We squeeze out an Internet maximum of rural cells

2 years, 11 months ago
On the eve of New Year's holidays it was required to leave the capital a bit earlier, to leave it in the direction of such places in which the Internet happens quite seldom. For absence at work I promised workmates to be in touch. And as my kind of activity is directly connected with web, I decided to experiment with availability of the Internet in the planned place of stay.

Essence of a task was as follows:

  1. To reach the comfortable speed of the Internet.
  2. To distribute the Internet not only for itself, but also for the spouse.

We had 2 modems, 750 megabytes of the paid Internet, 3 notebooks, several phones and the whole set of sim cards of all sorts and coloring, access point with OpenWRT, usb hub, a flash card and the antenna. Not that it was the necessary stock for a trip, but if began to collect pieces of iron, it becomes difficult to stop. The only thing that caused in me concern - it is the antenna. Nothing in the world happens more helpless, irresponsible and weak, than the signal from the antenna which passed a cable through 3-meter usb. I knew that sooner or later we will pass also to this rubbish.

In 20 years of existence of IPv6 its support extended to 10% of devices

20 years ago, in December, 1995 the specification of the IPv6 protocol (RFC 1883) was published. The protocol was conceived as replacement for the IPv4 protocol existing up to that moment when it became clear that with acceleration of growth of the Internet and the devices of the IP address connected to it have to end quickly enough. 20 years later the IPv6 protocol 10% of all devices connected to the Internet use.

The statistics on use gathers the Google company – periodically at users of services of the company the script checking a possibility of loading of information through IPv6 is started. In particular it is known that in the working days the smaller number of users (8%) has an access to IPv6, than in days off (10%). Apparently, at house connections the situation is slightly better, than at workers.

Judging by the world map, distribution of access to the new protocol for the present very uneven. Green color means rather high percent of use of IPv6 (the USA – 24%, and the leader in this parameter, Belgium – 43%). Red and orange colors mean that users of IPv6 in these countries test delays in connection in comparison with IPv4.

In addition to smartphones, home electronics and wearable devices, Xiaomi (Xiao Mi, an accent on a final syllable) have also routers. Both small and budget, and big and rather expensive. Here about the last, with the built-in disk on the whole terabyte, the speech will also go. And still it is able to pretend to be Time Capsule for Mac.

Xiaomi Router 1TB (or 小米路由器硬盘版 1TB, or Xiaomi Router 2) is a house router with the built-in hard drive which can both distribute the Internet, and to execute functions of network storage (NAS), and also possesses the whole a lot of others useful and not really functions.

Stuffing at a router not weak.

73 Gbit / with — such is a new absolute record of data transmission rate under the TCP protocol

3 years ago
We welcome you on pages of the blog iCover! Promptly growing needs for transfer of large volumes of data – a sign tendency of our time and strong incentive for development of infrastructure of information networks. Along with expansion of geography of communications also the flow capacity of the main communication channels grows: 10 – gigabit network channels are replaced on 100 – gigabit. And here the question of efficiency of use of sharply increased potential of flow capacity of the channel faces restrictions of the existing data transmission technology of TCP (Transmission Control Protocol) which upper high-speed level was limited to record value of 29 Gbit / page until recently. The group of specialists from Japan managed to develop addition to the existing protocol which allowed to treble the existing value almost. The successful tests of technology which passed in November of this year confirmed a possibility of its application with use of the existing normal subscriber equipment.

The national commission of regulation of communication and informatization of Ukraine (NKRSI) suggested to fix legislatively a speed guarantee from the operator for subscriber connection. The guarantee provides that the speed of Internet connection of the client cannot fall lower than 70% from declared in the agreement. According to NKRSI, the similar initiative will allow to protect the rights of users, to increase quality of services in the market and to strengthen fight against so-called "gray" providers, writes "Business". Besides, clients are offered to oblige to give telecom operators an opportunity to control quality of services.

3 years ago

The Ministry of Internal Affairs does not want to look for owners of access points, access to which is possible without authorization (a photo: Sheets)

It is already necessary to pay for repeated violation more — from 200000 to 300000 rubles.

As envisioned by authors of the project, representatives of the Ministry of Internal Affairs have to control execution of the law. But in the department do not agree with such position, write "Sheets". The matter is that law enforcement authorities just will not have employees for such responsible mission — representatives of the Ministry of Internal Affairs speak about it.
