The video was filmed on a Keynote conference in 1999, where Steve Jobs introduced the iBook G3. It was the first computer that carried an inserted Wi-Fi card. It was the first time Wi-Fi was introduced to the masses. To prove that the technology was really wireless, Steve Jobs used a Hula Hoop to put the laptop through it.
On this historic conference Jobs said that 'everyone' would jump on the 802.11 bandwagon in the next few months/years. "We're just going to be there first, and the best," Jobs said.
The video shows Jobs surfing the net from an iBook that was just woken from sleep. Nobody in the audience was aware that Jobs was using a wireless technology, so when he stood up, picked up the laptop and walked around the stage, opening webpages wirelessly, the crowd roared with applauses. Then he put the laptop through a hula hoop to show that the Internet collection was indeed wireless.
Google has recently released its new Nexus 7 - a budget tablet, which costs only $229 for the version with Wi-Fi and 16GB of memory. But can this device compete with the iPad mini, released in October 2012? Let’s find out.
Samsung Galaxy S 4 looks a lot like last year's Galaxy S III model. But there are of course some differences, most notably on the inside. Let's compare some specs:
This year Apple plans to add a high speed 802.11ac wireless networks to its lineup. AppleBitch notes that Apple created a list of job duties for a System Test Engineer with experience in 802.11 network environments.
iPad Mini is 23 percent thinner and 53 percent lighter than iPad 3. It is just 7.2mm thin, and weights 0.68 pounds. The new iPad mini features a 7.9-inch Multi-Touch display, A5 CPU, FaceTime HD and 5MP iSight cameras, 10 hours of battery life, fast 802.11n 150 Mbps Wifi and worldwide LTE. iPad mini features the same number of pixels (1024 x 768) as the original iPad and iPad 2, so it is possible to run and use all 270000 apps designed specifically for iPad. The best part is that you can hold in one hand.
The iPad Mini price starts from $329 for 16GB Wifi model up tp $659 for 64Gb WiFi+3G/4G:
It is 18% thinner than the 4S, just 7.6mm. It's even 20% percent lighter at 112 grams. The in-cell retina display is 4-inch with 1136 x 640 resolution. Apple says new iPhone 5 has a better color saturation with full sRGB rendering. That new longer screen allows for an extra set of icons to be displayed on the home screen, and first party apps have already been tweaked to take advantage of additional pixels. The tweaked ratio puts the iPhone 5 display closer to 16:9, but it's not quite there.
iPhone 5 supports worldwide LTE as well as HSPA+ and DC-HSDPA. 802.11n Wi-Fi can connect at 2.4ghz and 5ghz. Performance is said to be 2 times faster with new A6 processor. iSight camera features 8-megapixel sensor, backside flash, hybrid IR filter, five-element lens, sapphire lens, f/2.4 aperture, next-generation ISP, spatial noise reduction, smart filter, better low-light performance, 40 percent faster on photo capture, and HD video recording (1080p) up to 30 frames per second with audio.
Front FaceTime HD camera has 1.2MP sensor, improved video stability and is capable of recording HD video (720p) up to 30 fps. Audio system was also improved. iPhone 5 has 3 mics and improved speakers.
The new 802.11ac standard achieves much faster wireless networking speeds than the existing 802.11n specification (in use on the latest Mac, AirPort and iOS devices) by using 2 to 4 times the frequency bandwidth (from 80 to 160MHz), more efficient data transfers through sophisticated modulation, and more antennas (up to 8; existing standards support up to 4, while Apple's Macs currently use up to 3).
This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.
