The backhaul segment of the network is traditionally made up of the intermediate point-to-point links between the core (or backbone) network and the small subnetworks at the network edge, where the base stations are. Since 5G is aiming for multi-Gbps data rates for subscribers, all this data will need to be backhauled at much higher rates, too.
Several package types can be used at mmWave frequencies, so the choice will depend on the specific application. However, some general design rules apply to all forms of packaging.

Knowles Precision Devices (DLI) offers filter technology that addresses the challenge of implementing high-performance filters at mmWave frequencies. Their 26 GHz, 28 GHz, and 39 GHz filter solutions deliver 3 GHz of bandwidth, greater than 50 dB rejection, and are 20x smaller than current alternatives while implemented in surface mount packages for standard tune-free assembly. They are capable of stable operation within the -55°C to +125°C temperature range. Custom design services are available.
Fixed Wireless Access (FWA) is one of the early planned use cases for 5G deployment, offering a new wireless alternative for providing broadband to homes and businesses. Because this requires very high bandwidth, many solutions for FWA consider use of new millimeter wave bands. This poses challenges for coverage, including increased path loss, weaker penetration through walls into the interiors of structures, and greater effects from shadowing of structures and trees on the outdoor propagation.
With a tremendous increase in the number of connected devices and mobile data demand predicted over the next decade, the wireless communications industry is exploring new technologies to accommodate 5G wireless data systems, including MIMO (multiple-input, multiple-output) technology and millimeter wave frequency bands. One of the more complex environments for these technologies are urban small cells, where the prevalence of multipath and non-line-of-sight conditions leads to many challenges, particularly at higher frequencies.

With the next big step in mobile communication, 5G will introduce new RF techniques, new frequencies and signal bandwidths. Ultimately, 5G New Radio (5G NR) will bring higher speed, reduced latency, more capacity and improved reliability. While the system parameters will change, the hardware to enable the new major step in mobile technology towards 5G NR will be different as well. New technologies will be deployed and designs have to follow the new requirements.

Current trends in smartphone industrial design and RF requirements mean that smartphones must fit more antennas into less space and/or increase the bandwidth of existing antennas. This article introduces four key elements to understand about antenna tuning in 4G and 5G mobile devices.
As 5G NR networks are deployed, live network testing is needed to ensure network coverage and Quality of Experience (QoE). In addition, QoE testing in 5G NR will get more complicated due to changes in the network architecture. This means traditional testing will not reflect the true service quality as seen by an application. QoE field testing will need to be tested at the application layer to address the 5G NR QoE measurement challenge and translate the user experience into measurable KPIs.
