Mobile Broadband < b > < /b > technology | Core of knowledge

the mobile broadband technology enables wireless high speed Internet via modem laptop. With this technology, the digital information sent and received using radio signals. Same technology used for mobile phones. The main difference between normal cells and mobile broadband technology is that is communicated, in the first case, the voice data and in the latter case, other data such as Web pages, E-mails are transferred to different kinds of files. Various standards WiMAX, Flash-OFDMA, assuming by the mobile broadband technology, GPRS, IPW, LTE, 3 g EV-DO, etc.. Standard EV-DO and EDGE far into the GSM network during HSDPA, HSUPA and HSPA 3 G FOMA serve employees and UMTS network under

Categories of network technology

Technologies of the mobile phone can be divided into two categories:. global systems for mobile communications (GSM) and division multiple access (CDMA). These two technologies are very popular all over the world. Europeans, Americans prefer that GSM is the first choice is CDMA. The main difference between these two technologies technology is based on the exchange of space on the airwaves. Different algorithms used by these two technologies. This feature enables many mobile phone users of radio frequencies without sharing in the networks of other diseases.

3 G

The most popular among the standard rules of 3 g mobile broadband technology, identification technology generation or the third generation mobile communications. At the same time, this technology was developed by GSM and CDMA. Both networks use their own version of 3 g technology on high-speed Internet users access.

GSM network functions

GSM broadband networks use technology and offer HSDPA. HSDPA is the abbreviation for high-speed downlink packet access link. HSPDA enabled network send and receive data and voice signals. This unique technology can browse users on the Internet and speak at the same time. This speed data transmission technology increased significantly, with emphasis on the downloading of data on. The average download speed of HSDPA is 400 kbit/s-700 kbit / S. special networking hardware is required, to HSDPA mobile broadband access. A PC card with the features of broadband could be connected a laptop is a popular device. Also, a device with HSDPA card function could be used. It is imperative to me the range of HSDPA signal range.

CDMA network functions

EV-DO technology is used for the Wideband CDMA networks. EV-DO evolution data are optimized. Operating the air, that the data is given only in a part. A large amount of bandwidth for voice calls required. The data transfer rate increases CDMA networks primarily because of the separation of the data channel of a voice channel. Increase the speed of the network and thus multimedia, E-mail and Internet functions much faster. The disadvantage of the CDMA is to continue the conversation and surfing the Internet at the same time. The average speed EV-DO is 300 KBit/S-400 kbit / s. Is required for an EV-DO-DO hardware. This hardware is usually a laptop via a USB port or other standard PC card slots. It is used as an antenna to send and receive broadband signals. The device in the field of EV-DO must be for a fast mobile broadband.
