There are two main types of Cellular phone com usage, that being CMDA and GSM. GSM operates, typically in a range of 850mhz, 900mhz, 1800 and 1900mhz. In parts of Europe it also uses 2100mhz. Older GMS specs can go as low as 380mhz for uplink and downlink and the channel will vary. CDMA operates at usually at 800mhz or 1900mhz. Some of the 4g WiMax signals can run as high as 2.7ghz. That however is used for data, not for voice mode. Again, different variations of this will run at other speeds but those are the most common ones.
800mhz
yes
800MHz and DDR2 is the assigned DIMM
It is a type of system memory, called RAM (Random Access Memory) Kingston is the manufacturer, or brand Valueram is the product line, or model 2 GB means 'Two Gigabytes', or 2,048 megabytes 800 MHz is the RAM's speed. DDR2 is the technology, 'Double Data Rate 2'. PC2-6400 is a way of repeating speed, type, and tech. PC2 means 'DDR2' and -6400 is the speed (6400 MB/s, or 800 MHz. 100 MHz = 800 MB/s for DDR2) CL5 is the 'CAS latency'. This is how quickly the ram responds. It is a second method of measuring speed. The frequency (800 MHz) is the 'top speed', while the CAS latency is the 'acceleration'. What this means is that the computer needs 5 cycles to prepare every read or write, before it begins to do so (at 6400 MB/s). Lower CAS latency means faster response time. Generally, the frequency (MHz) is more important than CAS. But if you have two types of RAM with different CL and the same frequency (MHz), the one with the lower CL will be faster. CL5 and CL6 are standard DDR2 speeds. CL5 is considered 'good'.
yes if you have a celeron CPU you can upgrade to highter rated celeron's but to a max of 667mhz bus speeds. as for c2d CPU's again providing you keep with the 667mhz bus range the sky is the limit ! mine was a t2700 which i upgraded to a t7600 ! i have also upgraded my memory from 1gig 800mhz to 4gig 800mhz bios sees new CPU and memory correctly and set them correctly
The GPRS is running at 800Mhz in Europe while In US, it is running at 1900Mhz.
800mhz is a frequency, not a measure of wattage. The two are not related.
The term "Mhz" stands for Megahertz, where hertz is the number of cycles per second, and Mega equals 1 000 000 (one million). Therefore, 800Mhz is 800x1000 cycles per second. The term Mhz is commonly applied in computers. For example, a 800Mhz Processor has 800 000 cycles/second and this is its computing speed.. In comparison, a common 2.3Ghz processor is much faster because it has 2 300 000 cycles/second.
CDMA network work on 800MHz and 1.8GHz frequency. ankush agrawal
Yes, it is backward compatible
1600 Mhz, 1333Mhz, 1066Mhz, and 800Mhz
It's limited by your motherboard on what CPU it can take. The list of supported processors is most likely listed in the manual.
