At 900Mhz I imagine there will be lots of interference problems, or is there something I'm missing?

- structAnkit 11y agoI don't believe we really use cordless phones in the 900MHz anymore and I believe the consortiums determine which spectrums are sufficiently unused before targeting them. Verizon and T-Mobile have some LTE spectrum in the 700MHz range for building penetration and range so I expect to see great things at the 900MHz range for lower power devices.
- revelation 11y agoThey say 900MHz but that's really just a rough ballpark, presumably it will use the 915MHz ISM band in America and 868MHz in Europe.
- BinaryIdiot 11y agoIt's not just cordless phones though. Our baby monitor says it uses 900MHz. I don't know how many types of devices use 900MHz but it seems crowded to me.
