Mobi™ is capable of receiving video signals over its 802.11 b/g WLAN radio using its own internal router, giving a video signal
range of approximately 50 yards line-of-sight. Mobius supports video in both MPEG4 and Motion JPEG formats. For data communications, a 900 MHz Freewave
radio transmitter/receiver is mounted in the molded housing. Tablet PC and Freewave radio specifications
are attached to the end of this appendix.
