The iQ Desktop+ is part of iDirect’s DVB-S2/S2X remote series based on a future-proof hardware with software-defined architecture for maximum flexibility and expansion. The iQ Desktop+ is highly scalable and ideal for broadband access and small enterprise mobility applications and is compatible on both Evolution® and iDirect Velocity®.

The iQ Desktop+ features dual Gigabit Ethernet VLAN-aware networking ports and a very small form factor ideal for prosumer, broadband access, and small enterprise site networks supporting a large range of fixed and mobile applications including Internet/Intranet access, SCADA, Voiceover-IP (VoIP), video streaming, and multicasting. The iQ Desktop+ can reach throughputs up to 200 Mbps when being used in L2oS mode and is compatible with a variety of ODU configurations. The modem’s high performance modulation techniques enable network operators to offer various bandwidth intensive services in a cost-effective way. Packaged in a professional grade metal enclosure, this modem can operate at an extended temperature range up to 50 degrees Celsius.

The iQ series modems are also available as a 1U rackmount or board level product.
