Guangdong Radio and Television University (hereinafter referred to as Guangdong TV University) was established in November 1978. It is a new type of higher education institution that uses modern information technology for distance education. It is a public institution of higher learning directly subordinated to the Guangdong Provincial Department of Education and accepts the Central Radio and Television University. Guidance.

"How big is Guangdong and how big is the electric power." At present, there are 19 radio and TV universities at the prefecture (municipal) level, 70 at county-level TV universities, and 5 branches at the provincial level. There are 119 teaching points in the Guangdong University of Radio and Television. The formation of the province is dominated by electricity, and prefectural-level municipal power is the backbone. Grade-based electrification, covering the province's range of integrated planning, grading school, distance management education system and school running institutions, providing graduate education, undergraduate, college, secondary school level education and a variety of non-degree education for the industry across the province And training.

By the end of 2008, Guangdong University of Electronic Science and Technology had more than 160,000 students of various types of higher diploma education. The scale of running schools ranked first among provincial TV universities, accounting for 8.51% of Guangdong's college students in the same period, accounting for the same period of adult higher education students in Guangdong Province. 26.45% contributed 2.5 percentage points to the gross enrolment ratio. The number of graduates of the Guangdong University of Electronic Science and Technology and higher education graduates account for 8% of the total number of graduates of the national TV university system and the total number of students.

At present, there are 4,451 faculty members in the Guangdong TVU system, of which 2582 are full-time teachers, 503 are above associates, and 2,019 are part-time teachers outside the university, including 486 of them with a sub-higher title. During the “Eleventh Five-Year Plan” period, the headquarters of the provincial power university will continue to expand its teaching staff. The total number of faculty and staff in the university will reach more than 700 people, and the structure of the teaching staff will be continuously optimized. The ratio of postgraduate education or master's degree in the faculty will reach 50%. The proportion of professional titles will reach 35%.

Design requirements

The WLAN of Guangdong Radio and TV University is mainly used for wireless coverage of multimedia classrooms. The multimedia classrooms have the characteristics of small area and high density of wireless terminals. Using the traditional fat AP deployment scheme, the interference between the APs and the unbalanced access of the terminals are prone to occur. Therefore, the WLAN project of Guangdong Radio and TV University mainly has the following requirements:

All wireless AP "zero" configuration

Support 802.11a/b/g agreement

Centralized user authentication and management

Data smart local forwarding

Smart RF tuning

Supports load balancing based on users and traffic

Design

Topology plan

Scheme Description

The solution recommends using the NETGEAR WFS709TP as the core of the wireless network to manage all thin APs. All thin APs are connected to the WFS709TP through the 802.3af standard POE power supply protocol under the premise of ensuring the wireless coverage area, which saves the deployment of power lines. The NETGEAR WFS709TP provides continuous wireless coverage with IntelliFi RF management. IntelliFi RF management automatically configures all radio parameters including transmit power level, channel, load balance, and interference avoidance. For low-latency applications such as VoIP, the NETGEAR ProSafe Wireless Controller provides call admission control support for wirelessly transmitted VoIP, voice-aware fast roaming, and strict over-the-air QoS to ensure mobile voice performance. Using sophisticated RF planning tools, administrators can enter the floor plan, number of floors, building dimensions, coverage required, and fault tolerance overlap. The planning tool calculates the RF characteristics of building predictions, determines the ideal location of the AP, and displays the predicted coverage.
