A Brief Introduction
The advancement of human civilization has been marching on the back of technological evolution. Each successive generation of mankind has created a technology which would suit its own stage of development. We have had a Copper Age, Bronze Age and an Iron Age. The Second World War ended with the beginning of the Nuclear Age. This, in turn, gave way to the Telecommunications Age. 5G is a term that signifies the progress of successive generations of Telecommunications. The First mobile phone call was made way back in 1973. The advent and progress of mobile phones have completely transformed the world we live in. The term 5G is a combination of a Numeral and an Acronym. ‘G’ stands for ‘Generation’ and the Numeral 5 indicates the stage of advancement of successive Generations of telecommunication technology. 5G technology will offer unprecedented speeds allowing users to utilize network technology in new ways from online shopping to browsing popular hookup sites and adult dating apps. Picture browsing Free Fuckbook or your favorite hookup app while telling your computer to purchase movie tickets for you all at the same time with ease. This will revolutionize industries from dating and romance to ecommerce and housing.
Each Generation has been epochal. The First Generation or 1G, as it is now known, was launched by NTT (Nippon Telegraph and Telephone) in 1979 in the capital city of Japan, Tokyo. Intensive coverage of the entire country of Japan by the 1G network was achieved by NTT within 1984. Other major countries, particularly the USA, noticed and understood the significance of the development by which young post-war Japan had set the standards in Telecommunication, to be followed by the rest of the world. The first American 1G operation was approved in the US in 1983. This was started with government approval of Motorola’s DynaTAC. Within a few years, the other advanced countries such as Canada and the UK had introduced the 1G network in their own countries.
The initial 1G technology could be faulted on several accounts. Apart from the rate of transfer of data, which peaked at 9.6kbps (kilobits per second) during this generation, and may even be considered as laughable today, there were many other problems. Spreading the coverage was a painfully time-consuming process and so sound quality was either interrupted or quite low. Different systems operated on different frequency ranges, and so could not offer standard roaming support. Intrusions and Hacking were both easy and common since the calls were not encrypted. But the popularity of 1G, in spite of the high price tags of DynaTAC (nearly US$ 4000 then, and valued at US$ 10,000 now), kept growing astonishingly. By 1990, DynaTAC alone had 20 million global subscribers. It is important to understand the performance of these earlier generations, in order to understand — What is 5G?
The 2G Social Revolution
The lessons learnt during the upward arc of 1G were encapsulated in a new standard, launched in 1991, by Finland. Many changes and developments were now included as standard. Digital Voice Calls was given a cloak of protection from external intruders, by Encryption. Digital Voice Calls were themselves made much clearer by the elimination of background, static and noise. The data transfer rate was also increased to the then astonishing rates of 40kbps. The analogue beginnings of 1G were totally replaced by digital techniques only, which not only allowed the speeds to rise sharply but also provided clear and error-free transmission of voice and data alike. Near its peak, the 2G transfer speeds were augmented by Edge Connections, in which speeds of up-to 500kbps was possible. Suddenly, the whole world was competing to adopt the 2G system, and not just technologically, but culturally the world was facing a new revolution. Telecommunications across the world was changed forever.
The Next Revolution – 3G
2001 marked the beginning of 3G. NTT DoCoMo of Japan introduced new and complete standards to be used by vendors as the network protocol. Web connectivity was standardized. Data could be transferred across any location continuously as ‘Data Packets’. International Roaming services were at last available to Users everywhere. Data transfer rates increased immediately to around four times faster than 2G. This sudden increase in data transfer led to the simultaneous introduction of services such as Video Conferencing, Video Streaming and VOIP (Voice-Over Internet Protocol). A typical example is Skype. The introduction of Blackberry and its powerful support as a personal business aid typified the 3G era. Apple entered the scene in the closing stages of 3G. In 2007, Apple first introduced network capabilities that were never even dreamed of before.
The Age Of Streaming – 4G
4G first entered the global picture in 2009. It was introduced as the LTE (Long Term Evolution) Standard for 4G, simultaneously in Oslo, Norway and Stockholm, Sweden. Extraordinary speeds of up to 1 Gigabit per second were now possible for stationary Users. High-quality video streaming was available for all. Gaming services and Online Gambling mesmerized entertainment seekers internationally. HD videos created new perceptions both in business and in person-to-person communication. HQ video conferencing transformed world business. Minimum data rates of 100Mbps (LifeWire) was a massive jump from the 2mbps for 3G. It was a complete redesign of the 3G network architecture.
The Future with 5G
2020 will see the introduction of 5G. The target speeds for future 5G are a minimum of 1Gbps with a possible peak of 10Gbps. Power requirements at the same time should reduce rapidly, along with enhanced storage of data in the Cloud. Interconnection of vast numbers of devices and to the Internet will include a newly identified environment, which is now loosely being called ‘IoT’ or Internet of Things. IoT will enable extreme remote control of devices, intelligent homes and AI (Artificial Intelligence) driven offices. Stable robotic control through the Internet, with encrypted commands, will become commonplace. Massive storage of data with security safeguards in position, to prevent hacking, will be fully in use. Cloud computing will increase the power of individual operators enormously. Overall development and change in core functionality will be observed with extremely high dialling speeds, data transfer speeds and multiple device connectivity. This will be an era that will be knowledge-driven, instantaneously across the world, and the inter-stitching of the Web community into one whole technical and social establishment. Cloud computing, AI and IoT will combine together to completely redefine the world in the next few years, thus answering the question – What is 5G?
BEST VR HEADSETS – LOOKING AT VIRTUAL REALITY
Man has been pondering on Reality, ever since he first realized he was gifted with Consciousness. Sages have meditated on Reality and imbued it with mystical qualities. Religions have proclaimed it as an illusion, or “Maya”, or, at its other extreme, the Only Truth. Alchemists in the ‘Middle Ages’ have considered Reality as transmutable, but, until the Nineteenth Century, Scientists have considered Reality as immutable. In the Arts, the aim has always been to copy Reality, and Engineering with its sister Architecture has always based itself solidly on Reality. Reality has been defined as the totality of a system, known and unknown, in physical terms. It is existent, it can exist without the presence of the observer, and it does not belong to the world of the imagined or dreamed, or even visions. But “Virtual Reality” is a concept that has haunted mankind since the early days.
VR, or “Virtual Reality”, is the simulation of Reality by the use of modern technology. Reality itself has seemed ever far away, what with the concepts of the Real as proposed by the latest scientific theories, like the String Theory, The Big Bang and The Expanding Universe. But a near-perfect copy of Reality has been looming ever closer, what with progress in the latest electronic and optical gadgetry, coupled with extreme miniaturization.
The market is now full of optoelectronic wearable, in the form of Headsets, all claiming to gift the buyer with VR. But sadly, only a few make the cut. Sensorama was invented in 1957 but was not patented until 1962. This consisted of a viewing screen within an enclosed booth displaying stereoscopic dynamic images. Since then, VR Headsets have improved gradually, with each leap of scientific advancement, until the present day. This is, therefore, a study of the Best VR Headsets on the market at present, with a review of their most attractive features.
Dreams of Reality
A VR (Virtual Reality) Headset is an Optoelectronic device mounted over the eyes, generally secured with a belt, which simulates reality for the Wearer. Apart from general entertainment, VR Headsets are used for Medical and Psychosomatic Therapy, for Education, for Video or combined Video Audio Gaming, for Scientific Research, as Reality Simulators, for Training and many other applications. This is a pseudo-reality, however lifelike it may seem, and may have no relation at all with the actual surroundings or environment of the Wearer. Sometimes Traumatic Events are recreated for Patients, as Therapy. VR Headsets can provide a safe and controlled environment for patients suffering from anxiety and fears, phobias and depression. When used for Gaming, Video is sent from the Console, PC or mobile handheld device like a Smartphone, to the VR Headset. Of course the area of VR that can’t be ignored is adult entertainment and adult content. Of course pornography is a large interest, but adult platforms like Local Sex App have chosen to use VR technology to focus on peer to peer interaction for “virtual casual sex” taking a very innovative approach when compared to other top hookup sites. Of course VR lends itself naturally to gaming so the emergence of adult erotic gaming has spread to the VR space as well. The VR Headsets use two LCD displays (one for each eye) or two feeds sent to one display to create a lifelike illusion of Reality for the Wearer.
When Reality Knocks
Virtual Reality comes in two types: Fully Immersive and Non-immersive. Medical Treatment of mentally affected Patients often uses Fully Immersive VR, in order to use the Unconscious mental state to affect the cure. On the other hand, VR Flight simulators are Non-immersive, to allow the Trainees to communicate with their Trainers while receiving VR Training. Other subsidiary types are AR (Augmented Reality), CR (Collaborative Reality), and WR (Web-based Reality). Some of the benefits of VRT (Virtual Reality Training) are as follows:
- Realistic Scenarios, at little or No Risks.
- Safe and Controlled Area.
- Can be Remote Controlled, thus saving time and money.
- Simplifies complex problems and situations.
- Different Learning Styles can be accommodated, with excellent retention and recall.
- Innovative and Entertaining
The Market Spread
Virtual Reality Headsets dominate today’s markets. Some of the Best are as follows (classified by Manufacturer):
- OCULUS Brand provides some of the very Best VR Headsets. The Flagship Product is the OCULUS QUEST. A mid-priced device at around US$ 400, it has a tracking self contained and 6 Degree of Freedom (DoF) motion controls, complete with vibration along with finger movement tracking used on the OCULUS RIFT for PC gaming. Extremely high Resolution, large touch controller, wireless, self-contained and very comfortable design overcomes its limited App library (at present, but growing) and non-compatibility with larger mobile / Windows ecosystems. The OCULUS RIFT S is an install PC set, with 1280 X 1440 per eye VR display, room track which is self-containing vide 5 cameras studded in the Headset, making sensors or external cameras redundant. OCULUS GO is a fine, basic, sitting-still Device with a sharp and convincing display, at only about US$ 200 a unit.
- VALVE INDEX is an amazing PC controller, with “knuckle” (pressure –sensitive) controllers which track all the five fingers. Superb Audio and wide view come with a refresh rate of 144, 120, 90 and 80 Hz. This device works well with hardware Vive, which reduces setup costs sharply since this device is quite expensive, tethering cable and requires the setup of a room.
- HP REVERB is easily the best work Headset. These sets, which are designed by Microsoft, use WMR headsets (Windows Mixed Reality) using tracking inside-out and don’t need camera sensors. Prices start at only about US$ 200, but the REVERB (priced around US$ 650) has a powerful resolution of 2160 X 2160 per eye, a 90 Hz refresh rate and is very comfortable on the eye.
- HTC VIVE is STEAM VR compatibility, and facilitates with library as VIVE and is in the same price class.
The Future looks very bright for VR Headsets. The market is expected to reach US$ 38.7 Billion by 2024, with a CAGR of 41.0% from 2019 to 2024. The main focus areas of Virtual Reality content will be sports, gaming, and entertainment. Demand will keep growing for Health Care, and Retail Services. Military applications are also growing rapidly, and may even overtake other prized areas. The introduction of AI (Artificial Intelligence) incorporated VR Headsets look poised in fact to overtake all other applications. The Best VR Headsets are yet to come.
You can’t go anywhere without hearing about a virtual home assistant. These devices have revolutionized activities and tasks in the home and are found in homes throughout the world. From playing music, to ordering supplies the things these devices can do are amazing. They of course have their limits. They cannot create picture perfect organization in your home worthy of a Pinterest post. For that you will still need a professional organizer. However, organization and high function is easier to maintain thanks to the virtual home assistant. So which one should you get?
Earlier, the price was one of the considerations to compare devices from two companies. But today, the price cannot be considered as a measure since one company keeps their product price a little lower than the other or they just go hand in hand. Especially when you compare the products from companies like Amazon and Google then are usually on the line.
Even in this case, when we start comparing Amazon Echo Dot and Google Home Mini, there is not much difference when we think of the price. The main reason behind this is, both the companies are ready to enter your home and they are desperate in entering into all kinds of device markets. In tech, there are many things going to happen in upcoming years and most importantly there will be competition in home automation devices and voice assistants.
What You Should Do
It is true that finally, you will end up buying one product from a company. But, before that, you can spend time in comparing similar products from different companies. You need to compare the digital assistance they are offering, their capabilities, and the hardware. Apart from this, you can compare the way they work and do things such as controlling other smart devices and playing music.
Moreover, there is one more thing you need to check before Amazon or Google. It is about who you trust when it comes to your data. Google is always behind making things attractive to its target users. Whereas, Amazon always thinks about your needs and it wants to get information about your life so that it can bring relevant products.
Google Home Mini vs Echo Dot The Hardware
- Echo Dot from Amazon and Home Mini from Google are released in the almost same size. But, the latest release of Echo Dot is a little bit taller than Home Mini. Echo Dot is a gadget released in hockey puck shape. It comes with a fabric cover that covers it from the bottom and sides as well. if you look at Home Mini, it hides the touch-sensitive controls by a dome fabric.
- Echo Dot is released in pleasant light gray, off-white, and dark gray colors. Google Mini is available in coral, charcoal, and chalk colors.
- When it comes to connections, the barrel connector is used by Echo Dot for connecting to the power supply. Whereas, Home Mini you can use a USB power supply.
- Full-time power supply connection is the need of both these devices
- Both these devices can get power from any third-party battery dock
- When it comes to location and space, both are highly flexible and they can get into any low profile fit
The smart speaker can be placed in the room of your choice. Even though you can place it in the room where you listen to music more often, you can place it in any location. Both these devices are good at receiving commands.
The mute button is present in both these devices and through this, you can easily disable the mute buttons. But, it is better to keep the mics active all the time since you can issue voice commands. In case if you have plans to use the mute button on a regular basis, then you should go for Echo Dot. The reason is, the button is available right at the top and it is convenient. In the case of Google Home Mini, they have placed the mute button on the backside. So, whenever you try to hold the device steady for operating this button it can alter the volume controls as well. This design is created thinking about seldom use of the mute button.
Both the speakers make you use their wake word. In the case of Amazon, it is Alexa and Hey Google is for Home Mini. In both cases, the voice command is sent to the cloud service and there it gets interpreted. For Google Home Mini you can also make use of ok Google command. In Amazon devices, there is an option to set the command of your preference. You are given more options like you can change the command to Computer, Echo, and Amazon.
Both these devices offer another feature and that is about reviewing your history of commands. You can listen to the audios and commands which are picked by the speaker. If you wish, you can also delete the commands.
When it comes to digital assistants, there is a major difference between these two speakers, Google Assistant and Amazon Alexa. Both these are evolving constantly and they are adding features on a regular basis. Hence the comparison will be on the current features and the evolution can change them anytime. Apart from these, when it comes to ordering commands, Amazon Alexa is the best choice. But when we consider other things like general search and even information updates, Google always leads. So, when we think about controlling other devices, they both are perfect and similar.
Earlier, the majority of the people were interested in televisions and they were satisfied with them. But when it comes to imagining home theater, buying bigger television projectors. Today, projectors have become very common and when we think of home theater we think of short-throw projectors.

Homes In Search Of Smartness
Homes, meaning habitats, have been around as long as mankind. In fact, all living beings are forever in search of good homes. Home is simply a safe and comfortable environment, where one can rest at ease, without the harsh, conflicting and sometimes treacherous realities of an external world. Home is where keepsakes and personal properties can be stored and displayed conveniently. Home is where an individual or family comes to at the end of the day, to find nourishment, rest, entertainment and peace. Traditionally, people rested at home, and went out to work. But this is the age of SOHO, or “Small Office Home Office”. People are not only bringing home the work, they now plan not to leave home to work. In the digital age, work comes home to people, via the network. Of course, lots of others still have to go out to where the work is. But the heart is still at home. It is known commonly that most people in factories spend some time at work, particularly during “off periods”, thinking about home, and sometimes worrying about home. But this is an extraordinary age, where AI (Artificial Intelligence) is beginning to convert our traditional non-living homes into sentient beings. People at work are slowly shifting away from “home help” and subordinate staff to take care of domestic jobs. “Smart” homes are beginning to take over, turning homes into intelligent automated and self-controlled habitats that can operate the greater part of a day on their own. amazing smart home devices have made this unbelievable scenario almost possible.
What Makes A Home Smart?
Smart homes use extraordinary components to create a controlled environment. These components complement and supplement each other to create a system that can look after its inhabitants in comfort, and sometimes even look after itself. After working hard during working hours outside, people can return home to have most of their home needs taken care of at source, without having to waste quality time on mundane, time consuming, day to day and routine tasks. These are tasks which can be listed by experienced householders and are mostly repetitive. And so, sophisticated programs can be extracted by brilliant developers, with the aid of the latest software systems, to simulate human handling of standard home situations. It should be noticed here that it is the Whole System that needs to be “Smart”, not the individual components, which must only fulfill their individual duties perfectly. For example, if the system, after the entry of a human inhabitant, commands a door to be closed, the actual device closing the door, which may be a motorized door closer, need not be “smart”. It should only be able to close the door efficiently. They must also be able to communicate with the System, and act on command. While performing a task, the device should also be able to give a scaled feedback to the system, which will be used regulate the reaction to achieve the objective smoothly. Speed of operation too will be dictated to the Device, as will other necessary instructions to complete the task. Thus, a class of amazing smart home devices have been invented, that individually may be able to perform only repetitive jobs, but can be used as the sensory and muscular extremities of the system that replaces the householder.
What Devices Make A Home Smart?
Smart homes have smart systems. Devices may or may not be smart in themselves, but must be able to perform complex tasks for which they were designed, but without problems or delays. Fault diagnostics must be installed, to pre-warn both the system and the householder. Thus, some devices are converted to smart devices by the conjunction, and reports f of electronic gadgets that can obey commands by the main system to perform the tasks set by the System, feedback the results continuously in line with previously set standards or scale as and when they occur. So the complete Home Automation System, or HAS, consists of a Central Control System which uses modern control techniques and software to take charge of a complete habitat, along with peripheral devices, consisting of sensors and Activators, some of which may be smart themselves, and control their own domains, but continuously report to the Main HAS.
Amazing Devices For Smart Homes
Some amazing devices for smart homes are as follows:
- LG has just released their latest technology for Smart Homes called ‘Thinq’. This has Smart Access devices in the system which allows the Homeowner to take remote control of various functions. While still outside the home, the Owner can set temperature and humidity levels at the house, adjust lighting, and so on. House cleaning by LG’s HOM-BOT robotic vacuum cleaner can be remote controlled, areas or whole of the house can be viewed, perhaps on a mobile smart phone, or even feed the dog and water the plants.
- Lifewire’s Smart Microwave can be operated directly from remote locations, to cook food that has already been placed in it, according to menus set either by the remote house-owner or according to set menus as chosen, with complete step control from beginning to finish, and kept warm waiting for the owner to return. Connectivity with the HAS installed allows it to act inside the System jurisdiction, or independently, as desired.
- Smart Plugs (KASA) is commonly used easy control of appliances, energy monitoring, and home security automation. They can make even the dumbest appliance controllable, through an App. They are used to turn on and also control the level of Lighting, Music and Video Devices like TV, Video Streaming Devices etc. at home without direct intervention according to pre-set directions or remote instructions. Nest Learning Thermostats are Smart Plugs that take over complete charge of Temperature and Humidity in Households.
- Amazon Echo is an all-in-one smart Home Hub, which belongs to a class of Smart Home Devices to take over control and management of homes. There are a number of amazing devices like this in the market now.
