Broadband provider 3 Ireland has launched a new device which allows users to share their mobile broadband connection.
The firm's Mobile Wi-Fi (MiFi) dongle offers greater flexibility, and can be used by up to three different users at a time.
Mobile broadband can be accessed not just on laptops, but also other devices such as the iPod touch.
Users seeking a pay-monthly tariff can purchase the dongle for 69 (£60), while non-contracted customers face a 139 (£120) charge.
3 Ireland says the dongle is easy to use, commenting: "Just turn on your wireless modem, switch on connection to the 3 network, and select the Wi-Fi function.
"Then choose the Wi-Fi option on whichever device you're using. There's no need to load any software to get online using the wireless modem."
Last week, analyst house CCS Insight claimed that mobile broadband user numbers are set to almost double by 2011.
