Introduction to 4G LTE training: 

4G LTE training at Global Online trainings – LTE stands for Long Term Evolution and it is the technology behind today’s 4G cellular networks. The telephone you’ve got today almost certainly uses LTE to attach to the cellular network. LTE provides high-speed mobile broad band data digital cellular telephone service supports multimedia video and public safety functions like secure database access, mobile CAD and RMS and non-mission-critical push-to-talk.You are using LTE today, all major smart phones and cellular devices manufactured since 2011. Support LTE and use LTE for data access. It is used by virtually all carriers in the entire world for the current generation of cellular communications. Global online trainings is best in providing 4G LTE fundamentals training by industry experts at flexible timings.

Overview of LTE training:

  • LTE is also the technology endorsed by public safety for the nationwide public safety broadband network which will be built by first net. This is true in the United States and abroad. LTE is that the technology that each one public safety agencies across the world shall use in their future mission-critical public safety broadband networks and even better by adopting LTE as its next wireless technology standard. Public safety will always keep step with current technology.
  • LTE just represents the current version of these standards. This means that by adopting LTE for firstnet and the nationwide public safety broadband network public safety is already prepared for 4G and 5G in the future. So what does an LTE network appear as if within the real world? An LTE network has four major components or subsystems. First is the core network which is the brains of the network it consists of servers and gateways that control access quality of service billing and network policies and the core provides access to the internet and multimedia services like telephone calls.
  • Second is the radio access network, the easy way to think of this is that the radio access network are the sites that you see the cell towers. Backhaul network connects the radio access network to the core network, the Backhaul network represents the roadways where the data gets from you and your device back to the core network.
  • So you can access the network make telephone calls and access other network services. Last but not least is the user equipment which consists of cell phones mobile routers and other devices used by individuals your cell phone would be considered user equipment. The user equipment connects directly to the radio access network. This is the subsystem you are probably most familiar with because your cell phone is a piece of user equipment.
Components of 4G LTE fundamentals training:
  • These beach front frequencies are very valuable and are extremely similar to the frequencies powering the lightning fast commercial cellular networks today including Verizon and AT&T. As you’ll see however the frequencies for firstnet and therefore the nationwide public safety broadband network are completely break away the frequencies for major carrier networks.
  • This means that during a major disaster when commercial networks get overloaded and failed first responders will have their own frequencies for mission-critical communications. For example have you ever ever been to an enormous event where there are tons of individuals and albeit you’ve got good coverage and a robust signal. You can’t get through to the network that’s because there’s numerous people using it. With the nationwide public safety broadband network. This won’t happen to first responders because they will be on their own frequencies.
  • The second primary benefit of LTE for public safety is its high speed, this is true both for a commercial carrier who uses LTE as well as for firstnet on the nationwide Public Safety broadband network. You can see that in the North east and south sectors each user gets about half of the bandwidth or 20 megabits while the user who has the NorthWest sector.
  • In the second example you can see that there are more users in the south in Northwest sectors, south sector because there are 3 users each gets about 13 megabits per second or about one third of 40megabits each. In this last example we see that we’ve four users within the northeast sector because there’s numerous of them each user only gets about 10 megabits per second or one quarter of the entire 40 megabits for that sector.
  • You can see still each user within the south sector gets 13 megabits and every user within the Northwest sector gets 20 megabits per second. This is really an important concept in LTE each sector supports about 40 megabits per second of data as you get more and more users in that sector. That sector is going to be much slower. This is why when you are at a large event you won’t get very fast Internet service from your cell phone because even though you have a good signal there is so many people sharing the same antenna that there just isn’t enough data to go around.
  • This example shows they are each going to get 10 megabits per second for their traffic and the second example we see that the user on the left-hand side has a higher priority than everyone else.
Features of 4G LTE training:                                                                                                                                      4G LTE Training
  • So everyone else gets a lower speed at 8 megabits per second while our one user at priority 2 gets twice as much throughput at 16 megabits per second. This is an important concept in public safety because going into the future public safety agencies will be able to determine and what deserves higher priority and should get more data access and other user applications.
  • In this last example we are showing pre-emption, the user not only has higher priority than everyone else but is making an emergency call. You can see here that the second user is assigned priority 9. The first user is a priority 1. In this case the network would decide that the priority 9 user can wait and would allow the emergency call to completely pre-empt that users traffic.
  • Last and certainly not least is the self-organising network or SON while there are many features  that go into  the self-organizing network. In this example we see that the site on the North has lost an antenna and the sector on the southwest for the Northsite is no longer on the air.
  • In a traditional network such as a trunked radio system, this area would simply have an outage, you would have no service there. But LTE networks can be set up to accommodate for those outages dynamically and on the fly in this case the site on the South has increased the power for its North Sector to cover the outage area temporarily. This allows the users in that sector to still have service. Now that sector is larger so there are going to be more users sharing that same sector and those users will all have lower throughput but it’s better than having a complete dead spot.
  • Once the southwest sector on the North site has been repaired and is back in service. The network can automatically go back to its original state and power down the sector at the South site that it increased its power to cover the outage area in Comm ip telephony training. This all happens automatically in LTE with the self-organizing network feature.
  • It’s endorsed by Public Safety and virtually every carrier worldwide for cellular communications. LTE has many features that are attractive to Public safety including exclusive spectrum high-speed priority and pre-emption and the self-organising network. And we know that by adopting LTE as the technology for firstnet and the nationwide Public Safety broadband network, Public safety is already future proved for 4g, 5g and beyond.

Conclusion of 4G fundamentals training:

What’s the bottom line? LTE has many features and capabilities but there are four aspects to the LTE based nationwide public safety broadband network. We will really be very beneficial to Public safety. These four features are exclusive spectrum, high-speed data priority and pre-emption and the self-organizing network or SON. Frequencies allocated to and the nationwide public safety broadband network is in the 700 MH range. These are the same frequencies that were previously used for broadcast television before the digital TV transition a few years ago.
