Back in October, when Qualcomm (QCOM) said it would purchase CSR, the company that was an initial champion of the now-popular Bluetooth technology found inside headsets, speakers and phones, it was seen as an obvious technology bolt-on acquisition. The addition of CSR would pair with Qualcomm’s interest in the internet of things and its $3.1 billion purchase of Wi-Fi chipmaker Atheros back in 2011. That’s still true today, but since the deal has been announced Jana Capital has taken a significant stake in Qualcomm and pressured the company to make changes. Last month it said it planned to lay off 15% of its workforce and said it would only focus on five businesses: mobile phones, the internet of things, data centers, small cells, and automotive.

Qualcomm also has the unenviable task of becoming a chip firm that has to adapt from having a relatively small and captive customer base to one serving a huge number of customers across many verticals. It also doesn’t have a radio technology or a limited number of competitors to lock customers in when it’s selling its Wi-Fi products, and soon its Bluetooth chips. In interviews with Fortune, Qualcomm and CSR executives explained how this deal will help Qualcomm handle some of these challenges both technically and strategically.

With CSR Qualcomm isn’t simply buying a radio chip firm as it did with Atheros. It’s also buying a company that makes an entire package of chips and software that fits into cars, headsets, and Bluetooth speakers, which dovetails nicely with Qualcomm’s own design philosophy of squeezing the brains of a smartphone into the same package with the radios and the graphics core. This integrated single-package approach lowers the cost of materials, saves on space, and tends to save on battery life. That’s essential for cell phones and the chips powering your Bluetooth headset.

CSR is also the keeper of some fancy software that turns Bluetooth radios, which are usually point-to-point radios, into a mesh network designed for the smart home or office. This CSRMesh technology is part of several big lighting products expected out in the fall, and parts of it will undoubtedly make it into the next generation of the Bluetooth standard.

Anthony Murray, formerly a senior vice president with CSR and now the senior vice president and general manager of IoE (Internet of Everything) at Qualcomm, explained that not only could we see the CSRMesh technology in Bluetooth, but one day we may even see Qualcomm supporting the Thread protocol created by Samsung, Nest and other big names in home automation on top of the Bluetooth radio.

“So far the Thread protocol has chosen to support one radio [ZigBee], but there are many of radios out there that it could support and there are advantages in using the Bluetooth radio in some use cases,” Murray said. “We can’t not support Thread given the strength of the supporters behind it.”

Qualcomm will also get a few esoteric technology holdings, such as a document imaging software business that may eventually be spun out, but for the most part CSR’s silicon and software will boost Qualcomm’s internet of things and automotive businesses easily. It also helps bring Qualcomm another set of managers who are used to selling to a wide range of customers and a more traditional customer base. Qualcomm historically sold radios based on technology it developed, which meant that once it convinced a network operator, such as Verizon, to buy into a technology, any company that wanted to sell a handset to that network operator had to license that radio technology from Qualcomm.

In many cases they bought the radio from Qualcomm too. As Qualcomm grew it developed the brains behind smartphones as well and integrated that tech with radios, which meant its customers were still the handset makers. Qualcomm grew along with the smartphone market, providing some of the most powerful application processors inside handsets. For the most part, it was the Intel of smartphones, with the exception of the iPhone once Apple decided to build its own chip.

However, competition from China’s Mediatek was looming, and Qualcomm stumbled last year with one of its designs. It lost Samsung, which is still affecting its earnings. With these challenges in mind, diversifying its customer base isn’t a bad idea. Raj Talluri, senior vice president of product management, said Qualcomm brought in $1 billion from the internet of things in 2014 and expects to bring in 1.6 billion in 2015.

He said much of that comes from adding connectivity to existing devices, especially as a way to future proof them even if the manufacturer isn’t sure how they want to use it. “China is the most advanced and we see a lot of white goods with connectivity,” he said. “There are so many rice cookers that are shipping with connectivity in them.”

As for structuring Qualcomm to sell chips for thousands of different devices, from rice cookers to drones, as opposed to making a few different lines of chips for mobile phones, Talluri is optimistic that the San Diego-based company will rise to the challenge.

“That’s how most semiconductor companies are,” he said. “It’s a model that we know how to set up and CSR is one such company. The idea is you have multiple people each responsible for a segment and pick the technologies that they need … and you build the distribution channels and let the machine start rolling.”

He admits it may not be as “exciting” as winning or losing a chip inside a handset, but it is a far more stable business and as a veteran of Texas Instruments he’s been there before. First with Atheros and now with CSR, Qualcomm is adapting to what may be a far less exciting path, but one that could provide greater diversity and stability.
