Transmission voice over 802.11

Abstract

Developing countries are pervaded with scarcely populated rural areas. Under those conditions, providing broadband services with an efficient internet access at reasonable costs becomes a difficult endeavor. Thus, the answer lies on finding simple alternatives but different from those implemented in more developed countries. Some solutions applied in these cases involve the use of long range wireless technologies, such as: microwave, 802.11, WiMax, CDMA450, among others. Some of the features fostering these technologies include speed, simple installation, use of frequencies which do not require previous authorization, and, furthermore, the possibility to override local telecommunications operators. This article argues that 802.11 technologies are appropriate in those areas. It also analyzes their behavior when used over areas involving significant distances, with different requirements from those needed to cover populated cities.
