Civilian Wireless Communication Systems in Israel
This list is intended to summarize spectrum usage (carrier and bandwidth) of civilian systems used in Israel.
This is a partial list, please send additions and comments to Dana Porrat,
links are very welcome.
Mobile (Cellular) Telephony
Cellcom uses the GSM signaling standard using carrier frequencies around 1800 MHz, and an older TDMA system around 850 MHz. GSM uses time and frequency hopping, where each band is 200 kHz wide, and the basic time slot is 120 msec / 26 / 8 =0.58 msec. The modulation is GMSK - Gaussian Minimum Shift Keying, this is a form of FSK.
Orange uses the GSM signaling standard with carriers around 900 MHz.
Pelephone uses the CDMA 2000 (RTT-CDMA 1X) signaling standard with carriers around 850-900 MHz and a 1.25MHz bandwidth.
Mirs uses the iDEN signaling standard that is based on QAM signaling. Carriers around 800 MHz and bandwidth is 25 kHz, with up to 6 users per band with TDMA multiple access.
Data Communications
802.11b uses the 2.4 GHz band with bandwidth of 22 MHz per user, its transmitted bit rate can go up to 11 Mbps.
802.11g uses the 2.4 GHz band with bandwidth of 22 MHz per user, its transmitted bit rate can go up to 54 Mbps.
802.11a uses the 5 GHz band with bandwidth of 20 MHz per user, its transmitted bit rate can go up to 54 Mbps.
Bluetooth systems use the 2.4 GHz band.
Cordless Telephones
One common type of 'digital' cordless telephones use the DECT signaling standard with carriers around 1900 MHz.
The bandwidth is 1.728 MHz, and users are time divided, each user gets 2 slots of 10 msec / 24 = 0.42 msec for the uplink and 0.42 msec for the downlink per 10 msec frame.
Also available are systems around 2.45 GHz (the unregulated ISM band). The 900 MHz band is forbidden for use for cordless phones in Israel.
Satellite Television
The standard bands for satellite television are the C-band and the Ku-band.
The C-band uses carriers between 3.7 and 6.4 GHz, and the bandwidth per channel is 36-72 MHz.
The Ku-band uses carriers between 12-18 GHz.
GPS
Civilian GPS systems use carrier frequency of 1575.42 MHz, with bandwidth of 20 MHz.
Public Radio
AM radio uses carriers between 535 - 1605 kHz, and the bandwidth is 10 kHz per station.
FM radio uses carriers between 88 - 108 MHz, with bandwidth of 200 kHz.
Television Broadcast
The PAL B/G standard used in Israel has carriers between 47-804 MHz, with bandwidth of 7 MHz per TV channel.
Microwave Ovens
Emit at 2.54 GHz.
