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.

NOKIA BB5 CELL PHONE(RAPGSMv1)
Nokia cell phone that use the processor RAPGSMv1 including ; 3250, 5200, 5300, 5500, 6085, 6125, 6270, 6300, 7370, E50, E62. The processor RAPGSMv1 is the development of processor Tiku (Nokia DCT4 + processor for example 7200, 7600, 6230, etc.) differences among Tiku and RAPGSMv1 IMEI is located on storage security that has been integrated within RAPGSMv1. RAPGSMv1 protocol not supports WCDMA or 3G, only GSM EDGE Class 10 GPRS which can be facilitated.

Schema Baseband Nokia BB5 Cell Phone RAPGSMv1

Specifications RAPGSMv1

  • In and give an accurate square wave out (SYSCLK 19.2mHz)
  • RF Codec that include ADC and DAC converters for the RF signal
RAPGSMv1 given supply voltage Vcore = 1.4 Volt by TAHVO, while RETU will provide voltage VIO = 1.8 Volt and VRFC = 1.8 Volt. RF Clock = 38.4 MHz supplied from the RF module, while Sleep Clock = 32.768 kHz RETU generated from the External Oscillator.
MEMORY
Nokia BB5 cell phone using RAPGSMv1 only need one Combo Memory, Combo Memory neither is a combination of NOR Flash and SDRAM.
NOR Flash (Flash CMT) is used to store program code MCU and DSP, also stores; Tuning Values, Certificates ID, Security IMEI. NOR Flash type has the data capacity of 256Mb.
SDRAM (CMT SDRAM) is used as temporary data storage (Dynamic Data Storage), which has a data capacity of 128 MB.
RF MODULE PART
RF module on the Nokia cell phone type has several important parts, including:
  • RF processor using AHNE 401A
  • GSM Front End Module, is a combination antenna switch and PA
  • External VCO (Voltage Control Oscillator)
  • VCTCXO

NOKIA BB5 Cell Phone (RAP3Gv2)
Nokia BB5 cell phones using RAP3Gv2 include; 6630, 6680, 6681, E60, E70, N70, N71, N72, N90, N91. RAP3Gv2 supports WCDMA Cellular Protocol or commonly referred to 3G. Different with Nokia BB5 cell phones using RAPGSMv1, RAP3Gv2 require additional processor, and then on the phone this type always uses 2 processors inside. Additional processor that is HELEN/OMAP (Open Multimedia Audio Processor), this processor that will assist in managing the UI (User Interface) and multimedia mobile phones such as; Camera, MMC, LCD, Keypad, etc.. OMAP functions can be likened to a Subsystem Body on the UPP Nokia WD2, whereas RAP3G Subsystem is part of the brain in UPP Nokia DCT4.


Schema Baseband BB5 (RAP3Gv2)
RAP3Gv2 (Radio Application Processor)
RAP3Gv2 has a RAM memory that has integrated in it which is used to store software: MCU Subsystem, DSP Subsystem, the Certificate ID and Security IMEI.

GPRS(General Packet Radio Service)

General Packet Radio Service is a technology that allows your phone to transfer data at moderate speeds.
The benefits of GPRS
GPRS lets you send data faster than over a GSM data network, and it's also a lot more efficient. But "data" sounds pretty vague, right?
 
How GPRS works
To use GPRS, you need a phone that supports it, a subscription from your network operator that supports GPRS, and the proper settings.
General Packet Radio Service does what it says: it sends "packets" of data over a radio wave (on the GSM network). Packet switching works like a jigsaw puzzle: your data is split into many pieces, then sent over the network and reassembled at the other end. GPRS is just one of the ways to transport these jigsaw puzzles.
What you can do with GPRS
  • Connect to your office or personal email account to get email as it arrives
  • Browse the Internet on your phone
  • Synchronize your phone and office calendar while you're out of town
  • Download ringing tones, graphics, and games
  • Play online games 
  • Send and receive MMS messages
  • Use your phone as a modem to connect your laptop to the Internet
  • Subscribe to mobile services that bring you personalized information like sports updates, breaking news, horoscopes, share prices, the daily trip-hop-country single...
  • Use Java™-based applications that require a network connection
  • Chat using instant messaging on your phone
  • Update your friends' Presence status
  • Transfer data up to three times faster with an EGPRS (Enhanced GPRS) phone
 
GPRS is better than a GSM connection for data that's transferred in larger "chunks." And unlike voice calls and dial-up Internet connections, you pay for how much you transfer, not for how long you're connected. You can have an active GPRS connection all the time if you like, which is nice if you need to synchronize periodically with a network or if you're expecting an important email.

How it Works

When you talk on a mobile phone, a continuous connection to a channel is reserved for you on the GSM network, which means nobody else can use that channel. With GPRS, you can still have a continuous connection, but you only use the channel when you're sending data.
So, you might be connected to a channel all the time, but you only actually use it when you're sending data. One channel can be shared by many people. This is why you're billed for data transferred, not for time.
GPRS is significantly faster than CSD (Circuit Switched Data, sometimes just called GSM Data). However, you may find transfers slower than the maximum GPRS data rate during peak hours in busy cell networks, because voice connections usually take precedence. The data transfer rate also depends on your device's multislot class, which brings us to the next section.
What does "Class 10 (4+2, 5)" mean?
GPRS classes refer to the slots allocated for uploading and downloading data. The class number, in this case 10, signifies the multislot class. The number 4 in (4+2, 5) refers to the maximum number of slots that can be used for downloading - the more slots used, the faster the data transfer. The second number (2) refers to uploading, and the final number (5, which may or may not be shown), refers to the maximum number of slots that can be used at any one time, both uploading and downloading.
So in this case, we could have 4 downloading and 1 uploading (4+1=5), or 3 downloading and 2 uploading (3+2=5), as a slot can only be used for uploading or downloading at one time. However, you couldn't have 2 downloading and 3 uploading, because that would exceed the maximum number of slots for upload.
Here are some common GPRS classes for Nokia phones - but it's not an exhaustive list:
GPRS Class 2 (2+1, 3)
You guessed it, 2 slots for download and 1 for upload. It's a simple class of GPRS that's found in many phones.

GPRS Class 8 (4+1)
Class 8 reserves 4 slots for downloading and 1 for uploading. This is suitable for Web browsing, and also if you read more email than you send.

GPRS Class 10 (4+1, 3+2)
This profile, which is in the example above, is better for back-and-forth use of GPRS, like instant messaging.

EGPRS (EDGE)
EGPRS (Enhanced GPRS or EDGE) uses a slightly different technology based on what's called 8PSK, or 8-Phase Shift Keying.In practice, it makes GPRS transfers about three times faster, and makes downloading larger files like video less frustrating.
