4G Technology

There is two new products made in Option Wireless Technology introduced in marketing, namely GlobeSurfer iCon 72 ( upper right photograph) and GlobeTrotter Express 72 ( middle photograph) what has separate keunikan compared to other conspecific product.

Numeral 72 at both the products indicates that both the products ready for applied at network access 3,5G with speed reachs 7,2 Mbps, quicker compared to conspecific product of which only can reach speed of access 3,5 Mbps.

In technology 3,5G actually is recognized two technology types to differ in speed of network access seluler. There is technology so-called as HSDPA ( High-Speed Downlink Packet Access) a real popular in technology wideband CDMA opens high-speed broad band up to 3,5 Mbps.

There is technology so-called as HSUPA ( High-Speed Uplink Packet Access) frequently is called as technology 3,75G, or even also is conceived of technology 4G. Technology HSUPA of course untapped in operator tissue system seluler, but difference that is enough signifikan will felt when service user 3G as a whole fiddles around with data in large size above 1 MB.

Difference between HSDPA and HSUPA lays in speed of downlink with speed of total maximum reachs 3,5 Mbps, and speed of total uplink reachs 7,2 Mbps. Technological in family UMTS ( Universal of Mobile Telecommunications System) this presents standard enabling telecommunications service to become effective from the angle of cost, high-speed data service service, and service service VoIP ( Voice over Internet Protocol).
