Keepout, and restrict polygons are powerful tools at your disposal as a PCB designer. Keepout is used when you don't want components placed within an area, like edges of a board, or where your heatsink will be placed.
The stock firmware included on many broadband routers takes advantage of only a fraction of the hardware's capabilities. We explain how to use use powerful open-source firmware to unleash the beast in your router.
Phil Torrone sez, "Learn to make a speaking, card-reading toy! The Babel Fish helps you learn to say words and phrases on RFID flash cards by reading the card and playing an associated sound file loaded on an SD card inside.
Internet gateways (i.e. WiFi access points) are already used so IoT devices could have direct connectivity to the Internet without the need for additional infrastructure (setup cost, maintenance cost, etc.). Almost every smartphone is WiFi enabled, so communication with WiFi devices is quite easy and direct without the need for additional hardware. It is an established standard, supporting a full TCP/IP stack, meaning that when developing applications you need to focus only on the application level programming for message and information exchange. Integrates security
Cost (even the Electric Imp at 25$ is much more expensive than a pair of RF transceivers) Even low power WiFi has more power consumption than RF (and also the communication protocol introduces much unnecessary overhead) Low power has poor indoor performance RF on the other hand has also great benefits over WiFi in the context of M2M:
Higher transmission range and better indoor performance Better price
Standards like ZigBee and 6LoWPAN include security implementations and mechanisms for error corrections/retransmission, etc. so that developers can focus just on the application level as well.
