Editing Channel access method (section)

==Hybrid application examples==
Note that hybrids of these techniques are frequently used. Some examples:
 
* The [[GSM]] cellular system combines the use of frequency-division duplex (FDD) to prevent interference between outward and return signals, with FDMA and TDMA to allow multiple handsets to work in a single cell.
* [[GSM]] with the [[GPRS]] packet-switched service combines FDD and FDMA with [[slotted Aloha]] for reservation inquiries and a [[dynamic TDMA]] scheme for transferring the actual data.
* [[Bluetooth]] packet mode communication combines [[frequency hopping]] for shared channel access among several private area networks in the same room with [[CSMA/CA]] for shared channel access within a network.
* [[IEEE 802.11b]] [[wireless local area network]]s (WLANs) are based on FDMA and [[DS-CDMA]] for avoiding interference among adjacent WLAN cells or access points. This is combined with [[CSMA/CA]] for multiple access within the cell.
* [[HIPERLAN/2]] wireless networks combine [[FDMA]] with dynamic TDMA, meaning that resource reservation is achieved by [[packet scheduling]].
* [[G.hn]], an [[ITU-T]] standard for high-speed networking over home wiring (power lines, phone lines and coaxial cables) employs a combination of TDMA, token passing and [[CSMA/CARP]] to allow multiple devices to share the medium.
