Verizon Wireless has achieved peak download speeds of 40-50Mbps on its trial LTE networks in Boston and Seattle. Upload speeds have reached as much as 20-25Mbps, the US operator said. Verizon has been testing LTE since August 2009 and aims to launch the service to 25-30 markets with around 100 million potential users by the end of this year. Successful data calls so far involved streaming video, file uploads and downloads and web browsing, as well as VoIP calls. Verizon Wireless engineers report LTE average data rates of 5-12 Mbps on the downlink and 2-5 Mbps on the uplink in real-world environments. The operator uses the 700MHz band for the new services.
