Radio (wireless, robotic) options

There are many radio (wireless) standards that are integrated into or used with our rugged handheld computer products. Listed below are common names for those standards and the radio transmission (broadcast) frequencies they have previously or currently use (at least in the United States for non-global systems).

 

 

 

Since most of these separate radio standard types usually operate on different frequencies and some use automatic channel / signal / frequency hopping (spread spectrum), most often few conflicts are encountered when using these radios simultaneously in close proximity. Though having each transceiver, transmitter, and/or receiver with antenna enabled in close proximity to each other has the potential to cause signal attenuation, possibly leading to reduction in the signal strength and range of each radio.

 

Extended Range Bluetooth

 

Some adapter devices offer Class 1 Bluetooth specifically but with additional extended range, often advertised at 1000 feet (about 300 meters) or more. Some such adapters are listed below.

 

 

Extended Range Wifi 802.11

 

Some longer range Wifi 802.11b/g adapters that have been and/or are being used with our rugged handheld computer products, sometimes even in place of a built-in option, are described at the following website.

Non-Standard Protocol Radio Modems

 

A few other non-standard, custom radio devices (which most often utilize the worldwide 2.4 GHz ISM (Industrial, Scientific and Medical devices) band) which have been and in some cases still are being used with or integrated into our rugged handheld computer products include those from the following manufacturers and websites.

 

 

 

Some radio adapters which are often used to wirelessly connect devices such as data loggers, printers, total stations, weigh scales, digital calipers, and others that do not have built-in radio options include those described at the following web pages.
