In the era of rapid development of science and technology, see how the Internet bigwigs respond. At present, Craig Barratt, head of Google's optical fiber project, has stepped down and laid off his staff to suspend the promotion plan in 10 cities. Webpass has been hoping to introduce wireless technology to continue to promote home and business high-speed Internet access plans. An unrealistic problem

Google hopes to increase its search, advertising and other Internet business revenue by promoting high-speed Google optical fiber, while seeking government subsidies to reduce the cost of optical fiber. At that time, Google launched the Gigabit broadband service monthly broadband subscription fee of only 70 US dollars, but also provide low-speed free broadband services, while the largest US Verizon fiber broadband FiOS lower 50 Mbit / s broadband month also 76 US dollars, which A plan for the then telecom operators have a serious impact.

In the first few years, Google added Google optical fiber coverage cities every year to counter the fact that all parties questioned it, so Google Optical Fiber program has gradually won the public recognition. However, with the increase of users, its costs have started to increase, and government subsidies can not be provided for a long period of time, and problems are gradually starting to emerge.

We all know that high-speed fiber optic home or business, need a very strong transmission network to do the support, but also to build a strong data center, etc., all this requires funding, but also the cost of optical fiber broadband, but in the early When Google users are less, the cost of paying through the network of leased telcos is within Google's affordable range, and some of the costs are made up by getting government subsidies.

However, after the rapid expansion of subscriber base and the competition with telecom operators, it is certainly impossible for telecom operators to lease broadband to Google at a discounted price. If Google invests its own fiber transmission network, it will require substantial investment, and The construction period is very long, this from China Mobile since 2010 crazy construction of optical fiber transmission network but so far failed to keep up with Telecom and China Unicom can be seen.

In the last mile of fiber into the user also encountered the corresponding problems, excavation of pipelines or laying poles, etc. require time and cost, telecom operators are not allowed to share these infrastructure with Google, then rebuild it will result in the original The destruction of the environment, triggering the user's resentment, which has also become an obstacle to the development of Google's optical fiber, these issues are also described in Google's optical fiber development plan.

Many reasons for the impact led to the development of Google's fiber optic plan frustrated, forcing it to switch to wireless technology to solve these problems. But even the introduction of wireless technology still can not bypass the issue of building fiber-optic transmission networks, which still requires investing itself or buying from telecom operators, as is the case with Google's adoption of wired fiber.

Using wireless technology can partially solve the problem of getting into the last kilometer of a home or business, but it introduces new problems. We all know that the wireless technology can provide limited resources. The download speed that a wireless transmitting base station can provide is limited. If building these wireless transmitting base stations everywhere in a residential area will also cause environmental damage, it will also trigger User concerns about radiation, wireless broadband stability, through the wall is also a problem. So, the introduction of wireless technology by Google's fiber-optic program will not help it solve the problem.

The road to technology launch is not always easy. As telecom operators continue to increase the speed of broadband access, they also hit Google's optical fiber plan. As the broadband speeds provided by telecom operators continue to rise, government departments initially hoped to upgrade the U.S. with the Google Fiber Plan The original intention of the user's broadband Internet access has also changed, the chances of subsidies are willing to reduce, so Google's optical fiber plan may be terminated.

Braille Instructions

Reading Braille:
1. Familiarize yourself with the Braille alphabet, which consists of six dots arranged in two columns of three dots each. Each dot or combination of dots represents a different letter, number, punctuation mark, or special symbol.
2. Place your fingertips lightly on the Braille text, typically on a page or surface made specifically for Braille.
3. Feel the dots with your fingertips and identify the patterns to determine the corresponding letters, numbers, or symbols.
4. Move your fingertips systematically across the Braille text, reading from left to right and top to bottom, just like reading regular text.
Writing Braille:
1. Learn the Braille alphabet and practice writing each letter, number, punctuation mark, and special symbol.
2. Use a Braille slate and stylus, which is a tool specifically designed for writing Braille. The slate has rectangular openings to hold the paper, and the stylus is used to press the dots onto the paper through the openings.
3. Place a piece of Braille paper or cardstock into the slate, ensuring it is aligned properly.
4. Hold the stylus like a pen or pencil and press the appropriate dots onto the paper, one at a time, following the Braille alphabet.
5. Lift the stylus after each dot is pressed to avoid smudging or blending the dots together.
6. Continue writing the desired text, moving from left to right and top to bottom on the paper.
7. Review your writing by feeling the dots with your fingertips to ensure accuracy.
It is important to note that learning Braille may require time and practice, as it is a tactile skill that requires the ability to distinguish between the different dot patterns. However, with dedication and persistence, individuals can become proficient in reading and writing Braille.
