5G is here and ready to deliver multigigabit speeds and ultralow latency. Enterprise organizations are eager to leverage 5G to reap its benefits and opportunities for innovation.
Telit’s Marco Contento and Joe Braga have answered the top questions about preparing for a 5G future, including how to do automation testing, what to expect for machine-to-machine (M2M) services in 5G, how 5G will be used for remote devices, and more.

Marco Contento: There isn’t a straightforward answer. It depends on the use case or application the industry wants to approach. Most of the use cases can be well served by sub-6 GHz bands. mmWave is more suitable for fixed wireless access (FWA) applications such as outdoor customer premises equipment (CPE). There are also potential use cases in which mmWave might be used where high throughput is required in downlink and uplink, such as streaming high-definition video outdoors or indoors.
Joe Braga: Telit has evolved all its offerings from over 20 years of servicing the most demanding verticals and industries with quality as the primary focus. It has been a significant component of the Telit brand promise all this time. For example, all our modules meet the most stringent industrial quality standards. They include a full -40° C to +85° C operating temperature range with minimal roll-off at the edges and best-in-class RF performance. For example, we offer the only module Gigabit LTE in the market with dual-uplink RF chains to ensure full uplink speed performance even when carrier aggregation must occur in different bands. On the service side, all Telit operation infrastructure elements are designed with redundancies and constantly updated with security features from industry-leading partners like Sternum, AWS and others.

Marco Contento: M2M services will continue to be served by LTE-M and NB-IoT for a long time, thus by the 4G/LTE networks. Mobile network operators (MNOs) are currently focused on bringing 5G New Radio (NR) for mobile broadband (MBB) use cases. We’ll have to wait a few years before seeing chipset and low-tier IoT devices supporting 5G NR, as well as the infrastructure and MNOs.
Marco Contento: As for all the cellular devices, different types of tests are required, which are mainly:
For each above, different test equipment is used, and various types of automation are required. Known brands in the industry provide the test equipment.
Joe Braga: 5G is well on its way to becoming part of widely deployed devices like healthcare trackers, surveillance systems and smart city services, to name a few. NB-IoT and LTE-M will continue evolving in 5G networks with dynamic spectrum sharing, dual-mode 5G Cloud Core and standardization commitments by the 3GPP, even if COVID-19 delays schedules. With dynamic spectrum sharing, NB-IoT and 5G can co-exist with hardly any network efficiency compromise.
Joe Braga: Device management is absolutely an integral part of the 5G architecture. In 2020 Telit collaborated with Orange, workgroups and committees at OMA SpecWorks to produce the paper titled “OMA Lightweight M2M (LwM2M) – Ready for 5G.” From it, you can glean the direction and reach of remote device management afforded by the evolution of the LwM2M standard inside 5G. As for costs, NR does much better at utilizing spectrum to accommodate narrowband standards, which will succeed LTE-M and NB-IoT. However, as stated in Question 5, it will be a few more years until we see LPWA-NR modules in the market. Until then, LTE-M and NB-IoT will continue growing, and prices will be dropping, including in India.
Marco Contento: 5G service in the U.K. is already available commercially through operators EE, O2, Three and Vodafone. They are each rolling out 5G coverage; thus, coverage and capacity will improve as time passes.
Marco Contento: We chose M.2 for two reasons:
Marco Contento: Neither is part of the 5G standard, but 5G is a significant enabler for both technologies. A fundamental ingredient of AI is a high-performing medium to network computing, sensing and storage nodes in the AI architecture, and 5G, with its high bandwidth and low latencies, is that medium in many ways. As 5G is quickly replacing cabling as the wireless connects autonomous robots, x-ray quality inspection cameras and more, we will see AI applied abundantly in manufacturing automation. Likewise, blockchain is bound to accelerate, considering it’s an archetype of decentralization, consensus-driven schemas and cryptography, all of which are essential for the IoT. Massive IoT started with LTE-M and NB-IoT and is fully supported in 5G with dynamic spectrum sharing and the 5G Evolved Packet Core (EPC) and 5GC dual-mode Cloud Core.
Marco Contento: North America, South Korea and Japan have already started to deploy mmWave mainly for consumer devices or to serve FWA use cases. Several other countries and carriers are also investing or deploying mmWave.
