Program and Technical Details

What is the rationale behind World Mobile's use of hexes on the map?

World Mobile adopts hexagons as a visual representation due to their efficacy in breaking up lines, thereby providing a clearer and more accessible visualization of data patterns. This approach is especially beneficial when dealing with curved patterns. This choice is reminiscent of Uber's H3, a development aimed at optimizing ride pricing and dispatch while enhancing the visualization and exploration of spatial data.

What is the World Mobile spectrum area?

The spectrum areas are telecommunications-defined geographical areas where operations can occur. In July 2023, World Mobile secured spectrum in the USA of up to 20MHz of spectrum in markets within California, New Mexico, Nevada and Utah.

What is the difference between World Mobile spectrum and CBRS?

World Mobile spectrum encompasses any spectrum for which World Mobile has obtained licenses. Currently, we have obtained licenses for Band 71. This spectrum allows for flexible power usage, with a legal limit of 1000 Watts (approximately 1 kilowatt), even though World Mobile typically uses much less, offering long-range coverage of several kilometers. On the other hand, CBRS (Citizens Broadband Radio Service) is a higher-frequency spectrum made available by the government for cellular use. While it has limited range, covering about a mile and a half (approximately 2.4 kilometers), it operates at 3.5 gigahertz. The hexes are approximately 0.7 miles across (approximately 1.1 kilometers), and when multiple hexes are nearby, they may overlap, which is intentional to provide users with seamless coverage, ultimately leading to meaningful coverage.

By utilising Band 71 and Band 48 (CBRS), the network establishes a robust hybrid dynamic network. Operating on a 600-megahertz frequency, Band 71 serves as the backbone for extensive long-range coverage. Simultaneously, CBRS facilitates efficient offloading to ensure a seamless and comprehensive coverage experience for our users.

Does World Mobile have any experience with Band 71?

World Mobile has previously harnessed Band 71 in Kenya, operating it as an unlicensed spectrum with specific power restrictions. Throughout this phase, we conducted extensive testing on various devices and handsets. This experience significantly influenced our decision-making process as we prepared for our rollout in the US.

Can you explain the difference between the hexes covering Band 71 and the hexes in the CBRS layer?

Hexes covering Band 71 operate on a 600 megahertz frequency, offering good coverage and range but limited bandwidth. In contrast, the CBRS hexes operate at 3500 megahertz, providing shorter range but broader density and bandwidth for users.

Are there specific installation requirements for the Band 71 unit and the CBRS unit?

Yes, there are distinct installation requirements for the Band 71 and CBRS units. The Band 71 unit necessitates installation by a licensed installer and an additional requirement for electrical engineering approval. For the CBRS unit, while the requirements are somewhat less clear-cut, World Mobile provides comprehensive support throughout the installation process. It's important to note that both units must undergo approval by a licensed engineer to ensure compliance and optimal performance.

What are the available configurations for CBRS coverage?

Our current stock offers two configurations for CBRS coverage. A single AirNode unit provides 180-degree coverage, suitable for installations on the side of a house or projecting into a specific area in front. If you desire 360-degree coverage, you can purchase two AirNodes and mount them back-to-back on your roof/ higher surface.

Is the hardware used by World Mobile branded or customized?

The hardware provided by World Mobile is not branded or customized. Our philosophy is to use off-the-shelf hardware to facilitate efficient and fast deployment without the need to reinvent the wheel.

Can people with a SIM from another operator connect to a World Mobile AirNode?

World Mobile as a GSMA Operator member is in the process of agreeing both inbound and outbound roaming agreement. For the immediate term only World Mobile or RINA sims will be able to attach to World Mobiles AirNodes.
