Hi.
Huawei B315 maxis 4G signal could be improved or not using this antenna?
for WIRELESS matter,
no one able to confirm you about 'how much', 'how changes' at real world BEFORE applying various wireless stuffs AT YOUR SITE, if one do tell u the result before any on site trial most probably juz dealer mouth of word for selling or amateur opinion or really a god can forsee anything.
wireless stuffs must be applied it in real world, at your place, then only u know. theory can be reference, but can not conclusive.
by theory, for sure external antenna ~ yagi type - higher dbi and directional type, perform far better compare to existing stock internal antenna - low dbi and omni type. so as long as for 2600mhz band usage, external yagi directonal antenna @ 18dbi works better in terms of either or combination of,
~ signal improvement
~ speed improvement (data flow increase due to higher signal reception & transmission)
~ stability improve (consistent connection, no drop out, or speed quite consistent)
~ lower latency (but this also affected by cable length of external antenna)
