pokestake, from the first Mexico release, it looks like broadband was the only thing in the cards for this first install.
"Although the primary use of the Company's first commercially-available network in Mexico is for broadband Internet access, the HotZone 4010 also allows the offering of VoIP telephony through the DECT standard, permitting a typical DECT-enabled cordless phone to have a reach of up to 800 meters from a HotZone 4010 base station, and allows for the fulfillment of WiMAX needs."
