Telstra already has a consumer hotspot using its Ultimate Next G network, but business users might find its limitations on number of devices connected a challenge. The Ultimate Gateway allows up to 16 users to connect via either Wi-Fi or Ethernet, making it potentially appealing for locations such as tradeshows or remote offices.
The gateway costs $399 outright, and is also available bundled with a bunch of Telstra's business 3G plans. Unlike the Wi-Fi only hotspot, there's no battery, so you will need a power outlet. There's also two USB ports to allow you to share access to printers or drives. It's not a solution for individual mobile travellers, but for business teams on the road it's an interesting option.
