Also at the SEK show in South Korea: Samsung shows off a global-roaming WCDMA phone LG Electronics unveiled several cellphones on Wednesday that support HSDPA (high-speed downlink packet access) wireless data connections.The phones, displayed at the SEK exhibition in Seoul, attracted a steady flow of visitors, all of whom seemed eager to try out the handsets.HSDPA is being deployed on WCDMA (wideband code division multiple access) networks, of which there are two in South Korea. The version of the technology in use in the country allows a maximum theoretical download of 3.6Mbps, although actual speeds are likely to be slower. The LG-KH1400 marries the HSDPA networking with reception of digital mobile television. The phone’s display can be twisted into a horizontal orientation so TV programs can be better enjoyed and there’s also a video output socket so an even bigger screen can be fed with the picture. The handset also has a 2-megapixel camera.Alongside it in the LG Electronics booth sat the LG-SH130. This handset is a more basic slider model that brings fast data and global roaming without all the bells and whistles of the other phone.Global roaming is still a fairly new concept to most South Koreans due to the reliance of all cellphone carriers on CDMA (code division multiple access), which is only used in a handful of countries, so the ability to use a single phone worldwide is still something of a novelty. Samsung Electronics was showing a global-roaming WCDMA phone, the SPH-M6200, that didn’t offer fast networking.The Windows Mobile 5.0-based phone packs tri-band GSM (global system for mobile communications) with WCDMA and offers 802.11b/g Wi-Fi and Bluetooth 2.0. Under the 2.3-inch, QVGA (240 pixels by 320 pixels) resolution screen is a QWERTY keyboard. The phone also includes a browser for the conventional Internet and a 1.3-megapixel camera.
