Not sure what is all about?
Use 2Greet for voice services and stop wasting resources on 2G/3G coverage
Increase the capacity of your network with the same spectrum resources
You don’t need to invest more money in LTE or 5G spectrum because you can reuse the freed 2G/3G spectrum that you got the license for. 2Greet is the accessible technology for future voice services.
Frequency reuse allows you to increase the number of customers that you can serve within a geographic area using the same amount of radio spectrum you currently have.
