Motorola Solutions announces new mobile radio, enhancements to its P25 platform

Motorola Solutions are busy re-modelling their business at the moment and are under pressure from many other radio manufacturers, that are stealing away their market share. They are moving towards creating equipment that can use the LTE, essentially competing with the mobile phone market. This will be seen by many as a move away from the essence of two way radios, but it is an inevitable progression. This new radio will use current motorola earpieces, chargers and batteries. We brought you this article from the urgentcomms websites

Motorola Solutions today will unveil a new P25 mobile radio that operates on its ASTRO 25 systems and will highlight key features enabled by the 7.17 release of ASTRO 25 software today at APCO 2016.

One of the key features of the APX 8500 all-band mobile radio is its ability to leverage LTE connectivity from a VML750 modem installed in the public-safety vehicle, if the ASTRO 25 data capability is interrupted by continuous voice transmissions during a busy incident, according to Anatoly Delm, Motorola Solutions’ director of global infrastructure marketing.

“Let’s say that you have a major incident, everybody’s talking all the time and the ASTRO network is being used all the time, it can [offload] some of the data communications, like GPS, to broadbandâ€"public-safety LTE or commercial LTE, depending on what the modem is operating on,” Delm said during an interview with IWCE’s Urgent Communications.

“So, you’ve got this combination of the best of both worlds, where your voice communications are continuing over the ASTRO network, and your data communicationsâ€"if the ASTRO network is too busy, because of a major incidentâ€"can be carried on by an LTE network from the same car.”



Meanwhile, the 7.17 release of ASTRO 25 software will provide system users and operators with features that are designed to improve the reliability and usability of the P25 network, Delm said.

One enhancement is a more efficient way to execute over-the-air software updates, Delm said.

“Ordinarily, what happens is that the software update has to travel to one radio at a time. If you’ve got a large enough fleet, it could take days or possibly weeks [to complete the software update for all radios],” he said. “In this case, the software is being continuously broadcast, kind of like on repeat. In the meantime, all of the radios continue to function as normalâ€"you can talk on them, and none of the functions are disrupted.

“Once a radio has received all of the packets that it needs, it can then give the user the [a notification] that the update is ready and asks whether the user wants to install it. If they say ‘Yes,’ then the radio is updated. This means you can reduce your update time to maybe a few hours, depending on the size of your fleet. But you certainly don’t have to do it one at a time.”

Other new capabilities included in the latest ASTRO 25 software release include personnel accountabilityâ€"often used for roll-call functionality on a fireground or other incident sceneâ€"over trunked systems, Delm said. Previously, this capability existed only in conventional mode.

Make a purchase only after you get a written approval from them. Once you get an approval, you can check the models available at both online and offline store and decide what is best for your home.



The demand for the Wellies increased significantly when World War I started. This is because the army believed that the boots were very durable and they provided ample protection for the soldier's feet even on rough terrain and pilot language translator. After the war, the civilians also began to see the durability of the Wellies and they became more popular not just with the military. Today, it is very common to see at least a pair of Wellies in every household.

If you are lucky, enough to speak two languages from childhood, then you have conquered much of the work that many translators go through. Most have to go to school at least four years to gain an intimate knowledge of their chosen primary language. Some choose to live in a relevant country to gain even more knowledge about the language and culture. For those that have that knowledge from childhood, education is still relevant however. While you may speak a language well, you need to have an intimate knowledge of the written language as well. Many people speak two languages but may only write in one fluently. That many people start their careers with a bit of an advantage.

The sound quality of this gadget is excellent. Also, you get a pair of in-extreme conditions demand extreme responses in the box. Improved S-Pen Stylus is something that you definitely cannot miss out in this phone. It comes with a lot of added features like auto-correct, art package etc. which makes using stylus even easier. There are also other apps like Paper Artist, which enables you to edit photos or images by using stylus.

Music From Your Sunglasses? Zungle's Founders Crowdfund $2M For Shades With Bone-Conduction Speakers

Anything with bone conducting technology, we will jump upon and love the hell out of! When we heard about Sunglasses that had speakers with bone conducting inside, to allow you to make calls and listen to music whilst on the move we thought what a great idea. This crowd-funder is looking to raise $50,000 but $1 million would be a good start. See more on this here.

One of the latest hot crowdfunding campaigns is for dark sunglasses called the Zungle Panther with bone-conduction technology that allows them to be used to listen to music and make phone calls. Jason Yang, Zungle’s 30-year-old CEO and co-founder, came up with the idea because he was annoyed with trying to wear an earpiece and sunglasses to listen to music while wakeboarding.

“We all love extreme sports, and Jason is a huge fan of wakeboarding,” says Sean Bang, 30, Zungle’s chief marketing officer and co-founder. “He’ll have sunglasses on, but eventually the earphone doesn’t work with the sunglasses, and he felt that it was inconvenient and uncomfortable. So we decided to get rid of the inconvenience.”

With Zungle’s sunglasses, wearers can listen to music or make phone calls while skiing, biking or wakeboarding without worrying about an additional earpiece. Bone-conduction technology, in which you hear sound through vibrations to your skull rather than through your ears, isn’t new. But the idea of putting it into relatively inexpensive consumer products, like sunglasses, has been gaining traction recently.

So after fiddling with the product for nearly a year, in June, the two friends, who had worked together at marketing firm Innocean Worldwide in South Korea, along with two other cofounders, Chris Hong and Injun Park, turned to Kickstarter with a stated goal of $50,000 for their high-tech sunglasses. As with many crowdfunding campaigns, that $50,000 number was a lowball one; Yang says “about $1 million” was their actual goal. The Zungle Panther has a similar look to Oakley’s shades, and retails for $150. Backers who chipped in $89 could get them in a choice of colors as a “reward.” “When we started, we didn’t have enough money to create this product,” Bang says. “We chose Kickstarter because we can target everyone around the globe.”



By the time the campaign ended, in mid-July, Zungle had raised more than $1.9 million, putting it among Kickstarter’s top 100 campaigns of all-time.

what to look for when Purchasing earphones

Closed Back Headphones vs. Open-back Headphones

Open-back headphones have pads which rest on the outer ear. They're designed such that the outer shell of the ear cup has perforations usually with horizontal cutouts. The Open back headphones design of the ear cup enhances better natural sound because of less coloration as compared to the Closed back headphones.

Closed back headphones have much larger earpads which encircle the ears. They are designed such that there's a big pad which cups the ears, and it features an insulated outer shell of plastic which covers the ears. The Closed back headphones actually have a very solid outer shell which doesn't have any sort of perforations such that the outer shell effectively cups/encircles the entire ear. The Closed back headphones are excellent at isolating noise. They block most of the ambient noise, but they've a smaller sound stage, which gives the user the perception that the audio/sound is originating from within their head. Closed back headphones also tend to produce much stronger low frequencies as compared to Open back headphones.

Low Impedance vs High Impedance

Headphones normally come in various different impedance levels, such as 8 ohms, 16 ohms and 32 ohms. The power that's supplied by an audio source may be at varying levels because of a variety of factors including being limited because of being battery powered. Generally, as the impedance of the headphones increases, much more voltage will be required in order to drive it, and the audio loudness of headphones for a particular voltage decreases.

The determination of impedance is usually disregarded by many headphone buyers, however, the truth is it's one of the most important factors to consider when choosing the best headphones for your particular needs. Impedance is basically just how much power the headphones can put out so that it can overcome resistance to move the headphones' diaphragm.

Low impedance headphones (that is, less than 25 ohm), usually require little power in order to deliver high audio levels. Low Impedance headphones play well with devices which have weak amplification. These can include; mobile phones, portable music players and various other portable devices. This type of headphones can be used at home and also while jogging with your mobile phone; this is one of the reasons why most of the on-, in-, and over the ear headphones, are low impedance. Low impedance headphones are normally designed to get plugged directly in to a single (one) source, and generates sound more efficiently from a lower level input signal. This headphones tend to be much louder and much more efficient, however, they will also require a much more capable amplifier.

High impedance headphones (25 ohms and above), generally require more power in order to deliver high audio levels. As a result, they're protected from damages caused by overloading. High impedance headphones are typically designed for studio like applications where there might be multiple phones/devices wired in parallel and receiving input signals from a single source. High impedance headphones are more tolerant of the amplifier limitations, however, they will produce less volume for a particular output level. They are also a little more durable (that is, electronically), however, they require much higher signal levels in order to produce the same level of output level of the low impedance headphones. This type of headphones can be used with a wider range of audio equipment.

Passive Headphones vs. Active Headphones

Passive (noise cancelling) headphones are made of materials which help in blocking out sound waves from the surrounding environment. The same way ear muffs soften the outside noise, so does this type of headphones employ passive noise canceling. This type of headphones are typically used for both professional mixing and monitoring, like in broadcast and recording studios, and such other applications. Passive headphones are basically designed to playback music/audio true to the actual original recording, with minimal, compression, EQ, and such other sound enhancements.

On the other hand, Active headphones use batteries in order to power the built in Digital Signal Processing (also abbreviated as DSP) technology which processes play back for a particular reason, for example, to enhance the bass and the high end. Due to the enhancement of playbacks with sharper high ends and more bass, active headphones are more popular for general listening and listening to music for pleasure. Active noise cancelling headphones are also made of materials which help in blocking out outside noise, however, they take things a step further by making their very own sound waves; the sound waves created mimic the outside noises, but are a mirror image of each other, thus cancels each other out.



Wired Headphones Vs Wireless Headphones

When choosing a pair of headphones, deciding between wireless vs. wired is among one of the most overlooked factors. Wireless headphones might be a more popular choice, however, the wired headphones also have their own set of benefits. Well, that being said, as a general rule of thumb, between wireless headphones and wired headphones, assuming a similar price between the models; the wired headphones usually offer a much better quality. Also, the audio quality may get compromised over Bluetooth.

You can opt for the wireless headphones if you are not much of an audiophile, and you tend to travel a lot. If you really don't like getting the cables of your headphones getting tangled, or caught while listening to music/audio, then the choice should be rather simple; go for wireless headphones.

You can opt for the wired headphones if you are an audiophile, and you do not necessarily bother with the wireless options unless absolutely essential like using them when traveling, or keeping the headphones as a backup. As aforementioned, the wired headphones are way ahead in terms of output quality as compared to the wireless headphones. You will never have to worry about running out of batteries, unless you happen to opt for wired headphones which cancel noise. In addition, you will never suffer from interference from the other commonly used wireless electronic devices. However, you will need to take good care of the wired headphone cables, or they will eventually break.

What's the Best 2 way Radio For Very Long Range

When choosing the best 2 way radio, it is important to note that doesn't matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that's up to 30 miles. Truth is, the consumer FRS/GMRS radios don't even provide anything close to the advertised maximum range; the range that a 2 way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.

2 way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 - 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can't travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your 2 way radio; that is without the use of any additional equipment to boost the signals.

VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they're most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.

Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth's surface. VHF 2 way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF 2 way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.

Though VHF can travel much farther, it doesn’t mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you're in or around buildings.

UHF doesn't travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its' used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.

The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF two way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your 2 way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you're trying to communicate with someone on the other side of the building and in between there's a metal wall which has a 3 foot opening. Basically, radio waves can't pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it's wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its' destination.

When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that's dictated by the height of the antenna.

Intel Made A VR Headset And It's Totally Cord-Free

Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to the Oculus Rift,HTC Vive and the forthcoming PlayStation VR headsets. But what separates the Alloy from the pack is that it’s completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.

It does this using two of Intel’s RealSense cameras to continuously map your environment. It can even map your hands.



Intel calls the idea “Merged Reality”, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â€" the processor, sensors and controllers â€" into one cord-free headset.

During Intel’s demo, however, the RealSense camera didn’t seem quite as fluid as you’d hope, especially if it’s your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset won’t be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the software which powers Hololens, according to Microsoft’s Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.

5 Examples of Earpiece to Hear Far Away

1. Using a Mobile Phone And Bluetooth headsets or Earpiece

To do this, you simply need to go into your mobile phone's settings and then change answering mode to Auto; this enables your phone to answer automatically when you ring it. Most mobile phones only work in the Auto answer mode, after you have plugged in the headset.

After turning on the Bluetooth headset, make sure it's properly paired with your cell phone, and confirm the battery has adequate charge. Hide your Bluetooth headset somewhere you know it'll pick up the sounds clearly, however, make sure that it's well hidden.



Leave the room, however, do not go very far. The Bluetooth connection will work through the walls, but if you happen to go far away, it'll not work very well (the range can be up to about 30 feet or 3 rooms away). Now test your cell phone by calling it to see how far you can actually go and still get to hear the bugged room through the Bluetooth headset.

You can wait for the conversations to get to the interesting part, and then turn on voice recorder on the cell phone; it should be able to record via the microphone of your Bluetooth headset.

2. Using a Two Way Radio and Earpiece

Two way radios allow users to communicate when they're far away such that they can not hear each other. These devices use radio frequencies instead of cell phone towers which means they will work in areas where there's no cell phone coverage or reception.

The two way radios offer instantaneous communication; users simply need to press the Push-To-Talk (also known as PTT) key, and they can instantly talk and convey their particular message to the other party. This is due to the quick call setup time that's entrenched in this technology. The ability to offer quick communications is one of the reasons why most organizations prefer the two way radios for their tactical and operational communications.

Another great feature of the two way radios, is the ability to facilitate one to many (also known as, group calls) communications effectively. This basically means that a single user can conveniently communicate with 2, 10, 20, and more, of other two way radio users at the same time. In short, there is no need for you to repeat time and time again when you want to communicate with many people and using a two way radio earpiece, this communication is much more secure

3. Ear Spy Application

Ear Spy App is a great eavesdropping tool. Depending on just how good your cell phone is, this app can become a very high powered listening tool. Ear Spy application can route the audio from your cell phone's mic right to to your headset letting you eavesdrop on the people around you whilst remaining inconspicuous. When using a Bluetooth, you can use this app to spy from a room nearby; you simply need to leave your cell phone near the target, and then use your Bluetooth headset to eavesdrop. If you want to fine tune the incoming signals, you can use the graphics audio equalizer. Whether you wish to eavesdrop on particular conversations or you just want to play some spy games, Ear Spy application will be of great help in your endeavor. You should know that this app requires you to use headphones, otherwise you will get poor audio feedback.

4. Spy Glasses

This spy device comprises of an in built Bluetooth transmitter which looks like ordinary glasses, a microphone and a wireless earpiece. Connections between the glasses, the earpiece and your cell phone are wireless, thus totally unnoticeable to other people; the device's ultra compact design basically ensures nobody will know it is a spy tool. Spy glasses are compatible with almost any mobile phone which has the Bluetooth option. Actually, the Spy glasses are universally compatible with all the standard Bluetooth enabled equipment including computers. Some of the features of this device include; excellent transmission and reception of audio signals, built in microphone, and a large capacity Lithium battery.

5. Micro Air Vehicles (MAVs)

Modern technological advances are ever increasing human's potential for developing tiny things. As for the United States Air Force, this translates to revolutionary designs in the air vehicles to provide the war fighters with new tools which can enhance both the situational awareness, and also the capacity of engaging quickly, accurately, and with minimal collateral damage. This is where Micro Air Vehicles (also known as MAVs) come in. The term MAV or micro air vehicle, refers to the a new type of advanced remotely controlled aircraft (abbreviated as, UAV) that's significantly much smaller than other similar aircraft. Typically, MAVs can easily blend in with the surrounding environment, stay in air for a long period of time, and can go places which can't be reached safely by humans, or most of the other types surveillance equipment.

The target dimensions for MAVs is approximately 6 inches (15 centimeters), and the development of actual insect sized aircrafts is expected in near future. As a matter of fact, various efforts in the research on micro air vehicles have involved attempting to mimic flying insects so as to achieve the flight capabilities which aren't attainable through the use of other means of aerial propulsion. In the year 2007, a bug like Micro air vehicle model with a wingspan of 3 cm was revealed at a robotic's conference; in the year 2008, the United States Air Force released a video showing Micro air vehicles which were the size of a bumblebee; and in the year 2012, some engineers from Johns Hopkins University started studying flight of butterflies to discover how airborne robots can mimic their maneuvers.

The potential military use is 1 of the key driving factors, although the micro air vehicle can also be used commercially, as well as in scientific and mapping applications. The main military use envisioned for the micro air vehicle is gathering of intelligence via the use of microphones, cameras, or other types of sensor.

Conclusion

Some of the above points are illegal, and you should not do any of them. Also, do not use any of the above methods to record any intimate relations; the legal consequences of doing so are very severe. Finally, keep in mind that it's illegal in the US to make recordings of people without their consent/permission; and depending on what you'll do with the recordings, you might find yourself in big trouble.
