Band 3 is a standard LTE band and here is some introduction for the corresponding band
Ø Band type = FDD
Ø Common Name = DCS
Ø Uplink Frequency= 1710-1785 MHz
Ø Downlink Frequency= 1805-1880 MHz
Ø Channel Bandwidths= 1.4, 3, 5, 10, 15, 20Mhz
eLTE Solution will use the guard band of Band 3. Then the operating frequency of eLTE Rapid is 1785 MHz - 1805 MHz and the band width is 20 MHz
[ 1710-1785 MHz ] === [ 1785Mhz – 1795Mhz (center) – 1805Mhz ] === [ 1805-1880 MHz ]
Problem Description
eLTE System can work in the guard band of the Band 3. However in that case there
can be interference since Band 3 is a standard LTE frequency and carriers are
using it. Therefore to be safer regarding with interference eLTE can be used
with 10 MHz bandwidth like;
[ 1710-1785 MHz ] ===
[ 1790Mhz – 1795Mhz (center) – 1800Mhz ] === [ 1805-1880 MHz ]
eLTE can be operate in both Band 62 and B59, for the details of such bands one can check Figure 1.
The difference band 59 and 62 is the following; they both are same frequency, and they are referring to
different EARFCN, because Band 62 is just for Huawei, however, Band 59 is used by other companies as well.
Figure 1: EARFCN values for Band 59 and Band 62
Proposed Solution
For operating rapid in 1790-1800MHz, Downlink EARFCN will be selected as 64836 and uplink and downlink bandwidth will be selected as 10Mhz.
