Interoperable Satellite Radios

The satellite radio world is divided among the 2 major broadcasters, XM Radio and Sirius. Since they work on different frequencies and need particular equipment to send out, Sirius and XM Radio have divided the market into 2 groups. While some are fans of the Sirius channels others like XM Radio, and the discussion regarding which of the 2 is the best could go on for good.

Some however are customers to both services, since they adore some of the Sirius programs but also enjoy XM Radio broadcasting. For them and for more people interested in satellite radio, there are some potential excellent news. Interoperable satellite radios are one of the things almost all of the big players in the satellite radio industry are talking about. What are they? Fundamentally they're receivers that will work both with Sirius and XM Radio and everything is enclosed in a single unit.

Interoperable Technologies when Sirius and XM work together Interoperable Technologies is the name of a joint effort bankrolled by both Sirius and XM Radio, with the announced point of bringing dual-subscription satellite radios to the general market. Set up in 2003, Interoperable Technologies has started developing the dual-mode satellite radios ever since and progress is being made with each passing month. Interoperable Technologies gets help from experts from both XM and Sirius and their 2005 success of developing a singe unit that will receive both transmissions was an important one.

Today, Interoperable Technologies has a cut-off point of bringing the developed receiver unit to the market. The regular subs price is projected to be around $26 for which you get over three hundred channels from the mixed broadcasting list of the 2 satellite radio operators. What the people say... The news of the interoperable satellite radio development has triggered fascinating replies among XM and Sirius satellite radio customers.

How Does Satellite Radio Work?

Satellite radio is among the largest enhancements in broadcasting since the advent of FM. Satellite radio signal can be broadcasted for over 35,000 kilometers ( 22,000 miles ) with complete clearness and top of the range sound. You may never get static interferences while listening to over 100 radio channels. The concept behind satellite radio has appeared in 1992, when the US Fed Communications Commission granted a spectrum of the S band ( the 2.3 GHz frequency ) for Digital Audio Radio Service. The license to send out in that band was allotted to Sirius Satellite Radio and XM Satellite Radio in 1997. Now there are three corporations that provide satellite radio in the world : Sirius and XM in Northwards America and WorldSpace in the East, Europe and Africa. Each of these companies offer different broadcasting systems, since the radio signal of each is proprietary.

This suggests that you'll have to buy different hardware dependent on your subscription to one of those firms. there are 3 elements common to all satellite radio services : the satellites, the ground repeaters and the radio receivers. Different satellite radio companies broadcast the radio signal in alternative ways.

As an example, XM satellite radio uses geostationary satellites which have orbits that are synchronized with the movement of Earth. These satellites are found above the equator. So as to allow customers to get clear as crystal signal notwithstanding barriers like buildings, hills or bridges, XM satellite radio service has installed a structure of repeaters antennas that receive the radio signal from the satellites and retransmit it to the subscriber's receiver Sirius, from another viewpoint, uses satellites that have unique elliptical orbits around Earth. These types of orbits permit satellites to get higher in the sky than geostationary satellites and this hinders loss of signal. This is the reason Sirius has less earthly repeaters than XM. Satellite radio services have digital broadcast centres where a big quantity of music in digital format as well as CD format is stored. Radio programmers have the job of choosing which song must be played at which time. There also are lots of studios managed by digital radio firms where artists perform live. All songs and material are broadcast to the satellites in digital format so the signal contains terribly high quality sound. The signal is encoded by the satellite and then retransmitted to the repeaters antennas, which then broadcast it to the radio receiver which decodes it and plays the sound. The whole process is really fast and trustworthy.
