The momentum round non-terrestrial networks (NTN) continues to construct, with each Keysight Applied sciences and Viavi Options this week saying NTN-related developments.
Keysight and MediaTek joined as much as confirm that MediaTek’s 5G modem know-how helps 5G New Radio and web of issues (IoT) applied sciences based mostly on 3GPP Launch 17 requirements for non-terrestrial networks (NTN). MediaTek is utilizing Keysight’s S8711A UXM 5G check utility as a way to allow a tool below check (DUT) to determine an NTN information name connection by emulating cellular networks for 5G NR and IoT. In the meantime, Keysight’s S8820A PropSim FS16 channel emulationtToolset emulates satellite tv for pc orbits and their results on the RF channel and air interface—primarily, “radio frequency digital twins,” as Keysight put it.
Peng Cao, VP and GM for Keysight’s Wi-fi Check Group, mentioned that the collaboration and profitable verifications “[deliver] necessary milestones on the street to industrial NTN service deployments. This early verification accelerates the trade’s transfer to the certification stage and industrial deployment.”
Viavi, in the meantime, launched a brand new system for testing of NTN, together with excessive altitude platforms (HAPS). The corporate’s TeraVM answer stands in for the community core, whereas its TM500 emulates the varied elements of a non-terrestrial deployment as a way to validate base stations: Excessive system quantity, new mobility patterns, sign propagation delays, and “different situations distinctive to NTN.” Viavi mentioned that its answer supplies check situations which can be “supreme for early practical checks similar to 3GPP protocol testing and may be utilized to each regenerative and clear architectures,” with further situations targeted on end-to-end testing and optimization in addition to validating community efficiency and reliability.
“Satellite tv for pc communication in 5G brings one other stage of complexity for testing,” Viavi mentioned in a launch, describing the complexity of the testing that should occur. “NTNs must be dependable to deal with the space, pace and mobility of each satellite tv for pc, HAPs and Person Tools (UE), whereas nonetheless delivering on efficiency. Check options aren’t solely required to emulate totally different UE mobility and fading profiles, however they need to additionally take the massive doppler shifts from fast-moving satellites and airborne platforms into consideration.”
“NTNs provide new alternatives and partnerships for cellular and satellite tv for pc operators and the thrilling potential to supply connectivity to each underserved and over-populated areas in addition to help mission-critical functions,” mentioned Ian Langley, SVP of Viavi’s wi-fi enterprise unit. “Nevertheless, amidst the rising curiosity and race to deploy these networks, it’s very important that reliability, stability, and efficiency testing are carried out to make sure success.”
In different check information:
-ICYMI: Keysight additionally reported its outcomes for the latest quarter, which recommend that the slowdown in 5G community funding could also be trickling via to check firms. Full story right here.
-Market evaluation agency TechNavio expects that the marketplace for gigabit Ethernet check tools will see a compound annual progress fee of neraly 8% via 2027, reaching greater than $802 million by the tip of the forecast interval. Progress in information visitors and demand for high-speed Ethernet as effectively growing numbers of knowledge facilities are elements driving the market.
–Tektronix has launched the most recent model of its Keithley KickStart Software program, which incorporates enhancements to its battery simulation utility. That simulator app permits customers to “simply generate battery fashions, simulate batteries, and carry out battery cycle checks for shopper wi-fi IoT gadgets, automotive, and industrial functions,” the corporate mentioned, and the brand new enhancements imply that customers don’t want further, separate options that create a battery mannequin and battery simulator—a part of Tek’s goal to make the providing a “‘one-box’, no code” answer.
-Who’s tops within the Canadian market when it comes to person expertise? Opensignal launched evaluation this week, with Rogers a standout. Extra particulars in this story.
-On the large-scale proving floor for varied tech, IoT and sensible metropolis functions within the metropolis of Peachtree Corners, Georgia, new autonomous supply robots are being examined on the roads. These robots, from Clevon, are working on T-Cellular US’ 5G community and Clevon is becoming a member of the Curiosity Lab ecosystem. These robots are designed to “accumulate orders at warehouses, retail shops, darkish shops and micro success facilities, after which ship these items to folks and companies across the metropolis,” based on Clevon.
