Nokia acquires Internet of Things company SpaceTime Insight

In May of this year, Nokia announced the acquisition of SpaceTime Insight, a California-based Internet of Things startup that provides predictive analytics based on machine learning algorithms. Previously, Nokia’s business in the Internet of Things sector was quite small. By acquiring SpaceTime Insight, Nokia’s determination to further strengthen the Internet of Things business can be seen.

OFweek Optical Communication Network Editor Comments: After the mobile phone business has shrunk dramatically, Nokia has shifted its focus to network equipment. As a senior “player” in the field of communications, Nokia’s involvement in the Internet of Things is clearly well-founded.

Cisco’s $270 million acquisition of AI Enterprise Accompany

On May 2 this year, Cisco announced an agreement to acquire the business intelligence startup Accompany. Cisco will pay $270 million in cash and stock. After the acquisition, the Accompany team will join the Cisco Cooperative Technology Group, which intends to integrate Accompany’s technology. Go to the company’s own collaborative products.

OFweek Optical Communication Network Editor’s Comments: Cisco is a world-renowned network solution provider. The acquisition of Accompany is naturally a concrete manifestation of its enhanced AI capabilities. At present, the AI trend has swept the world. As a world-famous corporate giant, Cisco’s AI is naturally reasonable.

Lumentum wins Oclaro for $1.8 billion

On March 12th, US local time, on the eve of the opening of OFC 2018, the optical device industry announced a major merger and acquisition event. As the industry’s second child, Lumentum won the industry’s third-year Oclaro for $1.8 billion.

Lumentum hopes to strengthen its presence in the optical communications industry by acquiring Oclaro’s own product portfolio. The industry’s general belief that Oclaro’s strengths in telecom optical networks, enterprise networks and data centers is the main reason for its acquisition by Lumentum.

OFweek Optical Communication Network Editor Comments: As the industry’s two well-known optical device giants, Lumentum’s acquisition of Oclaro is undoubtedly a blockbuster in the optical communications industry in 2018. From this acquisition, we can see that the industry concentration is moving forward further. Strengthening its competitiveness in the optical communication industry through mergers and acquisitions has become a mainstream way for industry giants.

Huawei has an accident, why is Cisco nervous? What kind of company is Cisco?

If you use a sentence to explain the strength of Cisco, it is: without Cisco, there is no modern Internet. In the mid-1980s, the US computer network began to emerge. Because the networks used by universities and companies used different protocols and different devices, the demand for multi-protocol routers suddenly came into being. At this time, a pair of teachers and couples at Stanford University in the United States, Leonard Possac and Santi Lerner designed a networked device called “multi-protocol router” that can integrate computer LANs that are incompatible with each other. Together, form a unified network. This “multi-protocol router” is considered to be the real arrival of the human Internet era.

In 1984, Leonard Possack and Santi Lerner founded Cisco to develop network communication equipment. Since its inception, Cisco has entered an industry that does not want to make money. At that time, with the rise of the Internet, the amount of data transmission in the world has increased dramatically, and the amount of voice calls has dropped, and more and more money has been spent. On data communication devices, Cisco is the leader in this field. Cisco has been successfully listed in 1990.

After the listing of many companies, employees of the company will choose to leave the company to start a business or retire. The Leonard Possack and Santi Lerner have also chosen this path. They left the company. Although the founder left the company, but under the revolutionary wave of the Internet in the 1990s, Cisco’s development speed is getting faster and faster, but Cisco really becomes a giant in the industry, and he is a Chambers.

When Chambers joined Cisco in 1991, Cisco’s sales revenue was only $70 million, and the market value was $600 million. But in 1999, five years after he took over Cisco’s sales, Cisco’s sales revenue reached 12.15 billion. The US dollar has a market value of more than 500 billion US dollars, making it the world’s highest market value company. Chambers is therefore called “Mr. Internet.”

Network information at that time doubled on average every four months, which required newer, faster network transmission equipment to support it. As a device supplier, you must constantly innovate and master the latest technology, but no one can guarantee that all technologies can be developed. Under the leadership of Chambers, Cisco on the one hand to strengthen R & D investment, the other is to rely on “buy.” Cisco’s approach is to buy a new company that is developing a new product and, as much as possible, to launch an outstanding new product in the next six to 12 months, and then quickly bring it to market through Cisco’s existing distribution channels.

This strategy is effective. Through research and development and acquisition, the technological advantage is the market advantage, and Cisco has quickly become the dominant player in the network equipment industry. At that time, Cisco’s business scope covered almost every part of the network construction. The market for network devices such as routers and switches that make up the Internet and data transmission is almost always controlled by Cisco. In this market of more than 200 billion US dollars, Cisco is almost the same as “one-of-a-kind”, the market value of the Cisco family is more than the sum of other traditional communications equipment companies.

Junipernetworks (Chinese name: Juniper Networks) was once considered a competitor of Cisco, but its turnover is only 7% of Cisco. In fact, Cisco is fully capable of easily killing junipernetworks, but it did not do so because With juniper, Cisco has saved a lot of trouble with antitrust laws.

Cisco once could not find an opponent with a telescope. Until 2002, Chambers encountered the first Huawei company to exhibit in the United States at the Atlanta Communications Product Show.

What is the impact of charging a laptop for a long time?

It will not damage your battery.

It will shorten its life though, but there is nothing practical you can do about it.

Lithium Ion batteries age in two ways, one is through what is termed “Calendar Life” and the other is Cycle life.  Here is what you need to understand about both:

Calendar life  – the time spent at a given state of charge (SOC) and a given temperature causes a loss of capacity and increase in internal resistance that is proportional to the square root of the time.  Higher SOC imparts greater degradation.  Higher temperature imparts greater degradation.  Keeping your computer plugged in all the time with the battery ensures that the battery stays hot and charged as much as is possible.  If nothing else, turn down the performance of the laptop when you don’t need it to overperform so that it runs cooler.

Cycle life – while you might think that it makes sense to fully discharge the batteries, rather than put lots of little cycles into it, the opposite is true.  Lots of little cycles do virtually nothing to the cells.  100% discharges are the bane of their existance.

So, the reality is, you could optimize battery life by keeping the battery about 50% charged, letting it discharge a bit and then recharging it, and if chargers allowed for it, floating them at a SOC that was not 100%.  However, it is much much easier to just get on with life and use your laptop and not worry too much about this.  Assume your battery costs you $1 a day.  Put that much away for its replacement.  When it is fine on the day you buy your next computer, you have now paid for that new computer, or a good size chunk of it.

Will charging a mobile phone using a laptop decrease the laptop’s battery life?

A laptop battery typically has a capacity of 4000 to 10,000 maH and voltages ranging from 10 to 14 volts.

A cell phone like the iPhone 6 has a 1800mAh 3.7V battery.

First you are right, if the laptop is on charger than charging the cellphone by USB port does not cycle current from the laptop battery. The current comes from the laptop charger and only slows down the rate at which the laptop will recharge.

Second case, if the cell phone is charge from your laptop running on battery. Then the charge will come from the laptop battery and potentially reduce is life by using up charge cycles.

But the  iPhone 6 absorbes 6.7 WH for a full charge (3.7V x 1810 maH)
The laptop lets assume is a 10.2V 6000 maH system and therefore has energy of about 60 WH.

So charging a fully depleted iPhone from the laptop battery will take about 1/10th of the laptop charge.  or 1/10th of a discharge cycle. probably the laptop is rated for 1000 full discharge cycles? So a small part of its life is given up. I’d do it when travelling for convenience or emergency but not every night when at home.

Is it good to keep laptop batteries charged upto 100%?

It’s perfectly alright, you can work no problem

Well, modern batteries are intelligent enough to know whether they are fully charged or not, once they are completely charged the laptop automatically stops charging and starts working with direct D.C supply from the adapter.

I always connect my laptop to charger when i was in home and places where i have facility to connect.

This makes my battery give backup like the new one even after two years.

by the way, it will not increase the temparature. It even cools the laptop, because during charging battery heats up, it makes laptop hotter. If you connect it with charger, laptop works with D.C supply from adapter directly without the involvement of battery. so no heat will be generated from battery.

Lithium battery such as Li-Ion and Li-Pol has no memory effect.

Li-Ion has cycle life between 400 and 1200 cycles (most of them 800-1000), Li-Pol about 500-800 cycles. But it mean full cycle. If you discharge battery by 1% and then charge it to 100% it does not mean full cycle. Only 1% of full cycle.

Lithium battery must not by priming (or formatting). They do not need it. Formatting lithium battery just short their life.
Deep discharge is harmful.

In regard to Lithium battery has no memory effect I recommend charge laptop battery anywhere and anytime you can. Battery can powering standard notebook for about 2-5 hours (ultramobile notebooks can last more than 10 hours). It is very short time so everytime you have oportunity, charge!

But if you use laptop only in home, look for settings and try find function for extend battery life. Many modern notebooks have such function (in various names). It charge battery to maximum 80%.

If your laptop does not leave even your desk, charge battery to 50%, unplug battery from notebook and store it in 15°C. Twice per year check it. If voltage drop under 3 volts per cell, charge it again to 50%.

Carry a Battery Backup

Increasingly, though, the former is just not an option. Laptops with a removable battery, nowadays, tend to be fleet-oriented business machines, and in these cases, the simplest option is a second battery. (Indeed, this can be a good reason to opt for one of these machines even if you’re not a typical business buyer.) Spares can be ordered directly from the manufacturer (we don’t recommend buying third-party batteries), often for less than $100. Simply swap the old battery for the new one once in a while when charging, and bring along the charged-up spare whenever you expect to be away from a power outlet for an extended period.

Another, similar option is to buy an external power pack. While it is also technically a battery, these external power sources plug in to your laptop the same way your charger does. They generally cost between $100 and $200, but come with adapters for use with many different laptop models. They can be used on more than one system, and even for other devices, such as your phone or tablet.

These strategies will help you make the most of the battery you have. If you’re in the market for a new laptop, however, and battery runtime is one of your key concerns, check out our roundup of the laptops we’ve tested with the best battery life.
