The momentum round non-terrestrial networks (NTN) continues to construct, with each Keysight Applied sciences and Viavi Options this week asserting 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 take a look at software as a way to allow a tool underneath take a look at (DUT) to determine an NTN knowledge name connection by emulating cell 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 Take a look at Group, stated that the collaboration and profitable verifications “[deliver] essential milestones on the highway to business NTN service deployments. This early verification accelerates the trade’s transfer to the certification stage and business deployment.”
Viavi, in the meantime, launched a brand new system for testing of NTN, together with excessive altitude platforms (HAPS). The corporate’s TeraVM resolution stands in for the community core, whereas its TM500 emulates the varied features of a non-terrestrial deployment as a way to validate base stations: Excessive machine quantity, new mobility patterns, sign propagation delays, and “different circumstances distinctive to NTN.” Viavi stated that its resolution offers take a look at situations which are “ideally suited for early useful exams corresponding to 3GPP protocol testing and might 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 stated in a launch, describing the complexity of the testing that should occur. “NTNs should be dependable to deal with the gap, pace and mobility of each satellite tv for pc, HAPs and Person Gear (UE), whereas nonetheless delivering on efficiency. Take a look at options should not solely required to emulate completely different UE mobility and fading profiles, however they need to additionally take the big doppler shifts from fast-moving satellites and airborne platforms into consideration.”
“NTNs provide new alternatives and partnerships for cell and satellite tv for pc operators and the thrilling potential to supply connectivity to each underserved and over-populated areas in addition to assist mission-critical purposes,” stated Ian Langley, SVP of Viavi’s wi-fi enterprise unit. “Nonetheless, amidst the rising curiosity and race to deploy these networks, it’s important that reliability, stability, and efficiency testing are performed to make sure success.”
In different take a look at information:
-ICYMI: Keysight additionally reported its outcomes for the newest quarter, which counsel that the slowdown in 5G community funding could also be trickling by to check firms. Full story right here.
-Market evaluation agency TechNavio expects that the marketplace for gigabit Ethernet take a look at tools will see a compound annual progress price of neraly 8% by 2027, reaching greater than $802 million by the top of the forecast interval. Development in knowledge visitors and demand for high-speed Ethernet as nicely rising numbers of information facilities are elements driving the market.
–Tektronix has launched the latest model of its Keithley KickStart Software program, which incorporates enhancements to its battery simulation software. That simulator app allows customers to “simply generate battery fashions, simulate batteries, and carry out battery cycle exams for shopper wi-fi IoT units, automotive, and industrial purposes,” the corporate stated, 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 purpose to make the providing a “‘one-box’, no code” resolution.
-Who’s tops within the Canadian market when it comes to consumer expertise? Opensignal launched evaluation this week, with Rogers a standout. Extra particulars in this story.
-On the large-scale proving floor for numerous tech, IoT and sensible metropolis purposes within the metropolis of Peachtree Corners, Georgia, new autonomous supply robots are being examined on the roads. These robots, from Clevon, are operating on T-Cellular US’ 5G community and Clevon is becoming a member of the Curiosity Lab ecosystem. These robots are designed to “acquire orders at warehouses, retail shops, darkish shops and micro achievement facilities, after which ship these items to individuals and companies across the metropolis,” based on Clevon.
