History of Fourth Generation (4G) Technology
. The development of 4G (Fourth Generation) technology has been coming over a long line of different generations of technology. Fourth Generation technology is expected to be one of the biggest advancements for mobile technology. It all began with 0G technology. This type of communication system came about in the 1970’s. It was seen among those who were prominent enough to afford it, or used it for their jobs. This was a category of mobile radiotelephones, and incorporated such technologies as Mobile Telephone System (MTS), Advanced Mobile Telephone System (AMTS), Improved Mobile Telephone System (IMTS), Push to Talk (PTT), OLT (Norwegian for Offentlig Landmobil Telefoni, Public Land Mobile Telephony) and MTD (Swedish abbreviation for Mobilelefonisystem D, or Mobile telephony system D) (Introduction to Mobility - Mobility Technologies and Standards). The mobile telephone systems could be found in cars and trucks. 0G technology used analogue frequencies to power its mobile communication systems. It was with this advancement that lead to the next generation of technology.
First Generation technology came about in the 1980’s. 1G technology brought about wireless telephones, a big change from the mobile radiotelephones. They continued to be analogue frequencies but brought a new light of communication into play. The frequencies would distribute out at 150 MHz on average. This was a vast improvement from 0G. When it came to 1G technology there were several different standards, some of these include: NMT (Nordisk MobilTelefoni or Nordiska MobilTelefoni-gruppen, Nordic Mobile Telephone), AMPS (Advanced Mobile Phone System), Hicap, CDPD (Cellular Digital Packet Data), Mobitex and DataTAC (Introduction to Mobility - Mobility Technologies and Standards). The cell phones that were created to use during this time were bulky looking, but were different from its previous land phones that had big transmitters. While 1G had substantial contributions, it would not compare to the new advancements 2G would bring.
At the turn of the 90’s Second Generation technology brought digital over analogue frequencies. This allowed calls to be encrypted with digital signals (Introduction to Mobility - Mobility Technologies and Standards). The changes that came with 2G technology were such a significant and drastic change that it opened the door for the latest technology .The standards that came with 2G technology include GSM (Global System for Mobile Communications), GPRS (General Packet Radio Service), EGPRS (Enhanced data rates GSM evolution),HSCSD (High Speed Circuit Switched Data), and WiMax. It was with GSM that brought the most global communication method. GSM made it possible to have clear coverage and started to implement more than just voice , but data too. There were however, some disadvantages to GSM, it did not have internet and so GPRS and EGPRGS were made (Engineering Projects: 1G, 2G, 3G and 4G telecome technology). Along with new standards came new models of cell phones. They became smaller and more efficient. It was with 2G that analogue said goodbye. Many believed that it would be hard to re-create the success of 2G technology and all it had offer.
Presently 3G is just like 2G but it has a few improvements. Today we know 3G as being able to send and receive text messages, videos, emails , and pictures. Third Generation is also referred to as International Mobile Telecommunications-2000.When it comes to Third Generation, technology and Second Generation technology there are only small differences in the standards. Some of these standards defined by the International Telecommunication Union include UMTS (3GSM) (Universal Mobile Telecommunications System), 3.5 G– HSDPA (High-Speed Downlink Packet Access), and W-CDMA (Wideband Code Division Multiple Access) (Introduction to Mobility - Mobility Technologies and Standards). These standards have fully have evolved from when 0G came around until now. Each standard brought a new set of faster, more efficient way of communicating data and voice. It brought multimedia broadcast and multicast services, which allowed for viewing TV, podcast, movies, webrowsing, while using wifi or free internet services. Not only did it improve communication standards it also improved security among 3G networks. This capability was possible by allowing the network it was trying to connect to, to be verified and made sure it was safe. Third Generation technology has opened the gates for new possibilities for Fourth Generation technology. Fourth Generation technology will prove to be just like Second Generation technology was in the early 1990’s when it hits.
After several generations of technology, 4G has been a long time in the making. This technology is referred as beyond 3G or 4G. Fourth Generation is expected to incorporate 2G and 3G technology while integrating the newest designs. ITU-Advanced will set the standards for the use of 4G technology. According to Technology News 4G will “enable IP-based voice, data, and streaming multimedia at higher speeds- theoretically up to 288 megabits per second for mobile users” (Ortiz). At this rate, 4G concepts and expectations lie with not only mobile phones but other objects as well. One of the focuses is going to be network coverage by being able to cater to the consumer’s needs of wireless networks and faster broadbands for data sending .The main point for consumers is that it will be “Anytime, Anywhere”(4G Technology). Offering services at the consumers fingertips. Some applications that will apply with 4G are:
· Video chat
· Mobile TV
· High Definition
· Fast Downloading
· Wireless broadband access
· Multimedia messaging services
