Channel spacing is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan.
Decided that the frequency bands 1525 - 1544, 1545 - 1559, 1610 - 1626.5, 1626.5 - 1645.5, 1646.5 - 1660.5 and 2483.5 - 2500 MHz may be used for the satellite component of IMT-2000, as well as the bands 2500 - 2520 MHz and 2670- 2690 MHz, depending on market developments
The WCDMA system is specified in 3GPP for all the following frequency bands
Main differences between WCDMA/High Speed Packet Access (HSPA) and GSM/Enhanced Data Rates for GSM Evolution (EDGE) networks, e.g.
3GPP also specify a new radio system called Long-Term Evolution (LTE), where the target for finalizing 3GPP standardization is during 2007
