USR's announcement means that Texas Instruments—which supplies the wireless chipset for USR's 802.11g line—has joined with the other major manufacturers of 802.11g chipsets in pushing its own flavor of 11g speed-tweaked technology.

USR's announcement said its upcoming firmware and driver updates will boost wireless bandwidth performance from 100 Mbps to 125 Mbps by using packet aggregation and frame bursting mechanisms. This makes TI's technique comparable to Broadcom's Afterburner, which also originally claimed a boost to 125Mbps.

But it seems that some Broadcom customers are reconsidering specific high-Mbps claims for their products. Linksys' recently-introduced "Speed Booster" product packages [related story] prominently display a "Boost Performance up to 35%" logo and have even removed prominent display of the normal 54Mbps 11g speed claim. Buffalo Technology has removed its WHR2G54 125Mbps router—which was supposed to begin shipment in February—from its website entirely, citing development delays.

USR says all its 11g Wireless Turbo products will be shipping with the 125Mbps enhancement by "early June" and that existing owners will be able to upgrade their products via a free download. The upgradability also contrasts with Broadcom's approach. According to Linksys, its "Speed Booster" products are based on new chipsets and its existing Broadcom-based 11g products can't be upgraded.
