LTE-Advanced（The LTE system of upgrade version）Peak rate reaches 1Gbit/s under Hypomobility, and height is mobile
Peak rate reaches 100Mbit/s under property.In order to support that such peak rate often needs bigger bandwidth.And so big band
Wide frequency spectrum is difficult to find.Carrier aggregation（Carrier Aggregation, CA) become the necessarily choosing that operator faces the future
Select.
Carrier aggregation is exactly scrappy LTE（Long Term Evolution）Frequency range is merged into one " virtual " more
Wide frequency range, to improve data rate.The frequency range of LTE systems is divided into low frequency（LOW BAND, abbreviation LB）, intermediate frequency (MIDDLE
BAND, abbreviation MB) and high frequency (HIGH BAND, abbreviation HB).Frequency range that LTE systems are typically used for, English are called band, letter
Claim B.As shown in the table 1 that following common frequency ranges are divided.
| Coverage is referred to as | Frequency band list | Frequency range |
| LB（Low frequency） | B5/B8/ B12/B17/B20/B28 | 734MHz ~ 960MHz |
| MB（Intermediate frequency） | B1/B2/B3/B4 | 1805MHz ~ 2170MHz |
| HB（High frequency） | B7/B38/B40/B41 | 2.2GHZ-2.7GHZ |
