1. You can keep up with the latest information on the daily coin website, bitcoin forum and the candy channel of telegram.
2. Can go to try, ECEX platform operation is relatively simple, novice can also play
3. EC is the platform token of project echoin, with a total circulation of 2 billion EC. It was launched on the exchange on August 8, 2019. At present, three exchanges have been launched. According to the information I have inquired, it is said that it is a digital currency focusing on energy technology, such as blockchain. Please be careful about digital currency.
4. RSCP (received signal code power) is translated as received signal code power (commonly known as level value). It refers to the power of a signal number received on physical channels such as DPCH, PRACH or Pusch
rsrp (reference signal receiving power) is one of the key parameters and physical layer measurement requirements in LTE network, which can represent the wireless signal strength. It is the average value of signal power received on all re (resource particles) carrying the reference signal in a symbol
to put it simply, RSCP generally appears in TD and rsrp in LTE. The physical resources of 3G and 4G are different. The smallest resource unit carrying TD channel is bru, and the resource unit carrying 4G channel is re; The connection is that TD and TD-LTE are both TDD technologies, using TDD full plex.

5.
E is the abbreviation of energy, C is chip, which refers to the chip in 3.84 MCPs, EC is the average energy of a chip, note that it is energy, and its unit is Joule
6. It reflects the interference level of the system and is related to the load of the system. It measures downlink coverage and is an important criterion of handoff algorithm. It can be directly measured by UE without despreading,
in engineering, WCDMA scanner can be used to measure EC / io of each cell, so as to optimize and adjust the relationship between adjacent cells. The transmit power of pilot is usually set, and the value of EC is affected by fading and changes with time and position. IO is the total power of broadband received by downlink UE, including EC itself. This is why EC / IO (equivalent to the familiar C / (C I), rather than the signal to interference ratio C / I) is always negative dB, and the signal to interference ratio has a wider range. When the system load is fixed, the value of IO is relatively stable or changes gently, while the value of EC changes rapidly with the wireless environment. Comparatively speaking, the change of their ratio EC / IO is slower than that of EC itself
EC / no is the ratio of chip energy to total interference energy density, which is channel dependent. Note that energy density no is sometimes called NT. For pilot channel, it is the ratio of chip energy and total interference energy density of downlink pilot channel. For traffic channel, it is the ratio of chip energy to total interference energy density. EC / no can also be measured directly without despreading, and its physical meaning is equivalent to the familiar signal to interference ratio C / I
the difference between IO and no is ignored. EC / no is defined in 3GPP, while EC / iomscbs is used by many manufacturers in air interface
2. EC / IO is an index to measure the quality of forward (downlink) signals in CDMA2000 or WCDMA.

7. The minimum value of EC / IO is - 15dB because of T_ The default threshold of drop is - 15dB. At the same time, in the rural scene, when there is only one signal coverage, the call can be normal at this value
the limit of the maximum value of EC / IO is - 1dB, because IO is the sum of signal and interference (it is wrong to say that IO is the sum of interference of other cells in some principle books, that is, O identifies other)
EC is chip energy, IO is the total power received by the mobile phone, including noise and useful information. EC / IO is usually used to represent the quality of the pilot channel, because the pilot channel has no bit information, and the quality of the pilot channel is the forward coverage quality of the corresponding sector. It is similar to the relationship between carrier to interference ratio:
EC / Io and C / I:
C and EC: C is the carrier power, EC is the chip energy, and the relationship between them is: C = w * EC. W is the chip rate
I and IO: I are the total interference power (including thermal noise), and IO is the interference spectral density (including thermal noise). The relationship between them is I = w * IO,
so EC / Io = C / I.

8. EC / Io: e is the abbreviation of energy,
9. That's the eco pass. It's still an unknown number. It's made by the 99 community! As for its future, it is a digital currency that needs a lot of money to support the bottom! Look down!
