5G fifth generation wireless technology

All trail carriers in India Govt intend to sell the country’s 5G bandwidth. All the operators will be supplied for checking.

The covered regions are divided into cells, which are serviced by separate antennas. Virtually every major telecommunications service provider in the developed world is deploying antennas or intends to deploy them soon. 

5G is split into mid-band, millimeter waves and low-band. The low frequency is the same as the 4G frequency.

While 4G LTE has focused on delivering mobile broadband services much faster than 3G, 5G is designed to be an integrated, more capable platform that will not only enhance mobile broadband experiences, but Will also support new services such as mission-critical communications and large-scale IoT.

5G will support basically all spectrum types (licensed, shared, unlicensed) and bands (low, middle or high) as well as new ways to interconnect. 

The 5G millimeter wave is the fastest, with an actual speed often of 1-2 gigabits. Frequency is reaching 72 GHz above 24 GHz which is above the lower limit of extremely high frequency. Access is low, so more cells are needed. Millimeter waves have difficulty tracing many walls and windows, so indoor coverage is limited.

5G Mid-band is the most widely deployed over 20 networks. Speeds in the 100 MHz wide band are typically 100–400 megabits. In the laboratory and sometimes in the field, the speed can go above one gigabit.

The frequency deployed ranges from 2.4 GHz to 4.2 GHz.Sprint and China Mobile are using 2.5 GHz, while others are mostly between 3.3 and 4.2 GHz, a range that provides increased accessibility. Many areas can only be covered by upgrading existing towers, which reduces costs.

5G offers the same capabilities as low-band advanced 4G. T-Mobile and AT&T launched low-band services in the first week of December, 2019. T-Mobile CTO Neville Ray has warned that speeds on their 600 MHz 5G may be less than 25 Mbit / s. AT&T will deliver less than 100 Mbit / s in 2019, typically using 850 MHz. Performance will improve, but may not be much higher than good 4G in the same spectrum.

5G networks are digital cell networks, in which the services area are covered by the providers is divided into smaller geographical areas called cells. Analog signals representing sounds and images are digitized into a telephone, converted from analog to digital converter and transmitted as a stream of bits. 

All 5G wireless devices in the cell interact through radio waves with the cell frequency channels provided by the receiver from the pool of frequencies used in other cells and the low-power automated transceivers (transmitters and receivers).

Neo antennas are connected to the telephone network and the Internet by high-bandwidth optical fiber or wireless backhall connections. Like other cell networks, a mobile device crossing from one cell to another “automatically” turns off the new cell.

More than 20 networks are deployed using the middle band spectrum, ranging from 2.4 to 4.2 GHz. Mid-band networks have better accessibility, making the cost closer to the cost of 4G. The Universal Mobile Telecommunications System is designed and modified by 3GPP. The GSM family is a complete change in encoding methods and in technology, although certain GSM sites may be upgraded to a UMTS / W-CDMA variant.

The performance, reach and cost in the same band will be the same as 4G when the 5G system is fully developed and can reach more carrier frequencies.The new networks use 4G to establish connections with cells and where 5G is not available.

5G can support up to 1,000 million devices per square kilometer, while 4G supports only 100,000 devices per square kilometer. 5G can supply a total of 1,000 devices per square kilometre;
