1. TM1, single antenna port transmission: mainly used for single antenna transmission.
2. TM2, transmit diversity mode: suitable for the situation where the cell edge channel is more complicated and the interference is greater, and sometimes also used in high-speed situations.
3. TM3, open-loop space diversity: suitable for high-speed mobile terminal (UE).
4. TM4, closed-loop space diversity: suitable for occasions with good channel conditions, used to provide high data rate transmission.
5. TM5, MU-MIMO transmission mode: mainly used to increase the capacity of the cell.
6. TM6, Rank1 transmission: mainly suitable for the cell edge.
7. TM7, Port5 single-stream Beamforming mode: mainly at the cell edge, it can effectively combat interference.
8. TM8, dual-stream Beamforming mode: can be used at the cell edge or in other scenarios.
9. TM9, transmission mode 9 is a newly added mode in LTE-A, which can support transmission up to 8 layers, mainly to increase the data transmission rate.
Auto spare lamp kits are extra lamp pieces that can be used to replace a piece that broken. There are many different bulbs and fuses in one spare lamp kits. For example, there are one H4 for headlight, one S25 singe filament for signal light, one dual filament S25 for stop light, one G18.5 for truck light or license plate light, one T10 for interior light or side indicators light and two different types of fuses that can replace the burned fuse. The customers will review what specs their own vehicle have and choose which to buy. Having a spare lamp in the car is like buy a insurance, because every light on the car has its specific purpose, which means any broken bulb might put the driver and others in a very dangerous situation. Highly recommend have one kits in the car.
