Google Brings A Modular Smartphone and Change The Concept of Smartphone

Google Brings A Modular Smartphone.

It’d be the last phone you ever needed to buy, because you’d be able to swap out everything from the camera to the display to the battery, in order to always have the exact phone you want. Google, the goal is to build a device that will make the Smartphone accessible to the billions of people who can’t afford iPhones and Galaxy S5s.

Modular Smartphones are more than just a Lego-lover’s pipe dream, it could change the industry forever. New types of manufacturing, new ways of buying and selling phones, and new ways for consumers to interact with their most personal and most intimate devices.

অনেকেই মুঠোফোন থেকে ওয়েবসাইট দেখতে (ব্রাউজ) অপেরা মিনি ব্যবহার করেন। অপেরা মিনিতে প্রায় ওয়েবসাইট দেখার ক্ষেত্রে গতি অনেক ধীর থাকে। তবে চাইলেই এটি দূর করা যায়।

অপেরা মিনি ৪.০-এ দ্রুত ওয়েবসাইট দেখতে MenuTools নির্বাচন করতে হবে। এবার Settings-এর একেবারে নিচে Network থেকে Socket/HTTP বা Socket নির্বাচন করে দিতে হবে। শুধু Socket নির্বাচন করলে দ্রুতগতিতে ব্রাউজ করা যায়।

অপেরা মিনি ৬ এবং এর পরের সংস্করণগুলোতে একই নিয়মে Socket/HTTP নির্বাচন করা যাবে না। এতে অন্যভাবে করতে হবে। এ জন্য শুরুতে অপেরা মিনি ৬ সংস্করণে Menu থেকে O Symbol নির্বাচন করে Settings-এ যান। এবার Settings অপশনের নিচে Advance থেকে Protocol-এ ক্লিক করে Socket/HTTP থেকে Socket/HTTP বা Socket নির্বাচন করুন। এই কাজগুলো করে অপেরা মিনি বন্ধ করে আবার চালু করতে হবে। এবার দেখুন ফেসবুকসহ অন্যান্য ওয়েবসাইট খুব দ্রুত ব্যবহার করা যাচ্ছে।

Mobile phone celebrates | 40th anniversary

_66724793_66724792The first mobile phone call was made 40 years ago today, on 3 April 1973.

Martin Cooper, a senior engineer at Motorola, called a rival colleague at another telecoms company and announced he was speaking from “a ‘real’ cellular telephone”.

In 2012 a report carried out by the International Telecommunication Union found that there were six billion mobile phone subscriptions worldwide. At the time the global population was seven billion.

Phone father

Martin Cooper, now aged 85, is renowned as the “father” of the mobile phone.

In a previous interview with the BBC he admitted he thought the initial cost of the devices (in 1983 the first models cost $3,500, or £2,300) might be prohibitive to the mobile phone becoming a mass-market product, but he did recognise that the hefty handsets would probably shrink. “We did envision that some day the phone would be so small that you could hang it on your ear or even have it embedded under your skin,” he said.

Mr Cooper said his vision for a mobile phone was first conceived in the late 1960s when the car telephone was invented by AT&T. He wanted to create “something that would represent an individual so you could assign a number not to a place, not to a desk, not to a home but to a person,” he said.

“It pleases me no end to have had some small impact on people’s lives because these phones do make people’s lives better. They promote productivity, they make people more comfortable, they make them feel safe and all of those things,” Mr Cooper added.

He was also pleased to have been one step ahead of the competition. “When you are a competitive entity like we were, it’s one of the great satisfactions in life,” he said.

The DynaTAC 8000X, Motorola’s first commercial handheld cellular phone, was launched in 1983


In this new generation world, International Telecommunication Union [IT U] research that there are 530 Core cell phone User in the world. This small device CELL Phone easy our life. But more person not know, who is the creator of this CELL Phone?  at first cell phone create Martin Cooper. In 1950, Martin Cooper earns the Electrical Engineering Degree from the Eleneos Institute of Technology.

How get idea to create this Cell Phone ::

When Cooper was doing service in Motorola, Personal Communication Department, then he was saw talk in telephone by wire. That time he was thought how to remove the wire from his telephone system. Also, on that time, he was doing start to research, how should do use the wireless technology. In the same time, United States of American top listed Technology Company AT&T was created a radio telephone system “ CAR  TELEPHONE. ” but that time AT&T’s CAR TELEPHONE fail to get customer satisfaction & COOPER’s “Handheld Mobile Phone” get more satisfaction & spread in local & International market.

Cooper all time says to new generation does something “Out Of The Box”. Also he says do more research for create something & give more importance on the research. Cooper say maximum institutions, organizations do research in limited time but that is not helpful to develop for that organization. He all time say to everybody that the Research best place is University, because in the University have many opportunity to do research on different subject. In the University time is the best real time to do research. That’s why in the student life, New Generation should do more research. Also, Martin Cooper is the Icon of technology world. Onetime a person ask a question to Martin Cooper how should be get success.
