Product Description
The MDM3315 Satellite Modem is supported on multiple platforms to
cover the widest range of markets and applications. The modem shares
a wide range of key features and can be easily mixed in a single satellite
network on either Velocity or Dialog platforms. The modem is extremely
flexible, as it can leverage several different return waveform technologies
across multiple platforms: ATDMA, MF-TDMA, high-rate SCPC and Mx-
DMA MRC, which seamlessly combines MF-TDMA flexibility with on-
demand variable bandwidth allocation of SCPC while guaranteeing the
highest efficiency and availability. The MDM3315 also supports wideband
operations up to 500 Msps in the forward channel, enabling service
providers to set-up any type and size of network on HTS/VTS.
The modem supports a wide range of fixed IP services, including
Internet/ intranet access, VoIP, enterprise connectivity, maritime, and
multicasting services. With data rates up to 150/70 Mbps, the MDM3315
can also be used in backhauling applications. The wideband receive
capability makes the MDM3315 a perfect fit for usage on HTS satellites.
The modem’s ease of installation through multilingual web GUIs allows
service providers to deploy their services quickly, in a cost-effective way.
