Microsoft Corp. and Amazon.com Inc. are trying to expand their wireless Internet business to include tablets and phones.
The two companies announced Friday they have entered a deal that will allow them to make wireless routers that can deliver Internet service to each other.
The deal is the latest sign that Microsoft and Amazon are looking to tap into new markets.
Microsoft and Amazon have been at odds for years.
In January, Microsoft sued Apple Inc. for selling smartphones without Microsoft’s software.
In October, Amazon sued Microsoft for not delivering Windows Phone software.
Microsoft won the lawsuit, and a jury in Seattle agreed.
The companies also had a long-running dispute over Microsoft’s cloud-computing business, with Microsoft suing Google Inc. in 2016 for taking over Google’s Google Cloud Platform.
Microsoft argued that Google’s cloud computing was a threat to its Windows Azure platform, which runs on Microsoft’s servers.
