The Inquirer reports PCI Express and USB will soon start showing up in cell phones. This will enable handsets to use well-known standards from the computer industry, hopefully leading to shorter development times and lower costs.
The Peripheral Component Interconnect Special Interest Group (PCI-SIG) is also planning a Next Generation Form Factor (NGFF) that will be smaller than the existing mini-PCI cards that are available in both half and full sizes. This specification is presently at revision level 0.7 and probably a year or so from completion.
The USB-IF is also forging ahead with introduction in mobile phones. According to Jeff Ravencraft, president of the USB-IF, the USB standard will be used for inter-chip communication.
