Dear ColorOS Superfans,
coloros copy.jpg
Hey all my friends, today I have come up with a new topic on connectivity features
that we had/have in our mobiles phones.  It's not just an article but an important  piece of information that we all live with and cannot live without in future. I have tried my best to gather the source to make you people understand how these functions work and why it is needed.


Let's get on to the topic, We cannot simply use mobile phone for only voice calls and if the manufacturer has thought the same, our smartphones wouldn't have had these many features that we have nowadays. We are at a position to use only mobile phones for all our data / Money and communication transfer.


Lets me elaborate it one by one


Infrared


Infrared connectivity is an old wireless technology used to connect two electronic devices. It uses a beam of infrared light to transmit information and so requires a direct line of sight and operates only at close range.
IR was superseded by Bluetooth, which has the advantage of operating at longer distances (around 30 feet) and being omnidirectional.

Bluetooth


Bluetooth is a wireless technology that allows you to transmit and exchange data over short distances.  But unlike other wireless technologies, Bluetooth allows you to connect several devices at once.


Bluetooth technology is used to gather location data from GPS.  This is good for offline data logging wherein the Bluetooth device would automatically keep track of all the location data from the GPS and then logs it. To view the data, you would need to download it and see the completed route on a map.
Now you have an idea of how wireless technologies to aid in fleet tracking systems.

Wi-Fi



Since the advent of smartphones, the previously bright line between phones and computers has gradually blurred. Thanks to faster processing power and larger feature sets, the differences between the two have been reduced. In one significant example, Wi-Fi enabled phones to allow smartphones and computers to access the Internet via the same kind of connection.


Hardware
Having Wi-Fi on a cell phone means it can connect to any wireless network just as a wireless-enabled laptop or desktop can do. Users can use the phone's interface to log into a network and use the data connection for tasks such as email or multimedia streaming.

Availability
Wi-Fi typically comes as an installed feature on modern smartphone platforms like Google's Android, RIM's BlackBerry OS and Apple's iOS. Lower end cell phones lack the processing power to make the most of online content, so Wi-Fi is usually omitted.

Financial Benefits
Using a Wi-Fi connection on a smartphone diverts some of the load from a user's data plan. Through Wi-Fi, the phone only downloads data content through the local network, instead of the carriers. This can save some money because many carriers have data caps on smartphones -- if a user downloads enough content to exceed that limit, extra charges can be incurred.

Performance Benefits
Carriers often tout the high speed of their 3G networks, but performance can vary greatly, depending on your location. Because local networks have consistent and higher transfer speeds, it will often be much easier to download and upload content from a smartphone via Wi-Fi.



Near-Field Communication (NFC)


You may have heard about near-field communication when you talk about Google Wallet and a slew of other mobile payment services out there. Near-field communication is big in the mobile payment industry as it provides you with a way to pay for purchases using a smartphone with an NFC chip embedded on it and a mobile app that stores your financial details. The sell is that instead of counting up your cash or swiping your credit card, you only have to tap your smartphone on a terminal and you will be able to pay for your purchases.


What is near-field communication?  Near-field communication is a set of standards that uses short-range radio signals to transmit information between two devices.  It is a close cousin of RFID or radio-frequency identification.  Aside from mobile wallets, near-field communication has also been used by passengers to pay train and bus fares.  Other uses of near-field communication include:


  • Social uses.  Social uses include tapping your NFC smartphone on a new acquaintance's likewise NFC-enabled smartphone in order to exchange contact details, videos, photos, mp3s, files and even Facebook and Twitter profiles.


  • Smartphone automation.  Near-field communication comes with NFC tags that you could program in order to automate your smartphone.  For instance, you could put an NFC tag in your car so that when you get in, your phone would connect to your vehicle’s connected car system via Bluetooth.  An NFC tag on your desk at work could also automatically switch your phone to silent mode.


  • Access.  You can also use near-field communication for keyless entries.  For example, there are now NFC locks available that allow you to open your door using your smartphone and you would no longer need to rummage through your bag to get the keys.  You can also use near-field communication to store your access credentials on your phone so that you would not need to use a key pass or a card pass to enter sensitive areas in the office.


  • Wireless connections.  You can use near-field communication to make it easier to pair your devices via Bluetooth.  Instead of going through several steps in order to successfully pair two devices, you only tap your phone to an NFC tag that will handle Bluetooth pairing.  Furthermore, you can use NFC tags to let people connect to your Wi-Fi connection so that they would not need to know your password.





NFC could be used on your driver IDs.  Once your driver gets on board his vehicle, he would need to tap his ID to connect to the satellite and Internet, as well as transmit his identification and credentials to your system.  This way, you can track your driver's behaviors even if they use different vehicles.  In fact, you really do not need a driver's ID anymore, you could just use his Android smartphone to do the task.

QR Codes
QR codes are an early entrant into the wireless tech space. QR codes work like traditional barcodes with two very important differences.  For one, it looks like a pixelated box that can contain more information than the standard bar code with its series of vertical lines and, two, you would need to scan it with a reader in order to decode the information. By reader, we mean a smartphone with a camera and a QR code scanning application installed on it.
QR codes right now are most closely associated with sales and marketing.  It is everywhere, with companies putting QR codes on their marketing materials, brochures, business cards, flyers, stores, billboard ads and even clothing.  One scan and it will take you to the relevant content that the company is trying to sell.  For example, a company might put a QR code on its direct mails.  When you scan these QR codes, you might be taken to the company’s Web site or that product’s online page where you could learn more about the product, see photos of it or even watch a video on how to use the product.  But the most important thing is that that page would allow you to buy the product right on your smartphone.  A QR code can contain anything from videos to photos and even URL links.


But QR codes have been around since the 1990s and it was first used as a way to track vehicle parts.  In the same way that you could track your cargoes and, to an extent, your fleet.  You can just scan the QR codes on your cargoes and your vehicles instead of manually logging this information.  This way, the whole process is faster and error-free!


Hope this article is helpful for you all.
