solar system has a different density of the atmosphere outside our atmosphere‚ the PSL would have confirmed Voyager 1’s exact whereabouts. The Voyager does however have two functioning antennas that detected abnormal vibrations‚ leading scientists to believe its debut into interstellar space. Those same two antenna have also recently detected oscillations (variations in magnitude or position) that suggest the surrounding plasma was cold and dense. Scientist Ed Stone addresses this information to be

Zigbee and Xbee ZigBee is a standard defined by the IEEE ( Institure of Electrical and Electronics Engineers) back in 1998. When a group of big guy say WiFi and Bluetooth might not be suitable enough for some applications‚ they started to define new protocol‚ new standard. ZigBee aim to have lower data rate compared to Bluetooth‚ at 250Kbps (Bluetooth is 1Mbps back then‚ now is higher with EDR-Enhanced Data Rate). More importantly‚ ZigBee aims for lower power applications which should offer years

Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

Wi-Fi Technology Introduction: Electrical technology has been greatly enhance with the introduction of wireless communication. Wi-Fi is the one among the achievements. The term Wifi stands for Wireless fidelity. Wi-Fi is a brand originally licensed by the Wi-Fi Alliance to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications. It was developed to be used for mobile computing devices‚ such as laptops‚ in LANs‚ Internet

The types of language the author used made me more interested in the book because they would appeal to me more because they seemed more scientific. As well as this the author used many acronyms like HAB (habitation module). The beginning of this text made me want to keep reading because I thought he died By getting impaled on a radio antenna that was his only way to contact earth and I wanted to
