Methods, apparatus, and business techniques are disclosed for use in mobile
network communication systems. A mobile unit such as a smart phone is preferably
equipped with a wireless local area network connection and a wireless wide area
network connection. The local area network connection is used to establish a position-dependent
ecommerce network connection with a wireless peripheral supplied by a vendor. The
mobile unit is then temporarily augmented with the added peripheral services supplied
by the negotiated wireless peripheral. Systems and methods allow the mobile unit
to communicate securely with a remote server, even when the negotiated wireless
peripheral is not fully trusted. Also mobile units, wireless user peripherals,
and negotiated wireless peripherals that project a non-area constrained user interface
image on a display surface are taught.
