The Truth About 4G Networks

4G digitized networks for cellular phones have come a long way since the old analog phone I owned as a young man. It seems that the technology took off without most people even noticing. I can remember Computer Technician Skills Resume the only feature I had on my phone was call-waiting. Now we have video chat, internet, and different applications that seem we cannot live without-like Pandora, Angry Birds, Twitter, and many more.
The history of the generation networks began in the 1980’s with what we call 1G (First Generation) which operated as analog signals. Shortly after 2G (Second Generation) was introduced which ran on a GSM digital network. Obviously, internet access became very popular over the years, so developers Science Issues 2019 launched 3G (Third Generation) which used more packet switching rather than circuit switching. Consequently, bandwidth became an issue; therefore, forcing the movement into 4G (Fourth Generation). 4G IP-networks enabled users to upload material up to 6 Mbps, much faster than 3G’s 1.4 Mbps.
In order for a device to be considered 4G, the ITU requires 4G technologies to be IP-based, use orthogonal frequency-division multiplexing (OFDM), and the technology needs to support peak download speeds of 100Mbps. Although, the telecommunication protocols 3GPP Long Term Evolution (LTE) and Mobile WiMax do not meet IMT-Advanced (International Mobile Telecommunications Advanced) standards, with maximum downloads of only 56 Mbit/s: IMT-Advanced considers a device to have 4G technology if a high level of improvement in performance and capabilities compared to third generation technology networks exist. Both technologies are in the forefront for IMT-advanced compliances in fact; very soon companies hope to demonstrate real-world download speeds in the 70- to 90-Mbits/s range. Although, most users cannot decipher the difference in increased download speeds over the last year or two, most users have noticed the better quality of voice and video.
4G offers many new features that override all the older generations like data speeds which became important with the evolution of 3G. Despite the hype that preceded 3G’s launch, the industry has only been able to live up to its promises nearly a decade later. 4G tackled features such as multi-hop and Ad Hoc networks, quality of service (Qos), higher speeds, lower cost per bit, VoIP, network conversion, and bandwidth from 5-20 MHz
It is amazing how far off these technologies are in compliance to a genuine 4G network, but companies have found loop holes in the 4G standard in order to advertise these so-called 4G networks in order to boost sales. It was stated that carriers are as eager as ever to sign up subscribers and sell them new plans and devices. It looks to me as if all the major telecommunications carriers such as Sprint, T-Mobile, AT&T, and Verizon have deceived their customers just to be number 1. While doing my research, I came across a statement on one of the provider’s website. At the very bottom in very small letters it read, “Theoretically 21 Mbps upload”. I thought this was interesting because the word theoretical means existing only in theory.
