Survey Lang po! about wimax signal! :)

  1. naeexpercience po ba to! sa kabilang furom po nangaling to..delete kung bawal!

    To know more about wimax signal

    How to track BTS/BSID or Base Station ID or Globe Tower

    This tutorial is how to tune your antenna on the right path according on the available BTS in your area, for signal strength effectiveness.
    "DIY, rather than waiting for a globe technician to do it"
    - tagal nila dumating ska gagawin lng nilang 100% signal mo pero di mo makukuha full potential ng Internet mo, specially when it comes w/ ur registered DL rate (at least)


    * Basa basa lng po bka makatulong at may matutununan.
    * Applicable to legit and non-legit users

    Additional information:
    4G data networks using Long Term Evolution (LTE) or WiMAX (Worldwide Interoperability for Microwave Access) is a wireless communications standard designed to provide 30 to 40 megabit-per-second data rates, providing up to 1 Gbit/s for fixed stations. It is a part of a “fourth generation,” or 4G, of wireless-communication technology. WiMax far surpasses the 30-meter (100-foot) wireless range of a conventional Wi-Fi local area network, offering a metropolitan area network with a signal radius of about 50 km (30 miles)

    3G networks that descended from GSM. 3GPP technologies evolved as follows.
    • General Packet Radio Service (GPRS) offered speeds up to 114 Kbps.
    • Enhanced Data Rates for Global Evolution (EDGE) reached up to 384 Kbps.
    • UMTS Wideband CDMA (WCDMA) offered downlink speeds up to 1.92 Mbps.
    • High Speed Downlink Packet Access (HSDPA) boosted the downlink to 14Mbps.

    Ano ba ang basehan mo para s malakas at stable ang connection?!

    CINR
    CINR stands for Carrier to Interference-plus-Noise Ratio (CINR), expressed in decibels (dBs). CINR is a measurement of signal effectiveness. We use the CINR score to tell us the signal quality received by the modem.

    The higher the number the better signal quality you are receiving. You need at minimum a CINR of 8 or greater to receive consistent service. A CINR score of 18 or higher is considered excellent signal quality.

    RSSI
    RSSI stands for Received signal strength indicator RSSI is a measurement of the power present in a received radio signal. We use RSSI score to tell us the strength of signal your modem is receiving.

    A RSSI score of -100dBm reflects poor signal strength, a score of -50dBm is an excellent RSSI score and reflects a strong signal.

    RSSI = received signal strength indicator
    which is basically "level of received signal" strength in dBm

    CINR = Carrier to Interference+Noise Ratio
    which is basically "signal to noise ratio" in dB
    RSSI from -50 to -85 dBm
    -- you want RSSI to be closer to -50 than to -85

    CINR from 10 to 30 dB
    -- you want CINR to be closer to 30 than to 10dB
    -- any value of 20 or more can be considered a "good signal"
    -- any value of 15 or less will probably trigger your modem to try to swap to another tower

    1Mbps connection with RSSI of -79.50 and CINR of 12.56 is marginal.

    * di po basehan na bsta 100% signal ka para good connection


    *** This certain value is referring to DL rate or speed test not IDM rate and if you've able to acquired quality signal this would be the value you will get.

    QPSK 1/2 - 1kbps to 2mbps
    QPSK 3/4 - 2 to 3mbps (most often sa non peak hours specially sa madaling araw, if peak hours 500kbps to 2mbps)
    16-QAM(CTC)1/2 - based on my experience (1mbps) ms pipiliin q pa mkakuha ng QPSK 3/4 (cguro ms benefit dito ung "VIP" MAC)
    16-QAM(CTC)3/4 - 4-6mbps ("VIP" MAC will get this dl rate)
    64-QAM(CTC)1/2, 2/3 or 3/4 - 6-12mbps ("VIP" MAC will get this dl rate)
