High Frequencies vs Low Frequencies
Mobile, posted: 3-Apr-2009 13:42
Every wireless technology uses one or more frequencies to send it's signals. How high or low this frequency is will affect how far the signal will travel.
Some rules of thumb;
Higher the frequency the lower the coverage
more power required to cover same distance
Lower the frequency the better in-building coverage
less likely to be reflected by building material
This is why companies such as TelecomNZ and VodafoneNZ prefer to deploy their nationwide 3G networks at 850 and 900MHz, respectively, rather than 2100MHz. 2100Mhz is primarily used in Urban/high customer density areas due to the smaller cell coverage area required.
