Microchip PIC - Wireless Connectivity Design
Ethernet. TCP/IP, ZigBee, MiWi - "The emerging standard for flexible wireless networking specifically designed for embedded control. ZigBee supports stars, clusters and mesh networks of up to 64k nodes. Microchip supplies a free stack that supports a variety of transceivers."
MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module.
Has a integrated PCB antenna, matching circuitry, and supports ZigBee too. Connects to many PICs via a 4-wire SPI interface. You can design wireless sensor networks and home automation systems.
The MRF24J40 is an IEEE 802.15.4 Standard compliant 2.4 GHz RF transceiver. It integrates the PHY and MAC functionality in a single chip solution.
A frequency synthesizer is clocked by an external 20 MHz crystal and generates a 2.4 GHz RF frequency. The receiver is a low-IF architecture consisting of a Low Noise Amplifier (LNA), down conversion mixers, polyphase channel filters and baseband limiting amplifiers with a Receiver Signal Strength Indicator (RSSI).

"Digi provides the essential layer of machine-to-machine (M2M) communications — the remote monitoring and management that critical applications depend on."
Digi - Wireless Device Networking
External and embedded Wi-Fi products make it easy to add embedded 802.11a/b/g wireless LAN networking to any electronic device, or to connect serial devices over a Wi-Fi network.
The XBee Wi-Fi Cloud Kit includes all of the hardware and software tools needed to build a cloud-connected Wi-Fi prototype in under an hour. The Internet of Things has never been so simple!
XBee Wi-Fi - OEM Module - with Fully Integrated Support for Digi Device Cloud.
The XBee Wi-Fi Cloud Kit, which fully integrates into Device Cloud, is a simple way for anyone with an interest in M2M and the Internet of Things to quickly build a hardware prototype and integrate it into an internet-based application.
Digi International Inc.
11001 Bren Road East, Minnetonka, MN 55343, USA.
Digi is one of the Pioneers of Device Networking or M2M as it may be called now. Some call the Systems applying these technologies as "Internet of Things - IoT" today (Home and Office Automation).
Derived for this Device Networking term, we have "Wireless Sensor(and Actuator) Networks - WSN" in Industrial Automation. In Robotics it is "Wireless Collaborative Robotics".
If you see above closely, Sensor and Actuators with Intelligence is Robotics. So the dividing line disappears. The human is trying to make the machine more like him, both at work and play. Communications is important for that to happen.

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.
