The smartphone-toting, social-networking crowds often overwhelm cellular networks in the area, creating a market that BBH Labs hoped to serve with the "Homeless Hotspots" project, which it called a "charitable experiment".
Opportunistic networking is viewed as a promising complement to cellular networks in different respects, e.g., for offloading delay-tolerant traffic load from them [8].
Forecasts vary, but 3G is expected to be up and running on a number of cellular networks in this country by 2003.

Range Networks is also working on the challenge of creating cellular networks in underdeveloped areas.
One-way relaying is shown to provide modest gains over single-hop cellular networks in some regimes.
Moreover, small cells can provide a fast, flexible, and cost-efficient solution for existing cellular networks in [9].
Fast growth of wireless cellular networks in the past decades raises a critical problem of energy consumed by network equipment.
To this end, we assume that D2D users reuse the downlink resources of cellular networks in an underlay fashion.
We address the problem of analyzing the performances of interference-limited cellular networks in large-scale shadowing environments.
