A lot of wearable antennas are produced for ISM bands
Powercast's (Pittsburgh, PA) new TX91501 Powercaster Transmitter uses the 915-MHz ISM band
to transmit common radio waves for power and data.
RFMD's highly integrated RF3482 single-chip FEM integrates a WiFi power amplifier with a single-pole, three-throw (SP3T) switch for 2.4 GHz to 2.5 Ghz ISM band
Melexis' RF product portfolio includes ISM band
transmitters, receivers and transceivers along with RFID and wireless sensor tags.
Operating in the 900 MHz ISM band
, in indoor/urban applications, the units can communicate through as many as 10 walls using the included 2.5 dBi omnidirectional antennas.
The radio uses frequency hopping spread spectrum (FHSS) technology in the 2.4-2.4835 GHz ISM band
, which is an international band.
The text then covers the important specifications of an open-standard (IEEE 802.15.4) protocol radio application-specific standard product (ASSP) and a proprietary protocol radio ASSP, both of which are targeted at the unlicensed 915 MHz ISM band
The Bluetooth radio operates in a globally available 2.4 GHz ISM band
, enabling communication compatibility worldwide between a wide range of home, business, and general-purpose electronic systems.
Thus, the problems caused by multipath increase in the 2.45 GHz ISM band
; however, this band is more interesting for communication purposes (such as Zigbee) than are lower ISM bands
because of the larger bandwidth available.
The ISM band
frequency spectrums can be used by anyone without a license.
Meshnetics (Dresden, Germany) introduces the new ZigBit 900, an ultra-low power 802.15.4/ZigBee RF module for Sub-1 GHz ISM band
. The module comes bundled with the ZigBee PRO mesh networking software and is ideal for use by system integrators and OEMS.
Operating in the 5.725-GHz to 5.850-GHz ISM band
, it delivers aggregate rates up to 310 Mbps at distances up to 20 miles.
The products are well suited as an IF local oscillator or mixer local oscillator driver for various 2.4 GHz spread spectrum transceiver chipsets, IQ modulators, mixers, and 802.11b (WLAN) and ISM band
The ISM band
radio chip is based on compatibility with the IEEE 802.11b and g standards and employs standard, low-cost CMOS integrated circuit technology.
