Companies in this sector create and own the infrastructure through which data can be sent anywhere in the world through the phone or the Internet. These companies include wireless operators, satellite companies, cable companies and internet service providers.

Now a more decentralised sector, regulation has lowered barriers to entry. Smaller companies in the sector may sell and service communication equipment. Wireless Internet is key to growth in the industry and the expansion of high-speed, fibre networks is expected to be of increasing importance. Meanwhile, a shortage of airwaves has caused consolidation within the industry.
