Verizon, T-Mobile oppose delaying LTE-U to test WiFi interference claims

Companies such as Microsoft and big cable companies support further testing. Microsoft said it worries that the LTE-U signal could "degrade the performance of services delivered over Wi-Fi." Big cable TV and Internet companies are worried that their investments in Wi-Fi hot spots throughout the country could be greatly impacted if there is interference from LTE-U. "Research demonstrates that both LTE-U and LAA would severely decrease the performance of any nearby Wi-Fi network. Widespread deployment of LTE-U or LAA would therefore harm American consumers, schools, and innovators by dramatically reducing the utility of the unlicensed bands for everyone but the companies that already hold licensed spectrum," the NCTA said in its letter to the FCC. "Furthermore, there is already a growing amount of research, such as that published by Google and CableLabs"indicating that Wi-Fi networks will be negatively impacted by the current version of LTE-U technology. The risk to users who depend on Wi-Fi every day for their connectivity needs is too great."
