22 CapabilitiesNew Wireless testing capabilities Growing wireless communication usage and finite available spectrum bandwidth will continue to limit data transmission quantity and speeds. Idahos isolated landscape provides an unmatched location for full-scale open-air experimentation by those wanting to test options for increasing network efficiency improving security and making more effective use of available bandwidth. INLs experienced communications engineers below help test and evaluate wireless devices and hardware that span high-frequency ultra-high-frequency cellular satellite and microwave. In FY 2012 INL enhanced its Wireless Test Bed by adding 4G capability Mobile WiMAX and completed initial cyber assessments and spectrum interference tests of various 4G systems. The test bed accommodated roughly 250 test days for 11 separate customers last year. It also hosted more than 30 meetings with representatives from regulatory bodies government agencies academia and industry including most major cellular providers and carriers eager to partner with INL to enhance the nations capabilities. Battery testing Expanding light duty electric vehicle use is a sustainable energy priority and battery- based energy storage will help deploy hybrid and renewable energy systems. INL significantly expanded its electric vehicle and stationary battery testing capability with more than 5 million worth of new equipment. A new shaker system subjects prototype and production- ready automotive energy storage devices particularly Lithium-ion battery packs to vibration testing. Such treatment evaluates susceptibility to thermal runaway under normal or extreme conditions and helps improve the overall design robustness. Battery testing enhancements significantly expanded to include large walk-in environmental temperature chambers that accommodate several full-size vehicle battery systems in addition to several dozen smaller chambers for testing small cells and devices.
