About 5g Network Technique That Changed Our Life Forever
In telecommunications, 5G is the fifth-generation technology standard for cellular networks, which cellular phone companies offer 2020. Began operating globally in which is the planned successor to the 5G network that provides connectivity to existing cell phones.
All 5G wireless devices in the cell are connected to the Internet and telephone network via radio waves through the local antenna in the cell. The main advantage of the new network is that they will have more bandwidth, delivering higher download speeds, ultimately up to 10 gigabytes per second (Gbit / s). With increasing bandwidth, it is expected that new networks will simply not serve. Cell phones are used as existing cellular networks, but also as a common Internet service provider for laptops and desktop computers, competing with existing ISPs such as cable Internet and also making possible new applications in the Internet of Things (IoT) and machine-to-machine areas. Current 5G cell phones will not be able to use the new networks, which require new 5G enabled wireless devices.
Increased speeds can be achieved in part by using higher frequency radio waves than current cellular networks. Whereas high-frequency radio waves have a lower range than the frequencies used by previous cell phone towers, smaller cells are required. So, to ensure comprehensive service, the 5G network operates three frequency bands, low, medium, and high. A 5G network is made up of networks of more than 3 types of cells, each requiring different antennas, each giving a different trade of download and velocity distance and service area. 5G cell phones and wireless devices will connect to the network through the highest speed antennas within their range of location:
How does 5G work?
Low band 5G uses the same frequency range as current 4G cellphones, 600-700 MHz, with download speeds 4G: higher 30-250 megabytes per second (Mbit / s). The range and coverage area of low band cell towers will be similar to the current 4G towers. Mid-band 5G 2.-3--3.7 uses microwaves of GHz, currently providing speeds of 100-0000 Mbit / s, serving several miles in radius with each cell tower. This level of service is the most widely used and should be available in most metros by 2020. Some countries are not implementing a lower band, making it a minimum service level. The high band 5G currently uses frequencies of 25--39 GHz, close to the base of the millimeter-wave band, although may use higher frequencies in the future. It often achieves download speeds of gigabytes per second (Gbit / s) compared to cable internet. However, with millimeter waves (mm-wave or mm) having a more limited range, much smaller cells are required. They have trouble getting to certain types of walls and windows. Due to their high cost, current plans are to deploy these cells only in dense urban environments and areas where crowds of people gather in playgrounds and conference centers. The above speeds are those that were achieved in actual tests in 2020 and are expected to increase during the rollout
