Ofcourse BW will play its own role. But, present situation limitation of ADC speed, signal processing chip speed limitation and high data rate modem implementation complexity will play the major role.
In future, if any one invent modulation with magnetic force, it may be possible.

What is stm 4 bandwidth?
Hai, first STM stands for (Synchronous Transport Modules) it is nothing but the bandwidth Throughput, STM1 = 155.52Mbps there for for STM4 = STM1 * 4 ie = 155.52 * 4, there fore STM4 = 622Mbps, Thanks & Regards Ashok Sriram DEN NETWORKS BANGALORE
How many DS3 in STM1?
3 ds3 in stm1
How many e1s make STM1?
63 E1
How many E1 in STM-4?
1E1=2.048MbpsSTM1=63 E1...AND STM4=4*STM1=63*4E1sbUT ITS NOT THAT EASY...In SDH there is a lot of header data...STM1 =155.52MbpsSTM4=622.08MbpsSTM16=2488MbpsSTM64=9953Mbps....

What is stm1?
STM-1 stands for Synchronous Transport Module level-1....:)
What guitar does Sam Totman use?
He uses the Ibanez STM1 in white and black color. And he uses an STM2 in color blue.
How many mbps does an stm1 has?
in GE interface the STM-1 can carry 155 Mbps but on SDH it will carry 142 Mbps
What is short haul and long haul in stm1 surpass?
short haul in stm1 is below 30km and long haul which works for more then 30km.. there are differenet equipments for short haul and long haul.. working different wavelenght. long haul can work one 1310 nm and 1550nm.. but short haul can work on 1310 nm only..
Have a confusion that one STM1 has 63 E1. Size of E1 is 2.048Mbps. then size of one STM1 should be equals 63x2.048 equals 129.024Mbps. but in real STM1 is 155Mbps?
E1 is carried inside C-12 container in SDH enviroment. Size of container is bigger than payload requirment of E1 in order to have clock alignment, justification opportunity bits, justification control bits, & overhead bits. C-12 container is 272 bits which multplies with 8000 (frames per second) to get data rate for one C-12 per second. Multiplying it with 63 will give you 137.088 Mbps.
Why 63 E1 is equal to STM1?
It's not.-- The E1 line rate is 2.048 Mb/s.-- The data rate of 63 E1s, simply time multiplexed, would be 63 x 2.048 = 129.024 Mb/s-- 64 E1s may be multiplexed into a single E4 stream, at a rate of 139.264 Mb/s.-- The STM1 data rate is 155.52 Mb/s. Any combination of data streams totalingroughly that rate, including as many as perhaps 75 E1s, could be packaged fortransport on an STM1 facility.
Difference between SDH and PDH stransmission?
SDH and PDH are two digital hierarchies in which different line speeds (e.g. E1, T1, STM1) are categorized.PDH (plesiosynchronous digital hierarchy) was replaced by SDH (synchronous digital hierarchy) due to its drawback in synchronisation where plesio refers to nearlysynchronous.E1, T1 and J1 are generally categorized under PDH. STM1, OC3, STM4, OC12 etc. are categorized under SDH.E1 is used worldwide nowadays in 2G technologies except North America and Japan (who are using T1 and J1 respectively). It is the line speed of 2Mbps. But how this speed comes along? The derivation is as follows.The audio signals were sampled and converted to digital signal at 64kbps, since 1960s for digital transmission of voice calls. When 32 channels (30 assigned for voice channels and 2 channels for framing and signaling), with each having speed of 64kbps are put together (or we call multiplexing), a line speed of E1, i.e. 2Mbps is produced by having 32 x 64kbps = 2.048Mbps.T1 line, which transmits at 1.544 Mbps can be interconnected with E1 for international use.Having 3 different speeds (E1, T1 and J1), PDH was later replaced by SDH in order to standardize the speed, making only 1 standard speed worldwide, which is STM1 having the speed of 155.52Mbps.
