AT&T transmits 5G from Flying COW

AT&T recently demonstrated a 5G "Flying COW" (Cell on Wings) over a quiet, non-descript field in rural Missouri.

“We had intermittent, weak LTE signal at the flight location before we launched the 5G Flying COW,” said Ethan Hunt, Unmanned Aircraft Systems (UAS) Principal Program Manager, AT&T. “We flew the drone up to about 300 feet, turned on the signal and it began transmitting strong 5G coverage to approximately 10 square miles.”

AT&T says the drone could be used to quickly set-up 5G service for first responders in a search and rescue mission.

“Our focus within the drone world is connectivity. All of our drone solutions have that focus,” said Art Pregler, Unmanned Aircraft Systems (UAS) Program Director, AT&T. “5G brings a lot of new capability to the table. We can connect a lot larger number of devices with 5G. When we put that up, we can share with a larger population.”

AT&T also highlighted two other drone projects:

  • Beyond Visual Line of Sight (BVLOS) flight operations, GEOCAST air operations -- this would allow the pilot to operate a drone from a completely different location. An AT&T-patented flight control system  allows  operators and  tethered Flying COWs to be separated by thousands of miles.  In the next phase, AT&T will launch untethered Flying COWs.
  • 5G RoboDogs -- which could be used for a number of situations, such as search and rescue or bomb disablement.

OIF advances Common Management Interface Spec (CMIS)

The OIF has released a Common Management Interface Specification (CMIS) Implementation Agreement (IA). 

CMIS provides a well-defined mechanism to initialize and manage optical and copper modules in a standard way, while still providing the capability to provide custom functionality. This commonality makes integration into different host platforms easier for both the host and module vendors.

IA—CMIS 5.2:The importance of CMIS continues to expand as higher-speed systems require more complex modules demanding more sophisticated management interfaces. This IA marks the first OIF-approved CMIS IA and the completion of the transition of the work to OIF.

“One of the reasons OIF adopted the CMIS work is its close coupling and application to ongoing OIF projects,” said Ian Alderdice, Ciena and OIF Physical & Link Layer Working Group – Management Co-Vice Chair. “This IA includes new features supporting a wide variety of form factors, most importantly fiber channel enhancements which expands the range of end-user applications.”

At its Q2 2022 Technical and MA&E Committees Meeting, which was held last month, a new CMIS project was also intiated. CMIS addresses commonality in managing pluggable modules and is a critical interface working hand-in-hand with other OIF areas, including co-packaging and electrical. The project work to create the next version of CMIS will add the necessary support for co-packaging/External Laser Small Form Factor Pluggable (ELSFP) projects and link training.

“This new project work represents the next steps in the evolution of CMIS and its alignment with other OIF PLL Working Groups tracks to enable an interoperable ecosystem,” said Gary Nicholl, Cisco and OIF PLL Working Group – Management Co-Vice Chair and Secretary/Treasurer.

OIF adopts Common Management Interface Specification (CMIS) 

OIF has adopted the Common Management Interface Specification (CMIS) work initiated by the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA).  

CMIS may be used by pluggable or on-board modules, such as QSFP Double Density (QSFP-DD), OSFP, COBO, QSFP, and future module developments like co-packaged optics with host to module management communication based on a two-wire interface. This specification is targeted to systems manufacturers, system integrators and suppliers of CMIS compliant optical and copper modules. 

“The QSFP-DD MSA initiated the CMIS effort to address an industry need for commonality in managing pluggable modules, and it has been broadly and successfully adopted across the industry,” said Mark Nowell, Cisco, QSFP-DD MSA Group founding member and MSA co-chair. “OIF is very well suited to maintain and extend the development of this effort and I look forward to seeing their progress.”

“Adopting CMIS from the QSFP-DD MSA, with the goal to build on and extend the specification is an ideal expansion of OIF’s work,” said Nathan Tracy, OIF VP of Marketing and TE Connectivity. “OIF is where the cloud gets its work done and extending CMIS is a giant step forward and an integral linkage to the other work that OIF members are doing to enable an interoperable ecosystem.” 

In August, OIF announced the new Physical & Link Layer (PLL) Working Group Management track to include the transition of ownership and maintenance of CMIS from the QSFP-DD MSA to OIF and a project to focus on CMIS extensions for co-packaging implementations. OIF will take over the ongoing CMIS revisions and further enhancements and CMIS extensions under this track. This track is co-vice-chaired by Gary Nicholl, Cisco and Ian Alderdice, Ciena.

Credo ships 40G PAM3 SerDes

Credo Technology Group announced availability of its Ostrich 40G, PAM3 Serializer/Deserializer (SerDes) PHY/PMA Intellectual Property (IP). 

Ostrich is a multi-protocol high-speed SerDes supporting data rates up to 25.6Gbps NRZ and 40Gbps PAM3. A single bi-directional lane supports channel insertion loss up to 30dB bump-to-bump at 40Gbps with spread-spectrum clocking (SSC) enabled while achieving very low power to address all key application use cases. Credo's unique SerDes technology enables silicon solution providers and OEMs to manufacture custom chip solutions which address new market opportunities, while delivering on critical performance and low- power system level requirements.

Credo says unique mixed signal approach was first applied with the move from NRZ to PAM modulation when Ethernet connectivity jumped from 25G to 50G. With new applications demanding two times the throughput, and current single-lane data rates maxing out in the 20G to 32G NRZ performance range, the move to advanced modulation schemes enables higher performance at the lowest possible power. To enable 40Gbps performance the company determined that PAM3 offered the best overall balance of performance and power.

Bill Brennan, Credo’s President and Chief Executive Officer stated: “The data infrastructure market is experiencing an exponential increase in bandwidth demand. There is a revolution happening as new markets and standards, including those for applications such as consumer devices, small-to-medium sized business, automotive and others demand higher-speed connectivity at lower power. Credo is addressing the expansion of the connectivity ecosystem by delivering industry-leading performance with advanced IP solutions like our Ostrich 40G PAM3 SerDes, while in parallel providing complementary IC product solutions."

Sony establishes a Space Communications company

Sony Corporation of America has formed a new company, Sony Space Communications Corporation (SSC), to offer small optical communications devices for connecing micro satellites in LEO via a laser beam. 

By using optical communications, SSC aims to realize high-speed communications with small devices, which are physically difficult to achieve with conventional radio communications because conventional communications require large antenna and high power output. In addition, by constructing an optical communications network not only between satellites and the ground, but also between satellites in orbit, SSC aims to enable real-time communications from anywhere on the ground to any satellite in space. 

"Currently there are approximately 12,000 satellites in space, and the number is expected to increase in the future. The amount of data used in orbit is also increasing year by year, but the amount of available radio waves is limited," said Kyohei Iwamoto, President, Sony Space Communications Corporation. "Low Earth Orbit (LEO) satellites need to communicate with the ground, so a large number of communications facilities are required for real-time communications, which is problematic because these satellites must pass directly over a ground station to communicate with it. Additionally, the need for frequency licenses for radio waves and the requirement for lower power consumption of communication equipment needed by smaller satellites, like micro satellites, are also issues to be addressed."
