what is E - H/H+ - LTE - VoLTE - 5G - Network Generations

 You Know? what is E,H/H+,LTE , LTE+,VoLTE. We all see these symbols daily on our mobile phones.

E:-

The mobile signal letter E stands for EDGE (Improved Data Rates for GSM Evolution). This technology is somewhere between 2G and 3G technology It's the second slowest mobile network, and it's usually the last network to connect to a modern smartphone. When your phone uses better data rates for GSM Evolution you will see the E mark, also known as enhanced GPRS. It Provides 400 kbps

H/H+:-

Your device is using high-speed packet access(HSPA+) when you see the H mark. You can browse the internet on this network and stream audio/video without any problems, At 7 Mbps speeds, texts and calls are generally fine

H+ can usually provide really decent speeds of up to an impressive 168 Mbps.

LTE:-

LTE (long-term evolution) is a single cellular connection. It is already being promoted as 4G  "fourth generation" due to marketing reasons. LTE  is actually 3.9G  mobile network technology with a maximum data speed of 300 Mbps. The average speed is 15-20 Mbps.

 It may or may not support voice calls and data at a time. When you "make a voice call .. Data services will be turned off automatically and your calls will be connected via 3G".

LTE+ :-

LTE Advanced (LTE +) is a Multiple cell connection. It describes the 4G standard. LTE + is an enhanced LTE version with LTE Advanced and maximum data speeds of 1-3 Gbps. The average speed is 60-80 Mbps. It supports voice calls and data at a time.

VoLTE:-

VoLTE (Voice over Long Term Evolution)is a fourth-generation network. VoLTE was developed after a problem with the LTE telecom operator, which preferred both the Internet and the Voice call.

VoLTE is the only way to provide voice services via LTE and VoLTE must provide HD voice. It is a digital packet voice service delivered via IP over an LTE access network. 

Network Generations:-

Cellular communications networks are known by their numerical generation 1G,2G,3G,4G, and 5G.

1G:-

It was introduced in the US in the early 1980s and was designed specifically for voice communication.

It was the first generation of wireless mobile communication that used analog signals to transmit data.

• speeds up to 2.4 kbps.
• poor voice quality.
• big phone and low battery life.
  
• no security for data.

2G:-

It was launched in 1991 in Finland. It was the first digital cellular network.it used CDMA technologie.2G technologies have replaced similar technology through digital communication by providing services such as text messaging, Image messages, and MMS.

 2.5G:-When GPRS technology was introduced, it launched web browsing and email services.

3G:-

Third-generation mobile systems offer high-speed data transmissions of 144kbps to 2mbps. It used technologies like EVDO, HSPA, and UMT3G. 3G is mostly used with mobile phones and handsets Connect your phone to the Internet or other IP networks to make and download voice and video calls. 

Supports multimedia applications such as 3G full-motion video, video conferencing, and Internet access.

4G:-

Continuing the trend of the new mobile generation, it was introduced in 2011. The fourth generation of mobile communication upgrades existing communication networks and provides users with a comprehensive and secure IP-based solution that provides users with voice, data, and streamed multimedia on an "anytime, anywhere" basis and much more data compared to previous generations.4th generation (4G) cellular networks, namely, LTE / LTE-advanced and WIMAX 802.16m.

5G:-

5G is almost complete wireless communication with no limitations. Somehow people call it the real wireless world. It is highly supportable for the wwww(wireless world wide web).

Describes some disruptive technologies for 5G, including device-centric architectures, millimetre wave, and massive MIMO.

There are three different ways to build a network, depending on the type of assets the wireless carrier owns.

1. Low-band technology: Low-band 5G networks offer a wider coverage area, but are only 20% faster than 4G. The carriers that make up the low-band network for 5G can make the most of their current 4G LTE infrastructure.

2. Mid-band technology: mid-band spectrum technology offers faster speeds and less latency.

3. High-band technology: High-band 5G networks can deliver super-fast speeds, but their signals do not travel well and have difficulty navigating through rough surfaces. At high-speed levels, the millimeter-wave or mmWave technology is used in the 20-100GHz (GHz) range.

5G

how it works:-

The data travels along with the radio component of the electromagnetic spectrum, with frequencies between 3 kHz and 300 GHz (GHz). 1G or first-generation cellular network technology operates on frequency bands between 850MHz (MHz) and 1,900MHz. 2G and 3G ranged from 850MHz to 2,100 MHz and 4G ranged from approximately 600MHz to 2.5GHz.

how 5g affects the human body:-

Frequencies emitted by X-rays, gamma rays, or ultraviolet light (sunlight, UV lamps, etc.) are classified as ionizing radiation, which is as strong as to damage to human cells and DNA. In fact, it has long been known that prolonged exposure to these sources increases the risk of cancer.

Conclusion:-

A generation stands for Mobile Wireless Standards, and it includes values for data capacity, quality, and encryption. This advanced version of mobile wireless standards performs well when compared to its earlier standards.
