5G Wireless Training Course: To understand 5G, it’s helpful to understand what came before it.
Broadly, the first generation of mobile technology, 1G, was about voice. The ability to use a phone in a car took root here.
G refers to the first generation of wireless cellular technology (mobile telecommunications). These are the analog telecommunications standards that were introduced in the 1980s and continued until being replaced by 2G digital telecommunications.
The main difference between the two mobile cellular systems (1G and 2G), is that the radio signals used by 1G networks were analog, while 2G networks were digital.
Although both systems used digital signaling to connect the radio towers to the rest of the telephone system, the voice itself during a call was encoded to digital signals in 2G whereas 1G was only modulated to higher frequency, typically 150 MHz and up.
The move to 3G provided the essential network speeds for smartphones. It was an upgrade for 2G and 2.5G GPRS networks, for faster internet speed. This was based on a set of standards used for mobile devices and mobile telecommunications use services and networks that complied with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union.
3G found application in wireless voice telephony, mobile Internet access, fixed wireless internet access, video calls and mobile TV.
4G, the predecessor to the 5G wireless network, gave rise to many of the connected devices and services that we rely on and enjoy today because of its considerable increase in internet speeds. But 4G, despite being fast, was stuck in the low-band spectrum, a radio frequency area that quickly became overcrowded given 4G’s popularity and due to 4G having to share this spectrum with TV and radio signals.
The other main issue for 4G is that it didn’t have the architecture behind it to enable a whole slew of new technological advances such as Internet of Things (IoT) mass connectivity, smart cities, smart grids, autonomous cars and remote healthcare monitoring and surgery.
Enter 5G broadband. A discussion around 5G technology is really a discussion around delivering life-changing technologies through next-generation networks.
In other words, mobile broadband is in transition as 5G begins rollout in selected cities in the U.S.
The big jump to 5G cellular networks represents a technological evolution that while the public perceives 5G in terms of improved cellphone service (high speed, low-latency), engineers and all other personnel touched by the broadband industry understand that much more is going on.
5G infrastructure is such a radical departure from past mobile broadband technologies that a whole new set of enablers are involved including NFV, SDN, new frequency spectrum, MIMO and small cell, lower power base stations.
5G also promises to deliver a wide range of new services, applications, devices and enhanced mobile experience such as Enhanced Mobile Broadband (eMBB), Ultra reliable and Low-latency Communications (uRLLC), and Massive Machine Type Communications (mMTC).
5G will meet the demands for an increasingly digital lifestyle, and focuses on services that have high requirements for bandwidth, such as high definition (HD) videos, virtual reality (VR), and augmented reality (AR), digital industry and latency-sensitive services.
Of course, there is so much more to learn about 5G. That’s why Tonex offers 5G Wireless Training / 5G Technical Fundamentals, a 3-day course that covers the most dominant 5G technologies and architectures.
