Markham ON-based Iristel Inc.'s new IP Mobility service represents a solid offering for small and medium sized businesses (SMBs), according to telecom analyst Jon Arnold, giving them the ability to integrate mobility with their existing desktop services while also at the same time getting low-cost wireless long distance. Arnold test drove the service over the past few weeks and describes it as a "very sensible offering for an SMB", although its Wi-Fi functionality creates some limitations.
