(Image credit: Image Credit: Uverse internet) To build or buy? That is a question that every business considers for nearly everything, from trucks to office spaces. Today, enterprises are increasingly asking the same question about cellular: Should they get service from a mobile operator or become operators themselves? Private cellular networks aren’t a new concept. For example, electric utilities such as Alliander have deployed 3G CDMA in the 450 MHz band, while other utility companies have used 4G LTE in a variety of bands. Availability and reliability are two major reasons why so many utility companies chose to build and operate their own networks.
