Lesotho Electricity Company (LEC) is a utility company who transmit, distribute and supply electricity and appurtenant works throughout Lesotho.
莱索托王国是由南非环绕的高空，内陆国家，由河流和山脉网络传播，包括3,500米高的峰。估计的200万居民人口散落在偏远村庄，通常只能通过脚，马或直升机进入。该国覆盖30,355公里（11,720平方英尺）。王国的主要出口之一是水，从Katse大坝派出南非共和国，为其居民提供水电。

LEC had previously made use of a combination of standalone analogue repeaters, cellular systems, and landlines for communication across the country.
除了需要清除通信的情况下，LEC还必须考虑到其用户在日常工作中所面临的业务挑战。为了了解他们的挑战并确定将提供最佳覆盖的合适网站，进行了详细的实地研究。该研究包括整个国家的广泛旅行，通过雪，闪电和雨中的一些最疯狂的地形。找到一个全国多网站链接的最先进的数字移动无线电系统，LEC分手与他们的长期关系Emcom wireless是一个无线电通信业务，帮助找到一个解决方案来缓解这些问题。
“首先了解了哪些用户在日常工作中面临的内容，我们能够利用我们组织内的经验，然后与客户联系，并不仅找到适当的技术，而且也可以满足他们的需求。”

The study and planning was crucial in determining what system would be the best fit for LEC. Project Leader and Director for Sales and Business Development for Emcom, Tony Sipho Sibanda stated "Working in an environment this unique demanded we think out the box and saw us deliver a dependable fully customised solution that's built with the needs of our customer in mind."
一种DMR Tier 3系统from Tait Communications was selected as the vendor of choice. The products are known to be robust, feature rich and secure. Having deployed several similar systems worldwide in this space, Tait Communications were confident in recommending and supporting Emcom in the deployment of the system in Lesotho.
DMR.Tier 3 is an all-digital open standard radio protocol that covers the licensed trunked mode of operation. The protocol's strength lies in its ability to deliver crucial voice and coded data signals (SCADA) over the same network at the same time. This is achieved through optimising the use of frequencies through what is called time slots, via Time Division Multiple Access (TDMA) technology. The technology has the effect of doubling the channel capacity of any network, better utilising limited frequency spectrum, and allowing more volume of data and voice communications.
LEC网络的令人兴奋的特征是与加载的Reditalk Dispatcher集成，加载在Google地图应用程序。这允许总部运营在网络上具有所有无线电和车辆的实时位置可见性，在需要时与特定的无线电交谈，并监控诸如距离事件的站立时间，速度和距离等元素，在一个屏幕上。
Previously when a problem arose in the field, it would often take several days for LEC to pinpoint the location of the problem on the grid, and a further few days to get in communication with head office to dispatch a team with the correct repair tools. The new system has allowed LEC to optimize their grid operations and identify and resolve issues much faster, as communication is now seamless. "We can talk seamlessly from Maseru to Popa on one platform and even see the team's location in real-time as they approach an incident," added Mohlomi Seitlheko, General Manager of LEC.
一种t a time when the bulk of metropolitan cities in southern Africa are gripped by crippling power demand due to several factors, LEC have partnered with Emcom Wireless to both identify the correct digital technology to implement and take the time to design this around growing needs. At the same time, they've ensured a secure deployment of this mission-critical infrastructure. This has been recognized by the Director in the Ministry of Communications Science and Technology, Khiba Masiu, who said of the implementation "The path LEC has taken falls in line with government's vision of optimizing expenditure through infrastructure sharing and we look forward to this network's expansion to other state entities. We fully support this initiative by Emcom and LEC as it's the key to the empowerment of our nation."
