Can a Wireless PCMCIA Card Extend Internet Access Beyond 100m?

AI Thread Summary
A wireless PCMCIA card can potentially extend internet access beyond 100 meters, but achieving this requires specific equipment and setup. Directional antennas are necessary to focus the signal effectively over longer distances, especially in open areas like parks. The user suggests that a wireless modem may be needed for the laptop to connect to the internet source. Most standard routers have a range limit of about 100 meters, so additional solutions are essential for extending the connection. Overall, while it is feasible, careful planning and the right technology are crucial for success.

I had an idea the other day that if I could set up a wireless connection from my laptop to my pc which is connected to the internet via cable I could work on my laptop down the road (in a pub or park depending on the weather) I guess it would involve some protocol like bluetooth has anybody done a similar thing ?

Should not be to much much of a problem got a new place in a loft conversion which is higher than most other surrounding buildings and has visual of the park I was thinking chilling out err working in ~ 100 meters. But I guess I would need some sort of wireless modem or somthing to stick in my laptop for the other end as well.
 
you need a wireless PCMCIA card for your laptop. most routers only transmit up to a 100m so you will need some way of getting the signal a little farther.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
