V n\u011bkter\u00fdch p\u0159\u00edpadech jsou u\u017eivatel\u00e9 nuceni spokojit se s p\u0159ipojen\u00edm zalo\u017een\u00fdm na ADSL, s odpov\u00eddaj\u00edc\u00ed rychlost\u00ed a mo\u017enostmi.

Pokud jde o za\u0159\u00edzen\u00ed \u2013 mo\u017enosti jsou zat\u00edm velmi skromn\u00e9.

Stoj\u00ed za zm\u00ednku i monopoln\u00ed postaven\u00ed na trhu. Pokud je v cel\u00e9m okol\u00ed jedin\u00fd poskytovatel Internetu, m\u016f\u017ee diktovat nejen ceny, ale i \u00farove\u0148 slu\u017eeb.

LTE3301-M209 router comes with external antennas for receiving the signal from the base station. Additionally, the presence of 2 SMA-F connectors allows for the connection of powerful external LTE antennas for a reliable connection even in areas where the cellular signal is weak.<\/p>\n

When a bunch of cutting-edge electronics such as mobile gadgets and high-end laptops move to the summer house or office, it's better to choose the latest models that support the newest options for Wi-Fi access, LTE, and other useful features.<\/p>\n

<\/p>\n

If there is an option for outdoor placement, consider the LTE7460-M608 model. (See Figure 2).<\/p>\n

<\/p>\n

Firstly, you can place the LTE router in an area with better reception, such as under the roof, outside the building, and so on.<\/p>\n

<\/p>\n

Secondly, this location allows for reliable Wi-Fi connectivity not only inside the building but also in the open area of the property. The LTE7460-M608 model uses built-in antennas with a gain of 8 dBi for connectivity. Another important feature is that power over PoE allows placement up to 100 meters from the house, on a roof or pole. This is especially relevant when tall trees near the house may obstruct the cellular signal from the base station. The LTE7460-M608 comes with a PoE injector that provides PoE+ power up to 30 Watts.<\/p>\n

<\/p>\n

However, sometimes using an outdoor device is not possible due to various circumstances. In this case, the gigabit LTE Cat.6 Wi-Fi router AC1200 with FXS port (model LTE3316-M604) comes to the rescue. This device has four GbE RJ-45 LAN ports. An important point is that the first port LAN1 can be reconfigured as WAN. This results in a versatile device that can be used as a regular router for connecting to the provider via twisted pair in the cold months, and in the summer as an LTE router. Besides the financial benefit of buying one device instead of two, using the LTE3316-M604 allows for no need to reconfigure parameters for the local network, access settings, and so on. The only thing required is to switch the router to use a different external channel.<\/p>\n
