Qualcomm Technologies has unveiled its next-generation modem purpose-built for Internet of Things (IoT) applications such as asset trackers, health monitors, security systems, smart city sensors and smart meters, as well as a range of wearable trackers.
The Qualcomm 9205 LTE modem brings together global multimode LTE category M1 (eMTC) and NB2 (NB-IoT) as well as 2G/E-GPRS connectivity, application processing, geolocation, hardware-based security and support for cloud services.
The modem is engineered to reduce power consumption by up to 70 percent in idle mode for battery-powered IoT devices that need to operate for 10 years or longer in the field. The Qualcomm 9205 LTE modem is also 50 percent smaller and more cost-effective than its predecessor – for IoT applications requiring low-power, wide-area connectivity in a small form factor device. The new modem is also software-compatible with the Company’s prior LTE IoT solutions, which allows module manufacturers to reuse software investments to develop new module solutions.
“The innovations included in the Qualcomm 9205 LTE modem are critical to support many of the 6 billion IoT devices expected to use low-power, wide-area connectivity by 2026,” said Vieri Vanghi, vice president, product management, Qualcomm Europe, Inc. “LTE IoT technologies are the foundation of how 5G will help connect the massive IoT, and we are making these technologies available to customers worldwide to help them build innovative solutions that can help transform industries and improve people’s lives.”
Global multimode LTE IoT modem and connectivity: Support for both 3GPP release 14 Category M1 and NB2 for operation with networks using any of these LTE IoT modes, as well as 2G/E-GPRS to allow for connectivity in areas where LTE IoT is not yet deployed. Category M1 mode also supports voice for applications such as monitored security panels, and mobility for applications such as asset trackers.
RF transceiver with fully integrated front-end: The Qualcomm 9205 LTE modem features an RF transceiver with extended bandwidth support from 450 MHz to 2100 MHz. It also integrates a comprehensive RF front-end, a commercial first in the cellular IoT space, which is designed to greatly simplify the design and certification of products using the new modem, and therefore accelerate time to commercialization.
Earlier this month, companies and vendors from across the wireless industry came together at Verizon’s facility in Irving, Texas to test 4G LTE technology over the CBRS (Citizen Band Radio Spectrum) spectrum. After the successful initial trials last year, Corning, Ericsson, Federated Wireless, Google, Nokia and Qualcomm Technologies are all collaborating in end-to-end system testing.
The CBRS band is made up of 150 MHz of 3.5 GHz shared spectrum, which until now has been primarily used by the federal government for radar systems. The FCC authorized shared use of the spectrum with wireless small cells in 2016. By using LTE Advanced technology, carrier aggregation and the spectrum access system (SAS), Verizon will be able to use this shared spectrum to add capacity to its network.
The end-to-end system tests are designed to accomplish several goals on the path to widespread commercial deployment:
Corning provided a SpiderCloud Enterprise RAN composed of a Services Node and SCRN-330 Radio Nodes. Ericsson’s Radio System solution is comprised of 4×4 MIMO, 4x20MHz Carrier Aggregation, including CBRS spectrum delivered over infrastructure aggregating Ericsson’s outdoor micro base station (Radio 2208 units) with the indoor B48 Radio Dot System in the same baseband (5216 units). Nokia provided FlexiZone Multiband Indoor BTS, FlexiZone Multiband Outdoor BTS and FlexiZone Controller.
In addition, participants in this ecosystem have set up private LTE sites which are using CBRS spectrum. Private LTE networks are being engineered to meet the needs of enterprise customers who want greater control over their LTE solutions including private on-site servers, control over access to their designated LTE network, as well as increased throughput and reduced latency through dedicated backhaul.
The end-to-end system testing, which began in February and will continue over the next several weeks, has provided actionable insights and have significantly advanced CBRS spectrum deployment feasibility.
“The promise of the CBRS band and enabling the use of wider swaths of spectrum will make a big impact on carrying wireless data in the future. These trials are critical to stress test the full system,” said Bill Stone, VP technology development and planning for Verizon. “There are many players in the CBRS ecosystem and these successful trials ensure all the various parts perform together as an end-to-end system for our customers’ benefit. We want to ensure devices efficiently use CBRS spectrum and that the new components effectively interact with the rest of the network.”
At the conclusion of this testing, equipment will be submitted for certification through the FCC. Following that deployment can then begin. Both commercial deployment of LTE on CBRS spectrum and devices that can access the CBRS spectrum are expected to begin in 2018.
CommScope, Ericsson Complete SAS Interoperability Testing for CBRS
To help ensure their readiness for commercial deployment in the CBRS wireless spectrum, CommScope and Ericsson have successfully completed interoperability testing of their equipment. The testing is one of the first successful interoperability tests using the Wireless Innovation Forum’s release 1.2 specifications.
“CommScope’s team of architects, developers and engineers have been building an industry-leading SAS for nearly two years,” said Tom Gravely, vice president of research and development, Network Solutions, CommScope. “Completion of interoperability testing with a major radio equipment provider such as Ericsson validates our SAS design and readies us for commercial deployment.”
The interoperability test confirmed that CommScope’s Spectrum Access System (SAS) and Ericsson’s radio infrastructure with CBRS spectrum support will work together as part of a CBRS network. The rigorous SAS–Citizens Broadband Radio Service Device (CBSD) interoperability testing used a battery of scenarios to verify that both products meet governmental requirements and industry protocols, as well as CommScope’s and Ericsson’s respective quality standards.
“Ericsson offers a comprehensive portfolio of CBRS network solutions that will help operators of all sizes deploy in this spectrum quickly and successfully,” said Paul Challoner, vice president of Network Product Solutions, Ericsson. “Additional milestones need to be reached for CBRS to become a reality, but we are pleased to complete interoperability testing with CommScope as part of the developmental process.”
In a CBRS network, a SAS and CBSD work together to ensure that the appropriate wireless signals are transmitted and received between the core network and end-user devices, while managing interference. An Environmental Sensing Capability (ESC) works with the SAS to identify the wireless signals of incumbent users to avoid interference from CBSDs. CommScope is one of four ESC operators conditionally approved by the FCC to provide SAS and ESC services.
Qualcomm Technologies, ZTE and China Mobile have achieved the world’s first end-to-end 5G NR Interoperability Data Testing (IoDT) system demonstrating a data connection based on 3GPP R15 standard. Following the guidelines of China Mobile, the IoDT connection demonstration took place at China Mobile’s 5G Joint Innovation Center, and utilized ZTE’s 5G NR pre-commercial base station and Qualcomm Technologies’ 5G NR sub-6 GHz UE prototype.
The end-to-end 5G NR system operates in the 3.5 GHz band and supports 100 MHz bandwidth, compliant with the 3GPP Release-15 5G New Radio layer 1 framework — including the scalable OFDM numerology, new advanced channel coding and modulation schemes, and the low-latency self-contained slot structure. The end-to-end 5G NR IoDT system is designed to efficiently achieve multi-gigabit per second peak data rates at significantly lower air interface latency than 4G networks.
“Implementation of 5G NR technologies will be critical to meeting the increasing connectivity requirements of emerging mobile broadband experiences such as streaming high-definition video and immersive virtual/augmented reality in the future, as well as enabling new high-reliability, low-latency services for autonomous vehicles, drones and industrial control, etc.,” said Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT
The successful interoperable connection of the end-to-end 5G NR IoDT system serves as an industry milestone toward pre-commercialization of 5G NR technologies at scale, driving rapid development of 3GPP standards-compliant networks and devices.
July 11, 2017 —
Verizon has successfully transmitted its first live Voice over LTE (VoLTE) call over its commercial Category M1 (Cat-M1) network with the help of Ericsson and Qualcomm Technologies, which is said to be an important moment in the evolution of IoT connectivity. Cat-M1 is a 3GPP-based technology that is designed to allow low-power Internet of Things devices to communicate over licensed spectrum
Cat-M1 can extend the reach of an IoT device across Verizon’s LTE network, whether it is a data-only or voice-enabled product.
In April of this year, Verizon launched the first nationwide commercial 4G LTE Cat-M1 network, which spans 2.4 million square miles, designed to provide scale, coverage and security for customers seeking wireless access solutions for IoT.
Verizon’s Cat-M1 network is built on a virtualized cloud environment, which enables IoT deployment and nationwide scaling. Cat-M1 is a new class of LTE chipset that is designed for sensors, which requires less power and supports an array of use cases ranging from water meters to asset trackers to consumer electronics.
The low bandwidth use cases for Cat-M1 chipsets demand new types of data plans, including low rate, multi-year plans to match the longer useful life of devices.
In 2016, Verizon launched a limited commercial Cat-M1 network.
