History of Mobile Phones

The Electromagnet was invented in 1825 by William Sturgeon, a British electrician. This was followed by the invention of the electric telegraph by Samuel Morse that transmit electrical signal over wires and is translated to message. The Telephone, a device that could transmit speech electrically was invented by Alexander Graham Bell in 1876.
Radio technology began as wireless telegraphy in 1866 by Mahlon Loomis, an American dentist. The Radio, a two way communication device developed from the permanent installations in vehicles to bag phones and the backpacked walkie talkie developed by Motorola in 1940s to hand held two way Handie talkie (HT) It was the size of a man’s telephone and Radio technologies combined to bring Radio Telephone.Radio telephone appeared in Europe in1926.
Soon, it was realized that when mobile phones are connected to smaller and lower powered base stations arranged in cellular pattern and with frequency reuse there is an increase in the number of people who can talk at a time i.e an increase in the traffic was how the cellular phone started in 1947. The electronics of cell phones was developed by Richard H. Frenkiel and Joel S. Enjel of Bell lab in the 1960s.
Most phones were analog in the 1980s. They are mostly digital now with ease of signaling,lower level of interference and increased capacity.
GSM (Mobile System for Mobile communication)
Lack of standardization for the various systems developed resulted in compatibility problems especially with the development of Radio technology. To address this problems, GSM, a standardization group was established in 1982 to create a common European mobile telephone standard that would formulate specifications for a pan European mobile cellular Radio system. It was hoped then that other countries would join the partnership.
FURTHER DEVELOPMENTS.
1G (First generation) These were analog, used for voice calls only.
2G (Second generation):These were digital, provided caller identity, text messaging, avoid interference and drop calls and could handle a large number of calls.
2.5G Between 2G and 3G. Provided faster services than 2G and can access the internet.
3G Suitable for high speed data application, traditional voice calls, provide navigational maps, web browsing, fax, paging, email, video conferencing, multimedia, TV streaming.…

Remote Backup – The Latest Data Backup Information For Business Owners

In today’s world, many things are uncertain; how your company will fair after a disaster occurs does not have to be. The numbers are in and the research has been conducted. Over 90% of businesses that lose their data for ten days or more end up filing for bankruptcy within the subsequent year. Initial response to that statement is, “It will not happen to us.” Yet, the research contradicts that because 20% of small to midsized business will encounter some sort of disaster, every five years, which causes data loss. This can be anything from a fire or a flood, to a power outage or a leaking pipe or air-conditioning duct that drips on to your servers, to a glitch in your software that causes your servers to malfunction.
So now the question becomes, what is the best way to ensure that our data is being properly backed up, and is it easily accessible to the organization in an emergency? Currently, the common practice is to backup servers and other important information to tapes. Then, the tapes are taken to an off-site location and stored. (Hopefully at a minimum you are at least doing this. If not, you are putting your entire organization at risk.) Every organization that does this has its own processes put in place and a schedule for backups that meet their business needs, but the overall goal is the same: making sure you are prepared for all issues that may occur.
Today, a new and improved way of data backup is becoming the norm: Remote Backups. It allows an organization to schedule their backups to take place just like they would with a tape backup system; however, the major difference is that there is no tape. This means there is no tape to be shipped off site or shipped back after the new tape is sent out. Instead, the data is backed up directly to a server in a remote location.
Remote backups offer many of the same features as tape backups, at a fraction of the cost, because tape drives and tapes no longer have to be purchased or setup. Plus you don’t have to worry if your off-site storage is safe enough. Most online backup solutions offer backups in different locations. So if you have a backup on the east coast and a backup on the west – the likelihood of anything happening to your data is slim to none. In the situation of a massive flood, those who take their tapes off-site a mile or so away, still wind up being ruined.
In addition to added security and the cost benefits, if your company still has internet access after the server goes down or the information is lost, the data can be instantly downloaded from the remote site and loaded on to that server or another backup server. In a case where there is an internet outage, just like you would with a tape, the information can be burned on to a DVD and shipped overnight to your local site. This is a huge bonus considering that with the tapes, you would have to wait for them to be mailed no matter what the circumstance. Having the ability to possibly decrease your downtime by a full day or more is extremely significant and could possibly be the factor that allows you to stay open.
If you aren’t backing up you should. If you haven’t thought about remote backup, you might want to look into it for the added security, cost savings, and its reliability.…

3D Television – Are We Ready to Upgrade?

Hot on the heels of the high definition revolution, television manufacturers are introducing the next game changer, 3D television. So sure is the industry of our willingness to upgrade, that they have already flooded the market with a wide array of competing 3D LCD televisions. Not only is the market prepped for early adopters, newer technology, such as 2D to 3D conversion technology and sets that do not require glasses, looms on the horizon. However, one has to wonder if the industry is correct. Is the average person ready to upgrade to 3D television so soon?
The television manufacturing industry seems certain but no one else seems so sure. While the manufacturers have managed to generate a lot of publicity surrounding 3D television, one has to consider the potential benefit for the common TV viewer. The big players, such as LG, Panasonic, Samsung, Sony, and Toshiba, invested a lot of money at the 2010 Consumer Electronics Show convincing us that this technology would change the way we experienced television. We bought in to it for a while. They had flashy tech on hand and statistics that indicated that at least 25% of consumers planned to purchase a 3D television within the next three years.
However, once the newness wore off, and it wore off quickly, we began to wonder about some of the issues and began to notice that the industry may have overstated demand. Did excitement over James Cameron’s film Avatar exaggerate the hype? It certainly seems that way in retrospect. Looking at Avatar on a top-of-the-line 3D television is a remarkable sight. However, when you broaden the experience one cannot help but think that the 3D experience is of limited usefulness in a home environment.
Toshiba wants the consumer to believe that their new 2D to 3D conversion technology will change their life. However, can most people imagine watching reruns of Seinfeld and thinking, “Wow, this is so much better in 3D?” Industry marketing has focused on how much and how fast 3D content will be available. No one seems to be asking how many 3D content consumers actually want. We suspect that is quite a bit less than the industry initially believed.
There are other issues, such as practicality, that will affect demand. As television viewers, we are by nature lazy, at least at those moments when we want to watch television. There is a stereotype that men would rather stare at an infomercial than get up and fetch the remote. There are truths in stereotypes. Are people going to want to wear these contraptions for long periods? Are they going to want to manage sets of glasses? These shutter glasses need maintenance through charging, cleaning, and safekeeping. Moreover, there are large expenses involved. How many do you need? The average family needs four but will likely want additional units for those times when company is over.
Shutter glass-less technology will erase many of these issues but it is going to carry a premium that will exclude most potential 3D television buyers. There are also pricing issues that extend beyond the cutting edge sets. These are difficult economic times and many families have just recently spent a great deal of money on HD sets that they hoped would last five to ten years. The industry can try to convince us otherwise but we have difficulty believing that the core of potential customers will support this new technology anytime soon or will they?…

Benefits of Interactive Voice Response System

You must have come across the automated calls of people trying to market their products. In the conventional times, the trend of telemarketing indulged a person who used to dial the number and call you personally. However, the new and much improved interactive voice response system is more efficient and within few seconds the pre-recorded marketing pitch is sent to numerous numbers with the usage of robust network system. IVRS also known as Interactive Voice Response System, has contributed significantly in the field of advertisement and marketing.
In fact, the IVRS technology has transcended to several domains like healthcare, banking, education, real estate, and politics. IVRS solves the problem of telemarketing resourcing cost. For example, in the earlier times a caller used to call prospective client(s) manually and considering that one call took 5 minutes then the resource could inform barely 100 clients a day. However, the data of prospective clients is filtered through the computer and then the pre-recorded phone call is propagated to thousands at the same instant. Thus, with the IVRS the relevant information is propagated to thousands of prospective customers and hence the associated advantages of IVRS can easily be drawn.
IVRS not only contributes in the marketing or promotional campaign but the technology is also used to communicate the message in case of any disaster. This way, people get informed about the directives and hence it helps lives and loss of property too. The clinical interactive voice response system is also an innovative technology system that has helped hospitals and pharmaceutical companies to effectively market themselves. The IVRS technology is used through autodialers which work on autodialer alerts and notifications, autodialer messages (SMS), IVR based phone calls, and inbound calls.
The complete result of IVRS is an integrated effect of the autodialers, IVR and computer technology and the technology of computer telephony integration (CTI). The autodialers in the IVRS involves three services that include incoming calls, outgoing calls and bulk messages. So, start sending automated calls to increase the number of customers and sales. Give your business the much required effective marketing support of Interactive Voice Response System.…
