CTIA – The Wireless Association® Responds To M2Z’s AWS Testing “Spin”
September 23, 2008
WASHINGTON, DC – CTIA - The Wireless Association® Vice President Christopher Guttman-McCabe, along with engineering consultant Dr. Charles L. Jackson, Ph.D., issued the following statement today in response to M2Z’s Press Briefing on AWS-3 Test Results:
Mr. Guttman-McCabe commented, “On the very day that Google and T-Mobile announced the first Android-based mobile device that will operate on the AWS-1 spectrum, M2Z has taken its AWS-3 advocacy to a new low. First, M2Z claimed there would be no interference to AWS-1. Then, M2Z conceded that there will be interference, but that AWS-1 licensees should have known better. Now M2Z claims that interference – to millions of customers relying upon AWS-1 spectrum – will only happen a small percentage of the time. Tell that to the impacted customers. All of the analysis in the record and the ONLY peer-reviewed testing point to one conclusion: the proposed AWS-3 mobile transmissions will interfere with AWS-1 operations and that interference will be frequent. The success of M2Z’s ‘probabilities’ argument only occurs if M2Z’s business plan and service offerings are an abysmal failure.”
According to Dr. Jackson, “I participated in the recent testing on the impact of proposed AWS-3 mobile transmissions on AWS-1 mobile receptions. Contrary to M2Z’s claims, the testing showed that, in many everyday situations, an AWS-3 handset operating within several meters of an AWS-1 handset would render the AWS-1 handset inoperable. The testing also showed that the FCC’s proposed limit on out-of-band emissions would not protect an AWS-1 handset from out-of-band emissions from a nearby AWS-3 handset. These views are shared by other parties that participated in the testing. In fact, these findings are consistent with analysis M2Z has previously placed in the record. Far from being unprecedented, the testing is entirely consistent with activities previously sponsored by the FCC and with sound engineering analysis.”
Dr. Jackson continued, “To date, M2Z has not conducted any peer-reviewed testing of its own. Nor does M2Z’s advocacy rely on testing performed by other parties. M2Z’s latest presentation is riddled with errors and contradictions, including its outlandish claim that protective AWS-3 rules would prevent WiFi, personal computers, Bluetooth devices, microwaves, and cordless phones from operating near AWS-1 handsets. It is amazing that M2Z’s engineers participated in the AWS-3 testing, had ample opportunities to influence the testing parameters or to request specific tests as did others, and now complain that those testing parameters were inappropriate.”
