The AP350 is a 100 milliwatts or +20dBm. The 'duck' antenna that ships with the unit has 2.2dBi of gain.
The dBi rating indicates gain over an isotropic radiator - a theoretical perfect point radiator in free space. The 2.2 dB of gain indicates that there is a little bit of focusing of the radiated energy towards the horizon when the antenna is mounted vertically. To figure out how far out you can get a signal you'd need to know the receive sensitivity of the client radio in use (-75dBm for 2 meg ... this is the only rule of thumb I carry in my head) and the receive gain of the client antenna. If you're talking to PCMCIA cards they're nasty - essentially no gain. You'd need to figure the loss to find out if the observed signal at the receiver is greater than the receive sensitivty. Examine this URL: http://www.qsl.net/n9zia/wireless/ There is a lot of information in here about 2.4 gig radio performance and in particular there are a lot of nice equations that show how to calculate link loss and all sorts of other stuff you need to know. This is a little tense for indoor use - but I've shot Aironet 342 over a 22 mile link :-) IT Guy wrote: > > Hi guys, > > Need to clear an small confusion?? > > As we know Range for 350 AP at 11 mbps is 130 ft??What does it mean?? > 130 ft horizontal or vertical or both??? > > Thanks for removing my confusion. > > _________________________________________________________________ > Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- Neal Rauhauser CCNP, CCDP voice: 402-391-3930 http://AmericanRelay.com fax : 402-951-6390 mailto:[EMAIL PROTECTED] fcc : k0bsd Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=23825&t=23758 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
