Last Mile – what is this? The term last mile in the telecom and internet industry describes the last part of the telecom network. The part of the provider’s network, which is closest to the customer. In this article you could check the ten types of the last mile connections.
Ten Types of Last Mile Connections
1. LAN – Local Area Network
Traditional LAN systems use wires. You can find three types of LAN cables:
- UTP electrical cables
- Optical cables
- Coaxial cable
The use of the coaxial cables in LAN network is outdated.
2. Wireless Network
Wireless networks don’t require any wires. The most popular wireless technologies today are:
3. DSL – Digital Subscriber Line
DSL technology offers fast speed data transfer on the existing legacy telephony infrastructure. On the same line there could be a telephony signal for voice and DSL for data.

4. CATV – Cable
CATV – Community Access Cable Television Systems is usually called a cable. The cable supports TV communications at the same time with the Internet access. It has problems with the limited S/N. The periodical use of the amplifiers solves the problem of low signal-to-noise ratio.
5. Fiber optics
The fiber optics has the largest capacity of all last mile technologies. The problem with the fiber optics is the relatively high price.
6. Satellite Technology
Satellite technology has relatively high capacity, but it is quite expensive. It is the best solution for the isolated areas. More about the technology read on Satellite Internet Providers.
7. FSO – Free-space optical communication
Free-space optical communication technology is based on the propagation of lightwaves in free space. Free space means the vacuum, outer space or air. The technology uses visible and infrared light. It works on a lower frequency than the radio waves. Physical obstructions and a weather conditions like fog and rain have a big impact on quality of the lightwave signals.
The technology is used in the following scenarios:
- In space communications between spacecraft
- LAN-to-LAN connections
- Inter and intra chip communication
- Backup for fiber optics
8. Radio waves
The radio wave technology uses longer wavelengths than a lightwaves. It has a lower attenuation and higher data capacity. The most popular use of the radio waves is in radio and television broadcasting and cellular communications.
9. Telephone System – POTS
POTS – Plain old telephone system is the classical telephone service. It is based on analog signal. It can be used for voice and for data communications with analog modems. The voice and data can’t work at the same time, like with DSL.
10. ISDN – Integrated Services Digital Network
ISDN is a newer telephony technology. It works with digital signals so voice and data can work in the same time. The problem is that when you receive a voice call, you lose half of the speed for data.
