The new Apple powerbook G4 is the first one
Computer that provides Bluetooth technology 2.0 + EDR.
2.0 + EDR technology is still behind
It is compatible with 1.0.
From the previous version, the highest data transfer rate offered
Transfer of up to 3MBps. Being the first company
Apple will continue to authenticate the system with 2.0 + EDR
To make great use of Bluetooth technology.
Full support
In addition to Powerbook G4 Portable,
Enable other Bluetooth enabled computers
From Apple, including iBook, iMac G5, eMac,
And Power Mac G5.

The implementation of Bluetooth by Apple

A big change in the computer industry. Apple

Back Back in 1998 the first Mac launch.
Since then, Apple has established 802.11 wireless
Network standard with launch
Between the iBook and the airport during 1999. 2003, Apple
I started the airport extreme.
Wireless new 802.11g high speed technology.
Now, Bluetooth will help further strengthen
The dominant position of the Mac in wireless
Communication, helping to keep Apple's
Reputation for being the first to sell

Bluetooth technical operation
Bluetooth is a high speed, low powered radio link
Technology designed to connect phone or other
Portable equipment with little to no work
A user is required. Unlike infrared, Bluetooth
I do not demand a line of place to put in work.
The current prototype circuit is included in the board
It is a much smaller circuit, 0.9 cm square
Board being developed.
One Bluetooth device
Another, they will automatically exchange addresses
And the details of the function. Then they can be established
Security and 1MB link they use
Is required. Protocols for both handles
Very flexible terrain data and voice.
To realize this technology, embed that goal small,
Non close range tranceeivers to
Devices available today. The radio is
2.45 GHz frequency band and up to support 721
Tsutsu ", it's a pair of sharp tips.
Each device will offer a unique 48 bit address from
Connected IEEE 802 standard,
Specify point to point or multipoint. There is the best range
10 meters, it can be extended to 100
There is a device that increases power
Also protected from radio interference by change
Also their frequency, known as frequency hopping.
The important thing is Bluetooth
The device does not drain battery life. Designation
Limit the power consumption of the device
Battery drain pipe. Radio fragments
Consume less than 0.3ma mode wait, which is less,
More than 5% of the power the standard phone uses.
Bluetooth also guarantees warranty on bit
level. Authentication is controlled by
User via 128 bit key. Wireless signals are available
Encode anything up to 128 bits. of
Frequency hopping, Bluetooth already already very
It is difficult to listen.
Baseband protocol is a combination of both
Circuit and packet switch. Slots can be reserved
The same is true for synchronous packets. Each packet
Sent at different hop frequencies.
Normally, packets cover a single slot
You can extend it with a slot in the cover.
Bluetooth or data channel
Three simultaneous audio channels. Therefore,
It is possible to transfer data while talking
at the same time. Individual voice channels
We support 64KB.
From a technical point of view, Bluetooth is very
Sure it is different. That's the best wireless way
In the world, it further exceeds infrared rays. for
Communication on the go is certainly Bluetooth
It is very difficult to compete with
