Abstract: Embodiments are directed towards providing document change alerts in a cloud-based wireless network system. A list of a plurality of target radio frequency design sheets is obtained. One or more cloud-based folders is then search for the plurality of target radio frequency design sheets. One or more corresponding target radio frequency design sheets are identified during the search. A last-modified date of the corresponding target radio frequency design sheet is compared to a target date. In response to the last-modified date of the corresponding target radio frequency design sheet being more recent than the target date: a most recent version of the corresponding target radio frequency design sheet is maintained and an older version of the corresponding target radio frequency design sheet is archived. A modification notification is then sent to at least one user associated with the corresponding target radio frequency design sheet that changed.

A user generates an electronic shopping cart based on interacting with a merchant website using a first device. In response to receiving a request for transferring the electronic shopping cart, cart data associated with the electronic shopping cart is obtained.

The code is presented on the first device. In response to receiving the code from the second device, the electronic shopping cart is re-generated based on the cart data extracted from the code. The electronic shopping cart is made accessible to the user via the second device.
