Infoblox identified the challenges Communication Service Providers (CSPs) face in transitioning to distributed cloud models, as well as the use cases for multi-access edge computing (MEC), 5G New Radio (NR), and 5G Next Generation Core (NGC) networks. “Distributed cloud models such as 5G and multi-access edge computing networks have the potential to drastically change the CSP industry, delivering high-bandwidth, low latency services to network customers,” said Dilip Pillaipakam, Vice President and GM of Service Provider … More
As 5G deployment plods along in Canada, the next-generation wireless standard has already been adopted by healthcare practitioners in China. At the Huawei Global Analyst Summit 2020, Dr. Lu QingJun, director at China-Japan Friendship Hospital and a full-time remote healthcare practitioner, shared his thoughts on the impact of the higher quality networks on hospitals of the future.
Lu gave a personal example by describing one of his previous remote cases at a primary care hospital. In his scenario, the patient had to wait for 25 hours to receive a consultation, due in large part to the 12GB of data that had to be sent over the network. Lu said that with 5G, that time can be cut to just “dozens of minutes”. The dataset is amplified for patients who need multiple tests, such as CT scans and electrocardiograms.
When describing telemedicine, Lu precited that data, technology, and intelligence will become inseparable from healthcare. Although the course has been set, Lu also noted the perpetual battle to improve privacy and secure data transmission, all of which require new infrastructure for the intelligent hospital.
“We’ve always said that it’s not necessary to replace 4G with 5G in all cases, so we need to identify those cases where only 5G is able to support,” said Lu, noting that the introduction of technology built on 5G should not impede the efficiency of existing workflows.
The conversation then naturally leads to whether existing technologies like fibre internet could fill these roles.
“Hospitals already have fibre access, so do we actually need 5G?” Lu asked rhetorically. “You only say that because you don’t understand 5g…we need mobility, but not only that, we need to upgrade our equipment and currently our equipment is wired.”
Network infrastructures will be the backbone to facilitate new communication demands. Thus, its development needs to keep pace with the ICT industry. Because telemedicine is still relatively new, the industry needs to generate new scenarios as testbeds for these newer technologies, Lu explained. These new use cases, whether they’re generated naturally by demand or synthetically, will help push along the development of these new technologies.
For example, 5G’s bandwidth massive bandwidth improvements could remove the bottleneck present in real-time communication and medical imaging. Increased bandwidth enables more immediate, higher quality remote checkups. It could also simplify the diagnostic process by enabling services like real-time remote full-body scanning, a procedure that generates large image files.
Another factor that affects performance is latency. The ITU-R defined Ultra-Reliable Low Latency Communications (URLLC) as one of 5G’s main applications. In a highly-technical and mission-critical application like healthcare, low latency is a key concern.
“The 4G technologies are not enough to meet our needs,” Lu pointed out. “In the past, we compressed the data to make it fit into the smaller pipe. And the 4G latency was not acceptable. For 5G, the latency is very low. It’s almost a real-time so the doctors can get real-time data transfer to provide better services to the patients, especially when we talk about the complex and difficult.”
He specified remote monitoring, remote analysis, remote robotics, and remote visit as crucial areas of focus. He said that while doctors understand the benefits of remote practices, vendors are not yet prepared to manufacture this equipment due to inadequate certification and qualifications.
There are more than 13,000 secondary–or specialist–hospitals in China, and adding telemedicine capabilities to them all would incur significant cost. With that said, developing remote healthcare also stimulates new business opportunities for carriers.
Moreover, Lu said that the entire network stack–the slices, transport network and edge computing could all benefit from being supported by 5G technologies. The benefit isn’t limited to telemedicine but the communication industry as a whole.
In addition, 5G could help to streamline a hospital’s logistic operations like payment. China’s mobile payment system is the most established in the world by far. In 2019, over 81 per cent of the country’s smartphone owners frequently pay through proximity mobile systems such as QR codes. But while China’s digital commerce is being developed at an explosive pace, hospitals of the future will demand more robust transaction support.
“We need to have innovation in the healthcare service provision,” said Lu. “And and we also need to have some payment assurance like basic medical insurance, commercial insurance, and also some banking services support. And that has high requirements on computing on storage and on data processing. These requirements will only be satisfied by adding new ICT technologies.”
The ubiquity of 5G will cover everything from IoT sensors, to smart devices, to cloud communication. But the technology that spawned from 5G development can extend well beyond just global networks. At IBM Think 2020, MIT Professor Muriel Médard spoke about how satellites can also benefit from the development of 5G.
One of 5G’s plethora of features is a coding technique called Random Linear Network Coding (RLNC). Médard defined network coding as a “mathematical manipulation of data that to be reliably retrieved, reliably represented and transported in a network”.
In essence, through complex encoding and decoding techniques, RLNC can reassemble lost packets in a data stream by the receiver. This reduces the need to resend data when they become lost. It can increase reliability when sending sensitive information like financial data, as well as be applied to monitor sensors and vehicles in remote areas.
As a backgrounder, to transmit large quantities of data between two devices, the information must first be cut up and encapsulated into packets. Sending data via small packets provides many benefits, including higher efficiency and increased reliability. If data becomes corrupted or lost during transmission, only the affected packets need to be resent rather than the entire dataset.
In urban centres, radio towers are relatively near the user, thus creating stronger signals that are more resistant to environmental factors. In satellite networks, however, the long-distance between the sender and the receiver renders it vulnerable to disruptions from inclement weather. In addition, high latency compounds the finicky signal; if data becomes lost during transit, it will take longer to resend.
Despite its shortcomings, underserved communities in Canada and around the world rely on satellite to stay connected. Due to geographical and business limitations, it’s not always feasible to pull landlines and install towers to these locations. It’s critical for satellite network technologies to advance in parallel with the networks back on the ground.
Former senior government figures voice security fears as PM chairs meeting of NSC
Former ministers have sounded their final warnings to Boris Johnson about the Chinese telecoms firm Huawei ahead of his expected decision on whether it will play a part in the UK’s 5G network.
The prime minister will chair a meeting of the national security council (NSC) later on Tuesday before making a judgment on the firm’s future in the country after months of concern around security, including from the US president, Donald Trump.
5G is the next generation mobile phone network and it promises much higher connection speeds, lower latency (response times) and to be more reliable than the creaking 4G networks we have now.
Huawei is a Chinese telecoms company founded in 1987. US officials believe it poses a security risk because the Chinese government will make the firm engineer backdoors in its technology, through which information could be accessed by Beijing. Donald Trump has banned US companies from sharing technology with Huawei and has been putting pressure on other nations to follow suit.Continue reading...
Since we are in the business of securing our enterprise customers’ infrastructures, we keep a close eye on how the security and encryption landscape is changing so we can help our customers to stay one step ahead.
In 2019, ransomware made a comeback, worldwide mobile operators made aggressive strides in the transformation to 5G, and GDPR achieved its first full year of implementation and the industry saw some of the largest fines ever given for massive data breaches experienced by enterprises.
2020 will no doubt continue to bring a host of the not new, like the continued rash of DDoS attacks on government entities and cloud and gaming services, to the new and emerging. Below are just a few of the trends we see coming next year.
Ransomware will increase globally through 2020
Ransomware attacks are gaining widespread popularity because they can now be launched even against smaller players. Even a small amount of data can be used to hold an entire organisation, city or even country for ransom. The trend of attacks levied against North American cities and city governments will only continue to grow.
We will see at least three new strains of ransomware types introduced:
- Modular or multi-leveled/layered ransomware and malware attacks will become the norm as this evasion technique becomes more prevalent. Modular attacks use multiple trojans and viruses to start the attack before the actual malware or ransomware is eventually downloaded and launched
- 70% of all malware attacks will use encryption to evade security measures (encrypted malware attacks)
Slow Adoption of new Encryption Standards
Cyber attacks are indeed the new normal. Each year brings new security threats, data breaches and operational challenges, ensuing that businesses, governments and consumers have to always be on their toes. 2020 won’t be any different, particularly with the transformation to 5G mobile networks and the dramatic rise in IoT, by both consumers and businesses. The potential for massive and widespread cyber threats expands exponentially.
Let’s hope that organisations, as well as security vendors, focus on better understanding the security needs of the industry, and invest in solutions and policies that would give them a better chance at defending against the ever-evolving cyber threat landscape.
