The enterprise market (firms with 1,000 or more employees) experienced double-digit growth in mobile data services in 2006, and In-Stat expects double-digit growth to continue over the next five years. While growth in mobile data services is much stronger than that for wireless voice, the bulk of enterprise wireless spending will still go to voice services.
Within the enterprise market, wireless spending growth is expected to be similar across size of business. However, the largest enterprise firms, those with 10,000 or more employees, will account for a majority of the spending in this market. Enterprises account for roughly 44% of all US business wireless spending.
The government vertical accounts for the largest portion of enterprise wireless spending. It is the professional services and healthcare verticals, though, that are expected experience the greatest percentage increases in the coming years, as compared to other vertical industries. This is largely due to the increasing number of employees firms in this vertical will support.
