QCOM vs T Comparison

Qualcomm develops and licenses wireless technology and designs chips for smartphones. The company's key patents revolve around CDMA and OFDMA technologies, which are standards in wireless communications that are the backbone of all 3G, 4G, and 5G networks. Qualcomm's IP is licensed by virtually all wireless device makers. The firm is also the world's largest wireless chip vendor, supplying nearly every premier handset maker with leading-edge processors. Qualcomm also sells RF-front end modules into smartphones, as well as chips into automotive and Internet of Things markets.

The wireless business contributes about two thirds of AT&T's revenue. The firm is the third-largest US wireless carrier, connecting 72 million postpaid and 17 million prepaid phone customers. Fixed-line enterprise services, which account for about 16% of revenue, include internet access, private networking, security, voice, and wholesale network capacity. Residential fixed-line services, about 11% of revenue, primarily consist of broadband internet access, serving 14 million customers. AT&T also has a sizable presence in Mexico, with 22 million customers, but this business only accounts for 3% of revenue. The firm still holds a 70% equity stake in satellite television provider DirecTV but does not consolidate this business in its financial statements.
