Poynting develops 4G antennas

14 November 2012 Telecoms, Datacoms, Wireless, IoT

Poynting Antennas is developing a new range of 4G/LTE antennas. 4G/LTE cellular technology will enable peak data rates of 300 Mbps and higher, and will cause a fundamental change in the role of wireless data for Internet access. It is already in use in parts of Europe and major SA operators are currently running LTE service trials.

LTE requires additional frequency bands since current equipment still needs support on existing bands until all cellular equipment becomes 4G enabled.

Practical tests in Sweden show data rates increasing by many times when two antennas are used instead of one. Antennas are hence becoming fundamentally important rather than just something required in areas of weak signal, according to Poynting’s CEO, Dr. Andre Fourie.

Fourie points out that it is important to ensure that current links and indoor coverage systems use LTE capable antennas, otherwise equipment upgrades will require expensive re-installation or may fail.

New antennas also need to support two LTE bands in addition to existing 900/1800/2200 GSM bands. This implies antennas operating from 790 MHz to 2700 MHz. LTE modems can still fall back to existing GSM bands and unless all frequencies are covered, communications may be unreliable.

Designing products covering all these bands and providing two separate antenna ports in one enclosure is very challenging. Poynting’s LTE antennas are among the first in the world to offer these features.

The first development (A-XPOL-0001) is a cross polarised omnidirectional antenna that covers all the GSM/LTE bands mentioned above. The antenna provides a future-proof solution to ensure reliable links for end-user 4G, 3G and 2G applications. It is window-, wall- or pole-mountable and comes standard with 2 x 5 m of low-loss cable.
