Entering the Wireless Era

Wednesday, January 16th, 2013

The enchantment of technology is so amazing that it has taken over the world and has brought us to the Era of the Wireless. If we look at the evolution of wireless technology, it began with Alexander Graham Bell inventing the telephone. Soon later the radio was invented, followed by cell phones and soon the introduction of Wi-Fi and Bluetooth. Things simply became much easier. It’s time that we get rid of all those wires and welcome the wireless era, but before that lets take a brief overview into the evolution of wireless technology.
Wireless Network
Theory of Electromagnetic Radiation and the Evolution of Wireless Technology:
Clark Maxwell was the first to explain in 1857, the mathematical behavior of electromagnetic waves. It was in 1901 that G. Marconi invented the transatlantic radio transmission that worked on the fundamentals of electromagnetic waves. Nonetheless, the transmissions of these systems were very small. It was not until the 19th century that these electromagnetic waves were discovered as a form of communication.

First generation
The first system to be developed after the discovery of these electromagnetic waves was the cell phone (car phone) during the 1940’s-50’s in Europe. However, these single cell systems were limited by their mobility, limited service, poor speech quality and low capacity. It was in the 1970’s that the first generation of cell phones were developed, which gave the cell phone industry its quantum leap in the communication sector. The 1G system based cell phones were much lighter, more sophisticated and above all smaller than their previous counterparts. But, there was still a problem; these 1G system cell phones could only transfer information in analogue voices.

Second generation
It was then in the 1990’s that second generation of cell phones were developed that worked on the global system for mobile communications (GSM). 2G worked on the GSM fundamental that provides limited and voice data services, by using digital modulation that improves voice quality. The 2G cell phones were developed on the system and were driven by the constant need to improve transmission quality, coverage and system capacity. Advances in the semi-conductor brought more improvements from digital transmission to mobile communications. Though speech transmissions dominate the airways, the demand for short messages, data transmission and fax are rapidly growing.

Third generation
GSM has the ability to support over 250 million of the world’s 450 million cellular subscribers that provides international roaming. With high mobility, cellular connectivity speed soon became an issue dropping to 144kbps. This is when the third generation system was introduced. 3G cellular systems known as the IMT-2000 or the Universal Mobile Telecommunications System (UMTS) provide a higher data rates and allow more internet application usage.

Fourth Generation
Wireless InternetWith our constant need to improve, 3G wireless systems were even not enough. Thus, the introduction of a more powerful communication system, the 4G system, was developed in 2006 and was made available by 2010. The 4G cellular communication has a transmission rate of up to 20 Mbps which is higher than the 3G systems. The 4G system was developed on these following fundamentals like 50 times more speed than 3G and available bandwidth of 10Mbps.

Wi-Fi
This is the marketing name given to IEEE standard 802.11 systems. Wi-Fi is standard for both physical and data links concerning wireless transmission. A Wi-Fi system produces a radio frequency band of around 3 Gigahertz and it is setup with various channels within a band. These channels overlap each other allowing at least 3 channels to be used simultaneously.

Since the evolution of wireless technology, the ones that profited most by these advancements were the cellular service companies. Virgin MobileCellular giants such as Virgin Mobiles and T-Mobile provided service to various customers based on these cellular advancements. They began to provide benefits for their clients such as faster downloading. This allowed video chats to be made from anywhere through cell phones and tablets, improving smart phone capabilities as well as improved international roaming.

With prepaid phones being on the rise, many phone service providers would put a time limit on your minutes, especially if you don’t use them. This form of planning should be avoided and is why cellular service providers such as T-Mobile and Virgin Mobiles are amongst the most popular cellular service providers since their minutes don’t expire, if you work according to their setup.

T-MobileThey don’t stick you with any annual contracts and provide you with 4G services which are catered to your needs. Another great option provided by them is pay as you go. This setup has allowed them to provide top notch cellular services across the globe.

In the wireless era, you’re not just limited to cell phones. You have wireless speakers, keyboards, mouse and even wireless printers. You never know what might come up next. And while new technology is always cool and exciting; it can also be heavy on your pockets. You can check out eWirelessCoupons.com for discount coupons on most wireless retailers.
