Small-to-medium enterprises (SME) are likely to be attracted by BT's latest business broadband offer.
Firms signing up to BT Total Business Broadband will have the chance to set up their own public Wi-Fi hotspot.
Businesses will have the option of charging visitors for using the service on their premises, but are also able to operate the network free-of-charge.
"Offering Wi-Fi adds value and is good customer service," Bill Murphy, managing director of BT Business, commented.
"It can also allow businesses to make incremental revenue. The service is helping our customers stay online and keep productive during these times."
BT Openzone vouchers sold by firms with the hotspots can also be used in over 120,000 other locations across the UK, the telecoms giant pointed out.
