The Wireless Internet Service Providers Association (WISPA) is calling on the FCC to take an active role in ensuring LTE-U and LAA technologies play nice with Wi-Fi and other unlicensed technologies.

In summarizing the comments received so far, WISPA praised equipment manufacturers’ willingness to push for coexistence between LTE-U and other unlicensed technologies but warned that simply wanting coexistence won’t be enough.

“WISPA appreciates the good faith of these companies in seeking to accommodate different technologies in unlicensed spectrum, but respectfully notes that it will require more than just benign intentions to achieve this optimal result,” WISPA wrote in an FCC filing.

The Association also said that carriers like T-Mobile and Verizon, which are both moving ahead with LTE-U deployments ahead of 3GPP’s release 13 standard, should not be allowed to deploy without hands-on FCC oversight.

“Optional inclusion of co-existence protocols is a prescription for disaster, not competition, especially when the licensed proponents have little incentive to cooperate with unlicensed users,” WISPA wrote.

In addition to reiterating the call for listen-before-talk and exponential backoff protocols built into the standards, WISPA said the FCC should closely monitor the standards setting process. The Association agreed with NCTA’s suggestions for how the FCC should approach LTE-U/LAA deployments and insisted that the FCC should be ready to intervene those technologies pose a threat to existing unlicensed technologies.

"Commission monitoring of the standards-setting process will not upset the principle of technology neutrality by "tilting the scales in favor of' one technology or another,” WISPA wrote. “To the contrary, agency participation is essential to ensure that the standards ultimately adopted do not themselves skew the competitive landscape unduly in favor of one category of users.”

In separate reply comments, CTIA, representing Verizon and other wireless providers, insisted the FCC maintain its technology neutral approach toward the development and implementation of unlicensed technologies. CTIA also said the FCC should allow the standards process to proceed with regulatory intervention.
