WiMax network plan dropped

Sprint Nextel Corp. and Clearwire Corp. said Friday that they have scrapped plans to build a high-speed wireless network together after the ouster of Sprint Chief Executive Gary Forsee. The network would use a technology called WiMax, which will allow devices such as mobile phones and laptops to access the Internet across entire cities, instead of limiting them to smaller areas served by wireless fidelity, or Wi-Fi, networks.
