Many wireless business failures during the past few years were victims of a poorly written business plan, not the leading technology and system design. Early attempts by AT&T Fixed Wireless, Sprint, Winstar, Teligent and others to capture last-mile broadband internet access had disastrous results. In late 2001, they pulled the plug on their failed alternative to digital subscriber line and cable Internet services.AT&T took a $1.3 billion hit after receiving only $16 million for their remaining assets. An economic domino demolition caught many small and large businesses by surprise. Previously ordered equipment and shelters sat on company books for over a year and businesses were forced to lay off support employees assigned to the ambitious build out. It was not the RF or topographical elements that shut down early attempts. The line-of-sight requirements from the base station to the subscriber's home were known during developmental stages. They failed, however, to identify the true cost of installing and servicing the pizza box-sized antennas on the exterior of the home or office. Multiple service calls by a skilled technician were required to relocate and complete the installation. Second generation wireless broadband systems, if designed with the business case in mind, have a greater opportunity for success through significantly reduced operating costs.
