wireless transmission

Hi all,

I am new to this forum ....i would be glad if guys help me out๐Ÿ˜Ž
all i want is some data related to wireless transmission....like to use which technology...(RF transmission or something like Wi-fi transmission....) did anyone work on wireless transmission??

If possible give information in detail ......like topology or the basic blocks you are thinking about.........
post me website that has some detailed information on topics like these

it would be of great help๐Ÿ˜

Hi Siva,

Wireless communication was introduced by IEEE 802.11b standard. 802.11 b standard can again be classified to be handling infrastructure wireless comunications and Adhoc communications.
In infrastructure communications for eg, you have a specific base station / Access point and the clients commuincation through these AP .
In Adhoc mode, you generally don't have any access points, all the clients could be considered as routers/nodes through which other clients 'hop' to reach the main internet back haul.
from 802.11 b on, there were many more standards introduced for PAN, MANET networks such as 802.15 .

is this what you want to know?

Hi durga,

wat i am asking is about wireless data transmisiion from a sub system to remote station...
using which technology this can be implemented???๐Ÿ˜•

thanks,

It depends on the distance between two nodes. Could you be more specific on you scenario?

The distance between two nodes will be something like 10 miles......

OFDM is the write tech to implement wireless communication. because in OFDM
noise are very less...... it is easy to implement

10miles, either you can use repeaters betwen access points as access points coverage depends again topology and signall strenght elsem something like Land distance WIFI can be used.Sweden used this techonlogy to control whether ballons in stratosphere , so obvios that it can shoot the antenna beam (directive) upto ~250kms.

Hi Shiva,

can you tell me about your project in detail???
and the distance between receiving and transmitiing ends

what about the spread spectrum technology
wifi is over the technology of spread spectrum or ofdm or the hybrid of both.......

assume if i wanna transmit signal for abu 200m range .....my idea of project is to provide accident alertness to hospitals at remote area... its like HOP system.....
