This is the second time the spectrum sale has been pushed back. It was originally scheduled on May 20, and was initially deferred to June 6, in the wake of the general elections. Now, mock auctions will be conducted on June 13 and 14, the DoT said in its official notification amending the auction rules. This time round, 5G airwaves in eight bands — the 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 3.3 GHz and 26 GHz bands — worth over Rs 96,000 crore at base prices, will be on sale.
