EXECUTIVE SUMMARYPDF

The 3GPP's standards for Long Term Evolution (LTE) Release 13 (frozen) and 14 (nearing completion) are associated with the term LTE-Advanced Pro (LTE-A Pro). Vendors building the many Release 13 and 14 features into their solutions, and operators deploying them in their networks, can apply this term in their marketing. But as with previous milestones in network technology, what is meant to clarify sometimes has the opposite effect.

While one of the key attributes of LTE-A Pro networks is faster speeds for users, this is reliant on suitably capable devices – and these are currently not available. "Gigabit LTE" is the current state of the art in commercial networks.

2017 will be the year of LTE-A Pro – although vendors might not describe it quite like that. While the focus of the mobile industry will be firmly on 5G, numerous technology paths are being followed by operators that will involve the deployment of 3GPP Release 13 features this year.

Carrier aggregation will continue to be used throughout 2017, in a variety of bands and modes. True multi-Gigabit LTE networks that really meet the LTE-A Pro targets of >3 Gbit/s throughput in the downlink are a couple more years into the future, however; by then, some of those will be "5G," using pre-standard Release 15 features.

LTE-Advanced Pro: Deployment Progress reviews the state of LTE-A Pro technology development and deployment. It highlights the key networking features encapsulated by LTE-A Pro, and shows how far vendors and operators have got in terms of developing, trialing and, in some cases, deploying the technologies. It also profiles leading vendors of mobile RAN systems, as well as a leading LTE-A Pro chipset vendor, showing how far along they are with implementing Release 13 standards in their technologies, how they are differentiating their approaches to LTE development in advance of the advent of 5G and how far they have come in terms of trialing and deploying the Release 13 networking features.

COMPANIES COVERED

Key characteristics of LTE-A Pro networks are that they should be able to deliver peak throughput in excess of 3 Gbit/s (compared with in excess of 1 Gbit/s for LTE-A networks), and should exhibit latencies lower than 2 ms (compared with latencies lower than 10 ms for LTE-A networks). The following excerpt lists some of the key features that are enshrined in 3GPP Release 13 (and set to be enshrined in Release 14). They represent just a subset of many features and specifications covered by the two releases.

LTE-Advanced Pro: Deployment Progress is published in PDF format.

LTE-Advanced Pro: Creeping Into Networks Near You

While the 3GPP has designated all things from Releases 13 and 14 of its standards as Long Term Evolution-Advanced Pro (LTE-A Pro), the term does not seem to have excited industry marketeers. It is not as catchy as LTE-A, it is not as advanced as 5G and it is not easy to understand conceptually, as the features covered by Release 13 and (soon) Release 14 cover a variety of types of service and technology improvements.

Industry players are more interested in pushing their Gigabit LTE (which, make no mistake, is a big advance for the industry) or promoting their "nearly 5G" and Internet of Things (IoT) solutions. Where new network features are being introduced (for instance, 64 QAM in the uplink or License Assisted Access, LAA) these are either bundled up in operator and vendor announcements about next-generation network improvements or discussed in their own right without reference to LTE-A Pro.

But this does not mean nothing is happening. On the contrary, vendors and operators have been involved in dozens of field and commercial trials of technologies that will have a big impact on service delivery, such as LAA, aggregation of more than five carriers, new modulation techniques, improved beamforming and multiple input multiple output (MIMO) techniques and new IoT networks. Some commercial services have also begun to appear. The IoT standards enshrined in Release 13 (NB-IoT and LTE Cat-M1) are now both being deployed in live networks; a handful are now operational and many more are on the way. Selected operators have begun to introduce the technologies to enable advanced mobile broadband. The current state of the art is around 1Gbit/s downstream, but this will improve further as new end-user devices become available with the capability to cope with higher download and upload speeds.

2017 will be the year of LTE-A Pro. We expect many live network deployments of both IoT and advanced broadband technologies this year as vendors race to migrate their operator customers toward 5G and as operators both strive to stay one step ahead of their rivals in terms of the headline speeds they can promise to customers and strive to open up new enterprise and public sector market opportunities.

Heavy Reading's latest report, "LTE-Advanced Pro: Deployment Progress," reviews the state of LTE-A Pro technology development and deployment. It highlights the key networking features encapsulated by LTE-A Pro, and shows how far vendors and operators have got in terms of developing, trialing and, in some cases, deploying the technologies. It also profiles leading vendors, showing how far along they are with implementing Release 13 standard features in their technologies.
