Somehow unnoticed on soft paws, it's time to high speeds and low tariffs for Internet access.Now nobody will be surprised access to the global network at speeds of over 100 megabits, especially in large cities.However, all this is done with the help of wires: optic or conventional wiring harness - the essence is the same.But the inhabitants of remote areas of the town and villages where there are no providers of cable lines to connect to the Internet to be content with the proposals wireless operators.Their rates are much higher and the lower speed.For example, one of the most modern technologies CDMA Rev.B theoretically allows access speeds up to 14 megabits of all that citizens - "yesterday."It is clear that in such conditions, each user of the wireless Internet would like to know how to increase the speed of 3G modem.
That's what we will talk today, but as an example, consider CDMA EVDO modems.Although there are several modifications CDMA, different, first of all, carrier frequency, referred to in this paper, based on the approach for any user who wants to increase the speed of 3G modem.
Anticipating the questions, a little touch on the theoretical foundations.Firstly, any payment provider herein indicates the speed of access to the network, for example, up to 3.1 Mb / s.Users first connect to the wireless Internet often wonder why not that of 3.1, but even 2 megabit possible to achieve extremely rare.No deception: the prefix "Up" is fully justified, alas.However, nothing prevents to understand the issue and understand how to increase the speed of 3G modem to the maximum possible, the more that can do it to anyone who is given such a purpose.
Secondly, the speed of the wireless Internet will never be stable: it "floats" from hour to hour.Each tower station has its own fixed-rate communication channel, although quite large.Subscribers connected at a given time, this rate is divided between them like an orange.Accordingly, the first answer to the question of how to increase the speed of 3G modem, is to use the CDMA modem in the coverage area of the least loaded station at the right time.In other words, the rate will be higher in areas with low population density three in the morning than in the middle of a large city in the business time.
Well, leave alone the theory and indicate what and where you need to "tweak" to achieve outstanding results.How to speed up 3G modem?Just!It is noted that the different models show different speed modems, ceteris paribus.The implementation of a transceiver unit, ergonomic placement of internal components greatly influence the result.For example, some models after 2-3 hours of operation considerably heats up and begins to fail, it immediately noticeable on the chart speed.Check the modem - it should be warm but not hot.
Any USB 3G modem consumes a certain current from the port.Moreover, it is usually 500 mA.For the USB 2.0 standard is just and there is a limit.Therefore, if one USB hub connected to the modem and any other device, the power is not enough, that the impact on the work.You have occupied more than half of connectors USB?In that case, you need to purchase a hub-hub with an external power supply.Alternatively: is it permissible to connect the modem via the Y-cable.He has three ends, two connectors are included in the computer, and the third goes to the modem.
If you still do not understand how to increase the speed of 3G modem, the act radically: install an outdoor antenna.The height at which it is possible to raise the limits cable - its length should not exceed 10 m. The cable is not worth saving, buying quality!By the way, do not forget to align the antenna to the base station.
also useful to update the modem driver and optimize the connection of special software.
