A possibility to put the SIM card of mobile operators or the USB Dongle adapter in the router providing access to the 3G mobile Internet.

Prior to buying a router with the 3G support you should verify whether the device supports the 3G USB Dongle receiver of the particular mobile communications operator at the manufacturer's website.

SingleBand is a standard wireless technology characteristic of all the modern wireless devices.

DualBand is 2.4GHz with an additional 5.0GHz channel providing better receiving of the signal and more stable high-speed operation. For using this function both devices, i.e. the router and the wireless network card, have to support the DualBand mode.

LAN or ethernet cables connection slots operational mode.

10/100 MB.s is the standard speed characteristic of almost all the routers.

10/100/1000 MB.s, or GigaBit is tens of times faster standard which, in combination of GigaBit LAN network cards, provides great data transmission speed advantages between computers connected within the internal network. This solution is usually required in offices where large data volumes are copied between computers or fast Internet connection is used (no ~30 MB/s) simultaneously in several computers.

A possibility to connect a printer to the device via the USB port and to share it within the internal network. This function operates only with the printers that support a PCL printing language. HostBased printers that prepare the image in the computer will not be able to produce print-outs from this device.

It should also be taken into account that the majority of printers are multifunctional devices with fax and scanner options. Due to the heterogeneous technologies PrintServer devices in most cases do not support the scanning function.

Wireless transmission technology standard.

802.11G is an obsolete standard and supports only the 54MB/s data bandwidth which is often too low nowadays.

802.11N is currently the most popular standard, however the high-speed possibilities of this standard differ. It is advisable to choose a device that provides the 300MB/s bandwidth because currently it is the optimum purchase providing for a certain reserve for future needs.

Access Point - bezvadu piekļuves punkts, kas nodrošina kabeļu tīkla paplašināšanas pārraidi bezvadu tīklā izmantojot vienu LAN pieslēgvietu. Access point nav rūteris, un nespēj sadalīt vienu interneta pieslēguma adresi vairākiem datoriem, tamdēļ šo iekārtu slēdziet tikai aiz esoša kabeļu rūtera.

Router, jeb maršrutētājs - bezvadu piekļuves punkts, kas nodrošina viena interneta pieslēguma sadalīšanu vairākiem datoriem, gan caur tīkla vadiem, gan bezvadu tīklā. Parasti bezvadu maršrutētājam ir viena kabeļu interneta pieslēgvieta, četras datoru pieslēgvietas (kuras var papildināt, izmantojot switch komutatoru) un antenas, kas nodrošina apraidi datoriem un citām WiFi iekārtām.

Range Extender - bezvadu tīkla apraides attāluma pastiprinātājs. Paredzēts esoša signāla pastiprināšanai, lai palielinātu uzveršanas un pārraides attālumu.

Wifi adapter - Bezvadu tīkla karte, paredzēta datora pieslēgšanai pie bezvadu WiFi rūtera vai piekļuves punkta. PCI, PCI-E ir paredzēti galddatoriem, savukārt PCMCIA un USB - portatīvajiem datoriem. Jāpiebilst, ka lielākā daļa portatīvo datoru jau rūpnīcā tiek komplektēti ar bezvadu tīkla kartēm.

USB tīkla karte ir pēdējā izvēle, jo USB2.0 caurlaidības ātrums ir samērā zems ~22MB/s, kas nozīmē to, ka netiks izmantots bezvadu tīkla maksimālais iespējamais ātrums. Ja ir iespēja, labāk izvēlēties kādu citu pieslēguma veidu.

VPN or the Virtual Private Network is the ability of the device to form an encoded local network within the Internet based upon its processing resources. If a company has several offices that are mutually connected via the public Internet connection the VPN allows to create an artificial internal network that will not be "visible" to the other Internet users, however, the company staff will "see" this network as a usual Workgroup network of common use.

VPN funkcija prasa samērā lielus skaitļošnas resursus, tamdēļ datu pārsūtīšana būs lēnāka, nekā ierasts parastā iekšējā tīklā LAN.
