Peer to peer usage model
What happened:
When a user requests
content from the server, the
phone intelligently surveys
nearby peers to check for the
same content. On successful
discovery of an eligible peer,
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.

Direct Link usage model
What happened:
In both cases the WiMAX
devices use peer
discovery to determine
local proximity of other
devices. Channel
propagation loss,
number of hops and
environment type is used
to estimate distance
between devices.
Sample Scenario #1:
Mary uses her and her
12 year old daughter’s
WiMAX devices to
ensure that they don’t
become separated by a
greater distance than
she is comfortable with
at the mall.
Sample Scenario#2:
Sam and his friends use
their WiMAX devices to
notify them that they
are in the same general
area so that they can
meet.

What happened:
The WiMAX system
allocates p2p
resources between
the RS and MS. The
MS-based RS is so
low cost and low
power consumption
that it is
economically viable
to deploy and
maintain.

Every time an mCoupon is shared the sender gets

in control of the P2P network, it

Joe owns a small coffee shop that serves a high end clientele.
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
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.
