Which modem is Good for 4G LTE TDD network? Keywords: TDD Modem, FDD Modem, 4g tdd modem, 4g fdd modem, TDD band frequencies More and more 4G networks are launched to commercial as time being, many users want to have their own mobile gadgets to experience faster surfing speed. However, there are so many 4G modems on the market now, which one is better? It's a good question. First, we should know some knowledge about 4G Network. LTE and WiMAX are two most popular 4G Network. Since LTE dominates the 4G trend. Today, we would introduce 4G modem for LTE network. As the most popular 4G network, LTE uses TDD and FDD technologies to transmit the data. Subsequently, there are 4G TDD modem and 4G FDD modem. They both have special advantages and weakness. This is not our topic today. Today we talk about the 4G modem for TDD network, i.e. 4G TDD Modems. TDD Frequencies Band & Spectrum LTE BAND ALLOCATION(MHZ)OCATION WIDETH OF NUMBER (MHZ) BAND(MHZ) 33 1900 - 1920 20 34 2010 - 2025 15 35 1850 - 1910 60 36 1930 - 1990 60 37 1910 - 1930 20 38 2570 - 2620 50 39 1880 - 1920 40 40 2300 - 2400 100 41 2496 - 2690 194 42 3400 - 3600 200 43 3600 - 3800 200 Below are the top TDD Modems that are good for 4G TDD networks: 4G modems for band 38(2600MHz): 1. Asiatelco ALT-C180 . 2. Asiatelco ALT-C186 3. Asiatelco ALT-C187 4. Huawei E392-92 5. ZTE MF820S2 6. ZTE MF820T 7. ZTE MF880 8. HUAWEI E392u-21 4G modems for band 40(2300MHz): 1.
