Deutsche Telekom, Ericsson top 100 Gbps Speeds Over Microwave Link

By The Editors of AGL

Ericsson and Deutsche Telekom have consistently topped 100 Gbps in a microwave trial using a link over a little less than a mile. Conducted at the Deutsche Telekom Service Center in Athens, the joint innovation project achieves more than 10 times greater throughput speeds than current commercial solutions on similar 70/80 GHz millimeter wave spectrum.

Alex Jinsung Choi, SVP Strategy & Technology Innovation, Deutsche Telekom, said the trials will be a big change in solutions for future fronthauling capabilities.

“Advanced backhaul solutions will be needed to support high data throughput and enhanced customer experience in the 5G era,” Choi said. “This milestone confirms the feasibility of microwave over millimeter wave spectrum as an important extension of our portfolio of high-capacity, high-performance transport options for the 5G era. In addition, it Apart from confirming the potential of microwave technology over millimeter-wave spectrum (70/80 GHz and above) as a 5G-and-beyond fronthaul and backhaul solution, the trial showed the importance of applying spectral efficient techniques, such as MIMO (multiple input, multiple output) on wireless backhaul technologies to address upcoming 5G radio access demands.

Per Narvinger, head of Product Area Networks, Ericsson, said,  this trial proves that microwave can provide of capacities equal to fiber.  “This means that microwave will be even more relevant for communications service providers in creating redundant networks as a back-up for fiber, or as a way of closing a fiber ring when fiber is not a viable solution. By carrying such high capacities, microwave further establishes itself as a key transport technology, capable of delivering the performance requirements of 5G,” he said.

Technical details

Key technological advances included an 8×8 line-of-sight MIMO with cross polarization interference cancellation setup using commercial MINI-LINK 6352 radios and a 2.5 GHz channel bandwidth in the E-band (70/80 GHz) able to transmit eight independent data streams over the radio path. This corresponds to a breakthrough spectrum efficiency of 55.2 bps/Hz at peak.

During the mid-April trial, transmission rates measures were consistently above 100 Gbps, with telecom grade availability (higher than 99.995 percent), with peak rates reaching 140 Gbps.

In late 2018, Ericsson and Deutsche Telekom broke the 40Gbps barrier fully using commercial equipment including Ericsson’s MINI-LINK 6352 solution, which currently provides 10Gbps capacity over a 2000MHz channel. To raise throughput by more than 10 times, this trial used a 2500MHz channel and pre-commercial baseband and MIMO processing equipment in addition to MINI-LINK 6352 radios.

The Future of Microwave Backhaul Is Smaller

By Adrian Laidlaw

Long haul microwave links typically use large antennas – anywhere from 6 feet to 12 feet in diameter – which creates some significant issues in link design and installation.  The larger the antenna, the greater the wind load on the tower and also the narrower the antenna beam width for a given frequency. This potentially means that towers need to be strengthened and stiffened to allow the antenna to remain aligned or there may be restrictions on where the antenna can be mounted.

New developments in antenna design and technology are leading to increased gain and smaller diameter sizes. Where the ability to install links may be determined by interference rather than simple gain, improved radiation pattern envelopes such as those compliant to ETSI Class 4 can allow smaller antennas to be deployed. Costs can be lower because of basic product costs and from savings in potential tower modifications.

In a world where real estate of all types is becoming more expensive, microwave antennas are no exception. The potential to drop a size bring benefits to operating costs over the lifetime of the link in regards to tower rental costs. Being able to deploy a smaller antenna can lead to savings way beyond the initial purchase price.

One extra positive in using a smaller antenna is happier installation teams. The larger the antenna the more skill, care and attention is need to getting it hoisted up the tower, fitted onto its mounting structure and aligned. The smaller the antenna the easier it is to install. With less time required for assembly, the rigging operation gets done quicker.

Check out CommScope’s next-generation HX and USX long- haul microwave antennas to see what I mean. Both of these antenna families provide considerable improvements in performance over other equivalent products currently being deployed.

NEP Cellcorp Backhauls LTE Network with Exalt Microwave

Exalt systems are easy to deploy and deliver high, scalable bandwidth
 
CAMPBELL, Calif. — September 18, 2013 ­ Exalt Communications, Inc., the leading innovator of next-generation packet microwave backhaul systems, today announced that NEP Cellcorp of Forest City, PA has deployed Exalt ExploreAir microwave systems to backhaul LTE cellular traffic in its network.
 
A subsidiary of North-Eastern Pennsylvania Telephone Company, NEP Cellcorp serves wireless customers in Susquehanna and Wayne counties. As many of the cell sites supporting subscribers in these counties are outside the limits of North-Eastern Pennsylvania Telephone’s wireline network, NEP Cellcorp selected Exalt microwave backhaul systems for cell site backhaul rather than leasing lines from another provider. The Exalt systems deliver high bandwidth with high reliability, and are software upgradeable to transport up to 1 Gigabit per-second (Gbps) of Ethernet traffic.
 
“When we began extending our LTE network in April to the edges of our service area, we knew that microwave backhaul was the best choice for us,” said Rick Kulasinsky, wireless engineering and operations manager for NEP Cellcorp. “Exalt stood out from other manufacturers because their systems are easy to deploy and can scale to meet all of our bandwidth needs into the future.”
 
The all-outdoor Exalt ExploreAir systems operate in the licensed 11 GHz frequency band, and currently deliver up to 300 megabits per-second (Mbps) of Ethernet bandwidth. The zero-footprint, all-outdoor design of the Exalt systems simplifies deployment.
“To remain competitive and better serve their subscriber bases, regional cellular providers like NEP Cellcorp need to look for a better way to expand their networks and increase network performance than relying on leased lines that are costly and do not scale,” said Joe Schraml, Exalt vice president of product line management. “But all microwave backhaul systems are not equal. Exalt offers these providers the broadest choice of system options, all of which deliver high performance, pay-as-you-grow scalability, and ease of deployment – capabilities that lower total cost of ownership and improve bottom line results.”
