Acceleration technology to fill emerging demands of satellite cellular backhaul

March 07, 2017 // By Jean-Pierre Joosting
Hughes Network Systems, LLC (Hughes) has introduced its next evolution of JUPITER System technology, which includes advanced LTE acceleration to support cellular backhaul requirements for mobile network operators and VSAT service providers as they expand their cellular services into areas without suitable terrestrial backhaul.

The Hughes HT2500 terminal, is a next-generation satellite terminal that has native support for accelerating LTE protocols. With support for over 7,500 simultaneous TCP sessions, the terminal is able to deliver accelerated performance for many devices connected simultaneously to the LTE eNodeB. Speeds of 200 Mbps enable the HT2500 to deliver the LTE performance required by mobile operators around the world.

Recognizing that satellite networks supporting cellular backhaul will often start out small and scale over time, Hughes is also introducing the HG220 gateway configuration to cost effectively address such small networks. The HG220 supports up to 5 networks over up to 5 satellites and with extensive QoS, IP features and bandwidth management options, the HG220 gateway and the HT2500 terminal provide an effective solution for satellite cellular backhaul links. The HT2500 and the HG220 utilize the JUPITER System's wideband DVB-S2X forward channel, the most efficient in the industry, with support for 5 percent channel roll off as well as 64APSK modulation.

Vinay Patel, manager of the cellular backhaul product line at Hughes, explained, "Our JUPITER System with LTE acceleration enables mobile operators worldwide to expand their networks with high-performance satellite backhaul links that are 40 to 60 percent more efficient than those previously available. This advanced technology builds on our broadband heritage around the globe and will continue to bridge the digital divide and improve economic and social development."
