Aruba launches Passpoint-based Wi-Fi service for mobile operators

Aruba is launching a roaming service for mobile operators that will enable cellular subscribers to securely and automatically roam onto participating Aruba enterprise Wi-Fi networks.

Aruba Air Pass promises a seamless hand-off between cellular and Wi-Fi networks, without sacrificing security or quality of service.

For existing Aruba enterprise customers, the new Air Pass service will use existing enterprise Wi-Fi infrastructure as a cost-effective alternative to deploying indoor small cells or distributed antenna systems (DAS).

When used in conjunction with Aruba Air Slice, an Aruba technology that improves radio performance, telcos can extend their 5G footprint into the enterprise and enable seamless Wi-Fi calling and gigabit-class guaranteed performance.

Aruba believes global telcos will support the service because the enterprise Wi-Fi network effectively becomes a seamless on-ramp and offload point for 5G services.

“The combination of Aruba Air Pass with Aruba Air Slice gives telcos the ability to extend the reach of their 5G networks into the enterprise while economically improving the overall end user experience,” said Jeff Lipton, vice president of Strategy and Corporate Development at Aruba, a Hewlett Packard Enterprise company. “Devices that associate with an enterprise network using Aruba Air Pass may then use their Wi-Fi connections to access applications and services, such as making and receiving calls and text messages, based on their roles and permissions.”

Aruba Air Slice brings to app prioritization to Wi-Fi 6

Aruba introduced a unique Wi-Fi 6 technology designed to provide application prioritization with carrier-grade quality assurance.

Aruba Air Slice leverages the same OFDMA radio technology that powers the 4G LTE and 5G NR radios to dynamically allocate radio resources, such as time, frequency and spatial streams. The company says Aruba Air Slice guarantees performance for latency-sensitive applications such as AR/VR, Zoom and Slack, mobile gaming and real-time IoT applications.

The Air Slice technology is proprietary and builds on top of the Wi-Fi 6 specification. In addition to OFDMA, it leverages MU-MIMO and TWT (Target Wake Time) to allocate resources and extend cellular-grade SLAs and QoS to Wi-Fi connections.

Aruba says Air Slice minimizes airtime contention and efficiently groups Wi-Fi 6 and non-Wi-Fi 6 client devices to guarantee bit rate, and provide bounded latency and jitter simultaneously. Air Slice is available exclusively on Aruba’s Wi-Fi 6 access points via Aruba Central for management.

Cignal AI: North American optical sales rebound in 2019

Sales of optical equipment in North America rose more than 25% for 4Q19 and 10% for all of 2019, according to the most recent Transport Hardware Report from research firm Cignal AI.

The North American packet market for Access and Aggregation routing devices also grew strongly in the fourth quarter as demand for Edge and Core switching and routing dropped off dramatically. 5G and other access rollouts boosted growth in the Access and Aggregation market segment.

“After three years of North American spending declines as operators focused capex on wireless and access, optical hardware sales for the region revived and grew at a healthy pace for 2019, while packet hardware sales remained flat,” said Scott Wilkinson, Lead Analyst at Cignal AI. “Market leaders Ciena, Infinera, and Cisco all achieved optical sales growth of more than 25% in 2019.”

Some highlights:

  • Long haul optical spending reached record levels in 2019. Growth slowed in 4Q19 but the segment finished the year up over 10%.
  • Transport equipment sales in China declined slightly in 4Q19 as packet sales declined and optical sales growth cooled to single digits. When adjusted for the influence of ZTE’s shutdown in 2Q18, optical hardware sales grew less than 10% in 2019.
  • Japan ended an extraordinary year of optical sales growth up 25% in Q4 and almost 40% in 2019.

Fujitsu's TransLambda delivers 3X optical capacity in C-band

Fujitsu Network Communications unveiled TransLambda technology,  an ultra-high capacity, wavelength-division multiplexing (WDM) multiband transmission system (MTS) that substantially expands the transmission capacity of optical fiber networks without deploying new L- and S- band dedicated transceivers.

Fujitsu's TransLambda packs multiple transmission bands into a single fiber using all-optical wavelength conversion (AOWC). TransLambda enables up to three times the capacity for data center interconnect (DCI) and long-haul transport networks. Specifically, TransLambda fiber capacity multiplier technology offers ultra-high capacity — up to 76.8Tb/s of data using 192 channels at 400G speeds per 75GHz channel — in a plug-and-play blade using C-band transponders.

The company said this 3X boost is particularly crucial for those applications where C-band transmission is the only available option for the foreseeable future, such as optical links that use direct-attach or transponder-attach ZR/ZR+ pluggable coherent optics.

The Fujitsu TransLambda Test Kit, which is currently being used in customer lab trials, is offered in a single blade configuration that can be used with any legacy WDM network architecture including multi-vendor systems.

“TransLambda technology is just the latest in a line of innovations from Fujitsu to achieve the highest network speed and capacity as cost-efficiently as possible, helping our customers gain true competitive advantage in today’s demanding marketplace,” said Paul Havala, vice president of global planning at Fujitsu Network Communications. “Our TransLambda fiber multiplier approach is a much more cost-efficient way to achieve significant capacity increases without installing L-band equipment, addressing cost and operational overhead while seamlessly integrating into existing network architecture to fully leverage deployed fiber assets.”
