We looked at networks in general; however, in this discussion we’re looking at wireless networks, mostly focusing on mobile networks.  Mobile networks in a global economy can be a challenge for multiple reasons.  First, governments in other countries control the mobile networks.  Second is the technology.  Mobile networks in other countries might not be as good as the mobile networks within the US.  As a global company, how can we deal with this?  With a big push for 5G, which has speeds well over 2Gbps, how does that change the way you do business?  What are some things you need to think about when it comes to doing business globally, using a wireless mobile network? 

note minimum of 250 words.  At least one scholarly source should be used
