What is the 900 MHz band used for?
The 900 MHz band is currently designated for narrowband land mobile radio communications and primarily used by land transportation, utility, manufacturing, and petrochemical companies.
Can I use 915mhz in Australia?
Although the US also uses 915 MHz, the actual band is wider than ours (902-928 MHz) and it is illegal to use the lower part of the band in Australia.
What can interfere with 868mhz?
868 MHz interference Systems that use the 868 MHz-band (868–870 MHz), for example, thermostats, fire systems, burglar systems, and DIN-transceivers may have difficulty communicating when there is a strong 800 MHz broadband transmitter nearby.
Is 900 MHz unlicensed band?
Unlicensed spectrum includes the 900 MHz ISM band, extending from 902 to 928 MHz, and the 2.4 GHz and 5 GHz bands. To minimize interference, the FCC restricts the maximum transmit power for unlicensed devices and requires the use of spread spectrum technologies.
Is LoRa legal in Australia?
LoRaWAN devices operating on US frequencies (US915 band plan) or European frequencies (EU868) will not work on The Things Network in Australia and are illegal for use here, as they will interfere with existing equipment.
What is the LoRa frequency in Australia?
LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe), 915 MHz (Australia and North America), 865 MHz to 867 MHz (India) and 923 MHz (Asia). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption.
How far can 800MHz travel?
800 MHz range Twenty five miles for 800MHz or higher is a bit much. The higher the frequency, the shorter the reception range tends to be. UHF is typically considered “line of sight”, but 450 MHz can be picked up for up to fifty or more miles. Other things help with the range.
What frequency does home security use?
Wireless intruder alarm systems operate at either 433 MHz or 868 MHz. Overall, 433 MHz is the more effective at penetrating through walls, ceilings etc than the higher frequency.
