Wireless broadband internet, digital TV & IP Telephony

“K3 last mile” is a proprietary wireless point-to-multipoint technology, allowing fast, secure, and reliable microwave radio access to Internet service providers. This amazing technology provides internet access, digital TV signal and IP telephony to residential or business users in a radius of up to 50 km from a base station.

Technology comparison: Cable broadband vs. K3 Lastmile solution

You can think about “K3 last mile” as a cable in the air!

  1. The Base Station
  2. The Transceiver

To cover a city, we strategically place multiple base stations to cover the widest range possible. Usually, we fully cover a big city with only 2 to 3 base stations. At least one base station is connected to a global internet backbone. We then use base stations to relay the signal and expand our coverage over hundreds of kilometers.

The base station then relays the signal to the Transceiver that is mounted on a business or residential, multi or single building. From that point on we use the same technology as regular cable operators so you can keep your routers, switches, and Wi-Fi without changing anything.

We provide amazing speed of up to 1 Gbps per transceiver and can scale up with simply adding more. This way we provide shared or dedicated bandwidth suitable for different levels of users. Our connections are safe and reliable. No weather or other interferences have shown up on the Sierra Leone testing ground.

Connecting Africa

This technology is perfect for connecting overcrowded urban areas in developing countries such as the ones in Africa. Because of their exponential growth and lack of planning for broadband infrastructure there are now millions of business and residential buildings without any data cable connected to them. And digging trenches to lay cables is practically impossible at this stage of urbanization.

These clients therefore need to rely on outdated and overloaded mobile networks that can’t deliver dedicated speed or reliability. They are mostly still 3G connections and that is impairing competitiveness on global markets, aggravates e-learning and slowing down digital entertainment.

The World Bank stated that it would take over $100 billion and more than a decade to connect Africa.

With such low CAPEX and OPEX we can provide affordable connectivity and high-quality entertainment where it was perceived impossible until now. And we can even do it in only half a year.

Internet connectivity

Our local market research shows that internet speed is the most desired aspect of internet connectivity. There is a wide gap between the current and the desired internet speed

Our technology can provide up to 20x faster speeds than currently desired. But with more speed, there comes more data usage. That is a big issue for mobile operators that is why they are offering only limited data packages. K3 last mile on the other hand allows for unlimited data packages that will become increasingly more important with faster speeds.

Then there is the reliability and the speed. Our residential solutions focus on shared internet speed with guaranteed at least 60% of the acquired package at peak times. This is European standard internet service.

With dedicated speed we cover the businesses that rely heavily on a stable and fast internet connection, such as banks, hospitals, hotels, and governments.

TV and entertainment

Most of Africa uses satellite TV with the standard issue that it just doesn’t work well while it’s raining, probably the time you would want to watch TV the most. Providing digital TV through internet bandwidth usually clogs up the network, making it slow and unstable. There is also additional pressure on the ISP provider as they need to serve each client full bandwidth even if everybody is watching the same movie. K3 last mile reproduces the stream locally in it’s own systems and distributes it in its own network. There are no additional bandwidth charges to the ISP even with millions of viewers. There are over 150 digital channels in the system already, providing unprecedented quality, information, and entertainment to Africa’s cities.

IP telephony

With mobile on the rise, stationary telephony is slowly loosing steam, yet IP telephony is still valued in large corporations and enterprise level businesses. IP telephony provides additional information on your company phone usage. You can see how many calls each salesperson makes, you can record conversations with clients to prevent unnecessary disputes, and you can use your existing infrastructure as it works with phones, fax machines, alarms, and credit card readers. IP telephony lowers costs and allow for better mobility, worldwide access, and future versatility.

K3 telecom

K3 last mile technology is developed by K3 telecom AG, a Swiss based telecom company. The technology has been in the works for more than a decade and has been already successfully deployed in the USA, Canada, Spain, Czech Republic, Slovenia, Mauritius, Liberia, and Sierra Leone, the last one being a fully-fledged telecom operated by K3.

K3 last mile vs Mobile Network based ISP connections

Compared to a mobile tower that operates on 20 MHz to 40 MHz, K3 technology operates on 600 MHz. In means of speed this would translate to 70 Mbps on mobile to 17,000 Mbps on K3, roughly 240 times the performance.

Mobile towers have connection limits of around 200 to 300 people, while K3 can connect 5000 clients to one base station. It also enables us to know exactly who is connected to which tower and limit the speed for each connection individually.

There is a 25 to 50 times difference in coverage range as mobile towers allow only for 1 to 2 km radius. K3 can guarantee full speed and stability for clients up to 50 km away.

With less towers, CAPEX and OPEX costs are lower in operating on K3 technology.

K3 frequencies requirements

K3 technology operates on the radio frequency spectrum (RF) between 2 and 42 GHz. It uses 2 frequencies, one for downstream and one for upstream with the optimum frequencies being between 200 and 500 MHz for downstream and between 75 and 400 MHz for upstream. Being outside the mobile frequency ranges the frequency licensing is far cheaper allowing for even lover OPEX.
