Challenge 1: Lack of Flexibility, Performance, and Future Readiness, Resulting in aLimited Ability to Effectively Innovate, Monetize 4G Data, and Monetize Third Partiesby its natur 4G is d sign d to provid high vo um s of mo i data fast. This g n rat sv ry high vo um s of transactions hich r quir strong r a -tim capa i iti s. with 4G r a -tim charging is c ntra to i i ity and innovation.
