Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet, many consumers consider that the price cellular network operators charge for it is too high. In this paper, the authors explain that there exist alternatives to cellular networks for the provision of SMS. In particular, they present the Self-Organizing Wireless messaging nEtwoRk (SOWER), an all-wireless network operable in cities. In SOWER, each user installs a wireless, power-plugged, device at home and communicates by means of a mobile device. Based on the experimental measurements of IEEE 802.11 equipped devices, they show the feasibility of the concept in various urban scenarios.
