Hi. We just finished implementing Oracle's WMS using MC9090 and MC9190 handhelds, connecting to Aruba APs with internal antennas. We have had a lot of connectivity issues, which have been resolved for the most part. We need to extend this implementation to 2 other new warehouses, and I wanted to know your feedback on best practices, since we need to purchase everything from scratch. Are Motorola's handhelds designed to work better with Motorola APs? Should we better use Cisco, Ubiquiti, Aruba or any other brand? Do you recommend a specific external antenna to install on any of these APs? Is there another handheld that has a better wifi radio? All of your suggestions are greatly appreciated.
