Abstract
• Propose modification to the co-existence matrix
• Suggest an additional element of “network operation/ownership” to be considered as part of a use case
• Provide detailed analysis of 2 use cases– Campus (i.e. college campus, suburban mall, etc.)
– Large apartment building

Observations from the Matrix
• It would appear that in general different technologies cannot co-exist except through sufficient geographical separation
– UWB is an exception
• However, this depends on an underlying assumption of passive co-existence
• In some cases, the notion of an active coexistence enabler is not unreasonable– For example if a single operator of a heterogeneous network is provided such a device
• Our use-case study needs to address such possibilities– In particular, we should differentiate between co-existence between networks operated by
different entities and co-existence of network operated by the same entity– We examine two scenarios which make illustrate this point

The Campus Use Case
• Key aspects of this Use Case– Presence of macro-coverage
• Cellular providers• Fixed WWAN (Wimax)
– Potentially high density of 100mW devices
• WiFi networks (per store, department, etc.)
• WiFi hot-spots• Femto-cells
– 40 mW devices– Microphones– Presence of a single coordinating
entity• Campus owner• Mall owner• This entity may
– Own and sublease all or part of the network
– Impose constraints and requirements on network operations by individual operators

The Apartment Building Use Case• Key aspects of this Use Case
– Presence of macro-coverage• Cellular providers• Fixed WWAN (Wimax)
– Potentially high density of 100mW devices
• WiFi networks (per store, department, etc.)
• WiFi hot-spots• Femto-cells
– 40 mW devices– Microphones– Each apartment potentially an
independent network• May use different
broadband/cellular/femto-cell providers
• No ability to coordinate WiFi usage (except maybe direct human goodwill)

Conclusions
• Made comments to the matrix
• Presented 2 use cases (see our text for more detail)
• Propose that the notion of a “operating entity” is an important factor in considering a use case.
