What Is LTE Network?

In telecommunications, Long-Term Evolution(LTE) is a standard for wireless broadbandcommunication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.[1][2] LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is sometimes known as 3.95Gand has been marketed both as "4G LTE" and as "Advanced 4G",[citation needed] but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The requirements were originally set forth by the ITU-R organisation in the IMT Advancedspecification. However, due to marketing pressures and the significant advancements that WiMAX, Evolved High Speed Packet Access, and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies.[3]The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced.[4] To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G"
What is 4G?
4G, short for Fourth Generation, is a specification laid down by the International Telecommunications Union (ITU) in 2008.
Since there was such an enormous gap between the old 3G standard and the new 4G, companies wanted to make sure their customer base knew they were receiving better service than just the same old 3G, so they came up with a workaround. That workaround was LTE, short for Long-Term Evolution. The original idea was that it represented a Long-Term Evolution toward the 4G standard. What clever marketers figured out was that they could present it as something greater than that standard if they simply added 4G before it. Hence, 4G LTE.
How Fast is 4G?
The ITU standard stipulated a minimum specification of 100 Mbps download speed, which, at the time, was extremely hypothetical. In fact, carrier networks today are only just now realizing these aims, many years later.
Therefore, to qualify for true 4G, your carrier network has to be able to download at a minimum of 100 Mbps. Some carriers have dubbed this 4G LTE-A or 5Ge to separate it from 4G LTE.
Do 3G and 5G Phones Work on 4G Networks?
4G networks as of now are the dominant network in America, with most voice, text, and calls being handled over 4G. This isn't projected to change any time soon, with 5G mostly looking to handle data. Thus, 5G phones will continue to use 4G networks for the forseeable future (2030 to 2035 is estimated, but 4G could last even longer).
If you still have a 3G phone, look to upgrade sooner rather than later. Carrier networks have been steadily refarming their networks to 4G standards since the mid 2010s, and are continuing at a rapid pace. Soon, the entire country's voice, text, and data will be handled over 4G and LTE networks, and 3G will be phased out entirely.
How Fast is LTE?
As there is no true standard for LTE, it covers the entire range of minimum download speeds from 3G's 20 Mbps to 4G's 100 Mbps, giving it a massive range of potential speeds.
What is 5G?
5G is the next generation of standards laid out by the ITU, and looks to be following a similar trajectory to what 4G did. Phone manufacturers are just now coming out with 5G compatible phones, but carrier networks are nowhere near the minimum 1 Gbps with 1 millisecond of latency required for the standard. As we said, they are just now approaching 4G specifications!
But because of people's awareness of 5G, companies are trying to upsell their existing networks already, with AT&T calling their 4G network “5Ge” despite it not coming close to 5G standards.
Where you're most likely to see something approaching 5G is in the field of home internet, which can theoretically broadcast 5G signal over the air to your home devices.
How Fast is 5G?
5G looks to revolutionize download speeds and may completely change the way devices stay connected. The true speed of 5G is unclear, as the technology is still somewhat up in the air, but it should be able to download a full-length HD movie in seconds - so, around nearly 1 GBps.
However, as we've mentioned before, 5G will not replace 4G. There are too many benefits to 4G than what we won't go into here, but if you'd like to know more about how the 4G and 5G waveform differ, we recommend this article.
Is 5G Safe?
While there have been some fear mongers out there questioning the safety of 5G technology, it's very unclear as of now. Unlike with 4G, very little real research has been done, but what we can say is: most of the frightening stuff that's been circulating on the internet is fraudulent.
What is the Difference Between 5G and 4G?
The difference between 5G and 4G is more than just a waveform. When it's functional, 5G could revolutionize the way we receive data, and, more broadly, the way machines communicate. Whereas the difference between 4G and 3G has kind of come and gone, 5G will be far more noticeable.
Where 5G might NOT be noticable, however, is in your basic calls and texts. This is because, for the next decade plus, cellular carriers plan to make use of existing 4G networks and slowly integrate 5G.
How is 5g dangerous?
Some 5G conspiracy theorists contend that the new network generates radiofrequency radiation that can damage DNA and lead to cancer; cause oxidative damage that can cause premature aging; disrupt cell metabolism; and potentially lead to other diseases through the generation of stress proteins.
Is 5g a weapon?
The 5G network, as a weapon of high-tech capacity, will also become the target for cyber-attacks and war actions carried out with new generation weapons. ... This engagement is of course of the greatest importance, but must be linked to research on the military use of this technology, financed indirectly by ordinary users.
5G won't kill us
It is not strong enough to cause molecular damage. According to experts, because therewill be more 5G cell sites around, it reduces the power levels on each of them. That, in turn, reduces the radiation exposure from each antennae. ... So no, 5G will not kill us.
Is 5g dangerous to birds?
5G Did Not Cause A Mass Bird Die-off
While researchers have speculated that cell frequencies may affect how migratory birdsnavigate, it is not to a harmful degree. So far,5G has not been found to have any directlyharmful impacts on birds.
Does Italy have 5g towers?
In March 2017, Italy launched a 5G trial to implement infrastructures and services in 5 cities: the metropolitan area of Milan, Prato, L'Aquila, Bari and Matera. In September 2017, authorisation was granted for the use of 100 Mhz in the 3.6-3.8 Ghz band for the roll-out of5G in 5 Italian cities.
Which countries have 5g towers?
South Korea, China, and the United States arethe countries that lead the world in building and deploying 5G technology. Telecommunications operators around the world—including AT&T Inc., KT Corp, and China Mobile—have been racing to build the fifth-generation (5G) of wireless technology.
How many countries have banned 5g?
Only a few other countries — Japan, Australia and New Zealand — have barred Huawei 5Gdeals; many world powers remain undecided. American officials cast the race to 5G as a quintessential national security competition, rather than a commercial one.
