What is the difference between time division multiplexing and space division multiplexing?
The difference is the way the data is separated and transmitted between two points.
In Space Division the data is separated physically i.e. the carrier medium is divided into different channels. This could be by using different wires, waveguides, optical cables, etc, or by frequency i.e. radio channel, carrier frequency.
Time Division uses the same channel in one of the above but different data is given a specific order and location in time for transmission.
e.g. Synchronsation followed by type (a) data, then type (b) data followed by a checksum. The whole process is repeated continuously until transfer is complete.

What is 3 c and 7 c difference between?
3.5 and a space :)
Difference between continuous and contiguous?
contiguous is "separated in space" and continuous is "separated in time"
What is the difference between laminated and prismatic battery?
What is the difference between cylindrical and prismatic battery cells?
What is the difference between long radius and short radius bend in oil and gas pipes?
The difference between the 2 is length and curvature. A short radius elbow offers a tighter turn than the long radius. The short radius elbow is cheaper and will fit into a tighter space.
Advantages of space division switching over time division switching?
Space division multiplexing uses spacing to separate channels in a communications link. These separations may be done by frequency, insulation, or distance (spacing). Time division multiplexing is one way of doing the spacing separation. Space division multiplexing may use other techniques, such as TDM, FDM, etc., to maintain separation so that the conversations do not collide with each other.
What is space division multiplexing?
A road of meters wild, we devide it to 2x2, 2m for coming cars, 2 for going. that's a space mux. translate that into bandwith mode. total bw is divided to parts, each part for a user for example, that's a space mux
How is SDM typically realized and combimed with FDM?
Statistical Division Multiplexing (SDM) is typically realized by allocating time slots to different users based on statistical multiplexing techniques. This allows for more efficient use of available bandwidth by dynamically assigning resources based on user demand. When combined with Frequency Division Multiplexing (FDM), SDM can further increase the overall capacity of a communication system by simultaneously multiplexing signals in both the time and frequency domains. This combination enables even greater flexibility and efficiency in managing multiple users and their data streams within a shared communication channel.
Why does ice have a difference difference density than liquid water?
It has a different amount of space between molecules.
Difference between multiplexing and multiple access techniques?
Multiplexing and multiple accessModern telephone networks allow bandwidths in their channels that are much larger than those is needed for a digitalized telephone channel. Basically, a number of channels share a common transmission medium with the aim of reducing costs and complexity in the network. Multiplexing is defined as the process by which several signals from different channels share a channel with greater capacity. When the sharing is carried out with respect to a remote resource, such as a satellite, this is referred to as multiple access rather than multiplexing. There are various ways of performing this sharing:# FDM/FDMA (Frequency Division Multiplexing/Frequency Division Multiple Access): Assigns a portion of the total bandwidth to each of the channels. # TDM/TDMA (Time Division Multiplexing/Time Division Multiple Access): Assigns all of the transport capacity sequentially to each of the channels. # CDMA (Code Division Multiplexing Access): In certain circumstances it is possible to transmit multiple signals in the same frequency and at the same time, with the receiver being responsible for separating them. This technique has been used for years in military technology, and is based on extending the spectrum of the signal and reducing the transmission power. # PDMA (Polarization Division Multiple Access): Given that polarization can be maintained, the polarization direction can be used as a multiple access technique, although when there are many obstacles noise can make it unsuitable, which is why it is not usually used in indoor installations. Outside, however, it is widely used to increase transmission rates in installations that use microwaves. # SDMA (Space Division Multiple Access): With directional aerials, the same frequency can be re-used provided the alignment of the aerials is correctly adjusted. There is a great deal of interference but this system lets frequencies obtain a high degree of reusability.
The is the vertical distance between two points?
In 2-dimensional space, it is the difference between their y-coordinates, in 3-dimensional space, it is the difference between their z-coordinates.
What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What is meant by space?
Space is the measurable distance between "solid" objects. It can also be a temporal difference, like the space between breaths or the space between one's first and second marriage.
