I was shopping for a replacement for my current 2.4GHz cordless phone today because it keeps interfering with the 802.11g network I installed at home. I specifically wanted a 5.8GHz model so I wouldn't have to worry about conflicting with my wireless home network. I found a nice looking 5.8GHz Vtech at Wal-Mart with 3 handsets. Looked nice, and 5.8GHz -- perfect, right? I thought so. I bought it over lunch and during the day I took a look at the manual. Back on the technical specifications page, the truth revealed itself. Yeah, the phone base did transmit to the handset at 5.8GHz, but the handset transmitted back at 2.4GHz! What B.S. Nowhere else on the packaging or in the manual did it mention this. I think it's wrong for the company to advertise a phone as 5.8GHz if it actually uses both 5.8GHz and 2.4GHz. The only reason I looked was because I had read yesterday in consumer reports that a couple of phones advertised as 5.8GHz actually used both frequencies. What a crock. Had I not specifically looked for this, I probably would have been scratching my head as to why my '5.8GHz' phone was interfering with my 2.4GHz network. Anyway, I took the phone back to Wal-Mart and picked up a 3 Handset Panasonic. Before actually purchasing it, I pulled out the manual and checked the technical specifications. The Panasonic was in fact a true 5.8GHz phone, transmitting in that frequency for both the handsets and the base. So anyone else out there looking for a 5.8GHz phone to avoid network interference, be sure to look past the box and check out the technical specs.
