What happened:
When a user requests
content from the server, the
phone intelligently surveys
nearby peers to check for the
same content. On successful                             ‘Lost’

an ad hoc P2P connection
was established with this
peer and the content is
transferred to the user. The
transfer is extremely fast
irrespective of the low
coverage zone.

                                 Joe owns a small coffee shop that serves a high end clientele.
           RS                    He notices that his customers are having trouble getting good
                                 WiMAX service, so he buys and installs a small, inexpensive
                                 relay station near an exterior window that improves coverage
      BS              MS         throughout his shop. Now his customers happily use their
                                 WiMAX devices and stay longer, sipping coffee.



What happened:
A low cost customer premise relay
station (RS) is placed in a location
in which it receives a sufficient
signal to/from the WiMAX base
station (BS). The customer premise
RS then provides indoor coverage to
mobile stations (MS) within the
coffee shop with no additional
infrastructure, site planning or
network management costs to the
infrastructure provider.
