Neratel

[yeokiwi]

In singapore, there are only 4 entity that require transceiver and nms in a island wide scale.
The 3 telco (for their 3g handset and cross island) and spf/scdf. The 3 telco have their own technical staff and buy most of their own equipment partner(eg huawei,cisco).
Spf/scdf coverage is maintain and support by ST elec.

Not very sure though but..

Huawei and Cisco wireless products are quite different from Nera. Nera offers long distance wireless infrastructures at very high RF frequency. (up to 60GHz) and directional.

Huawei and Cisco typically deal with frequencies that are less than 5GHz(800Mhz, 900Mhz, 1800MHz, 1900MHz , 2.4G...) that are deployed in large number in urban areas.(you probably can spot one easily in underground carpark). They are typically short range and unidirectional.

I suppose some Singapore offshore islands, light houses will have Nera kind of RF equipment installed.
