As I only use wireless for LT's that are taken out of the office and make use of hot spots for Internet connection and e-mail.
For office environments I avoid Wireless just for security reasons as even with the 802.11 G it can be read up to 500 meters away so even if I do manage to lock down all my data I can never be sure that some unauthorized person is not using the Internet and running up my clients bills.
I have seen several Lt's placed in the office network with 802.11G wireless cards and being unknown to the powers that be and they are used after hours by staff to access the Internet. In a severe case someone downloaded 200 GIG of data and that was well in excess of that companies ISP agreement which worked out as quite expensive. If I had not have walked around the business with a LT with a wireless connection and found a hot spot I would never have found the LT that had been placed in the suspended ceiling. At least the person responsible had locked down all the company data but had left a connection available for anyone who wished to use the Internet.
