Nokia BB5 Cell Phone Basic Technology

BASE BAND 5

Baseband 5, generation 5.0 (BB5) technology is the beginning of the development of 3G, NOKIA BB5 Cell Phone until now been developed into 4G technology. Data access speed is very fast, so it can have features that are very powerful, such as internet access speed up to 384 kbps, Video Streaming, Broadcast TV (DVB-H), etc..
Increasingly powerful computerized system, which is used Microprocessor almost equivalent to a desktop computer or laptop, so the technology NOKIA BB5 Cell Phone not only referred to as mobile phones, but computers and mobile media. Features that are owned including: LCD TFT 18 Mega Colors, resolution up to 5 Mega pixel camera, Wi-Fi / Wireless, LAN, GPS, Navigation, etc.

NOKIA BB5 Cell Phone technology has several categories, adjusted for purchasing power of consumers, the specifications have certainly not all the same. NOKIA BB5 Cell Phone including specification differences lies in Microprocessor used, as will be explained below.
