The role of an outdoor antenna for the LTE speed
It often happens that, despite very good LTE signal level, the transmission
speed is unsatisfactory. In this case, one should use an external antenna,
and direct it to another base station (often poor rates are associated with
a large number of users connected to a single base station).
Another way to increase the speed is to check whether the service provider
offers LTE-Advanced service in the area. Of course, the user has to be
equipped with a modem supporting this standard.
Sometimes there are problems with the LTE-A service associated with the
communication of the modem with an improper base station. Simply, the modem
communicates with the "strongest" base station that does not operate in LTE-
A standard. To solve this problem, the user should learn (from the operator)
where there is the nearest base station working in the LTE-A technology
with band aggregation (preferably located in the opposite direction to the
nearest/strongest base station that does not support LTE-A).
In the case study the user had been equipped with LTE-A modem but the
highest download speed was at the level of 10 Mbps and upload speed reached
only 1Mbps. The reason was that the modem communicated with base station not
supporting LTE-A standard. The situation is presented in the map below. |
