Deployed technologies

  Ajouter au panier

- All Internet technologies are deployed
throughout Normandy
- Traditional operators for broadband, WAP,
GPRS and UMTS.
- Alternative operators for wireless, cable,
satellite and PLC (PowerLine Communication)
technologies.



LOW THROUGHPUT

Low throughput concerns services provided by the commuted telephone network (CTN). Theoretical throughput is 56 Kbps.

BROADBAND (HIGH THROUGHPUT)

Generally refers to ADSL, ADSL 2+, SDSL and VDSL. Links the subscriber to the network via a telephone line.
- ADSL, throughput up to 8 Mbps
- ADSL 2+, 25 Mbps on download. 1 Mbps on upload.
- SDSL, symmetrical throughput from 144 Kbps to 2 Mbps.
- VDSL, up to 52 Mbps on download and 2 Mbps on upload.

Cable up to 2 Mbps on download and 700 Kbps on upload.
Optic fibre for consumers requiring very high throughput, such as major companies (several Gbps).
Powerline communication (PLC) on the electricity network, from 4 to 45 Mbps on symmetrical throughput.

WIRELESS TECHNOLOGY

In isolated zones:
- satellite, a few Mbps on download. Upload uses the CTN or satellite channel.
- the wireless local loop (WLL) which consists in connecting fixed telephony subscribers equipped with an antenna via the
hertzian network. Up to 155 Mbps in both directions
- WiFi, 11 symmetrical Mbps shared between users in a hotspot.
- WiMAX, approximately 70 Mbps.

NOMAD CONNECTIONS

Mobile phones and laptop computers linked via:
- Wap (Wireless Application Protocol): is a communication protocol enabling Internet access via a wireless transmission device (up to 9.6 Kbps)
- GPRS (General Packet Radio Service): mobile telephony standard (32.4 Kbps on reception and 19.2 Kbps on transmission)
- UMTS (Universal Mobile Telecommunications System) is one of Europe's third generation (3G) mobile telephony technologies (up to 2 Mbps).
