And the winner is …. SIMCom SIM8262E 5G modem! Please read bellow and compare
LTE modem SIMCom SIM8262E (5G modem)
cooling : none
connection : USB A -> mPCIe converter + mPCIe -> m.2 adapter (USB 3.0)
Consumption :
o idle (4G): 0.3-0.5, at ping (5G) jumps up to 1.3 W
o flood ping (5G): 1.2-1.9 W (mostly ~1.6 W)
o speedtest (5G): varies widely 2.1W-4.5 W, speeds vary from about 10 Mbps
Temperature :
o idle: ~39 ˚C
o flood ping: ~62 ˚C
o speedtest: ~83 ˚C
LTE modem Telit LM940
cooling : none
connection : modem plugged in USB to mPCIe converter
transmissions: alternately approx. 90 Mbps download and 30 Mbps upload
Consumption :
– when actively transmitting 2.2-3 W
– aggregation 2100 MHz/20 Mhz + 1800 MHz/20 MHz and 800 MHz/10 MHz
– when uploading about 0,5 W higher
– during simultaneous upload and download consumption at the level of separate download
– during flood pinging the modem runs only on 2100 MHz, the remaining aggregated bands are inactive – consumption ~1 W
– when inactive consumption fluctuates between 0.3 W and 1 W
– AT commands – once every 30 s check ping
Temperature :
– settled to 38 ˚C when inactive
– climbed to 73 ˚C when active
LTE modem Telit LM920
cooling : none
connection : USB A -> mPCIe converter + mPCIe -> m.2 adapter (USB 3.0)
transmissions: alternately approx. 70 Mbps download and 30 Mbps upload
Consumption :
+ at rest (no explicit load, only MMngr) varies between 0.25 W and 1 W
▪ at worse signal (without antennas) higher on average by about 0.3 W, (0.25-1,3 W)
+ flood ping ~0.75 W (2100 MHz/20 MHz) (very stable, repeatedly measured)
▪ flood ping + speedtest as flood ping alone
+ speedtest in loop: fluctuates between 1.5 W and 2.5 W
▪ when uploading ~0.5 W higher (1.5-2 W/2-2.5 W)
▪ band aggregation • 2100/20 MHz • 1800/20 MHz • 800/10 MHz
Temperature :
– flood ping ~46 ˚C
– without explicit load ~36 ˚C
– speedtest ~68 ˚C
Cinterion MV32-W (5G modem)
cooling : none
connection : modem plugged in USB to mPCIe converter
transmissions: 5G avg. 130/50 Mbps
LTE avg 145/60 Mbps
after some time it disconnects from the mains (thermal fuse?)
Consumption :
o FW: FDE.F0.0.0.1.3.DT.004.046
o connection: reducer USB-A -> mPCIe + mPCIe -> m.2
o consumption (increases noticeably with modem temperature):
o AT+CFUN=0: <0,5 W
o idle connected: 0,5 W
o 5G
▪ flood ping: 2–2,2 W
▪ speedtest: 3–3,5 W/3,5–4,5 W (Down/Up)
o LTE mode
– flood ping: 1,3–1,5 W
– speedtest: 2,2–3 W / 3–6 W (Down/Up)
Temperature :
o AT+CFUN=0: 38 ˚C
o idle connected: 38 ˚C
o flood ping (5G): 70 ˚C
o flood ping (4G): 56 ˚C
o speedtest (5G): 85+ ˚C (connection lost)
o speedtest (4G): 85+ ˚C (connection lost)
