Backhaul
Our elegant wireless backhaul solutions have helped our clients to face multifarious challenges and we are proud on being able to raise them on every challenge. Teaming best people with good understanding in technology and business we have advanced with best and reliable products. At RFIC solutions we are determined to knock down all challenges with innovative solutions.
Hunger towards data growth is increasing exponentially, challenge to develop a faster and efficient data networks is essential. RFIC’s wireless access and wireless backhaul solutions is helping in building 4G and 5G wireless systems to keep pace with his demand.
What Is a Backhaul?
Getting large chucks of data from end user with good speed and with less bit error is a challenge in 5G system. Using wireless communication systems to achieve this data transfer from end users to a node in large networks like internet or branded large business networks, federal agencies or academic institutions is what a backhaul does.
Our Point to Point (PTP) solutions are helping highly critical applications in formidable conditions for all demanding users. Simple and efficient performing solutions with better security are accessible for defense and government applications. The PTP solutions are your connections to what matters, no matter what.
.
Deploying RFIC’s Point to Multipoint (PMP) solutions will provide wireless service to connect millions of people worldwide. Network operators can provide wireless high-speed data services to residential and business customers using PMP solutions. These PMP vary with scale considering needs and area to connect.

Wireless backhaul is easily deployable, and allows moving points of presence, but, these wireless connections are slower, acquire spectrum that could be used by user devices (mainly at 5.8 GHz devices proliferate), require more truck rolls (typically three times as many) as wired backhaul, and has limitation in bandwidth. Wireless backhaul is generally considered as an initial or temporary measure.
Backhaul Technologies
- Free-space optical communication(FSO) is a technology where light is used to transfer data in free space wirelessly. Widely applied in telecommunication and computer networking.
- Point-to-point microwave radio relaytransmission (terrestrial or, in some cases, by satellite)
- Point-to-multipointmicrowave-access technologies, such as LMDS(Local multipoint distribution service), Wi-Fi, WiMAX(Worldwide Interoperability for Microwave Access), etc., can also function for backhauling purposes.
- DSLversions, such as Asymmetric digital subscriber line (ADSL), Very high speed digital subscriber line (VDSL) and Single-pair high-speed digital subscriber line (SHDSL).
- plesiochronous digital hierarchyand Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) interfaces, such as (fractional) E1/T1, E3, T3, STM-1/OC-3, etc.
- Ethernet in LAN, WAN, and MAN.
- Voice over IP telephonyover dedicated or public IP network.
PTP and PTMP Communication.
Point-to-Point (PTP) communication and Point-to-Multipoint (PTMP) communication is an lesser known terms to common users, but they have great importance in the field of telecommunications. Two-way radio is a classic example of PTP communication. On the other hand, radio and television transmissions are examples of PTMP communication. These communication systems have their distinct capabilities and limitations. We will understand both technologies in better way in the following sections.
Point-to-Point (PTP) Radios
The main advantage of PTP radios involve simplicity in installation, secure wireless connectivity, long range and mainly cost effective in data transmission. As the name represents, Point to Point radios are always in pairs and always communicates between nodes or endpoints. This kind of setup is capable of delivering good Ethernet data rates up to 100 Mbps and is also perfect for substation connectivity applications and high performance backhaul.PTP radios can be modeled to communicate over a range of 50 kilo-meters which ensures good connectivity in remote and rural areas.
Point-to-Multipoint Connection
A multipoint connection involves the link from a single transmitter being shared between many receivers. It is essential to make a note that in a PTMP connection, receivers never communicate with each other but instead all have a single connection with the main core or access point. Internet service providers (ISPs) will commonly go for PTMP connections. Internet service providers will have a radio transmitter on top of a tall building or hill station with a clear line of sight to multiple receiving radios. PTMP networks operate in both unlicensed and licensed frequencies (E-band,42GHz,23GHz etc) bands with speeds of up to 1Gbps. This type of connection is ideal when distributing less data to more recipients
