The research by YouGov and Vodafone UK found that fast mobile connectivity is crucial to public sector workers, but without 4G many are missing out on providing cost effective community services.
The utilisation of 4G technology will allow frontline workers like police officers, district nurses and social workers to further enhance services more cost-effectively.
Of the 1401 senior decision makers surveyed, 30% of respondents cited cost as one of the main reasons for not adopting 4G, while 54% of public sector respondents said 4G is very or fairly important to their organisation.
The research found that the benefits of 4G are not widely understood and cost is still seen as barrier to adoption.
Vodafone UK public sector head Mick Wayman said: "In frontline services such as the police where every second counts, 4G really can make a big difference.
"We are working with public sector organisations to tear down the barriers standing in the way of putting 4G connectivity in the hands of more of Britain’s frontline.
"We are helping organisations to understand how the technology can assist in driving efficiency, delivering better services to citizens and meeting their key priorities."
