Fully Integrated Within WORK Microwave DVB-S2 Modems and Modulators, Roll-Off Feature Enables Operators to Achieve Significant Bandwidth Gains
HOLZKIRCHEN, Germany -- Aug. 30, 2012 -- WORK Microwave, a leading European manufacturer of advanced satellite communications equipment, today announced that it has added a sophisticated new digital filter with a roll-off factor of 5 percent to its comprehensive range of DVB-S2 modem and modulator solutions. Utilizing the roll-off feature, corporate network and Internet service providers, government networks, and satellite operators can maximize the bandwidth of their DVB-S2 networks to more efficiently deliver a high quality of service.
"Satellite operators have only recently allowed a roll-off smaller than the 20 to 35 percent that DVB-S2 allows," said Joerg Rockstroh, senior R&D engineer, WORK Microwave. "Leveraging our more than 25 years of experience creating cutting-edge communications technologies, WORK Microwave quickly developed a much smaller roll-off of 5 percent, enabling service providers to maximize the size of their carriers in order to optimize bandwidth use."
Roll-off technology minimizes unused space between satellite carriers, enabling an operator to support a wider carrier or additional carriers. Utilizing WORK Microwaves innovative new roll-off feature, operators can achieve up to a 15 percent bandwidth gain on top of the DVB-S2 standard, after increasing the power of their modem or modulator in order to compensate for the wider carrier. Alternatively, operators that are unable to increase the power of their modem or modulator can still achieve an 8 to 15 percent bandwidth gain -- depending on whether a change in MODCOD is necessary. Both methods offer a significant improvement in bandwidth allocation compared with the 20 to 35 percent roll-off provided by the DVB-S2 standard, thereby dramatically reducing a users operational expenses.
Modems and modulators that include the roll-off feature can be used in any operating environment, such as a single carrier or shared transponder. A small roll-off, such as 5 percent, allows satellite carriers to be more space-efficient in a multicarrier environment or realize the maximum symbol rate within a transponder in a single carrier per transponder environment --leading to substantial bandwidth gains in either case. When applied to a shared transponder, WORK Microwave technology effectively eliminates interference on neighbor carriers, ensuring a consistent quality of service for end users.
WORK Microwave's comprehensive range of DVB-S2 modems and modulators provide the most reliable method for optimizing throughput and increasing the available amount of bandwidth on any communications network, allowing operators to significantly increase efficiencies while reducing operational and capital expenditures.
