Cellular towers used to rely on base tranceiver station (BTS) equipment, found at the base of the towers, to enable the wireless connection between the cellular network and the cellular phone user. This arrangement lasted for a long time, but wireless operators began to want a more efficient and less costly alternative.
Enter remote radio heads. Remote radio heads cut coaxial feed line losses and increase efficiency and flexibility. Though remote radio heads offer a lot of advantage, they also have a complicated construction and they need to be weather-resistant. Remote radio hear producers therefore need to meet all these challenges.
The following are the remote radio heads produced by TelASIC.
20w Remote Radio Head
This remote radio head operates at 20w at the antenna. It has a frequency of 2.1 GHz, a 1-3 carrier capability, and consumes a total of 110w power.
This radio head weighs 14.9 kilograms and has a capacity of 21 liters, with IP-65 compliant housing for extra protection. It can operate in temperatures ranging from -40 to 55 degrees Celsius (or -47.2 to 131 degrees Fahrenheit), making it resistant to extreme weather conditions. This can make maintenance fairly simpler than one can expect. You can also expect 175,000 hours mean time between failures.
40w Remote Radio Head
This remote radio head operates at 40w at the antenna. It has a frequency of 2.1 GHz, a 1-3 carrier capability, and consumes a total of 180w power.
The 40w radio head is like the big brother of the 20w radio head. This radio head weighs 19 kilograms and has a capacity of 21 liters, also with IP-65 compliant housing for extra protection. It also operates in temperatures ranging from -40 to 55 degrees Celsius (or -47.2 to 131 degrees Fahrenheit), which means it can operate in the same conditions as its smaller counterpart. However, at 150,000 hours, it has a shorter mean time between failures.
A white paper is an informative document written by an authority on the subject matter tackled therein. White papers are often about a particular complicated issue, and the writers (or the organization that commissioned the document) handle the issue through their own philosophy or viewpoint.
White papers used to be more commonly released by government agencies. In recent years, businesses have picked up the practice. White papers released by businesses tend to be more of a marketing effort. These documents aim to persuade or convince an audience to avail of a particular service or product.
The following are the white papers released by TelASIC.
HSUPA stands for High Speed Uplink Packet Access. HSUPA makes data rates with a speed of up to 5.76 mbps possible. These high uplink speeds are delivered from the user equipment to the universal mobile telecommunications system (UMTS) base station and are designed to meet the high expectations and demands from users.
This document lays out how to boost the reception and performance of remote radio heads by combining them with a Node-B receiver. The paper also discusses how different remote radio head receivers can be compared in terms of HSUPA deployment.
Upgrading your WCDMA Base Station for HSDPA
There is currently a drive to upgrade WCDMA Base stations to support HSDPA. The move towards HSDPA is mostly fueled by the desire to grow revenues. Services anchored in HSDPA can bring up new sources of revenues for operators.
To facilitate the upgrade from WCDMA to HSDPA, the radio head in use must be able to transmit higher power. This is where TelASIC comes in. TelASIC’s remote and integrated radio heads are able to facilitate HSDPA transmission. These radio heads are very efficient and enhanced with power amplifier linearization technology.
Lowering Power Consumption
Every month, when you get your electricity bill, you may get overwhelmed by the hiigh costs of power. If you feel like you’re paying too much, there are ways you can lower your power consumption through TelASIC’s products. You can reduce your operational and capital expenses by using TelASIC radio heads, which have a low power consumption. These radio heads are equipped with highly efficient power amplifiers, which significantly reduces the radio heads’ need for electricity.
Designing 802.16-2005 WiMAX or WiBro Radio Head
TelASIC is mainly concerned with building high speed wireless data infrastructure and radio subsystems for WiMAX/WiBRO, HSDPA/WCDMA, EVDO/cdma2000. The document also includes a diagram that illustrates the layout of a radio subsystem, a baseband processing panel, a control panel, and a network interface panel in a WiMAX Base Station.
TelASIC also makes mention of the challenges of creating a WiMAX radio, and how they intend to address each of these challenges. All in all, this document illustrates the innovative practices of TelASIC.
