Bluetooth solution
Bluetooth technology takes a small area
Need to remove the network by the next level
Transmission in user intervention
Very low power to maintain battery power. Each
Transmission signal to and from your cell
The phone gives you and uses only 1 megawatt of power
Enough space for your battery to talk.
Bluetooth is it's standard of networking
Working at two levels:
1. It provides an agreement with
Physical level, as bluetooth is a radio frequency
standard.
2. It provides agreement at the level
The product must agree on the protocol
When bits are sent, number of times sent, and transmission method
The parties of the conversation can confirm the message
What you received is the same as what was sent.
Majors draw the fact that Bluetooth is
It is wireless, inexpensive, and automatic. there
The other way around the wire is:
Infrared's lower light's use of lightwaves
It is more frequent than the human eye and is usually
Used in TV remote control.
Bluetooth technology is intended to gain
to solve this problem
Infrared system. 1.0 old standard of
Bluetooth has a maximum transfer rate of 1MB a
Second, while the 2.0 Bluetooth standard can
Manages up to 3.0 megabytes per second. To make things
Better compatible with 2.0 1.0 devices.
As a solution to wireless, Bluetooth
Maintain, eliminate the need for annoying code
My Review It is perfect for them
Who did not talk on the phone, like you
A longer need to hold the phone next to you
Ears-great for those who travel
A lot
The main learning points of Bluetooth
Bluetooth is easily the best of handheld wireless
Technology When it comes to learning, Bluetooth
It becomes very complicated. To help you, you
The following Bluetooth important learning points:
1. Bluetooth is energy efficient and low
Ideal overhead communication protocol
Inter-device communication.
2. Unlike infrared, Bluetooth does not require
Line of sight.
3. Bluetooth depending on the implementation
It can have a range of up to 100 meters.
4. The Bluetooth specification consists of
Foundation Profile Document and Foundation Core
document.
5. The Bluetooth Protocol Stack
Core protocol, cable protocol and even adaptation
protocol
6. Transmitter operates around 2.4
GHz frequency band.
7. Data channel changes frequency, or
Hop, 1,600 second time, assigned 79 between
ISM band channel.
8. Bluetooth uses spread spectrum
Features of frequency hopping RF to ensure it
Independent networking is another
Device is in range.
9. One or more when a piconet is formed
The device opens a channel of communication.
10. Piconet can have a master and up
Seven slaves
Communication of mutual devices is as follows
Based on the concept of channels.
12 All Bluetooth Devices Available
Voice of transmission.
The total capacity of 13 channels is as follows
1 MB per second.
There are two types of 14 channels:
Bluetooth-SCO (Directed Synchronization Relationship)
ACL (asynchronous connectionless).
15 SCO channels are time-oriented,
So mainly used during the transfer time
Important data such as voice.
16 ACL channel is used for ordinary
Communication data.
17 years old included in the packet
2,745 bits in length.
18 In a single piconet, you may be there
To three SCO links including 64,000 bit seconds
Each
19 To avoid collisions and timing problems,
SCO link is a reserved slot configured by:
Master.
20 masters can support at maximum
SCO links with one, two, three slaves.
Slots not reserved for the 21-year-old SCO
Links can be used as ACL links.
22 LMP (Link Management Protocol)
Link level security,
And establishment of communication link.
23 LMP packets are prioritized
Sent via user packet.
L2CAP layer.
24 L2CAP Layer Secures
Acceptable quality of service.
25 Multiple ACL links can not exist
In the L2CAP layer.
