From IEEE 802.11-1999 7.3.2.17.3.2.1 Service Set Identity (SSID) element  The SSID element indicates the identity of an ESS or IBSS.  See Figure 35.  The length of the SSID information field is between 0 and 32 octets.  A 0 length information field indicates the broadcast SSID.That's a bit misleading as the SSID is sometimes null terminatedleaving only 31 characters available.  Some firmware versions screw upif you use the full 32 characters.Spaces are just fine.  Some utilities will blow up if you do that, butmost access points handle it just fine.Maximum humor, keep it clean, forget about bell characters, and nonulls.

I tried something like that. The Linksys "fill in the blank" SSID setting on the web page will only accept real printable characters. I had to use SNMP to install the goofy SSID. Then, I found that the XP WZC client would not accept the backspace character (or a bunch of other cursor position characters). I suspect it's that way for most menu driven setup utilities and web pages. So, I gave up. Currently it's something like "Virus Testing Lab #123".
