Overview

Background – The Changing Landscape of The Education Market

The education industry, whether that be K-12 or university level, is going

through a fundamental transformation to simultaneously support high

quality instruction, communication and security for students, teachers and

administrators. The industry is moving quickly from a static, classroom-

only world to a mobile, geographically-dispersed model adopting new,

exciting ways of teaching and learning (for example e-learning and MOOCs).

Effective networking access can help achieve educational goals as well as

provide a competitive advantage for schools seeking to attract top students

and faculty. A broadband wireless network is an exceptionally cost-effective

solution and is faster, easier and less costly to deploy and maintain than

wired solutions. The latter is especially critical in the era of reduced school

budgets and smaller IT staffs.

The Solution-eLTE

LTE, the most advanced wireless technology, embodies the optimum

networking solution available. Huawei’s eLTE solution directly addresses

the education industry’s key requirements by providing high-speed, secure,

reliable network connectivity in classrooms, administration offices and

across other dispersed indoor/outdoor venues. What’s more, it is an ideal

tool for engineering communications students and teachers to do further

studies in LTE.

Scenario 1: Huawei eLTE Solution for K-12 and Universities - Wireless Broadband Access

Single-Sub rack Enterprise EPC eCNS600Proven High Performance:   supports up to 40 Gbit/s throughput for 200,000 subscribers.Highly Integrated:   integrates Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW), and Home Subscriber Server (HSS) functions into one 14U-high sub rack; enabling minimal integration efforts in network deployment, reduced risk, and faster time-to-market.

Easy ManagementNetwork Management using a PC Server:   Network management software can be installed on a common personal computer (PC) server, resulting in low cost and easy maintenance.Remote Management of Terminals:   Supports remote monitoring, managing, and updating of CPEs, which reduces the required number of management personnel.

Broadband Data ServiceSupports VLANs:   If the layer 3 VLAN (virtual local area network) has been established, it is recommended that sub interfaces be configured and bound with the VLAN to separate different users and services. This increases the number of sub interfaces to support more VLANs and control traffic in the network, reducing costs, simplifying network management, and improving network security and reliability.

Supports VRF:   This feature separates VPN routes from public network routes and separates routes of different VPNs, which improves data transmission security.

Video SurveillanceUplink-Downlink Configuration Type 0:   This Uplink-downlink configuration type can increase the uplink throughput of UEs and cells in networks that have high uplink capacity requirements.Multiple Carriers:   If multiple 20 MHz carriers are used in one sector, loads can be balanced among the carriers. This feature satisfies the bandwidth requirements in areas where a large number of IP cameras are used and consequently the video surveillance traffic is heavy.

Huawei’s eLTE network provides both LTE and Wi-Fi access so students, faculty and staff can enjoy high-speed networking, surf the internet and exchange ideas anytime and anywhere, even in moving vehicles. This greatly improves communication efficiency and enriches school life.

Thanks to the ultra broad bandwidth of the eLTE solution, with downlink data rates up to 100Mbit/s and uplink rates up to 50Mbit/s, video surveillance and other applications can significantly enhance campus, school and bus route security.

In summary, based on the most advanced broadband wireless technology, eLTE is able to provide flexible services to the needs of the educational institutes.

Scenario 2: Huawei eLTE Solution for Universities - Educational Tool

Huawei eLTE serves as an idea lab test bed for Communication Engineering majors and professionals. Students will gain hands-on experiences on a real carrier-class LTE system with lab projects in the Wireless Communication courses. Instead of doing research with simulation software, professors and graduate students have chance to validate their innovative ideas in the eLTE test environment. It significantly promotes their research capability, and increases the prestige and influence of the university.

Core Network eCNS610SPI-based QoS Profile Control:   uses the shallow packet

inspection (SPI) technique to recognize traffic flows and

provide QoS guarantees. SPI refers to the inspection of

quintuples in IP packet headers at L3 and L4.

Routing Behind MS:   allows terminals, such as mobile

phones, WiFi terminals, or computers, to access an

enterprise network through a wireless device and

allows mutual visits between the terminals and the

enterprise network.

Base StationDL 2*2 MIMO:   two antenna ports are configured in the downlink, and the transmission scheme per user is dynamically selected between spatial diversity and spatial multiplexing to improve the downlink throughput and coverage performance.UL 2x4 MU-MIMO:   UL 2x4 MU-MIMO between UEs and eNodeBs will improve system uplink performance. Up to 2 UEs could be multiplexed to share the same time-frequency resources.UL Interference Rejection Combining (IRC):   a receive-antenna combining technique to effectively mitigate inter-cell interference. It is often used together with receive diversity. In theory, IRC can be used for MIMO decoding, and it is particularly effective for colored interference. Control Channel IRC:   eNodeB supports adaptive switching between IRC and MRC for PUCCHs and PRACHs. When colored interference is detected, eNodeB selects IRC; In other cases, eNodeB selects MRC. This

feature suppresses colored interference, where maximum ratio combining (MRC) does not fit into. CQI Adjustment :   introduces a closed-loop mechanism to compensate for the CQI measurement errors. It allows the eNodeB to instruct a UE to change the BLER target which can be adjusted for CQI reporting, which could maximize the system throughput.Dynamic Scheduling:   based on the nine QoS QCI defined in LTE standards, the nine different QCI classes can be divided into GBR and Non-GBR service. The scheduling solution is required to guarantee the bit rate requirement for GBR services, and enforce the AMBR for Non-GBR services. Scheduling Based on Max Bit Rate:   When a UE accesses the network, the policy and charging rules function(PCRF )or home subscriber server(HSS) notifies the eNodeB of the AMBR and MBR configured for the UE. Then, the eNodeB adjusts uplink and downlink scheduling weights for the UE based on the received AMBR and MBR information. Ultra High Speed Mobility:   the higher the velocity that the UE experiences, the severer the effect of Doppler shift and fast fading that the system suffers. In Huawei RRM solution, the MIMO scheme and resource allocation mechanism is adaptively adjusted to meet the ultra high speed performance requirement. Extended Cell Access Radius:   According to the 3GPP TS36.211, there are four types of preamble format (0-3) for PRACH are defined to support different cell access radius. For format 3, the supported cell access radius is about 100 km, which is used in the large cell scenario to enhance the system coverage.

Northern Michigan University, is a dynamic four year, public

university that has 9200 undergraduate students and 300

full time faculty. It is located in Marquette, Michigan

Northern Michigan’s work with broadband wireless

technology was so deemed so innovative that it resulted in

President Barack Obama choosing the NMU campus as the

site to announce his national wireless initiative in 2011.

To improve upload and download speeds as well as increase

transmission reliability, the university decided to move from

Winmax to an LTE communication solution.

Huawei helps Northern Michigan University build the nation's first LTE ultra-broadband campus network

David Maki,

CTO, Northern Michigan University

Students, faculty and staff are

all benefiting by being able to quickly

communicate and collaborate via the

Huawei eLTE solution. The benefits have

been obvious and we feel well positioned

for our future communications needs.

Northern Michigan University worked with Huawei,

deploying an eLTE network on the campus, providing

7*24 uninterrupted high-speed wireless broadband access

whether the user is in the classroom, a research lab or is

moving across the large campus. The school administration

has also opened the network to the town of Marquette,

which in turn helps defray the LTE equipment cost.

Northern Michigan is well positioned to support its future

communications needs with the Huawei eLTE solution.
