The main participants Qorvo, Yole and Keysight are paying attention to the leading and subversive radio frequency technology in this area.
Radio Frequency Recognition (RFID) technology pioneering Kevin Ashon should create an identification (IoT) this phrase is appropriate. Today, the Internet of Things has transcend RFID, which covers almost all kinds of unwanted sensors that connect the Physical world to the Internet.
The next wave of connection technologies (including 5G) include seemingly endless use cases and applications, from wearable devices to smart home. One of the largest impairments is the number and type of competition RF connection standards (Figure 1). The key trade-off between these standards is how many data and transmission distances need to be transmitted - all of which balanced with the battery life of the system.
Many authorities pointed out that the Internet of Things is not about "things", but about new service business. The service is the key driver of the Internet of Things, and the RF connection is implementing these services. Wireless and cellular networks will become an integral part of the connectivity equation.
"In terms of honeycomb networked standards, Cat M1 / NB1 has opened up a broad new market for honeycomb operators." Glen Riley, general manager of Qorvo Filter Solutions, explained in the nearest semi-Pacific Northwest Forum (Figure 2). LTE Cat M1 and NB1 are LTE versions developed by the Third Generation Partner Program (3GPP). CAT M1 / CAT NB1 For remote, low power consumption and data rate applications such as smart meters and asset tracking.
New mobile standards have taken approximately every 10 years, Clare pointed out Troadec, activities leaders, RF equipment and technology, Yoledéveloppement - Another host in Half Pacific NW Forum. The new standard has opened a new application area for end users. For example, the goal of emerging fifth generation mobile networks (or 5G) is to better implement IOT (Fig. 3) than a lower delay and lower battery consumption than 4G devices. Troadec points out that emerging 5G radio will be built on millimeter wave, new radio access network (RAN) and radio access technology (RAT).
Complete 5G implemented schedule also takes a few years. According to a recent report in Dell'oro Group, RAN revenue will be the lowest in 2017 to 2022. The initial 5G RAN will be deployed as a macro station, followed by a 5G city for urban environment. By 2021, millimeter waves will initially account for less than 5% of 5G market operators.
Destructive and enabled 5G
What is 5G key destructive technology trends? It depends on who you ask. In the nearest IEEE IMS 2017 event, the Keysight presentation lists the following key support technology:
- 5G new radio (NR) standard - separate from LTE. This is a 3GPP standard.
- SpecTre - Other 5G or "pre-5g" air interface specifications include:
Verizon PRE-5G specification (fixed wireless millimeter wave)
AT & T PRE-5G trial version (fixed wireless millimeter wave)
KT specification (mobile wireless millimeter wave)
- Millimeter wave and phase array antenna - complexity will require 20 dB baseline additional link budget (or 100 times power factor)
- Multi-input / Multi-Output (MIMO) - will significantly improve wireless data rates and link reliability.
- Wireless Access Network (RAN) and core network - how traditional and new 5G network architecture interact?
The list is closely related to the 5G subversive technology proposed by qorvo's Riley:
Millimeter spectrum
Large-scale MIMO
Advanced coding and modulation scheme (part of the 5G NR standard)
Integrated backhaul and cloud-based RAN
From a technical point of view, Riley points out that this will mean higher frequencies, broader bandwidth and higher efficiency power amplifiers (PAs). Other desired components will include low noise substrate LNA, quantify phase shifters, and ultra-low jitter clocks. It is also necessary to provide low-cost millimeter wave packages, ultra-high speed and low power A DC / D AC, high gain directional antenna and beamforming and high data rate serial links (such as SerDes, TIA, and optical drives).
Yole's Troadec confirms the importance of these components. The growth of the RF component market will be led by the filters and duplexers, accounting for 72% of the 2020 total market (see Figure 4).
Summarize
In short, the Internet of Things is actually related to the service. These services need to be connected to work. The latest cellular technology for the Internet of Things is 5G, which provides faster data, low delays, and high-capacity and bandwidth (4K video and cloud storage) for time-critical services such as automatic driving vehicles.
Semiconductors and Electronics must recognize key user case applications, services and standards are the main drive factors behind the Internet of Things and 5G technology.
