Stel provides fast and reliable internet wireless broadband connectivity ‌ wherever you are.
STEL is a Wireless Internet Service Provider. Our technology works on specific equipments designed to to guarantee a stable, reliable and fast connection.
The traditional broadband internet connectivity is provided through a fiber optic cable. Main advantages of this technology are the consistent reliability and the high level of performances even in critical conditions (huge number of users connected simultaneously).
The main disadvantages are the costs of the fiber optic and the installation (road excavations is always required). This expenses are so significant to limit the actual expansions of the broadband connectivity. That’s why to have a reasonable ROI the top players operating on the market are actually just covering the areas with an high population density. As a result a large part of the territory is not covered and it won’t even be in the next future.
On top of that even in the main cities it’s not uncommon to find areas that are not actually covered by fiber optic cables because of the installation problems we discussed in the previous chart. Here’s an example: Rome, Italy.
Yellow areas are fiber optics connected . Blue areas are connected with traditional Ethernet ADSL cables which determines, in most cases, a very bad performance service.
On the mobile side the major companies are expanding their networks to guarantee Internet Mobile Access which works perfectly for mobile devices but is not suitable for home and business use, as it’s not stable and too much affected by the number of users connected at the same time on each repeater.
This is what we call:
DIGITAL DIVIDE
An alternative solution to cover areas digitally divided is the Satellite Connectivity. No cables required, basic installation but… the average monthly rates are expensive , the signal is not stable as too much affected by weather conditions and by the number of users connected at the same time on a limited number of channels. Furthermore this system suffers problems due to a very bad latency (the amount of time it takes a packet to travel from source ,your pc, to destination ,satellites in the sky and being back “home”. We’re talking about 50.000 miles!!) Conclusions: it s’ good for emergency on isolated areas but not at all for a standard daily use.
The long distance terrestrial wireless approach is today the sole solution to efficiently cover areas that are actually digitally divided. The good news are that it does not require huge investments on the financial side but, on the other side, it has to be implemented by skilled companies which have acquired a long experience on installations and troubleshooting management. ‌ and this is what we do.
Ok, good, interesting but‌.how it works??
From a central point of distribution, which is connected to a “fiber optic access point” (provided by the wholesales divisions of International Carriers such as Mix Milan, Ams-ix Amsterdam etc) , we directly spread the wireless signal towards a network of radio repeaters. Each repeater can be used to “transport” the signal towards the next one (point to point) or to spread the signal towards a large number of local users (point to multipoint). Each repeater is practically a clone of the first one and so on The average distance among the repeaters is between10 to 15 miles. On a point to point connection it’s also possible to cover longer distances such as 20 to 30 miles.
Here ’s a simple example of a typical WISP scenario.
Here below is a real case history regarding one of the WISP networks that we own. The green dots indicates the radio repeaters which are actually active and the yellow dots the ones we’re going to install. More than 4500 clients are today connected on this network including public offices, factories, business offices, retail stores, private users, security web cam networks etc
In October 2014 STEL won the official tender launched by to assign and authorize the use of WLL frequency on the Sardegna territory for long distance internet wireless connection. Using the WLL frequency it is possible to guarantee an high performance service ( up to 500 Mbps ) in addition to all the advantages we indicated in the previous charts ( no excavations required, high speed connectivity, flexibility of the service and so on).
Sardegna
At the beginning of 2015 STEL has also signed an official agreement becoming “The Official Internet Broadband Provider� of Consorzio Costa Smeralda.
Here’s STEL actual coverage area on the northern Sardegna.
A wide range of standard contracts is today offered by STEL on the market. It is also possible to draw up specific customized contracts to increase the bandwidth service.
VOIP telephone service can also be provided as a separate service on all the areas actually covered, Sardegna included.
The entire network of repeaters and links is constantly monitored by specialists 24/7 within the control room to ensure a stable service. A control software is continuously checking and measuring the quality level of the signal, allowing immediate actions thanks to an automatic and redundancy backup system that is activated in case of any malfunction due to accidental causes.
