3		- Widespread deployment of private home \wifi{} access points (APs) can
4		- result in uncoordinated and overlapping wireless networks that compete with
5		- each other for limited bandwidth. We expect this suboptimal arrangement to
6		- only get worse, particularly in the dense urban environments that house
7		- an increasing fraction of the world's population. Broadband penetration and
8		- the demand for high-speed \wifi{} throughout the home will lead to more
9		- private APs, which will generate more interference for neighboring
10		- networks, resulting in even more private APs and additional interference,
11		- and so on.

13		- In this paper we investigate whether we can prevent this vicious cycle by
14		- using \textit{reciprocal \wifi{} sharing} to make better use of existing
15		- private home APs. We define reciprocal \wifi{} sharing as cases where two
16		- users both improve their network performance by connecting to each other's
17		- overlapping private \wifi{} networks. Compared to previous approaches that
18		- attempted to use private APs to create large-scale open-access \wifi{}
19		- networks, reciprocal \wifi{} sharing relationships more closely mirror
20		- existing human relationships and can be maintained without elaborate
21		- reputation mechanisms.
22		-
23		- To evaluate the potential for reciprocal \wifi{} sharing, we analyze 21~M
24		- \wifi{} scans collected from 254~smartphones over 5~months. Our results
25		- show that even in a sparsely-populated suburban area, reciprocal \wifi{}
26		- sharing can be beneficial. And surprisingly, we detected several reciprocal
27		- \wifi{} sharing opportunities even within our tiny user sample. Motivated
28		- by these results, we present the design of \wisefi{}, a system enabling
29		- reciprocal \wifi{} sharing.
