Expansion Of The Existing Network

    DCS1800 base value of existence is to divert traffic and solve the GSM900 frequency interference problems, but DCS1800 feeder loss, wave propagation attenuation, obstruction losses are greater than GSM900. Under the same conditions, DCS1800 base stations to cover more difficult than the GSM900 serious interior and other regional blocks, DCS base station traffic diversion effect is very limited.

    In the densely populated high traffic urban areas, GSM900 base station carrier frequency as a result of expansion of the frequency resource-constrained interference occurs. Replace DCS1800 base station resolves the expansion pressure, but a marked contraction of the coverage area. The installation of DCS1800 base stations in the new multi-carrier amplifier MCPA can improve signal strength, while addressing the traffic is more difficult to take into account the high and weak coverage problems.
