As the frequency increase its penetration power decreases.The signal travels a lesser distance.Hence for a perticular area more no of towers need to be erected in 1800/1900 than in 900MHZ for full coverage...Hence vodafone( 1800MHZ) has more towers per unit area than Idea Cellular ( 1800+900) .....
Band of 900 is from 890-915( uplink) 935-960Mhz( downlink)....
Band of 1800 is from 1710-1785(uplink) and 1805-1880MHZ(Downlink)....
Same property is followed here.....The uplink is lower ( MOBILE -BTS) than the downlink frequency (BTS-MOBILE)...so that this may help the uplink signal to travel futher without consuming much power...BTS due to its increased power ,has higher frequency to tavel the same distance....

What is 200KQ7W emission?
200KQ7W is the emission bandwidth of GSM 900/1800 network. 200K - 200KHz bandwidth Q - The carrier is angle-modulated during the period of the pulse 7 - Two or more channels containing quantized or digital information. W - Information to be transmitted- telegraphy, facsimile,telemetry, data transmission, telephony and television(video)
What will be the torque of motor 7.5HP and RPM 900?
43.7667 ft•lb
A generator produces 240volts at 25 amperes. If the mechanical and electrical power losses total 900 watts what is the efficiency of the generator?
Efficiency is measured as the ratio of power output to power input. In this case the power input of the generator is 240V * 25A = 6000 VA however the stated losses are 900 W so the power output is 6000 - 900 = 5100W. Then the efficiency would be 5100/6000 = 0.85 or 85% efficient.
What is gsm uplink?
Hi, For every GSM band there are Uplink and downlink frequencies. Example: GSM 900 TX: 880 MHz to 915 MHz is an uplink frequency range GSM 900 RX: 925 MHz to 960 MHz is a downlink frequency range Aloha, Maverick
What heat does an electric soldering iron reach?

Can the touch dual work in the US?
as long as it is tri band on the box it will usually state the frequencys 900/1800/1900 you want 1900 for the U.S
What are the differences between dual band and quad band phones?
Basically, the difference lie on the frequency being used or supported. For GSM dual band phones, the frequencies that is can support are 900/1800 MHz or 850/1900 MHz; for tri-band phones, the frequencies are 850/1900/2100 or 850/1700/2100 or 900/1900/2100 MHz or 900/AWS/2100; and for quad-band phones, the frequencies are 850 / 900 / 1800 / 1900
If gsm 900 is superior than gsm 1800 than why do 3G uses 2100mhz?
Not all 3G networks use 2100 MHz, only 3G in Japan and South Korea does. The higher you go in GSM, the more superior the results, which means a GSM 1800 is better than a GSM 900.

What kind of angle is 150?
Angles less than 900 are called acute angles. 900 angles are called right angles. Angles that are greater than 900 and less than 1800 are called obtuse angles. 1800 angles are called straight angles. Anles greater than 1800 and less than 3600 are called reflex angles. 3600 angles are called full rotations. 1500 is therefore an obtuse angle.
