ELVA-1, the European manufacturer of ultra-high capacity millimeter wave point-to-point wireless links, has announced the availability of its flagship PPC-10G, 10 Gbps Ethernet radio link, to the United States market. Gilland Electronics, of Morgan Hill, Calif., has begun taking orders for this outstanding new product.
A publicity product launch in St. Petersburg, Russia in July 2016 was followed by an event in London in early August that was presented by RF Com, ELVA-1’s UK representatives. At the London event, a link was set up to carry live wireless traffic over the Thames River, and several attending UK and international mobile operators expressed interest in the system for wireless backhaul, especially as they plan for deployment of 5G network backbones. RF Com’s Managing Director, Ian Cains, said of the London event, “This event demonstrates that it is now possible to offer a solution for providing the fastest, most accessible networks anywhere in the world. We are extremely enthusiastic about working with ELVA-1 on embedding this technology into the UK and European markets.”
The PPC-10G 10-Gig millimeter wave platform is based on state-of-the-art MMIC chips that support QAM 256 (Quadrature Amplitude Modulation) in digital data radio communications. QAM 256 modulation uses 8 bits per symbol. Drawing upon its lengthy experience in the design of precision low noise mm-wave scientific instruments, ELVA-1 has pioneered the implementation of QAM 256 technology for E-band to achieve the best spectrum efficiency in the industry. Using QAM 256, PPC-10G requires only 2 GHz of bandwidth for its 10 Gpbs data rate, making it the highest technically achieved spectrum efficiency of any commercial E-Band link.
Another advantage of ELVA-1’s 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. PPC-10G utilizes Ethernet protocol, which is the evolving standard for switches and routers available from a variety of telecommunication equipment manufacturers.
One of the key features of PPC-10G is Adaptive Code and Modulation (ACM) support. In rainy conditions, the PPC-10G’s built-in ACM retains connectivity by decreasing link throughput. It adopts the modulation scheme required to attain 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.
With unparalleled capacity in the wireless link market, ELVA-1’s PPC-10G is available in either licensed 40.5-43.5 GHz (Q-band) or lightly licensed 70/80 GHz (E-band) frequency formats with 1 ft. or 2 ft. antennas. Using a 2 ft. antenna, average link range is up to 4 miles for the Northeastern and Mid-Atlantic regions of the United States, with a 10+ mile maximum in the drier Southwest and inland areas of the West.
The ELVA-1 PPC-10G is a fully-outdoor radio link, designed for temperature variations between -50°C (-58F) and +65°C (+150F), and humidity up to 100%. In very cold regions, the advantage over free space optical links is very clear, because in addition to having a range approximately 10x longer, PPC-10G is not affected by most snowstorms. Normally mounted on a rooftop or tower, the PPC-10G contains slots for SFP/SFP+ modules to connect to a LAN or WAN, and it is equipped with remote management capability, to control operability over the Internet.
As an option, PPC-10G links can be equipped with built-in high-grade, high-performance Ethernet level 2 switches having 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. PPC-10G links can provide unprecedented infrastructure data stream support for 4G-5G/LTE backhaul, private high-capacity networks, IPTV, Wireless ISP, and quick-setup optical fiber replacement or disaster relief communications.
According to John Stover, President of Gilland Electronics, “In the United States, telecom operators are already envisioning the advanced mobile architecture required for successful network operations in 2020. This includes wireless backbone and backhaul for both mobile and fixed broadband services. We will work closely with carriers and service providers to bring the advantages of 10+ Gbps E-band wireless throughput within their grasp as quickly and economically as possible.”
