Recently, the Department of Telecommunications (DoT) has sought inputs from telecom companies and other industry experts on the sale and use of radio frequency spectrum over the next 10 years, including the 5G (Fifth Generation) bands.

Key Points

  • Features of 5G Technology:
    • Millimeter wave spectrum: The 5G networks will operate in the millimeter wave spectrum (30-300 GHz) which have the advantage of sending large amounts of data at very high speeds because the frequency is so high, it experiences little interference from surrounding signals.
    • Upgraded LTE: 5G is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • Internet speed: In the high-band spectrum of 5G, internet speeds have been tested to be as high as 20 Gbps (gigabits per second) as compared to the maximum internet data speed in 4G recorded at 1 Gbps.
      • 5G network speeds should have a peak data rate of 20 Gb/s for the downlink and 10 Gb/s for the uplink.
    • Bands in 5G: 5G mainly work in 3 bands, namely low, mid and high frequency spectrum — all of which have their own uses as well as limitations.
      • Low band spectrum: It has shown great promise in terms of coverage and speed of internet and data exchange however the maximum speed is limited to 100 Mbps (Megabits per second).
      • Mid-band spectrum: It offers higher speeds compared to the low band, but has limitations in terms of coverage area and penetration of signals.
      • High-band spectrum: It has the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
