## 5 5G FWA Field Trials
### 5G FWA Field Trial Overview  
To start with, AT&T reveals its first U.S. 5G business customer trial in conjunction with Ericsson and Intel on 5 December 2016, in Texas. The presented public 5G demo includes real-time camera feeds and 4K HD video streaming with approximately 14 Gbps speeds [330]. Likewise, AT&T and Nokia, on 22 February 2017, publicized their collaboration on the innovative 5G technology that exploits the 39 GHz band. It was also stated that the 5G FWA tests had been carried out using the DIRECTV NOW, the AT&T Internet TV streaming service, and Nokia's AirScale radio access platform, at 39 GHz. The success of the test demonstrates the world's first viability for efficient service delivery at high frequencies [331]. Additionally, on 14 March 2017, AT&T affirmed that its standards-based mobile 5G services will be launched. It was stated that similar standards being employed for the non-standalone and standalone variants of the mobile 5G NR technology can also be implemented for the envisaged 5G FWA [332]. Moreover, AT&T, Ericsson, and Intel announced a 5G FWA trial based on mm-wave in Texas on 27 June 2017. Likewise, on 25 July 2017 [333], Samsung Electronics and Aroiva conducted Europe's first field trial in the UK in an attempt to demonstrate the strength of the 5G FWA broadband services. The trial is implemented on Samsung's 5G network solution and CPE. Furthermore, a 28 GHz mm-wave spectrum is exploited as well, on the Aroiva side. Note that 28 GHz is the standard band being employed for the 5G trials in countries such as South Korea, Japan, as well as the USA. In the UK, Aroiva owns the national license for it. The demonstrated end-to-end 5G FWA network was declared to be capable of supporting concurrent streaming of over 25 ultra-high-definition (UHD) 4K TV channels [247; 249; 259; 265; 334; 335; 336; 337; 338]. In addition, Samsung network solutions are expected to be employed by Verizon in the commercial 5G FWA launch. On 29 November 2017, Verizon declared its intention for commencing 5G FWA residential services that will be based on mm-wave spectrum and Ericsson equipment [254; 339]. Similarly, AT&T commenced its major 5G FWA trial in which mm-wave spectrum and 5G antenna prototypes are employed on 18 December 2017, also in Waco, Texas [254; 340]. In addition, Qualcomm, Verizon, and Novatel announced their intentions for collaboration on further trials, as well as wide-scale commercial deployment, which will primarily be focused on 5G NR based on 28 GHz and 39 GHz mm-wave spectrum bands operation [254; 341]. In a related development, Telus and Huawei have launched the first urban 28 GHz end-to-end 5G FWA trial on 14 February 2018, in Vancouver's 5G Living Lab'. The trial was as a result of their previous successful 5G 3 GPP mm-wave 'wireless-to-the-Premise' FWA pilot being performed on 23 June 2017 [254; 342]. Besides, a long-reach FWA connection has also been reported in [343; 324]. On 26 February 2018, T-Mobile announced its plan to build out 5G in 30 cities among which customers in Los Angeles, New York, Las Vegas, and Dallas are expected first to experience the services that would be deployed on its 600 MHz, 28 GHz, and 39 GHz frequencies [254; 344; 345]. The nationwide coverage is anticipated in 2020 and T-Mobile planned to merge with Sprint on the project [254; 346]. Moreover, the 5G network equipment roll-out had been confirmed. Nevertheless, T-Mobile wants 5G smartphones to be available before commercial services will be offered [254; 345]. Similarly, the University of Sussex conducted a practical 5G test in collaboration with Plum in July 2018. In the tests, different potential conditions in which 5G signals will be interacting with the environment objects such as buildings and trees are modeled. Despite the limiting conditions, about 100 times faster data speeds, compared with normal broadband solutions, were recorded. The test offered positive results for the FWA implementation [249].
