join the two wired network with wireless

[alvi]

friends

i have two problems

i am running my cable net. first of all tell me what is the best way for cabling
(in cable secure point of view )
under ground or over bulidings/houses

oops it is related to networking not wireless net

anyhow 2nd problem is

now i want to join two wired area network with wireless.
the reason behind is because of main road and it is not possible for me the
to cross the road with wire (underground or over ) because of my government policy.

what can i do know ?
tell me the easiest and not costly solution

Now, with this, i could be wrong, but i believe if you got a couple of wireless routers, and wired them into the hard wired network, and set them up accordingly that you should be able to use them to join the 2 networks.

Other than that (i dont know if there is such a thing) but a wireless bridge should do the job aswell.
