The 5G wireless revolution will come, if your city council doesn’t block it first

The excitement around 5G is palpable at the Brooklyn 5G Summit this week, and for good reason. Once the province of academic engineers, there is increasingly a consensus emerging among technology leaders that millimeter-wave technology is ready for prime time.
Yet there remain large barriers to a successful rollout, particularly at the local government level. Those challenges could prevent the U.S. from aggressively competing with other nations like China, which are investing massive resources to lead this next generation of wireless technology.
The Summit, now in its fifth year and organized by NYU Wireless, Nokia and IEEE, is designed to showcase New York’s technology leadership in the space. New York has been at the forefront of wireless for many years, with the first mobile phone call taking place in Midtown Manhattan.
That was 45 years ago though. This month, New York learned that it had been selected as one of two initial sites for a 5G testbed by the Platforms for Advanced Wireless Research program, which is managed by the National Science Foundation in concert with a consortium of wireless companies.
Through a program called COSMOS, researchers will deploy a total of 249 large, medium and mostly small cell nodes to West Harlem (including Columbia University’s Morningside Heights main campus) in order to investigate the performance of 5G in an urban setting. New York was awarded an initial grant of $3.6 million to execute the initiative.
This sort of testbed model is quite progressive in the wireless industry. While the notion of a minimum viable product and constant test feedback is a hallmark of software startups, that mentality has not been translated well into the wireless world. The hope for this testbed is that as new equipment is invented in the coming years, the West Harlem network can be continuously upgraded, serving as a model for potential deployments onto operators’ networks across the country.
It’s also critical because the network architecture of wireless is expected to change drastically in the years ahead. More computing will be done at the “edge” in order to reduce network latency and power the internet of things. In order to handle that traffic, new machine learning algorithms are going to have to be deployed that can actively manage traffic and ensure that applications have reliable performance. A realistic testbed provides key training data and analytics that can improve those algorithms and ultimately deliver better services to customers.
The good news is that the U.S. has conceived and launched this test program. The bad news is that we may still be too slow to win the competition for this generation of wireless tech.
The wireless industry’s trade association, the CTIA, has declared the rollout of 5G a “race” between the United States and the Asian nations of China, Korea and Japan. The U.S. widely won the competition for 4G technologies, but the rise of Huawei as a dominant force in the wireless equipment space means that competition for technological leadership has never been more keen.
The White House and the federal government have made a 5G rollout a national security priority, but getting 5G wireless into the hands of consumers is likely to be stymied by opposition from local city councils and mayors around the issue of site access.
In order to provide reliable cell service, operators need to deploy cell sites near consumers. While they don’t need direct line of sight for the spectrum used in 4G, buildings and other objects can interfere with signals, making it critical to have a dense mesh of sites in urban environments.
