Application of SDMA

SDMA stands for space division multiple access. It depends on the user position information and provides users access to the communication channel based on their spatial locations. 

SDMA separated into the geographical space, where users are located, into smaller space. It is used for a mobile communication system which reuses the same set of cell phone frequencies in a given service area.


So compare to the other multiple access techniques like TDMA full form, CDMA full formFDMA full form, SDMA full form is compatible So it can be more used in a wireless communication system. This article gives the application about SDMA to know more details about SDMA.
  • Satellite communication
  • Optical communication
  • Wireless communication
  • Mobile communication
  • SDMA can be also used in conjunction with the WDM system  and TDM
  • SDMA uses a spot beam antenna

What is SDMA

For to know about SDMA you should first of all check it out the full form of SDMA.


SDMA stands for space division multiple access. It depends on the user position information and provides users access to the communication channel based on their spatial locations. 

SDMA separated into the geographical space, where users are located, into smaller space. It is used for a mobile communication system which reuses the same set of cell phone frequencies in a given service area.


Space division multiple access is techniques which are MIMO architecture and it can be used in wireless and satellite communication. This article also gives some feature of SDMA given below. 
  • SDMA is completely free from interference.
  • Controlling the medium access for a wireless network.
  • Careful choice of a zone for each transmitter.
  • In this system control the radiated energy for each user in space.
  • All user can communicate at the same time using the same channel.
  • The directional spot beam antennas are used and hence the (BS) base station in SDMA can track a moving user.
  • A single satellite can communicate with more satellites receivers of the same frequency. frequency.
  • SDMA never used isolation.

Advantages and disadvantages of SDMA

The term SDMA full form is Spatial Division Multiple Access OR Space Division Multiple Access methods. It is one type of channel access method. It is used for mobile communication system which reuses the same set of cell phone frequencies in a given service area. This article gives information about some advantages and disadvantages of SDMA to know more details about SDMA.

Advantages of SDMA :
  • SDMA is a purely optical path
  • SDMA is frequency reuse
  • Mobile station battery consumption is low
  • Increased spectral efficiency
  • SDMA is transparent to the system if it is purely optical
  • Use any bandwidth or data rate achievable in fiber
  • SDMA is usually combined with other multiplexing techniques to better utilize the individual physical channel
Disadvantages of SDMA :
  • Some of  the disadvantages of  SDMA is the fact that the number of switches
  • SDMA is very expensive and complected to construct and design
  • There are also high insertion losses since each input must have the capability to be split to any output.
  • The reverse link may be a problem like an interference problem

SDMA definition

SDMA full form stands for spatial division multiple access or space division multiple access methods. It is one types of multiple access methods. It is used for a mobile communication system which reuses the same set of cell phone frequencies in a given service area. A base station, SDMA continually adapts to the radio environment. Some feature of the SDMA method given below :
  • SDMA become less practical.
  • SDMA is suited for short distance transmission.
  • In SDMA single fiber replaced with multiple fibers used in parallel.
