A 2011 update provides data rates up to 1 Gbit/s for fixed stations. WiMax offers a metropolitan area network with a signal radius of about 50 km (30 miles), far surpassing the 30-metre (100-foot) wireless range of a conventional Wi-Fi LAN. WiMAX signals also penetrate building walls much more effectively than Wi-Fi.
WiBro is the South Korean service name for IEEE 802.16e (mobile WiMAX) international standard. By the end of 2012, the Korean Communications Commission intends to increase WiBro broadband connection speeds to 10 Mbit/s, around ten times the 2009 speed, which will complement their 1 Gbit/s fibre-optic network.
The Nokia N810 Internet tablet is an Internet appliance from Nokia, [1] announced on 17 October 2007 at the Web 2.0 Summit in San Francisco.Despite Nokia's strong association with cellular products, the N810, like preceding tablets produced by Nokia, was not a phone, but instead allowed the user to browse the Internet and communicate using Wi-Fi networks or with a mobile phone via Bluetooth.
However, in December 2010, the ITU expanded its definition of 4G to include Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), and Evolved High Speed Packet Access (HSPA+). [2] The first-release WiMAX standard was commercially deployed in South Korea in 2006 and has since been deployed in most parts of the world.
Likewise, 'WiMAX 2', 802.16m, has been approved by ITU as the IMT Advanced family. WiMAX 2 is designed to be backward compatible with WiMAX 1 devices. Most vendors now support conversion of 'pre-4G', pre-advanced versions and some support software upgrades of base station equipment from 3G.
The Samsung Galaxy S II WiMAX ISW11SC is an Android smartphone developed by Samsung Electronics, and sold by au in Japan. It is the first phone in the Galaxy series, and is the final model to be compliant with the WiMAX Standard.
