Explanation:

Recently, Reliance Industries announced that Jio has designed, developed a complete indigenous 5G solution ready for deployment.

• 5G or Fifth Generation is the latest upgrade in the long term evolution (LTE) mobile broadband networks.
• The 5G spectrum is a range of radio frequencies in the sub-6 GHz range and the millimeter-wave frequency range that is 24.25 GHz and above. 
• The speed and latency of which improved with 4G networks.
• The 5G networks will have even faster speeds with low latency between 1-10 milliseconds.
• 5G networks are also designed to multiple-input multiple-output (MIMO) efficient which improves signal throughout for all devices on the network.
• Latency is the time a device takes to communicate with the network, which stands at an average of up to 50 milliseconds for 4G networks across the world.  Hence statement 2nd is incorrect.
