The FCC (News - Alert) is taking a second look at restrictions previously placed on 2.3 GHz high-speed broadband solutions. These restrictions limited the ability for licensees to use Wireless Communications Service (WCS) with that frequency for wireless broadband solutions and offer other services at the same time.
The constraints were prohibitory for businesses wanting to utilize both broadband wireless services while simultaneously shielding receivers for Satellite Digital Audio Radio Service (SDARS) from catching interference.
In response, the FCC mandated an Order on Reconsideration FCC 12-130, which eased the limitations placed on users of 2.3 GHz frequencies. The order comes on the heels of a concession made between AT&T (News - Alert) and Sirius XM Radio not long ago over the fight for access to the broadband solutions spectrum.
AT&T faced opposition from Sirius XM Radio for 15 years because of allegations that using spectrum for its 4G LTE (News - Alert) network caused interference with Sirius’s satellite radio programming.
As information at CNET points out, the two giants finally came to an agreement, and the FCC accepted their proposal to set aside unused bands of spectrum next to those used by Sirius as a means of protecting the integrity of satellite radio offerings.
Per the new FCC revision, as outlined in an article featured at TV Technology, a total of 30 MHz of the 2.3 GHz allotted bandwidth is allowed for total broadband solutions – 20 MHz has been set aside for mobile broadband services while the remaining 10 MHz will be used to accommodate fixed broadband offerings.
Currently, SDARS utilize the middle of the 2.3 GHz bandwidth at 2320-2345 MHz, and WCS employs the spectrum ranges of 2305-2320 MHz and 2345-2360 MHz.
Additionally, with the new Order, WCS licensees will be given more grace when it comes to deadlines for completing construction. The revised FCC guidelines allow construction periods for WCS to be reset, allowing licensees time to adapt to the looser legislation without losing focus on expanding operations in the short term.
The new updates also aid Sirius XM by helping to minimize the occurrence of damaging interference to SDARS signals, which are projected to vehicles traveling on the highways. The removal of barriers to licensee notifications for low-power terrestrial repeaters and for minor modifications to repeaters is another way that Sirius XM benefits from the Order.
However, the FCC refrained from interjecting changes to licensing requirements for high-power SDARS terrestrial repeaters which are not covered by blanket licensing.
On average, WCS fixed locations receive no more than 2,000 watts of power for every 5 MHz in spectrum. The regulations on power for transmitters utilizing the WCS broadband solutions bands are complex and vary based on locality and out-of-band emission performance.
