4G Technologies and Telemedicine Essay

Less than a decade ago, the telecom operators in the U.S., Western Europe, and Japan were upgrading their existing networks to high-speed 3G technologies. Now the world telecommunications industry is about the switching to the next-generation super-fast 4G technologies.

Telstra than discovered 3G and 4G Internet now they both do the same thing, which is for you to connect to the Internet but 4g, was created to make Internet streaming faster.

4G or fourth generation technology is a mobile communication standard intended to replace 3G allowing wireless internet access at much higher speeds!

The first generation of mobile communications started with the Advanced Mobile Phone Systems (AMPS), which was an analogue system regarded as 1G. Then came GSM and CDMA-one (pretty much regarded as 2G) and then to UMTS and EV-DO, which are 3G technologies. The latest technologies for 4G are LTE (from the 3GPP group) and 802.16m (from the IEEE). In the case of 802.16m, the candidate for 4G is also known as Wireless MAN Advanced, or WiMAX2. LTE progresses through versions known as releases. The latest release that qualifies as being 4G is

During the 20th century, the key technology was information gathering, processing and distribution. This total technology will depend based on the network systems. Which are nothing but grouping of systems that should be controlled by a server. In business and home applications, mobile users and in all social issues the networks are used . To enhance the benefits of these networks, we are introducing 3G systems. The aim of the 3G security architecture is to improve on the security of 2G systems.3G systems have additional standards like EDGE and CDMA rather than older systems. It has a high quality voice and video services but has limited in coverage area. Now introducing the 4G technologies to full fill the limitations of 3G.

5G (5th generation wireless systems or 5th generation mobile networks) denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G itself is a revolution, with speeds beyond what the current 4G has to offer.

A company can improve its revenue and profits through high speed internet connection available with the help of 4G 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. 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

A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passenger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells. Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted.

The world today is so deeply evolved with the use of technology a resource. The future of mobile data system has always been a mystery and a question of excitement due to the fact of how different is it going to be from the present generation of mobile data. Mobile data system has been a developing area over the years starting from analogue phone calls to All Internet protocol and communication protocol. The idea for a better and for a more successful next generation of mobile data was inspired from the previous generation. Also, with the development of various apps in smartphones and tablets with data services, it made a plus point in the people’s electricity usage or having to turn of electronic appliances. The term “5G” is the next big

3G is the third generation of wireless technologies. It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.

Long Term Evolution (LTE) is 4G wireless communications standard radio platform technologies that allow operators to achieve higher peak throughputs than HSPA+ in higher spectrum bandwidth. LTE was developed by the 3rd Generation Partnership Project (3GPP), and this began in 2004, with an official LTE work item started in 2006 and a completed 3GPP Release 8 specification in March 2009. Initial deployments of LTE began in late 2009, and it is part of the GSM evolutionary path for mobile broadband, following EDGE, UMTS, HSPA (HSDPA and HSUPA combined) and HSPA Evolution (HSPA+). Although HSPA and its evolution are strongly positioned to be the dominant mobile data technology for the next decade, the 3GPP family of standards must evolve toward the future. HSPA+ will provide the stepping-stone to LTE for many operators.

With the rapid development of communication networks, it is expected that fourth generation mobile systems will be launched within decades. Fourth generation (4G)

The 2.5G it is basically an enhancement of the two major 2G technologies to provide increased

4g has seen different advancements and various innovation upgrades, from beginning with original to advance to Second era amid which we first saw show of exchange pace surpassing 64 kbps, 2g was advanced by Third Generation of portable correspondence with its exchange velocities of 2 mbps. As time advanced we saw presentation of fourth
