The first most obvious consideration is the radio or RF coverage required within the facility, the size and design of the facility will determine the number of wireless access points required to provide that coverage. Another consideration will be selection of the appropriate wireless antennas to provide the desired coverage. The wireless antenna is one of the most important components of any wireless access point or wireless client device, because it is the antenna that determines how the radio signals are propagated, what type of radiation pattern they produce and how much gain they produce. The radiation pattern may be isotropic, meaning that the antenna radiates the signal equally in all directions, and we often refer to these antennas as omni-directional. Depending on the siting of the antenna, we may need a radiation pattern than is not isotropic, but radiates in a pattern that maximises the radio signal in a certain direction.Wireless Antenna]]> Wireless Aerial]]> Wireless]]> Antenna]]> Aerial]]> 802.11b]]> 802.11g]]> WiFi]]> WiFi Antenna]]> http://www.articlesnatch.com/Article/What-Type-Of-Wifi-Antenna-Do-I-Need/3643314 Thu, 09 Feb 2012 11:05:35 -0500 http://www.articlesnatch.com/Article/What-Type-Of-Wifi-Antenna-Do-I-Need/3643314 PHP Web Development India]]> http://www.articlesnatch.com/Article/Php-Development-Company-India-Selects-Php-For-Web-Development/3630055 Mon, 06 Feb 2012 01:44:03 -0500 http://www.articlesnatch.com/Article/Php-Development-Company-India-Selects-Php-For-Web-Development/3630055 PHP Web Development India]]> http://www.articlesnatch.com/Article/Php-Development-Company-India-Selects-Php-For-Web-Development/3630029 Mon, 06 Feb 2012 01:38:41 -0500 http://www.articlesnatch.com/Article/Php-Development-Company-India-Selects-Php-For-Web-Development/3630029 Toronto, Canada - GAO RFID Inc.

Bluetooth wireless communications is one instance of a WPAN technology. Bluetooth wireless technology fills this important communication need, with its ability to communicate both voice and data wirelessly, using a standard low-power, low-cost technology which can be integrated in all devices to enable total mobility. The Bluetooth module is a small and extremely lightweight device that is part of the electronic guts of many devices that we use in day to day life. Bluetooth protocols allow an astonishing array of digital devices from personal computers to cell phones and even game consoles to communicate with one another securely over short distances, under 100 meters. Bluetooth modules should be able to receive transmissions from the PC from a distance of at least 70 ft indoors. We wish to be able to transmit this far even with walls and other obstructions included. The cycle time for sending a command and receiving some sort of feedback should be kept below 2 minutes. The largest variable that will affect this will be the response time of the POP3 mail account.Bluetooth]]> Wireless]]> Communication]]> module]]> electronics]]> ]]> http://www.articlesnatch.com/Article/Bluetooth-Modules-Providing-Bluetooth-Wireless-Communication/2590956 Wed, 22 Jun 2011 04:23:40 -0400 http://www.articlesnatch.com/Article/Bluetooth-Modules-Providing-Bluetooth-Wireless-Communication/2590956 Microchip expands RF power amplifier portfolio New devices are ideal for embedded WLAN applications requiring small size, high efficiency and low battery-voltage operation Bangalore, 21 June 2011: Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the expansion of its RF power amplifier portfolio, with the addition of the new SST12LP17E and SST12LP18E devices.
