Despite some hurdles to overcome, Wi-Fi RFID tag shipments will grow at over 100 percent annually through 2010, reports In-Stat.

The technology is attractive because Wi-Fi RFID allows businesses to leverage their existing Wi-Fi investments for asset tracking, the high-tech market research firm says.

“Historically, one of the key weaknesses of this market has been the short battery life of asset tags,” says Daryl Shoolar, In-Stat analyst. “G2 Microsystems, the only tag-specific vendor, has made stride in overcoming this weakness, with multi-year battery life now a reality.”

Recent research by In-Stat found the following:

• AeroScout shipments accounted for the majority of all Wi-Fi RFID tags in 2006.

• 2006 worldwide Wi-Fi RFID tags shipments reached 135,000.

• Key verticals for growth will be healthcare, heavy manufacturing, transportation and logistics.
