Chicago Conditional Access Traffic Test Called a Success

A test of HD Radio conditional access traffic data services in Chicago has concluded successfully, according to organizers.

The results were first reported on RW’s “The Leslie Report” earlier this month. The companies have now issued a press release announcing the same.

Broadcast Electronics, Emmis Communications and NDS conducted the project, with involvement from Ibiquity Digital Corp. Testing was at Emmis station WKQX(FM).

“Pilot testing occurred May 23 and 24 and was the first conditional-access test for broadcasting real-time traffic information over the HD Radio system to vehicle navigational systems,” BE stated.

Initial testing addressed the ability of broadcasters to allocate bandwidth and protect content for mobile delivery of traffic information, it said.

BE and NDS, a conditional access technology supplier, provided an HD Radio system including NDS encryption and bandwidth provisioning by BE’s IDi 20 HD Radio importer unit.

The test involved maps and real-time traffic content and included authorization and de-authorization of the receiver for the data service, testing of system functionality, reception/decryption of traffic data at the receiver and recording and logging of data to determine latency and data stability in the encrypted channel.

“Test drives in various multipath environments around the Chicago area showed no dropped data packets or loss of service,” BE reported.

This is so simple Anything that changes the law after the application is submitted is "ex post facto" law and as such is unconstitutional. The federal government is prohibited from passing ex post facto laws by clause 3 of Article I, section 9 of the U.S. Constitution. As such, such changes (such as mandatory caps) will be the source of unending lawsuits, which is in no one's benefit (except the attorneys), and the spectrum will remain fallow. These applications have been submitted in good faith and must be processed. However, by simply letting the applicants modify their filings and communicate (even negotiate) settlements would resolve most of the applications and the law at the time of filing would easily resolve the remainder. That law says any commercial applications go to auction with all other commercial applications in that Mx group and any noncommerical applications in groups that also contain commercial applications must be dismissed. The remaining noncommerical groups are processed by a point system. As to LPFM, let them apply using existing, well established translator rules, including 250 watts at low elevations, directional antennas for contour protection and D/U protection of 2nd and 3rd adjacent stations. There are plenty of free frequencies using those rules and thousands of LPFMs could be created. The current LPFM spacing rules are very poor and restrictive and should be abandoned, since they allow very few new stations (even if all translator applications were dismissed) and still result in unacceptable interference in many situations.
