乌审旗云学堂千点集中部署，轻巧运维
场景痛点
✓ 乌审旗下辖几十所中小学，最远的学校离旗县电教中心有近200公里。 且偏远学校的老师少，且技术水平一般不如县里的，出了问题有时候要 驾车200公里到学校维修，更换配件，工作量大。
CPU：Intel 第六代i5及以上 内存：4GB及以上 硬盘：1TB HDD及以上 系统：Win7（非Home版）
全千兆即可 推荐E528/E552
学生通过网络连接，访问在云主 任课老师使用的设备，以及教学互动功能。 提供设备间以太网互联。
部署：H3C云学堂部署服务 督导：H3C云学堂督导服务 维保：H3C软件技术支持服务
多数情况下，学校没有独立采购权，设备采购是由区县教育局统一集采，PC类采购，学校不单独立项运作 项目，一般流程如下：
了解各区县预算
有预算
拜访电教站（装备中心）站长 动作：价值传递、商务推进 目的：初步认可产品和人
市级样板点参观 目的：增加客户的感性认识 解决技术疑问
局长认可：走项目流程
认可 教育局局长
只做九年义务教育（初中、小学）计算机教室场景！
