Query: H-AP Deployment for Joint Wireless Information and Energy Transfer in
  Smart Cities   With the wireless communication being more various in the future, it's
becoming challenging to prolong the lifetime of many battery powered devices,
since frequently replacing their batteries is a cumbersome job. An hybrid
access point (H-AP) is capable of simultaneously operating wireless information
transfer (WIT) and wireless energy transfer (WET) by exploiting the radio
frequency (RF) signals. By jointly considering both the mobility of the user
and the popularity of the sites, we focus on the design of the H-AP's
deployment scheme. Specifically, a mobility model of the grid based city
streets is exploited for characterising the users' movements. Based on this
mobility model, the impact of the deployment site's popularity on the WIT and
WET efficiencies is firstly analysed. Then, an H-AP deployment scheme for
striking a balance between the WIT and the WET efficiencies is proposed, which
is regarded as the B-deployment scheme. The simulation results demonstrate that
the B-deployment scheme is more flexible for satisfying diverse requirement of
the WIT and WET efficiencies.
