AT&T plans to deploy LTE service within the 2.3Ghz Wireless Communication Service spectrum within the next year said John Donovan, Senior Executive Vice President of AT&T technology and network operations. This frequency originally was planned to be used solely for downlink, but now has been redesigned for uplink capability too. To maintain current service levels AT&T uses roughly 10Mhz of new spectrum every 12 months so the 2.3Ghz band can be used to help offload usage in high traffic areas where 700/800/1900Mhz frequencies are overloaded. Right now the company still has enough frequency available to cover current demand and this is simply future planning, but they’ll also be refarming their 2G GSM frequency due to be shut off in 2017. At this time there’s not an official date when handsets will be available with 2.3Ghz capability or when they’ll bring the service into markets across the country.
