Texas Instruments to ship chipsets based on its non-IEEE version of 20+ Mbps 2.4 GHz wireless using PBCC: this development marks the beginning of the end, potentially, for harmonization at higher bit rates in the 2.4 GHz band. The IEEE's 802.11g task group has been closing on approving the OFDM modulation proposed by Intersil to reach 22 Mbps; TI's alternative would be incompatible, though TI claims greater backwards compatibility. The Balkanization may begin, though, as TI ships chipsets, which they anticipate by fourth quarter.
