Tring Tring…… Tring Tring…… Mobile Phones…….
Smartphone. Imagine this word as a question to ask in 70’s or 80’s! What would be the answer? If I was asked this, I would say, “Smartphone is a Smartphone”. Now in 2018, it is hard to find a guy who cannot answer the same question. Well, credit goes to technology, it gave us not only mobile phones but also the answer of my question. Today we are going to have a visit to the history of mobile phones from late 50’s to present.
The concept of remote communication was given in early 1990. Just after the invention of radio. We cannot describe the need of mobile phones at that time but we can give you some idea about the grand grand grandfathers of smartphones.
Radio Telephones Of 1950:
AT&T were one of the first to popularize portable media transmission in 1947. The administration referred to just as “Cell phone Service” (MTS) spread to in excess of a hundred towns and thruway ways before the year’s over. The administration depended on an administrator to associate both approaching and active calls.
The mobile phones utilized were not especially convenient and utilized a half-duplex “press to talk” framework where the guest would need to discharge the catch to hear the other individual. That extremely same year two Bell Labs engineers proposed the establishments for the advanced cell organize. At the time the plans were brave, and it took until the 1960s for the plans to be actualized and significantly longer to come to advertise.
MTS was used in North America until the 1980s, despite AT&T’s introduction of the aptly-named Improves Mobile Telephone Service (IMTS) in 1965. IMTS was still mobile telephony in its infancy however, and was limited to 40,000 subscribers nationwide. In New York city, 2,000 customers shared 12 radio channels which on average took 30 minutes to place a call.
The First Wireless Telephone:
In 1960 the world’s first completely mechanized cell phone was presented in Sweden. The framework took into consideration robotized association from a rotational handset (that is the roundabout dialing handle to me and you) mounted inside an auto, however required an administrator to forward calls. The framework was known as Mobile Telephone framework A (MTA) and was supplanted by MTB two years after the fact.
At the same time, The arrival happened of Motorola which is holder of many first things. It started to make some telecommunication tools and became very famous among crowd. Then after some business, they started to make some revolution in communication industry, making first mobile phone in 3rd April 1973. The interesting thing about this was it is wireless and portable. Specs: 1.1 kilograms (2.4 lb) and measured 23 by 13 by 4.5 centimetres (9.1 by 5.1 by 1.8 in). The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.
The inventor was one of the researchers of Motorola. His name was Dr Martin Cooper.
Analog Cellular Networks or 1G:
The original of cell systems prepared to the systems we know and utilize today. Utilization of numerous phone tower destinations, each associated through a system, enabled clients to movement and even switch cell towers amid a call. It was an unrest based on existing, simple innovation with the first being worked in Chicago in 1977.
Known as the Analong Mobile Phone System (AMPS), it was built by AT&T and it took the FCC 11 years to approve AT&T’s initial proposal in 1971 before they were assigned the 824-894MHz range on which to operate AMPS.
Hot on the heels of the western researchers were Japanese telecommunications company NTT who built their own network in 1979. Five years later it was the first 1G network to cover an entire country. Then came the Nordic Mobile Telephone (NMT) network in 1981. Operating in Denmark, Sweden, Finland and Norway, it was the first to feature international roaming.
Digital Cellular Networks or 2G:
It is quite a simple that by time people wanted their life to be more improved. So what would be the better way then improving the cellular network. That brought European GSM and North American CDMA technology which brought 2nd Generation of Cellular Networking. Some few of mobile phone manufacturer started to make 2G Cellphones that time. And Remote Connection started to grow rapidly.
Another advancement made possible by 2G was the introduction of SMS messaging, with the first computer generated SMS sent in 1992 in the UK. A year later in Finland, the first person-to-person SMS delivery was using GSM technology. As popularity grew, pre-paid mobile phones and plans emerged in the late 1990s which further popularized SMS amongst all ages.
Mobile Broadband or 3G:
In 90’s demand of internet started to increase. People used internet in some heavy computer then. So a Japanese company named NTT DoCoMo launched 2G Cellular Network in 1999. Soon they realized 2G wasn’t enough. In 2001 they started 3G mobile broadband which was way faster than 2G. It made a great crowd among people because they had internet in their hand and it was fast.Many countries followed suit in the following years including South Korea, the US and the first European 3G networks which sprang up in the UK and Italy in 2003.
While 3G was still being developed a number of “2.5G” services appeared in an attempt to bring older technologies up to speed. Unfortunately speed was the lacking factor, and while technologies like GPRS and EDGE provided improvements over standard 2G, they did not match the speed of existing 3G technologies.
3G transformed the mobile phone industry and enabled widespread mobile Internet and the transmission services like TV and Radio for the very first time. Handset manufacturers jumped on the bandwagon and smartphone use took off. By around 2005 3G had evolved a step further, leading many to coin the terms “3.5G” “turbo 3G” and “3G+” in reference to HSPDA (High Speed Downlink Packet Access), HSPA and HSPA+.
Native IP or 4G:
Technology develops, our requirement increased. When 2G was not enough, everyone wanted next generation of network. After that 3G wasn’t the biggest deal, so people wanted a network in people can browse internet, download files and so on faster than ever. So 4G came in the field and made success.
While no official standards exist for 4G, a few technologies have laid claim to the title. The first was WiMAX, offered by Sprint in the US but perhaps the most successful has been LTE, which is popular also in North America but non-existent in some territories such as Australia. 4G marks the switch to native IP networks, bringing mobile Internet more in-line with wired home Internet connections. If we talk about present, it now an important matter which is 5G.
Time passed, Cellular Phones became Smartphones, our life became easy, communication is now in our hand. Even it is not so far from that day when……. You Know That.
