ELVA-1, manufacturer of wireless communication equipment, has introduced a full-duplex 10 Gbps Series of Q-band (40.5 to 43.5 GHz) and E-band (71 to 76/81 to 86 GHz) mm-wave radio bridges. The PPC-10G broadband link provides full-duplex data rates of up to 10 Gbps in a single, zero-footprint, all-outdoor solution. Its maximum operating distance is up to 20 km (12 miles) for links equipped with 2 ft. antennas. The link is intended for use in point-to-point applications such as 4G/LTE Backhaul, Corporate Campus Networks, IPTV, and Wireless ISP backbone.
The PPC-10G 10-Gig millimeter wave platform is based on state-of-the-art MMIC chips, which support QAM 256 (Quadrature Amplitude Modulation) in digital data radio communications. QAM 256 modulation uses 8 bits per symbol. Using QAM 256, PPC-10G requires only 2 GHz of bandwidth for its 10 Gpbs data rate.
One of the key features of PPC-10G is Adaptive Code and Modulation (ACM) support. In rainy conditions, its built-in ACM retains connectivity by decreasing link throughput. It adapts the modulation scheme to obtain the highest data rate for the given conditions. By reverting to lower-order modulation schemes of 128 QAM, 64 QAM, 32 QAM, 16 QAM or 8 QAM, the link can support a reliable connection, even in heavy rainfall. As the weather clears, throughput automatically increases to maximum.
One advantage of millimeter wave technology is that up to four PPC-10G parallel links may be installed at the same point-to-point locations, and aggregated into one 40 Gbps channel with no mutual interference.
With unparalleled capacity in the wireless link market, ELVA-1's PPC-10G is available in either the licensed 40.5 to 43.5 GHz (Q-band) or the lightly licensed 70/80 GHz (E-band) frequency formats with 1 ft. or 2 ft. antennas. It utilizes Ethernet protocol, which is the evolving standard for switches and routers available from a variety of telecommunication equipment manufacturers. This device is a fully-outdoor radio link, designed for temperature variations between -50°C (-58F) and +65°C (+150F), and humidity up to 100%.
These links can also be equipped with built-in high-grade, high-performance Ethernet level 2 switches with advanced configuration options, including support for SyncE and IEEE1588v2 (TC, BC), as well as CPRI (Common Public Radio Interface) for up 9.8 Gpbs connectivity.
