Ruijie builds a new mobile medical network for Jiangsu Cancer Hospital

At 4 o'clock in the morning, Los Angeles and Kobe became the source of many young people's blood, but the hospital at 4 am is the daily routine of the nurses. They maintain order in all corners of the hospital; they wear needles and carry the surgery to the end; they take the lead and rescue the emergency patients... They shuttle in the ward, can't wait for three heads and six arms... Every time the tour ends, they are still thinking about what else they can do better.

Nowadays, with the continuous promotion of digital medical care nationwide, the complicated transcripts of medical records have become history, and network-based mobile medical care is becoming more and more popular at hospitals at all levels. However, as medical care becomes more and more dependent on the network, the requirements for wireless signal quality are getting higher and higher. For critically ill patients such as tumors, patients and their families tend to be more anxious, and accidentally may lead to serious medical disputes. Jiangsu Cancer Hospital (Nanjing Medical University Affiliated Tumor Hospital), with the help of Ruijie Networks “ Mobile Medical Zero-Roaming Solution”, has created a “healing network” that makes medical services more “intimate”.

Mobile care does not require wireless network upgrades

Jiangsu Cancer Hospital is the only provincial third-grade hospital in the province of Jiangsu Province. It is responsible for the prevention, diagnosis and treatment of nearly 80 million people in the province and some cancer patients in neighboring provinces. There are 1,161 actual beds in the hospital, and there are 30 wards. The annual outpatient volume is about 270,000, and the annual hospitalization is nearly 53,000.

With the continuous development of hospital business, the need to improve the efficiency of medical services and improve the relationship between doctors and patients is becoming more and more urgent, and the traditional clinical nursing model can no longer meet the needs of modern quality care. To this end, the hospital began to prepare a hospital-wide mobile care system in the second half of 2014. After the large-scale launch of the business system and PDA terminals, higher requirements were placed on the hospital's information network, especially the wireless network. Therefore, the hospital decided to build a wireless network covering all the wards of the ward, so that doctors and nurses in the hospital can use the hospital information resources conveniently and efficiently. The wireless network needs to meet the requirements of simple access authentication, full coverage, no dead angle, high rate, fast access to medical images, and uninterrupted service.

Ruijie "smart points" wireless display strength

In order to find out the specific situation of the mobile nursing system of Jiangsu Cancer Hospital, Ruijie engineers carried out a large number of exploration work in the early stage. The wall of the ward is thick, the structure is complex, the inter-AP interference, the system is dropped, and repeated verification are the reasons for the poor mobile medical experience. Under the architectural pattern of the ward, although the traditional placement type AP can be deployed in the corridor, the signal in the room will be very poor, and the signal at the corner and the toilet will not be received. However, if room-type deployment is adopted, although it has the advantages of strong signal and good roaming, it has many drawbacks such as many accessories, complicated deployment, and low performance.

Faced with this typical ward scenario, the Ruijie Mobile Medical Zero-Roaming Solution, which combines the advantages of “placement + room division”, is the optimal solution. The "smart" architecture of the antenna into the room ensures that the signal in every corner of the room is "full", and the beautified antenna not only eliminates the patient's radiation concerns, but also perfectly realizes the wireless coverage of the corridor.

In terms of roaming, after the program is launched in the hospital's 27 business wards (including the operating room, ICU), the wireless signals of the whole network are from the smart base station. After the amplification, distribution and optimization of the signal of the intelligent unit, let one The wireless coverage of the ward is in the same environment of the same channel and the same frequency band, thus achieving "zero roaming". Hospital nurses hold PDAs, no matter how the location moves, they can always ensure that the signal is not interrupted, making the mobile healthcare business smoother.
