Consider these current technologies:

There are many organizations providing products and services that make these technologies work.
And, in turn, they rely in part, on a myriad of established small businesses that provide material, parts and services to support their operations and help out with the challenges presented by these new technologies.
I know this, because I worked in the industry for decades as engineer, and now as business intermediary.

They all rely on Telecommunications to operate

To make them mobile, they all need Wireless Communication

I also know that many small businesses want to grow. One way, and a fast way, is to go through acquisitions. Those that do not grow they may stay small for a long time, or grow somewhat, but eventually they change ownership, if they don’t close otherwise.

If you want to sell your small business confidentially, go here
