Smartphone innovation will increase with 5G

Smartphone innovation will increase with 5G

Innovation in cellular and other supporting technologies as well as in applications will sustain the rate of smartphone improvements.
Press and industry analyst response to the recent announcement of the iPhone 7 has been lukewarm. For example, The Economist notes the “main novelty” is it no longer has a conventional jack for headphones. That newspaper reckons “after almost 10 heady years, dating from the release of the first iPhone in mid-2007, both growth and pace of innovation have slowed markedly in recent months.” I doubt the pace of innovation is really slowing or that this could ever be reliably determined over months rather than years. However, in conclusion, The Economist also wisely rejects “talk of an end to the smartphone era.”
Improvements under the hood
Whereas some smartphone innovations are very overt and revolutionary; others are not so apparent to consumers and are more evolutionary, but are at least as significant. The multitouch capabilities included in the first iPhone were literally very tangible and enabled access to regular web pages, as opposed to the repurposed content hitherto required for small displays with WAP browsers. The iPhone transformed browsing on a small device connected to the internet via Wi-Fi, but remained hobbled as a truly mobile device – six years after the introduction of the first 3G networks – with only 2G cellular connectivity and a maximum downlink speed of only around 150 kilobits per second achievable. Uplink speeds were much slower still.
Performance has improved enormously over the last nine years. LTE data rates are 1,000-times faster – at hundreds of megabits per second in the downlink, tens of megabits per second in the uplink, and latencies have reduced from several hundred milliseconds to tens of milliseconds. Ever-higher maximum cellular data rates achievable in the uplink and the downlink on the succession of iPhone models illustrates the gradual yet relentless improvements in cellular technology. For consistency over many years, the following chart includes fastest downlink data rates in device testing on commercial networks or considered likely following announcement of each new iPhone model, as indicated in contemporaneous analyst and press reports. Maximum speeds depend on latest technologies in devices and in network upgrades, which can take a year or so to roll out. Actual speeds are also affected by a user’s location and radio interference with other users nearby. For example, AT&T Mobility’s customers in New York and San Francisco suffered with slow speeds and poor availability following the introduction of the iPhone 3GS in 2009. Such problems are rarely so severe these days.

Exponential growth in downlink speedsOther fundamental device improvements include the number of cellular standards and frequency bands supported. The first iPhone was a single-mode GSM/GPRS/EDGE device. Over the years, CDMA, TD-SCDMA, LTE-FDD and LTE-TDD have been added to make iPhones multimode devices. Multiple frequency bands are also employed with each standard. In particular, large and increasing numbers of bands are required for LTE. Since the introduction of the iPhone 5 in 2012, with support for LTE in up to five bands, the number of LTE bands supported has increased to 23 bands in the iPhone 7. Squeezing more and more modes, bands and other cellular functions into smartphones and getting higher and higher levels of radio performance out of them is no mean feat. It requires major innovative efforts and accomplishments in various ways.

A lot of inspiration and perspiration
Cellular technology developments have included some relatively large step-changes, for example, with new air interfaces; but developments mainly arise in a series of many incremental improvements. Even generational upgrades can take years to deploy across networks before benefits can be fully enjoyed. Until at least the turn of the millennium, cellular technology improvements were overwhelmingly in supporting voice and the most basic data capability imaginable with a maximum of 140 characters per text message. Since then, innovations have been focused on exponentially increasing speeds and network capacity for data. Numerous new technologies have been developed and introduced in the last decade. Terminology for these includes dual carrier, carrier aggregation, inter cell interference coordination, coordinated multipoint and heterogeneous networks among many others which have collectively boosted spectral efficiency, increased end-user data rates, increased network capacity and lowered latency.

The development of these standard-essential technologies is a massive coordinated endeavor involving numerous companies. According to analysis by Signals Research Group on 262,773 submissions to five 3GPP working groups from 1999 through December 2014, 43,917 documents were approved for inclusion in standards. The approved documents include 3G only, LTE only, and 3G and LTE documents as well as submissions that fall outside all of these three categories – documents pertaining to GSM/GERAN or IP multimedia subsystems are examples. More than an estimated 1 million man-hours is spent actually in 3GPP working group meetings each year. However, working group activity is merely the tip of the iceberg. Mobile communications sector research and development investment is estimated at up to $100 billion per year. Much of that is in development of standard-essential technologies including 4G recently, and now also in 5G.
‘You ain’t seen nothing yet!’

Each successive new generation of cellular technology has been driven by increasing technology developments, innovation and adoption by wireless carriers and consumers. Following the rather disappointing data rates and lackluster adoption of 3G W-CDMA between 2001 and 2005, the pace of all the above increased with the introduction of HSDPA from around 2006, and then increased again with the introduction of LTE from around 2010. Industry enthusiasm for 5G is also great and so we should expect the rate of innovation to be maintained, not diminish, with the expected introduction of 5G toward the end of the decade.


Whereas demand for 5G will be dependent on new applications such as those in artificial intelligence and augmented reality, some of those applications will only be possible by the improved performance such as ultra-low latency and ultra-high availability, as well as higher data rates that 5G communications promises. Many innovations and improvements will be required for new types of devices and services such as with the “internet of things,” but smartphones will also be in the frontline.

Analysis and Comparison of 1G, 2G, 3G, 4G, 5G and 6G Telecom Services

Until the controversial spectrum scams were brought up in the lime light many were ignorant of what 1G, 2G or 3G stood for and all of a sudden a hike was found out amongst laymen so as to be knowledgeable about it. Still a number of people are unaware of 1G or 2G when the world has moved on to 4G.

The telecommunication service in World had a great leap within a last few year. . 6 billion people own a mobile phones so we are going to analyze the various generations of cellular systems as studied in the evolution of mobile communications from 1st generation to 5th generation .Now almost all the service providers as well as the customers seek for availing these 3G and 4G services.

We can analyze that this could be due to increase in the telecoms customers day by day. In the present time, there are four generations in the mobile industry. These are respectively 1G the first generation, 2G the second generation, 3G the third generation, and then the 4G the forth generation. Ericson a Swedish company is launching this high tech featured mobile into the market. It is being first introduced in the Swedish Capital city, Stockholm.

Present Status of Telecommunication Services in Asian Countries

Now we are in the midst of 4G. In China, the 3G service came into existence only by last February. Therefore, that it may take time for exposing to other states. But we should also realize many other countries such as the Asian countries were using these services since last decade. Due to these reasons, we can hope that the 4G may enter within a few years. The 3G (Third Generation) had also reached India recently. There is no doubt that within a few years India will be the first in telecom users also.

What is 2G ?

Second Generation (2G) wireless cellular mobile services was a step ahead of First Generation( 1G) services by providing the facility of short message service(SMS) unlike 1G that had its prime focus on verbal communication. A typical 2G G.S.M network service ranges from 800/900MHz or 1800/1900 spectrum. The bandwidth of 2G is 30-200 KHz.

Let us examine what these 3G & 4G have rather than that of 1G and 2G.

Analysis of 1G and 2G services

In 1G, Narrow band analogue wireless network is used, with this we can have the voice calls and can send text messages. These services are provided with circuit switching. Today’s the usual call starts from the beginning pulse to rate to the final rate. Then in case of 2G Narrow Band Wireless Digital Network is used. It brings more clarity to the conversation and both these circuit-switching model.

Both the 1G and 2G deals with voice calls and has to utilize the maximum bandwidth as well as a limited till sending messages i.e. SMS. The latest technologies such as GPRS, is not available in these generations. But the greatest disadvantage as concerned to 1G is that with this we could contact with in the premises of that particular nation, where as in case of 2G the roaming facility a semi-global facility is available.

2.5 Generation

In between 2G and 3G there is another generation called 2.5G. Firstly, this mid generation was introduced mainly for involving latest bandwidth technology with addition to the existing 2G generation. To be frank but this had not brought out any new evolution and so had not clicked to as much to that extend.

What is 3G Generation

But to overcome the limitations of 2G and 2.5G the 3G had been introduced. In this 3G Wide Brand Wireless Network is used with which the clarity increases and gives the perfection as like that of a real conversation. The data are sent through the technology called Packet Switching .Voice calls are interpreted through Circuit Switching. It is a highly sophisticated form of communication that has come up in the last decade.

In addition to verbal communication it includes data services, access to television/video, categorizing it into triple play service. 3G operates at a range of 2100MHz and has a bandwidth of 15-20MHz. High speed internet service, video chatting are the assets of 3G.

How is 2G different from 3G?


  • In comparison to 2G customers will have to pay a relatively high license fee for 3G.
  • The network construction and maintenance for 3G is much expensive than 2G.
  • From the point of view of customers, expenditure will be excessively high if they make access to various facets of 3G.

What is Packet Switching

This is actually done by supplying various addressed packets, which will be interconnected to have the conversation. It is not necessary to create a new dedicated path for sending the data. It had been modified in such a way that the data can be send through any path; hence, this data will be received at a less time as compared to that of voice calls.

Packet Switching in Computer networks

The data packs are also used in computer that is when we connected with internet this data pack helps to download the web pages that is being displayed in the monitor. For a Data Pack it does not need any separate path for downloading or displaying any objects in the computer or any other equipment. This is due to the reason that by networking, separate paths are being created and after analyzing each, the data are being transferred to the correct access point.

Main 3G Services

With the help of 3G, we can access many new services too. One such service is the GLOBAL ROAMING. Another thing to be noted in case of 3G is that Wide Band Voice Channel that is by this the world has been contracted to a little village because a person can contact with other person located in any part of the world and can even send messages too. Then the point to be noted is that 3G gives clarity of voice as well can talk with out any disturbance. Not only these but also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, Multi Media Messaging Service (MMS), 3D gaming, Multi-Gaming etc are also available with 3G phones.

Main 4G Features

When It is still to estimate as to how many number of people have moved on from 2G to 3G , technology has come up with the latest of its type namely 4G.A successor of 2G and 3G, 4G promises a downloading speed of 100Mbps and is yet to shower its wonders on. then with the case of Fourth Generation that is 4G in addition to that of the services of 3G some additional features such as Multi-Media Newspapers, also to watch T.V programs with the clarity as to that of an ordinary T.V. In addition, we can send Data much faster that that of the previous generations.

What is the reason for delay in implementing 3G and 4G Mobile services?

It is very sad to say that the 3G services had only reached with in some towns of china, so that it may take time to reach to Other countries. Another major defect of this is that Wide Band Frequency Spectrum, which is needed for 3G, is lacking. Another reason for this is that it a cost bearing item especially for sending data. So for us it is a higher one which could be used only by upper classes. If it should be accepted among all customers, firstly it should be availed at a lower rate, for which the rate of spectrum should be declined.

What is 5G Technology

5G Technology stands for 5th Generation Mobile technology. 5G mobile technology has changed the means to use cell phones within very high bandwidth. User never experienced ever before such a high value technology. Nowadays mobile users have much awareness of the cell phone (mobile) technology. The 5G technologies include all type of advanced features which makes 5G mobile technology most powerful and in huge demand in near future.

The gigantic array of innovative technology being built into new cell phones is stunning. 5G technology which is on hand held phone offering more power and features than at least 1000 lunar modules. A user can also hook their 5G technology cell phone with their Laptop to get broadband internet access. 5G technology including camera, MP3 recording, video player, large phone memory, dialing speed, audio player and much more you never imagine. For children rocking fun Bluetooth technology and Piconets has become in market.

What is 6G technology ?

1. Increase performance and maximize your data throughput and IOPS
2. Protect your system and secure your data
3. Ease your service and build efforts and expand your data center configuration options

The 6G technology haven't been fully revealed yet but the search phrases like what is 6g mobile technology, 6G technology, 6G mobile, 6G network, 6G wiki, 6G technology ppt are getting more familiar with new mobile technology getting evolved. The Google hot trends has rated the term 6g as the 17th most searched word in the search engines. iPod nano 6G is available in 8GB and 16GB versions and carries the price tag of $149 and $179 respectively.
