Wireless Telecommunications FCC
Cellular and PCS phones, pagers and two-way radios, radio spectrum.
Federal Communications Commission - FCC
"The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. (United States). "
Geographic Information Systems - FCC
"With these data sets, you will be able to determine the locations and limited technical details of existing towers the FCC collects data on (i.e. Cellular, Paging, Microwave, AM, FM, etc...). This information can be extremely helpful in conducting analysis such as; current service deployment, need/feasibility determinations of new services, co-location of antenna structures, inventorying of structures, network planning, etc..."

Bluetooth Technology - Uniting the Devices
"The Bluetooth Special Interest Group (SIG) is formed with five companies." 1998 AD
On your phone - With Bluetooth technology your phone can do more than you realize.
"Bluetooth technology also uses radio waves. The biggest difference between Bluetooth technology and devices like FM radios and TV is distance. Radios and TV are meant to broadcast to many people over miles or kilometers. Bluetooth technology sends information within your own personal space, which is called your..."

Modbus Communication Protocol Suite
Some Activities of the Modbus Organization are ...to Encourage, support and evolve ...
- Participation in standards activities worldwide.
- Leading the evolution of the Modbus protocol and its variants.
- Modbus across a broad spectrum of physical layers and transmission media.
- Conformance testing program to insure greater interoperability of Modbus devices.
Modbus Protocol is a messaging structure developed by Modicon (Schneider Electric) in 1979. It is used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment.
The semiconductor industry has implemented a Network Communication Standard and an Object Messaging Protocol using Modbus TCP/IP. This allows SEMI Sensor Bus compatible sensors to communicate with each other using Modbus TCP/IP.
Spinwave Systems’ Wireless Thermostat Controller is a drop-in replacement for almost any existing conventional non-communicating thermostat, re-using the existing equipment wiring. Thermostat functions and values are accessible remotely through an embedded web page of the Modbus Mesh Gateway or via Modbus communication.
Wireless Thermostat Controller, SWC-TSTAT-1
The wireless thermostat controller is a full function wireless mesh device with integrated radio that can be configured to control heat pump systems, (with auxiliary or emergency heating if necessary), gas/oil heating systems with add on cooling, control high and low balance points as well as the number of heating and cooling stages needing precise control. It can even adapt to manage the number of fan speeds it must control.

PICMG is a consortium of companies who collaboratively develop open specifications for high performance telecommunications and industrial computing applications.
Specs and Standards for Advanced Mezzanine Card, AdvancedTCA, COM Express, CompactPCI, e-PCI-X, MicroTCA and others.

"The PCI-ISA passive backplane standard moves all of the components normally located on the motherboard to a single plug-in card. Looking much like a standard ISA or PCI card, a PCI-ISA CPU card has two edge connectors on it - one for the PCI bus and one for the ISA bus. The "motherboard" is replaced with a simple "passive backplane" that has only connectors soldered to it."
