Serial To Wireless
If you need to provide wireless access to a great deal of people in your business from one network, you will need to choose a serial to wireless product designed to make industrial devices accessible directly from the wireless network. Such a product will eliminate physical wires and provide benefits such as mobility, flexibility, wider coverage and lower networking costs. You can get this type of coverage for short distances or for very long distances. With Bluetooth, you can only cover a short distance, but it is very reliable, energy efficient and convenient wireless for short distances. You can get 802.11 a/b/g (WiFi) systems for greater distances (up to three hundred feet) such as the systems that people use in coffee shops, bookstores and libraries. For the greatest distance (up to forty miles) you would use a 900 MHz serial to wireless system.
