The Different Types of Two Way Radio

What would you do if i said I have found a radio earpiece piece that is not only fascinating but informative also? I knew you would not believe me, so here it is the enlightening, excellent and fascinating article

A two way radio is also known as a transceiver. These radios are used for both for sending and receiving data or signals. These radios can either work on analog technology or a digital technology. When analog technology is used in these radios, the transmission can be done clearly even for very weak signals. However, in analog technology, only one thing can be done at any given time i.e.
data can either be vent or received. When digital technology is used, data can be sent and received simultaneously and also more data can be sent.

Two way radios come in two styles. These are duplex and simplex styles. In the simplex radio, only one channel can be used at any instance of time. This means that only one person can send data at a time. The most popular type of a simplex radio is the walkie talkie.
The duplex radio is the one in which different channels are used for transmission of data. This means that any given time, the use can both send and receive data but using two different channels.
The two way radios are generally of two types. These are Family Radio service, FRS, and General Mobile Radio service, GMRS. The family radio service is mainly used as a personal radio that facilitates two way communications. The range within which these radios can operate is two miles.

These two way radios operate on very low frequencies that allow people in close proximity to communicate with each other. These radios are not suitable for a long range communication. These radios also have special bands on which they operate and are not so powerful that they can be used on a daily basis.
In addition, these radios operate the best in a line of sight. These radios cannot operate very effectively when there is an obstruction or the terrain is not plain. These types of radios cannot work well in mountains. The family radio service radios are very affordable as they mainly cater to the needs of the families.

They also have features best suited for personal needs.
The general mobile radio service radios are fast replacing the family radio service. One of the main reasons for this is the fact that the general mobile radio service radios can be effectively used for communication over long ranges. These can operate within a range of 20 miles.
These radios also operate the best when there are no obstructions and the terrain is plain. These two way radios cannot be efficiently used in hilly areas. These radios are very powerful and are best suited for use in military organizations. These types of radios are expensive and a user also requires a license to operate these radios.

These radios come with a lot of features. Most of these radios these days have a feature that tells about the weather. These also have features that can be used for navigation purposes. These 2 way radios are generally hand held and easy and convenient to use and operate.

Making Her Into Reality

Making “Her” Into Reality
What would you know, this website About keyword is definitely interesting, i hope you enjoy it

Spike Jonze’s latest movie, “Her,” creates a future where technology is less visible, yet more ubiquitous than today. The main character uses an earpiece and handheld device to communicate with an operating system that follows a user across any platform, rarely utilizing the traditional desktop screens except when at work. And the main way of interacting with the operating system is through natural, conversational speech.

Even though it is science fiction, “Her” seems to be the end state for many current acquisitions and research from real-life tech companies. These companies are pursuing enhanced artificial intelligence and speech recognition. And the companies who don’t jump on this future will be left in the digital dust.

Established artificial intelligence
The most well-known characters in AI today are IBM’s Watson and Apple’s Siri.

Watson takes human’s natural language and filters through data to find the most probable answers. It can take “unstructured data,” that is, data computers typically cannot read because it isn’t structured in tables, rows, or columns, and turn it into knowledge accessible not through complex queries but simple, vocal questions. It’s now being used to help doctors find better cancer treatments and financial planners find better investments. IBM hopes Watson will bring in $1 billion in revenue by 2018.

Siri first debuted in Apple’s iPhone 4S, allowing for simple functions like searching the web and initiating a call or writing a text message. The latest iOS version added more functionality for Siri, like sourcing information from Wikipedia and Twitter.

Apple’s latest acquisitions point to further enhancements for Siri. In 2013, the company picked up intelligent calendar application Cue, which helps layout a user’s day similar to Google Now. It also bought Topsy, which allowed customers to analyze and search social posts. And, a recently published patent points to expanding Siri from phones to docks.

Up and coming AI
Now, Google spent a rumored $400 million on an artificial intelligence company called DeepMind. DeepMind’s website describes its software as useful in “simulations, e-commerce, and games,” and the company has an impressive talent list with a former child chess prodigy and a Skype co-creator. This piles on to Google’s other recent acquisitions of robot maker Boston Dynamics and smart home hardware maker Nest. If Google can succeed in integrating these seemingly disparate companies, it seems like having a conversation with your thermostat isn’t too far off.

Losers of an AI future
While these companies are priming themselves to own any science fiction-like future, there are companies doomed to languish if they don’t change their path.

This includes the lowly hardware maker. The future presented in “Her” doesn’t contain several devices in multiple form factors as we have now, but one handheld device and one wearable earpiece that connects to a cloud-based operating system. IBM, a case study in staying relevant, keeps shedding its hardware operations with its latest $2.3 billion sale of its server business to Lenovo. As the main players build their artificially intelligent ecosystems, the hardware becomes less important as it’s commoditized, and the main differentiation becomes software. Companies might also want more control over their hardware and the user experience, and produce their own. For example, Apple recently purchased a cutting-edge chip maker, Primesense. Microsoft stepped into producing its own hardware with its Surface tablets.

Just a movie?
On the other hand, “Her,” like most future predictions, could be far off base. While it seems artificial intelligence will play a large role in future computing, we may combine such technology with even more screens. The point where computers become more intelligent than humans, called the singularity, may not come as quickly as predicted, and these future bets may be too far off to have any impact on company values today.
