Wireless carrier Sprint is rumored to be in talks with discount chain retailer Walmart to install WiMax 4G towers at the retailer’s store locations to bring the next-generation mobile broadband technology to customers. Sprint has already begun its 4G roll-out ahead of rivals Verizon Wireless and AT&T and the latest move could add more 4G footprint, increasing its WiMax coverage map.
