There are too many posts on this board expressing animosity between the wireless and wireline sides of the business. If you’re contributing to this animosity, you should stop! It’s silly! I’ll explain why below.
One recurring theme is that wireless couldn’t survive without wireline. Way back when, all wireless operators used T-1s and DS-3s and that generated quite a bit of revenue for the LECs. As capacity needs increased, they shifted to fiber about 20 years ago. There are a lot of fiber providers so wireless is no longer dependent on wireline but getting fiber from your own company is better for the balance sheet. Would you rather we paid AT&T for fiber?
It’s also true that wireless was initially financed by wireline but so what? Wireline saw an opportunity and they took it. T-Mobile was financed by investors outside of wireline and they’re doing just fine.
In short, wireless would do just fine without wireline and wireline would do fine without wireless but they are better together because there are significant synergies including bundling services. So stop this silliness! There’s enough drama and nonsense in the company and you don’t need to add to that.
