It has countless unique and interesting features, but perhaps the most defining is its use of the Z-axis. Basically, it adds a little skeuomorphism back into flat design, creating the impression of a bunch of two-dimensional planes floating over each other at designated elevations.

What is an iBeacon?

iBeacon is the Apple Trademark for an indoor positioning system that Apple Inc. calls “a new class of low-powered, low-cost transmitters that can notify nearby iOS 7 devices of their presence. The technology enables an iOS device or other hardware to send push notifications to iOS devices in close proximity. Android operating systemdevices caBEACON_High_School_1_259777n receive iBeacon advertisements but cannot emit iBeacon advertisements (ie. central role only).

The iBeacon works on Bluetooth Low Energy (BLE), also known as Bluetooth Smart. BLE can also be found on Bluetooth 4.0 devices that support dual mode. One potential application is a location-aware, context-aware, pervasive small wireless sensor beacon that could pinpoint users’ location in a store: iBeacons could send notifications of items nearby that are on sale or items customers may be looking for, and it could enable payments at the point of sale (POS) where customers don’t need to remove their wallets or cards to make payments. It could be a possible Near Field Communication (NFC) competitor.

It uses Bluetooth low energy Proximity sensing to transmit a Universally unique identifier picked up by a compatible app or operating system that can be turned into a physical location or trigger an action on the device such as a Check-in on social media or a push notification.

Various vendors have made hardware iBeacons that come in a variety of form factors. This includes small coin cell and AA powered devices, USB sticks, and software versions using Bluetooth 4.0 capable USB dongles.

As soon our team lead purchased  Droid devices for me and co-workers It was super cool and a speech less moment while having a smart-phone.I gone with it, and felt that I’m in the world of fantasy

Recent work conversations about mobile made me take a look at my pattern of usage with the Droid, and I came to realize that aside from using the Droid  and taking a couple of 8Mpx snaps that essentially, I’ve been using the Droid the exact same way I had used my old flip phone

When it comes to the basic features smart-phones most phones have the same core functionality. This would be the ability to act as a communication device, a multimedia device, and a mini application operating platform. It become a core piece of technology in the modern world, indeed, it is almost impossible or one to go through their day without using, or encountering a person who is using a smart phone.
Droid help me to  improved my creativity and give the world in my hand .
