Ericsson, they had or still has the best stuff. But just like any big companies, management likes to kill the company for their own good. Early 2010s when Huawei becomes a threat to their business ( that was before Huawei was even known by general public ), stocks and earning were down, they finally woke up.

But today they are still much more expensive than Huawei, AND their bet on Intel 10nm Custom Foundry didn't help.

Again, blame Intel.
