Google Glass

Google Glass is the project developed under Google X research and development lab. It is a wearable computer having some of the specifications like 1 GB RAM, 16 GB Flash, Dual core SoC CPU, 5 MP camera and android OS. It accepts voice command as input to take photos, send message, play music, search on web, etc.

See. Speak. Capture.

Just say the word and Google Glass will take a picture or record a video – you will never have to touch the hardware. The photos and videos will be stored on the 4GB flash memory of the device, and can also be shared over social networking websites or email.

See. Record. Share

Google Glass can show the world what you are seeing – live! If you are attending a family function, your child’s school play or a concert, you can share the feed with your friends and family in real-time and make them a part of the experience.

Directions right in front of you.

The widely used Google Maps are integrated into Glass, so that users will be able to chart the course of their journey or look up locations or establishments via voice commands.

Speak a message. Send.

Google Glass will show you text messages as well as emails you receive and allow you to reply to them via voice commands.

Ask whatever’s on your mind.

If you are in the habit of Googling things a lot, you will find that your task has been made easier by the new Glass. You simply need to ask a question and the device will pull the answer from the internet. For example, you can ask when Taj Mahal was built or to give you a few photographs of the monument and the device will provide appropriate replies on the small screen in front of your eye.

Speak. Translate.

This is a neat feature that may come in handy when you travel abroad. You simply need to ask Google Glass to translate a phrase or sentence from one language to another and it will speak that out.

Google Now.

Google Now, the digital voice assistant from the search giant, has been integrated in this device. It will keep track of your daily habits, such as when you leave for office or the route you take. It will give you alternate routes if there is traffic on the way or give you weather updates periodically, among various other functions.

The technology behind Google Glass is Augmented Reality (AR). This we shall discuss later.

LTE :A Step Ahed

The world is on the edge of wireless connectivity. Everything needs to be connect through internet. Bandwidth shortage is the fundamental issue for any of the mobile network generation. Long Term Evolution is the latest standard in mobile network which is developed under 3rd Generation Partnership Project (3GPP).

LTE is up gradation from the 2G/3G services, as from GSM to UMTS to HSPA or CDMA and CDMA to LTE.

Features

§                                §  Higher data rates:

        Downlink: 100Mbps     Uplink: 50Mbps

§  Efficient spectrum utilization:

        DL: 5 BPS/Hz UL: 2.5 bps/Hz

§  Scalable carrier bandwidth: 1.4MHz to 20 MHz

§  Reduced cost for operator

§  Improved system capacity and coverage area

Architecture

The LTE physical layer is based on OFDM (Orthogonal Frequency Division Multiplexing), based on multicarrier transmission where total date stream is split into low bit-rate streams transmitted on several separate sub-carriers. OFDM is resistant to frequency-selective fading, supports varying spectrum allocations an easy to implement.

4G

In today’s mobile communication access to mobile networks and mobile services are controlled by a single operator. In 4G, access to mobile services will be evolved to an open mobile cloud. i.e. companies such as Microsoft, Oracle, Google can provide services to their users.

4G is based on OWA (Open Wireless Architecture). The OWA offers service-oriented architecture and infrastructure for mobile phone advancement.

Contiki (OS for IoT)

As IoT is being popular, technologies are being developed for it. Most of the electronics devices have chips embedded with them, they need basic software to run chips. Contiki is the OS for running chips of ‘things’ in IoT, just as we use Windows or Linux to run a computer. Contiki is designed to be compatible with smallest devices such as smart dust (tiny wireless sensors, which communicates a few bits of data).

Features

Contiki is a completely open source software. It can be stored in 10 kB RAM and 100 KB of ROM. It can run on ARM-associated devices or 8051 SoC. Since some standards are defined for public networking, more efficient and optimized protocols are supported e.g. Rime Stack, developed to optimize the ipv6 protocol.

For memory management, Contiki uses standard ‘C’ style memory allocation with malloc().

For communication management it supports both ipv4 and ipv6 stack implementations with smallest footprints. It also supports low-power variants such as 6LoWPAN (IEEE 802.15.4)

Several applications such as web browser, calculator, telnet client, email client, web server come as a part of Contiki.

Internet of Things

Towards a connected world...

Think about the future where you can operate home appliances from anywhere on the earth.

Think about the city where no longer need to wait for taxis and buses.

Think a country where transportation is going driver-less.

This future already exists..! 

This all are going to be possible via IoT.

What is IoT ?

IoT is the technology in which devices are connected through internet. IoT enables the automated exchange of information between devices or machines, and humans. The ‘things’ in IoT includes electrical appliances at home to the large machines used in factories. These things includes small wireless sensors which has low-power and low-memory characteristics, i.e. memory is measured in bits or bytes and power consumption is so low that devices can run for years with a pair of AA-size of battery.

Which OS used by IoT?

'Things', also called smart objects becomes a bridge between the real world and virtual worlds.They contains microprocessors, communication and power source. These all objects are controlled  by the operating system. 

Contiki is the operating system just like a Windows and Linux but used for very specific purpose and basically concerned with “things” in the Internet of Things (IoT).

In next blog we will go more deep about OS.

Review regularly for more detail.

Applications ( the IoT World!!!!!!!!!)

   Remote Control devices using mobile:

‘Connected home’ is one of the popular concept IoT.Belkin has launched several home automation products called WeMo that uses home Wi-Fi network to control through a mobile app.

Things you wish. That you had!!
