    Sri Lanka Telecom Mobitel has signed a BOI agreement to trial and deploy a LTE (Long Term Evolution) Network for the first time in Sri Lanka. This will be part of the company’s network expansion project and will enable Mobitel to import/purchase (locally) project-related items free of customs duty.

    Mobitel has committed an investment of approximately US$ 60 million in its latest network expansion, adding 1,000 LTE capable radio base stations to the existing network infrastructure. With this, the company’s Investments committed to date in its LTE/3.5G/2.5G networks and service offerings amount to over US$ 400 mn.

    "Technology change is a key determinant of a country’s economic growth and therefore the introduction of LTE Network is expected to drive growth in the telecommunication sector as well as improve competitiveness and growth in several other economic sectors heavily depended on infocom" said, Jayampathi Bandaranayake, Chairman BOI of Sri Lanka. "We are happy to support Sri Lanka Telecom Mobitel in its endeavour to provide the latest ICT technologies which is sure to catalyze national development".

    LTE is the latest standard in the mobile network technology evolution after GSM/EDGE and 3.5G/HSPA network technologies, and Mobitel is gearing towards demonstrating broadband speeds nearing 100Mbps in downlink and 50Mbps in uplink, using this LTE technology when the spectrum is available.

    මෙක ගැනනම් දැන්ම කියන්න බැහැ.
    දැනට තියෙන HSPA පහසුකම් වලින්ම 20mbදෙන්න පුලුවන්

    When will TRC allocate the spectrums for 4G?
    Recently, in a news paper article, TRC said that they don't have any plans to allocate 4G spectrums until 2018, due to Television channel use the spectrums currently.
    So, until TV stations switch to T1 or T2 DVB, 4G is not possible.
    isn't it?

    නැහැ මචන් TV radio වලට තිබුණු ගැටළු විසදා ගත්තේ GSM එන්නත් කලින්ම තම
    ITU එකෙන්.අපිවයි, TV & Radio ලයි interfere වෙන්නේ නෑ දැන්.මෙතන කතා කරලා
    තිබුන ඒක එන්නෙත් 2.6Ghtz වලින්ම තම.ඒ නිසා ගැටළුවක් එන්නේ නෑ..ආවත් මේකට පාවිච්චි
    කරන්නේ උපරිම උනොත් bandwidth ඒක 20 නිසා ගැටළුවක් එන්නේ නෑ දැන් තියන transmitter එක්ක.
    TV ඉන්නේ අපිට ගොඩක් පහලින් එයාල 730 වගේ ඉවරයි.එතනින් එහාට ගියාට වැඩක් නෑ දුර පති වලට
    curvature effect කියන දේ ගන්න බහ frequency ඒක වැඩි නිසා.ඔය පත්තරේක එහෙම
    දැක්ක නම් ඒ බොරු කව්රු උනත් කියල තියෙන්නේ.

    අනික තම ලංකාවේ TRC මගුලෙන් නෙවේ ඔය spectrum ඒක තීරණය කරන්නේ.
    ITU එකෙන් කිව්වොත් මොන මගුලගේ එක තිබ්බත් ඒක දෙන්න වෙනවා..
