorola Solutions—developed the SchoolSAFE solution that lets a 911 dispatcher activate a bridge between the MOTOTRBO system at a school and the P25 public-safety network, Gray said. The QDS solution has two major components: (1) a “technology tower” that houses a MOTOTRBO and an ASTRO 25 Walkie Talkie that are linked together to create the potential for a communications bridge, and (2) software housed at the 911 center that enables a dispatcher to activate the bridge, if warranted.

“The software that does the bridging technology actually resides at the 911 dispatch center, so the 911 dispatchers are in complete control of turning the bridge on or off,” Gray said during an interview with IWCE’s Urgent Communications.

Hanlon said school-district personnel have embraced the SchoolSAFE concept, which the district plans to incorporate in emergency-incident drills in the future. In addition, the school district is gaining practical experience with the system in situations that tend to happen in a school environment, with Hanlon providing a hypothetical scenario of a student suffering a broken arm in gym class.

“Now, that [school-district] first responder on the scene can be relating exactly what’s happening with the student [in discussions with public-safety personnel],” Hanlon said. “Is this a compound fracture that we’re dealing with? Is the child unconscious? We can be controlling the flow of information much more accurately than having a secretary in the office say, ‘All I know is that somebody’s hurt in the gym.’”

QDS Communications has deployed the solution in about 200 facilities near its Colorado locations, but officials for Motorola Solutions wanted to learn what it would take to install the system in another part of the country. The 10-school Chardon Local Schools was selected, and SchoolSAFE was deployed at no cost to the district.

“It’s a pilot, not in terms of the technology but in terms of Motorola understanding what needs to be wrapped around this solution to implement it—the training and so on—so that we could help QDS package this up, so that we could provide it to our dealer channel,” Gray said. “That was the entire intent here.”

While the current SchoolSAFE solution provides a communication bridge between P25 and MOTOTRBO networks, Motorola Solutions’ recent acquisition of Twisted Pair could allow an expanded method of interoperability in the future, Gray said.

“Now, with the acquisition of Twisted Pair—and we’ve talked about this with Chardon—you can actually take an Android or an Apple cell phone and put it in this same environment,” he said.

Gray said the SchoolSAFE solution will be featured at the Motorola Solutions Channel Partner Expo that will be conducted in Las Vegas on the eve of the IWCE 2014 exhibit hall opening.

Community radio to take care of consumer complaints in Mewat

two way radio uhfSo to continue my run of content on this website, I have planned to share one of our favourite content pieces this week. I used to be tentative to include it to this website because I actually did not want to offend the initial writer, but I hope he/she is happy that I loved reading their work and wanted to share it with my readers.

One of the country’ most backward districts, Mewat in Haryana will get India’s first community radio based consumer helpline on Wednesday. This helpline will be managed by Mewat based community radio station, Radio Mewat.

According to an official statement, the consumer helpline on community homepage is an innovation to raise awareness among consumers in a community. The listeners can call the radio’s helpline number and leave a message, talk to a radio reporter or even come on live with their complaint.

Consumer affairs ministry officials said that Radio Mewat will document the cases and will pass them on to agencies that can sort out the grievances. The department claimed that over five lakh people will be able to take advantage of the helpline by calling the number 8685904904.

The radio will also commit a 30 minute slot to a consumer rights’ program where consumers will have a live show to discuss problems. Major issues such as sale of expired goods particularly medicines, sale of goods without bills, misleading advertisements etc. will be taken up during this particular segment.

The radio-mode to address consumers’ issues has huge significance since literacy rate in this region is low and there is no mechanism that illiterate consumers can use to address their grievances.

Two way radio Operating Guide

With so much information on the internet about two way radio waterproof’s it’s hard to find the top and most direct information. here’s a piece from a good website that i believe as true, don’t quote me on it but please read and enjoy

Are you wondering how to operate a walkie talkie? It’s actually quite simple as they are simple versatile devices that can be used almost anywhere. As you are just learning how to use walkie talkies, we recommend you start with the simplest set possible and go from there. We’ve created a short guide that should prove helpful.

Step 1 — Read the manufacturer’s instructions before you do anything. The instructions will show you where buttons, speakers and microphones are located. Make sure that you charge the handset or put in the required batteries into both models before you start working. Another important point is to check the distance that the walkie-talkie will cover as simple models can only be used over short distances.

Step 2 – Decide how many people will be on a network. If you are using your walkie-talkie over more than five miles, you will require the permission of local authorities and you will have to set up a dispatcher who will coordinate your calls. However, for short distances and for personal use, you can call each other’s walkie-talkies directly.

Step 3 — For long distances, you will have to give each other pennames that will help you recognize each other. This is also useful for short distance use as commercial walkie-talkies usually use the same frequency and you may have people in the same area broadcasting to you by mistake.

Step 4 — Once you have the basics ready, you can actually start using your handset by pressing down on the transmit button. Talk into the microphone of your handset when the button is pressed down. Let go of the button and other people can talk back to you.

Simple tips

1. You can make your conversation private by buying voice scrambled sets. Some handsets have 14 channels with more than 10 sub channels that will keep your conversation on a private frequency.

2. Keep your conversation simple and brief. Always state CLEAR after completing your conversation so that the other person can start talking.

3. Make sure you carry an extra battery if you plan to use your walkie-talkies for an extended period of time. You can also carry batteries that will extend the life of your handset.

4. Handsets are very delicate and dropping them can destroy the circuitry inside the model. If possible, also make sure that you have waterproofing on the Walkie Talkie to prevent permanent damage.

5. Only one handset can transmit at a time and you have to be careful to ensure that the conversation can be carried out in entirety.

6. Wait two seconds after pressing the transmit button. This is because if you start speaking immediately, the first few seconds are lost to the listener.

7. All models have a volume dial, a channel dial and some models have extra dials that offer different functions. Make sure that you do not click on the buttons by mistake as it can completely block up the channel and prevent anyone else from using the system.

The bottom line

Using a walkie-talkie is simple and fun and it is a very common method of staying in connection with friends and family on an outing.
