Communication Devices

ipad       
iPad (pronounced /ˈaɪpæd/ eye-pad) is a line of tablet computers designed, developed and marketed by Apple Inc. primarily as a platform for audio-visual media including books, periodicals, movies, music, games, and web content. Its size and weight fall between those of contemporary smartphones and laptop computers. The iPad runs the same operating system as the iPod Touch and iPhone—and can run its own applications as well as iPhone applications. Without modification, the iPad will only run programs approved by Apple and distributed via the Apple App Store (with the exception of programs that run inside the iPad's web browser).
Like iPhone and iPod Touch, the iPad is controlled by a multitouch display—a departure from most previous tablet computers, which used a pressure-triggered stylus—as well as a virtual onscreen keyboard in lieu of a physical keyboard. The iPad uses a wireless local area network ("Wi-Fi") connection to access local area networks and the Internet. Some models also have a 3G wireless network interface which can connect to HSPA or EV-DO data networks and on to the Internet. The device is managed and synced by iTunes running on a personal computer via USB cable.

P1 Wimax
Packet One Networks (P1) is a Malaysian converged telecommunications, broadband and Wimax service provider. The company was founded in 2002 and is a subsidiary of Green Packet Berhad. In March 2007, P1 was one of four companies awarded 2.3 GHz spectrum licenses by the Malaysian Government to deploy WiMAX services throughout Malaysia. In August 2008, P1 became the first company to launch commercial WiMAX services in Malaysia

Wifi             
Wi-Fi ( waɪfaɪ) is a mechanism for wirelessly connecting electronic devices. A device enabled with Wi-Fi, such as a personal computer, video game console, smartphone, or digital audio player, can connect to the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 ft) indoors and a greater range outdoors. Multiple overlapping access points can cover large areas.
"Wi-Fi" is a trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards. Wi-Fi is used by over 700 million people. There are over four million hotspots (places with Wi-Fi Internet connectivity) around the world, and about 800 million new Wi-Fi devices are sold every year. Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" designation and trademark.

Galaxy Tab               
The Samsung Galaxy Tab is an Android-based tablet computer produced by Samsung introduced on 2 September 2010 at the IFA in Berlin.
The Galaxy Tab has a 7-inch (180 mm) TFT-LCD touchscreen, Wi-Fi capability, a 1.0 GHz ARM Cortex-A8 ("Hummingbird") processor, the Swype input system, a 3.2 MP rear-facing camera and a 1.3 MP front-facing camera for video calls. It runs the Android 2.2 (Froyo) operating system, and supports telephone functionality as speaker phone, via provided wired ear piece or Bluetooth earpieces (except models sold in the US). It can download videoconferencing apps such as Tango as alternative to telephone functionality.[
