In an interview with CRN, Unwired spokesman David Havyatt said the company "is very happy" with its progress in the business WiMAX market since launching in November last year.
The wireless internet products operate on private 3.5GHz spectrum and offer download speeds up to 10Mbps for its contended service, up to 100Mbps for uncontended.
Unwired sells the business products entirely through the channel.
One of its resellers, Star-Tech, recently won a deal with Wesley College at the University of Sydney.
Havyatt said Unwired had been selective in choosing partners that add appropriate value for customers and Unwired.
"We've been very particular targeting the resellers we work with," he said.
"We've signed up 15 to date - and that's close to what we think is the optimal number for the market we're addressing.
"We're pretty close to happy with the channel arrangements we've got in place."
Havyatt said Unwired would still field calls from prospective partners but said they would have to demonstrate the value they can offer.
