Wispernet — wireless internet provider in the Southern Cape and Karoo
Wispernet was founded in George in 2007 on top of an unusual asset. Its sister company Hilbert Electronics had spent 42 years moving from television repair into two-way radio, and in doing so had built repeater stations on mountain high sites across roughly 40,000 square kilometres of the Southern and Eastern Cape. Wispernet inherited those positions and turned them into a wireless broadband network reaching farms, towns and municipalities the fibre operators have never costed.
Key facts
| Who they are | A licensed wireless internet service provider founded in 2007 as the broadband arm of Hilbert Electronics, a Southern Cape business that had traded for 42 years, first in television repair and then in two-way radio |
| Why the heritage matters | Two-way radio meant repeater stations on remote mountain high sites across roughly 40,000 square kilometres. Those positions are the hard part of building a wireless network and they already existed, which is why Wispernet covers rural ground that fibre operators have never costed |
| Coverage | The eastern Western Cape from L’Agulhas to Montagu, the Garden Route through to Plettenberg Bay, and inland to Oudtshoorn, Uniondale, De Rust, Prince Albert, Ladismith and parts of the central Karoo |
| Services | Wireless broadband with fibre-fed backhaul, VoIP telephony, hotspots, email accounts, wireless networks, VPNs, domain hosting and CCTV camera systems |
| Head office | 33 Hibernia Street, George Central, George, 6529, Western Cape, with branch offices and agencies across the region |
| Leadership | Alewijn Joubert is named as chief executive and Lohan Oosthuizen as managing director. The company also publishes its VAT number and names its auditors, which is more corporate transparency than most providers in this directory offer |
| Customer rating | 3.0 from 154 Google reviews on a profile matching the domain and the George address. That is a large sample and a middling score, published exactly as found. The recurring review subjects are outage updates and rural remoteness alongside quick installation and network stability |
| How to read that score | A rural WISP is judged on what happens during an outage, because a farm on a wireless link has no second option to fall back on. Ask specifically what the fault-reporting route is, what the target restore time is for your area, and whether the company publishes outage notices — the reviews suggest that is where expectations are set or missed |
| Pricing | Quoted per address after a coverage check, since wireless depends on line of sight to a high site. VPN services are advertised from R165 a month |
| ICASA licence | The company describes itself as a licensed internet services provider; the licence reference is not published on the site |

The towers already existed, which is the whole story
Wireless coverage is a line-of-sight question, and line of sight is decided by where the transmitters sit. That is why this provider covers ground its competitors do not: the high sites came from four decades of two-way radio work, long before anyone was selling broadband over them, and they sit on mountains chosen for radio coverage across the Karoo and the Garden Route interior. For a farm outside Prince Albert or a business in De Rust, that history is the reason a connection is available at all. The score deserves a straight read rather than a defence. Three point zero across 154 reviews is a substantial body of feedback and it is published as found, because genuine negative sentiment is never softened here. What the reviews actually discuss is instructive: installation and network stability come up positively, while outage communication and the realities of remote servicing come up negatively. That is the classic rural WISP profile, and it tells you exactly what to test. Before signing, ask for the fault-reporting route, the realistic restore time for your specific area, and whether outages are announced proactively. If the connection carries your business phones as well, ask what the failover is, because a wireless link and a VoIP service on the same link fail together. Compare providers and networks in the wireless directory.

Start with a coverage check on the exact address, because wireless needs line of sight to a high site and a neighbouring farm is not evidence. Ask what the target restore time is for your area and how outages are communicated, since that is what the reviews are really about. If VoIP will run over the same link, establish the failover plan, because the connection and the phones fail together otherwise.
