Wireless Broadband Alliance and Wireless Global Congress

Earlier this year ASSIA was invited to join the Wireless Broadband Alliance (WBA) and to participate in the WBA Working Group sessions at the Wireless Global Congress on May 20 -23 in Atlanta. The WBA is a complimentary organization to the Wi-Fi Alliance:

  • The WBA specifies roaming between operators’ Wi-Fi networks (hotspots) and the use cases for operators to manage Wi-Fi services.
  • The Wi-Fi Alliance defines the 801.11 specifications which are the basis for how devices connect over Wi-Fi.

The Wireless Broadband Alliance has over 100 members—most of the world’s leading service providers—and has reached out to key vendors as they work to develop in-home Wi-Fi industry guidelines and test cases for the next generation Wi-Fi 6 (802.11ax), which is coming out in 2019. Of course, this also involves the coming together of LTE/5G and Wi-Fi/LAN technologies in which the WBA 5G Working Group is active. In addition, the WBA IoT Working Group is involved in the many use cases that involve the movement from fixed to mobile (in vehicle scenarios), vehicle to vehicle, and Wi-Fi sensing.

Panel: Future of In-Home Wi-Fi—From IoT to Next-generation In-home Wi-Fi Experience

The Wireless Broadband Alliance asked ASSIA to participate in the industry panel “Future of In-Home Wi-Fi— from IoT to next-generation in-home Wi-Fi experience” at the Wireless Global Conference Atlanta with representatives from AirTies and Cognitive. During the panel, I had the chance to share some of the work ASSIA has been doing that leverages our years of experience managing and optimizing broadband to the home. As the industry transitions to broadband to the device across a mix of technologies, and as Wi-Fi expands from a single access point in the home to multiple access points and mesh topologies, I focused on how ASSIA is:

  • Supporting multiple services in the home spanning voice, video, AR and IoT
  • Participating in the early rollout of Wi-Fi 6-capable access points
  • Building an intelligent cloud-based system that can take real-time action to ensure an excellent quality of experience for the end user

Wireless Broadband Alliance

The Wireless Broadband Alliance is certainly an interesting organization to be part of.  They are helping us understand and anticipate real world problems so we can build and test solutions that make a real difference to service providers including:

  • Helping to reduce operations costs by reducing the number of service call and field visits
  • Maximizing the return on investment by minimizing CapEx to only target the things that make a difference
  • Improving customer satisfaction, reducing churn, and encouraging purchase of additional services

I look forward to ongoing engagement and continuing to form partnerships to help push the industry forward.

Marconi Society 2019 Awards Dinner

It was privilege to attend the Marconi Society Awards Dinner on May 17th which honored the 2019 Marconi Prize Winners Taher Elgamal and Paul Kocher for their development of SSL/TLS as well as other contributions to the security of communications. The event was well attended by many well-known people who have made huge contributions to the advancement of communications technologies.

Attendees included Vint Cerf who is known for the design of TCP/IP and is one of the “fathers of the internet”, James H. Clark who was a founder of several Silicon Valley companies including Netscape Communications Company where the 2019 prize winners developed the security to enable on-line purchases, Robert Lucky who led Telcordia Technologies’ building of the Automatic Adaptive Equalizer, and of course John Cioffi who founded ASSIA after his pioneering research that helped create Digital Subscriber Line circuits that bring broadband Internet access to hundreds of millions of people.

It was extraordinary to be in a room with so many of the people who built the modern communications technologies we use every day and to see them not only honoring their peers, but also encouraging the next generation of innovators from all over the world who are working on MIMO (Multiple-Input-Multiple-Output) transceiver architectures, networks to support IoT applications, and NOMA (Non-Orthogonal Multiple Access) technologies with the Paul Baran Young Scholars Awards.

The Marconi Society is a great organization and the Marconi Society Awards very worthwhile.
